Twenty-four male lambs with an average weight of 28.73±3.64 kg and age of three months were assigned to four treatments with 6 lambs for each treatment in a completely randomized design. The treatments included: the control (basic diet), treatment 1: basic diet + 10 grams of supplement (60% cumin, 30% coriander and 10% peppermint), treatment 2: basic diet + 10 grams of supplement (45% cumin, 45% coriander and 10% peppermint), treatment 3: basic diet + 10 grams of supplement (30% cumin, 60% coriander and 10% peppermint). Blood was taken from the jugular vein of the lambs at the end of the experiment. DMI was not affected by treatments. Average daily gain (ADG) in the treatment 1 was higher than that of control treatment. Hemoglobin, PLT, RBC, and WBC, percentages of lymphocytes, monocytes and neutrophils were not affected by the supplements. No significant difference was observed between the experimental and control treatments in terms of blood glucose and triglyceride concentrations. Blood urea was higher in the treatments 2 and 3 than in the control. Aspartate aminotransferase and alanine aminotransferase increased in treatments 2 and 3 compared to the control. Alkaline phosphatase and gamma-glutamyl transpeptidase in the treatment 3 were different from the control. Glutathione peroxidase and superoxidase dismutase did not change, but the antioxidant capacity in experimental treatments decreased compared to the control. The results showed that the addition of 10 gram of cumin, coriander and peppermint mixture with ratios of 30, 60 and 10, respectively, improved the performance of Roman lambs and feed efficiency without having an adverse effect on blood metabolites.

Extracts and essential oils of medicinal plants have been able to exhibit their role in impacting growth performance, the microbiota of the digestive tract, digestion, and immunity. The beekeeping industry is also facing many challenges such as pests and diseases. The use of chemical drugs not only raises microbial resistance but also declines the marketability of bee products with residues. Encountering suitable and effective natural alternatives has always been one of the concerns of all researchers. Medicinal plants with numerous compounds have been able to reveal their positive influence on farm animals and can be used as a reliable alternative. The use of nectar and pollen of medicinal plants by honeybees not only controlled pests and improved honeybee diseases but also enhanced the quality of products produced by this beneficial insect. There is a lot of scientific information related to antioxidant properties of bee products, but it is vital to provide a general view of the effects of medicinal plants on this industry and to improve the antioxidant properties of bee products.

In present study the effects of chicory, turmeric, artichoke and sage powder on yield, egg quality and fatty liver status in laying hens fed high energy and low protein diets. A total of 270 LSL laying hens at 80 weeks of age were randomly assigned to 5 treatments, 6 replications and 9 birds per replicate. Experimental treatments were included high energy (3000 kcal/kg) and low protein (13%) diet as control, and four diets containing 0.15% of chicory stem and root powder, turmeric rizhom powder, artichoke leaf powder or milk thistle powder. The results showed that treatments decresed feed intake and turmeric increased egg weight (P<0.05). Yolk color, white weight, and shell weight were affected (P<0.05) positively by medicinal plants. Diet containing turmeric significantly reduced blood glucose compared to control diet (P<0.05). The effect of treatments on biochemical and hematological parameters of blood was not significant (P>0.05). Abdominal fat weight was significantly lower in birds received milk thistle diet (P<0.05). The results showed that the medicinal plants used in the present study had no effect on bird’s performance however milk thistle powder by lowering the abdominal fat and with lower histological and hemoragic scores had more potential for improvement of fatty liver and more researches with higher level of milk thestle is needed.

Industrial poultry farming on a large scale and intensively has increased the possibility of disease outbreaks. Studies have shown that the use of antibiotics, in addition to environmental threats, causes microbial resistance in the body (Yakhkeshi et al. 2011). The presence of chemical residues in poultry products and its impact on human health was one of the reasons for the ban on the use of antibiotics in 2006 (Garcia et al. 2007). Much research has been done to find suitable alternatives to antibiotics. Essential oils and plant extracts with a variety of biological and physiological compounds have a very high potential for their use as new medicinal compounds (Hussain et al. 2008). Useful properties of medicinal plants are related to the presence of secondary metabolites in them (Efterpi et al. 2012). In addition to improving bird growth and production, medicinal plants have positive effects on health status parameters (Grashorn, 2010), intestinal microbial population (Bolukbasi et al. 2008), serum concentration of antibodies to viral diseases (Toghyani et al. 2010) and biochemical and hematological parameters (Toghyani et al. 2010). Among the medicinal plants, cinnamon, marjoram and pepper are aromatic herbaceous plants that are of great importance and have effective healing properties. In some studies, consumption of cinnamon in the diet has caused weight gain, decreased feed conversion ratio and improved liver function in broilers and mice (Mehdipour et al. 2013; AL-Kassie, 2009). Giannenas and Et al. (2005) reported that consumption of marjoram extract improves the performance of broilers. Capsaicin in pepper increases intestinal and bile secretions, increases the activity of pancreatic enzymes, slows the passage of substances in the intestine, and increases the absorption of nutrients (Farrell, 1978). Platel and Srinivasan (2003) reported that consumption of capsaicin by 0.15% in the diet increased salivary amylase secretion in mice; it also increased gallic acid salts by 17%. It has been reported that the consumption of several medicinal plants simultaneously has a greater effect on the production, functional and health parameters than the consumption of one medicinal plant alone (Mehdikhani, 2015). Farrokhnia et al. Reported in 2020 that the consumption of a mixture of Thymus vulgaris and Echinacea angustifolia extracts was reduced due to a reduced conversion ratio of broilers compared to separate consumption. According to the above, the aim of this study was to investigate the effect of consumption of a mixture of cinnamon, marjoram and pepper extracts on performance, weight and relative length of gastrointestinal tract, enzymes and blood minerals in broilers. This experiment was performed using 192 Ross 308 broilers in a completely randomized design with 4 treatments, 6 replications and 8 broilers per replication in a 42-day breeding period. Experimental treatments are: (1) base diet, (2) base diet + 50 mg/kg mixture of plant extracts, (3) base diet + 100 mg/kg mixture of plant extracts and (4) Base ration + 200 mg/kg mixture of plant extracts. Functional parameters of feed intake, weight gain and feed conversion ratio were measured at the end of 42 days of rearing. On the last day of the experiment, 3 chickens were selected from each replicate for blood sampling. Samples were transferred to the laboratory to measure the activity of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase; These parameters were measured by an autoanalyzer and commercial kits of Pars Azmoun Company. Also, the amount of calcium, phosphorus, magnesium and iron elements in the blood were measured by autoanalyzer by spectrophotometry (Biowave model S2100 made in England) by commercial kits of Biochemistry Company. Then the birds were slaughtered and after filling, separating the ventricular contents and separating the components, the relative weights of different parts of the gastrointestinal tract were calculated in terms of body weight, and the relative lengths of the duodenum, jejunum, ileum and cecum were measured (Daneshyar et al. 2012). Experimental data were statistically analyzed in a completely randomized design by SAS statistical software (2003) using GLM linear procedure. Mean comparisons were performed using Tukey-Kramer test at 5% level. The results showed that feed intake and feed conversion ratio were not affected by experimental treatments (P>0.05). However the treatments receiving 100 and 200 g/ton of mixed plant extracts had more body weight gain than the control treatment (P<0.05). Consumption of all three levels of plant extracts resulted in a significant increase in the length of jejunum and ileum of chickens (P<0.05). On the other hand, duodenum and cecum length were not affected by experimental treatments (P>0.05). There was no significant difference between the relative weights of the duodenum, jejunum, ileum and cecum between the experimental treatments (P>0.05). The results showed that the levels of liver enzymes aspartate, transaminase and alkaline phosphatase were not affected by experimental treatments (P>0.05). However, consumption of 100 and 200 g/ton of plant extracts reduced the amount of alanine aminotransferase and lactate dehydrogenase in comparison with the control treatment (P<0.05). The results showed that the consumption of a mixture of plant extracts had no significant effect on the amount of phosphorus and iron in the blood serum of broilers (P>0.05). On the other hand, consumption of 200 g/ton of mixed plant extracts compared with the control treatment increased the amount of calcium and magnesium in the blood of broilers (P<0.05). From this study, it is concluded that up to 150 g/t of a mixture of Cinnamomum verum, Origanum vulgare and Capsicum annuum extract in broiler diet without changing feed intake led to improved weight gain and increased relative length of ileum and jejunum in broilers. Liver enzymes were at normal levels and even showed a decreasing trend; The blood calcium and magnesium levels of broiler chickens also increased. Therefore, up to this level, a mixture of cinnamon, marjoram and pepper extract can be used in broiler diets.

The aim of this study was to determine the attractiveness of plants using by honey bee in the rangeland of Aliabad Mousiri, Koohrang, Chaharmahal and Bakhtiari province. For this purpose, plant species were collected during the growing season at a distance of 1500 meters from the location of bee keeping point in rangeland. The attractiveness of the plants used by bees, considering three criteria; Time, number of bees and distance and relying on indigenous knowledge and experience of beekeepers were determined. According to the results, species with attractiveness for bees include between 60 and 65% of plant composition, which plants with excellent, good, medium and low attractive plants respectively, constitute11.79, 44.94, 4.49 and 38.76, of the share of species in plant composition. The flowering period of most of the plants used by bees in the rangelands of the region is from the beginning of June to the end of August. Also 29 species producing nectar(16.29%), 40 species producing pollen (22.47%) and 110 species producing nectar and pollen(61.79%) were identified. The results can be used to determine the suitability of rangeland habitats in terms of beekeeping in multi-purpose rangeland designs.

The use of food additives in the diets of farm animals such as poultry has an important role in improving the level of their health, increasing the amount of their products and improving their products quality. Nowadays, feed additives prepared from microbial products and medicinal plants are among the common additives used in feeding of broiler chickens. These products don’t have any adverse effects on broiler health, and their use in the diet of broilers has been welcomed by consumers.This experiment was conducted to investigate the effects of antibiotic, symbiotic, pepermint powder and mixture of symbiotic and pepermint powder on performance, carcass traits and blood parameters of broilers.

In this experiment 240 Ross 308 broilers were used in 5 treatments, 4 replicates and 12 chicks in each replicate in two experiment period include: growth (11 to 24 days), and finish (25-42 days), in a completely rondomised design. Experimental diets included: 1) control group (without any additives), 2) antibiotic (100 ppm.kg diet), 3) symbiotic (0.5 and 0.25 g.kg diet in growth and finish periods), 4) pepermint powder (1% of diet), and 5) symbiotic (0.5 and 0.25 g.kg diet in growth and finish periods) + peppermint (1% of diet).

The results showed that in growth period, using of pepermint powder significantly reduced the amount of final weight (p<0.05). In finish period, all additives in contrast to control group, increased the amount of daily weight gain and improved feed conversion ratio (p<0.05). In totall experiment period, all additives increased the amount of daily weight gain (p<0.05). Experimental groups had no effects on the amount of daily feed intake. Experimental groups incontrast with control group, significantly reduced the amount of bours fabrisious relative weight (p<0.05). So, the the lowest relative weight blonged to peppermint treatment, whereas the highest it blonged to control group. Symbiotic + peppermint group significantly reduced the level of blood LDL (p<0.05).

Finally using of feed addtives in diets of broiler chicks such as current experiment recommended doses can be having benifical effects on their performance, immunity and blood parameters.

This study was performed to compare the effect of diets containing ethanolic extract of Echinophora platyloba at two levels of 0.3% and 0.5% and Phosphoflavomycin growth-promoting antibiotic (0.04%) on performance, immune response, and blood biochemical characteristics of broilers using 160 male day-old chicks in a completely randomized design manner using 4 experimental groups, 4 replications and 10 chicks in each experimental unit. The results indicate that in the fourth week of production, there was a significant increase in body weight of the treatment receiving Echinophora platyloba extract (0.3%) compared to other experimental groups (P≤0.05). On day 14th, in both groups fed with Echinophora platyloba extract (0.3 and 0.5%), a significant increase in feed conversion ratio was found when compared to the control and growth promoter antibiotic treatments (p≤0.05). The treatment fed with 0.3% Echinophora platyloba extract increased the percentage of carcass and spleen significantly (p≤0.05) when compared with other dietary treatments. No significant changes are found due to both levels of Echinophora platyloba extract on immune response and blood biochemical parameters of broilers. In contrast, the group fed with antibiotic significantly reduced the blood levels of LDL and ALP, when compared with control and 0.3% Echinophora platyloba groups (p≤0.05). In general, the application of Echinophora platyloba extract (0.3%) led to a significant improvement in performance and some carcass traits percentage of broilers and could be recommended as a suitable alternative to antibiotic growth promoters.

Nowadays, there is an increasing interest to use organic compounds in broiler chicken diets instead of antibiotics and other feed additives may cause deleterious effects on the poultry products consumers. Using medicinal plants have different effects on broiler life such as improving feed efficiency, augmentation of immunity, producing more desirable carcass and so on. The goal of this study was to investigate the effect of adding coneflower and thyme alcoholic extracts to diet on performance, carcass characteristics, internal organs weights and also some blood and immunity parameters of broiler chickens.

One hundred-sixty 1-d-old chickens (male and female) were randomly divided into four treatment groups with four replicates in each, and reared for 42 days. The treatments were: 1- control (basal diet formulated according to Cobb500 nutrients recommendation), 2- adding 0.2% thyme extract into basal diet, 3- adding 0.2% coneflower extract into basal diet, and 4- adding 0.2% of thyme+ 0.2% of coneflower extracts into the respective basal diets; starter (1-10 d), grower (11-23 d) and finisher (24-42 d) that were fed to the birds from the beginning. Experimental plants extracts were collected via UV-extraction method by ethanol followed by the rotary evaporation to eliminate the diluent. All the feeding and vaccination programs of chickens were in accordance with Cobb500 commercial strain recommendations. Feed intake, weight gain and feed conversion ratio of chickens were weekly recorded. At the end of the study, one bird of each replicate was slaughtered for carcass analysis and blood sampling. Blood parameters were assayed via  spectrophotometer. Carcass parts and internal organs weights were expressed as a percent of carcass weight. The antibody titers against Newcastle and
Influenza diseases were assayed. Data were analyzed as a completely randomized design and the means comparison was performed by least significant different test.

Results showed that the effect of treatments on the amounts of feed intake and weight gain of chickens over the study. Feed conversion ratio of chickens was significantly affected by the treatments where the lowest was observed in control group and the highest in coneflower group. Carcass traits (the weights of empty carcass, breast, thighs, abdominal fat and back) and internal organs weights (liver, heart, lungs, intestines and gizzard) were not affected by the treatments. The weights of body organs are basically affected by genetic potential that the used chickens were very close in this sight of view, and weight gain also among groups was not significantly different. Effect of treatments on antibody titers against Newcastle and influenza was significant. The lowest antibody titer against Newcastle and the highest against influenza were observed in thyme group. Both of coneflower and thyme were showed having stimulatory effect on antibody production in poultry, but the different effects observed in the present study may be due to the epidemic of
diseases and also the hygienic conditions of the farm. Adding coneflower and thyme into the diet increased the bursa of fabricius weight of chickens than the control, but it had no significant effects on spleen weight. It should be mentioned that the chickens in the present study were vaccinated according to the provider company recommendations and also a coccidiostat compound was used in the diet that they together can obstruct or interrupt on the expected beneficial effects of coneflower and thyme on immune parameters. Adding thyme and coneflower into the diet caused a marked decrease in blood lipids concentrations. One of the desired properties of medicinal plants is lowering the blood’s and carcass’s lipids that was observed in the present study. It is reported that these plants have some components suppressing the lipids synthesis in liver and also other ones effect on lipase enzymes activity in tissues. The treatments had no significant effects on the hematological parameters of chickens. Whereas there were no significant differences in the amount of daily feed intake and weight gain of chickens and also all of the environmental conditions for chicken were the same, therefore none of hematological parameters were affected by the treatments.

Generally, adding coneflower and thyme extracts into the diets of chickens had not significant effects on their growth performance in the overall period of the experiment and carcass traits as well. Using coneflower and thyme extracts in broilers diets has a booster effect on the antibody titer against influenza, while no positive effects were observed for Newcastle disease. Adding coneflower and thyme extracts into the diet of chickens prominently decreased the all types of blood lipids. No synergistic effects were observed between coneflower and thyme extracts wherever they had a significant effect on assayed parameters.

The object of this research was to identify the medicinal plants using by honey bee and determining their attractiveness in the rural rangelands of Chaharbagh, Golestan province. For this purpose, to investigate the honey bee behavior towards medicinal plants, 100 1m2 plots were laid out in the 1500 m around bee keeping point. The canopy cover of each plant was recorded and the species composition was calculated. Three criteria consisting of time, the number of bees and distance from bee keeping point were evaluated. Results showed that the most plant families using by honey bees were Asteraceae equal to 21.62%, Lamiaceae equal to 18.92% and Fabaceae equal to 16.22%. Five plant species of Thymus kotchyanus, Teucrium polium, Astragalus gossypinus, Verbascum phlomoides and Cichorium intybus L. were selected as the dominant medicinal plant species in the study area. The most numbers of bees were in the circle of 500 m from bee keeping point and in the morning the most of bees were using medicinal plants. For the total area, the most attractive plant species was Astragalus gossypinusand and then, Thymus kotchyanus, Verbascum phlomoides, Cichorium intybus L.and Teucrium polium were the attractive plants.

In the last decades a substantial increase have been done in the research and application of herbal supplements and essential oils as feed additives in ruminant nutrition. One of the main reasons for this trend is to substitute antibiotic growth promoters, which have been completely banned as feed additives in the European Union since 2006 because they are suspected of contributing substantially to increasing resistance among human pathogens. Recent investigations have shown significant antimicrobial effects of several essential oils and essential oil compounds. Also investigations about ruminant nutrition showed a great potential for medicinal plants to be included in daily rations as different plant parts, essential oils or extracts. For centuries, essential oils – defined as natural oils typically obtained by distillation and having the characteristic fragrance of the plant or other source from which they are extracted – have been used around the world for a variety of therapeutic purposes. The ancient Egyptian, Greek, Chinese and other cultures used essential oils in cosmetics, perfumes and medicines. Today, many people use essential oils to enhance their mental, emotional and physical well-being. Mohabadi dairy goats showed a great milking performance as well as high energetic efficiency of milk production. As we know essential oils or medicinal plant extracts have their own problems to ration inclusion such as higher price and lower durability compared with original plant materials. Additionally, powdered pant parts can be easily mixed with the prepared ration without concerns regarding volatility of the core materials. Thus, this experiment was carried out in order to study the effects of fennel seed powder (Foeniculul vulgare) supplementation with two types of diets (based on barley or corn) on performance, rumen fermentation and blood parameters in pre and post-partum Mohabadi dairy goats.
Material and Twenty-four Mohabadi dairy goats were used in a completely randomized factorial design (2×2) and received 4 experimental diets including 2 levels of the fennel seed powder (0 and 10 gr/DMI) and two types of cereal grains (corn and barley). Animals were selected based on the parity, previous milk yield, and body weight and parturition time and randomly assigned to the each of the treatments. Animals were in experiment 30 days before to 30 days after the parturition and keep individually. Effects of dietary treatments on daily weight change, milk yield and dry matter intake were assessed as repeated measures data. Also, the effects on milk composition and milk component yield, apparent total tract nutrient digestibility, ruminal fermentation parameters, ruminal volatile fatty acid profile and energy related plasma parameters ante- and post-partum periods were addressed.
The results of this study showed that fennel supplementation significantly increased dry matter intake and reduced body weight loss in early lactation (P˂0.05), but the grain type did not show a significant effect. Also, milk yield significantly increased and milk fat percentage decreased (P˂0.05) by the Fennel seed supplementation. Nevertheless, fennel seed supplementation did not change daily milk fat, protein, solids and solids nonfat production. Milk production efficiency as calculated based on milk yield per unit of dry matter intake, increased with fennel seed supplementation, may be due to estrogenic and prolactin enhancing effects of the fennel seeds Indeed, the experimental treatments could not significantly change the nutrient digestibility, total VFA concentration and pH. However, the ruminal VFA profile significantly affected by the fennel seed powder. Acetate concentration decreased and butyrate and propionate molar proportions increased with Fennel seed supplementation (P˂0.05). Dietary grain type could not exert a significant effect in ruminal fermentation parameters. Fennel seed powder significantly decreased the ammonia nitrogen concentration and protozoa population. In post-partum period, fennel seed powder supplementation significantly increased blood glucose concentration and decreased plasma urea, BHBA and NEFA (P˂0.05).
The results of the present experiment in line with the cited previous researches showed that the fennel seed powder supplementation in the dairy goats diet can improve the production performance and efficiency of early lactating dairy goats. Lowered negative energy balance in early lactating animals, was a result of fennel seed powder supplementation. Based on the present experiment it can concluded that fennel seed powder supplement with corn or barley based diets can improve production efficiency and metabolic profile of ante- and post-partum dairy goats.

This study evaluated the efficacy of aqueous extract of Thymus daenensis to ameliorate the adverse effects of aflatoxin B1 (AFB1) in Japanese quail. The experiment was conducted as a 2×2 factorial arrangement in a completely randomized design with two levels of aflatoxin (0 and 500µg/kg) and two levels of aqueous extract of T. daenensis (0 and 2000 mg/kg). Each of the 4 dietary treatments was fed to five replicate cages (4 birds/cage) from 24 to 45 days of age. The results showed that Aflatoxin and extract did not have any effect on the histo-morphology of jejunum of birds (P

A study was conducted to evaluate the effects of three medicinal plants, antibiotic and probiotic on performance, carcass traits, immune system and biochemical parameters in broiler chicks. A total of 360 one-day old mixed Ross-308 broiler chicks were assigned to six treatment with 3 replicate (n=20). The diets were fed including: the control (without feed additive), control supplemented with 20 ppm of virginamycin, control supplemented with 50 ppm of probiotic (protexin), control with 1.5% of either Thyme (thymus vulgaris L), Chicory (cichorium intybus), Pennyroyal (mentha pulegium). Body weight gain increased with antibiotic supplementation and decreased with adding Pennyroyal (P

The purpose of this research was to study the addition of cinnamon powder in diet, on productive performance, blood metabolites and inner organs weight of broiler chickens. Therefore, an experiment was carried out with two hundred and twenty five male broiler chicks Ross 308 in form of a completely randomized design with 5 treatments and three replicates during 42 days. Treatments were involving: 1- control group (basal diet without any additive), 2- basal diet plus 0.1 % cinnamon powder, 3- basal diet plus 0.2 % cinnamon powder, 4- basal diet plus 0.3 % cinnamon powder, 5- basal diet plus 0.5 % cinnamon powder. The results of this research showed that cinnamon powder has no significant effect on the blood cholesterol, triglyceride and caecum levels plus percentage of pancreas weight (P>0.05). Whereas, addition of cinnamon powder induced significant effects on the glucose, LDL, AST, ALT, TBA and some of the inner organs weight percent such as liver and abdominal fat (P

This experiment was conducted to evaluate the effects of different levels of medicinal plant blend (pennyroyal، nettle and chicory) with and without enzyme (Safizym GP 800) on performance، egg quality and blood biochemical parameters of laying hens. The experiment was carried out as a factorial (3×2) (0، 0. 75% [0. 25% from each plant]، 1. 5% pennyroyal، nettle and chicory [0. 5% from each plant]،) and (0، 0. 05% enzyme) in a completely randomized design (CRD) with 216 Hi-line (W36) laying hens in six treatments and three replicates (with twelve hens in each replicate) for a period of 12 weeks during weeks 25-37 of hen ages. Results revealed that the use of different levels of medicinal plant blend، enzyme and interaction between them had significant effects on performance، egg traits and blood biochemical parameters of laying hens (P<0. 05). The highest egg production was obtained by using 0. 75% medicinal plants blend. The highest amounts of egg specific gravity، blood triglyceride and total protein were obtained by using 1. 5% medicinal plants blend. Using 0. 05% enzyme significantly improved the performance of laying hens. Regarding interaction effects، the highest performance was found when using the highest egg production percent، highest egg mass and the highest amount of feed 0. 75% medicinal plants blend × 0. 05% enzyme. The overall results indicated that using 0. 75% of medicinal plants (pennyroyal، nettle and chicory) blend with 0. 05% enzyme supplementation (Safizym GP 800) could improve the production parameters of laying hens.

This experiment was conducted to evaluate the effects using different mixtures of Nettle, Pennyroyal and Zizaphora medicinal plants on performance, carcass quality, biochemical and immunity parameters of broilers. This experiment was conducted in a completely randomized design with 240 of Ross-308 strain broiler in 4 treatments and 3 replicates (with 20 bird in each replicate) from 1 to 42 days and included: 1) control group no medicinal plants, 2) 1% Nettle and 0.5% of each others medicinal plants, 3) 1% of Pennyoyal and 0.5% of each others medicinal plants and 4) 1% of Zizaphora and 0.5% of each others medicinal plants. The results showed that using different mixtures of Nettle, Pennyroyal and Zizaphora medicinal plants have significantly effects on performance and carcass traits of broilers (P<0.05). The highest amount of daily weight gain (46.32g), the highest percents of carcass and breast (72.72%) and (33.67%) and the lowest percent of abdominal fat (3.4%) were observed in 3 experimental group. The overall results showed that the using of medicinal plants mixtures like 3 experimental group, has positive effects on performance and carcasses traits of broilers.
