In this study, the effect of different levels of selenium nanoparticles was investigated on sperm fluid enzymes including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), superoxide dismutase (SOD), catalase, lysozyme, malondialdehyde (MDA) and albumin in male breeders of rainbow trout. A number of 84 three-year-old male breeding fish were divided into four experimental groups with three replications. Fish were fed with diets containing 0 (control), 0.5, 1 and 2 mg of selenium nanoparticles per kg of diet for 60 days. The results of the analysis of the sperm fluid in different treatments did not show any significant difference in the amount of ALP, ALT and lysozyme in the sperm fluid (P>0.05). The highest amount of ALT enzyme was in the treatment of 2mg of selenium nanoparticles, and the amount of MDA, ALT and ALP of sperm fluid in other treatments was significantly higher than the control treatment (P<0.05). Based on the obtained results, in order to increase the reproductive efficiency of rainbow trout males and improve the antioxidant indices and immunity of sperm fluid, it is recommended to add 2mg of selenium nanoparticles per kg to the diet.

The present experiment was performed on the effect of Eryngium caucasicum and vitamin C on performance, carcass characteristics, blood parameters and immune system in broilers. The experiment was performed with 4 treatments, 5 replications and 15 one-day-old Ross 308 chickens in each replication in a completely randomized design. Treatments include 1) control (diet without additives), 2) control + 2% Zolang plant, 3) control + 0.2% vitamin C, 4) control + 2% Zolang plant + 0.2% of vitamin C. The results showed that feed intake, weight gain and broiler conversion ratio in the final periods as well as the whole period in treatments that used a mixture of Zolang plant and vitamin C, had a significant increase with the control (p <0.05). The percentage of carcasses in the treatments that used a mixture of Zolang and vitamin C was significantly increased with the control (p <0.05). All experimental diets significantly reduced the total blood protein of broilers compared to the control (p <0.05). The mixed diet of Zolang plant and vitamin C caused a significant increase in HDL compared to the control (p <0.05). The results showed that the effect of experimental treatments was significant only on alkaline phosphatase (p <0.05). Also, bursa fabricius weight in treatments that used a mixture of Zolang plant and vitamin C had a significant increase with the control (p <0.05). In general, the results showed that the use of a mixture of Zolang and vitamin C in the diet of broiler chickens can improve performance and strengthen the immune system.

Many modern medicines are obtained from medicinal plants, and the properties of many of these plants have been confirmed and proven with new investigations. The purpose of this study is to investigate the effect of different doses of hydroalcoholic extract of Ferulago angulata on biochemical and hematological parameters orally on male Wistar rats. 28 heads of male Wistar rats that were randomly studied experimentally. Mice were divided into a control group without extract and groups receiving Ferulago angulata extract with doses of 50, 150 and 300 mg/kg. The treatment groups were conducted for 16 weeks. After the end of the test, serum glucose level, lipid profile including triglyceride, cholesterol, LDL, HDL, albumin, total protein and liver enzymes ALP, AST and ALT were measured. Different doses of Ferulago angulata extract changed the levels of some lipid factors and liver enzymes in the studied groups compared to the control group. Different doses of Ferulago angulata extract caused a significant decrease in the level of glucose, triglycerides and liver enzymes (AST and ALT), and the level of LDL. Also, the amount of albumin, HDL and total protein increased, and there was no change in the amount of cholesterol and ALP. The results of this study showed that Ferulago angulata plant has positive effects on some biochemical factors and liver function improvement despite its antioxidant compounds. Therefore, we can introduce Ferulago angulata plant as one of the most effective plants in the medicinal plant industry and treatment, control and prevention of many diseases.

The cement production activities leads to the release of different pollutants into the environment. This research was conducted to study the effects of dust particles released by Behbahan cement factory on the absorption of some nutrient elements and biochemical parameters in dominant herbaceous species grown in this area, including Bromus tectorum, Malva neglecta and Sinapis arvensis. Plant samples were transferred to the laboratory. Then, the concentrations of some nutrient elements, such as Fe, Cu, Zn, K, Mn, P and N, were assayed in plant and soil samples. Moreover, some biochemical parameters, such as photosynthetic pigments, total protein, soluble carbohydrates, proline, relative water content, leaf pH total ascorbate and air pollution tolerance indexes (APTI), were evaluated. Based on these results, it is supposed that three plant species are tolerant to air pollution with an APTI higher than 16. In addition, it seems that the dust released by the cement factory has not led to a toxic accumulation of the elements in the studied plants. The deficiency of Mn and P was determined for three plant species. On the basis of biochemical analysis, it is supposed that these plant species possibly use different strategies to tolerate the pollutants in this area.

In the present study, the water soluble polysaccharide extract of Padina australis (PPE) was added in concentrations of 0, 0.5, 1 and 1.5 g/kg to the diet of white leg shrimps (Litopenaeus vannamei) with average weight of 1±0.1 g to assess its ability to improve the activity of digestive enzymes and the biochemical parameters. Following feeding on these diets for 60 days, the highest activity of lipase and protease was shown in treatment containing 1.5 g PPE/kg diet (p < 0.05). The levels of albumin and total protein were higher in treatments containing various levels of PPE compared to the control treatment (p < 0.05). The lowest levels of GLU, TRI, CHO, ASP.ALT and ALP were observed in the treatment containing 1.5 g PPE/kg diet indicating significant difference with other treatments (p < 0.05). The results demonstrated that inclusion of 1.5 g/kg diet of PPE in commercial feeds might enhance the digestion function, liver health and nonspecific immunity system of L. vannamei.

In the current study, the effects of different levels of probiotics, Lactobacillus plantarum in the diet of Asian sea bass, Lates calcarifer on body composition, serum biochemical parameters (glucose, cholesterol, triglyceride and albumin) and liver enzymes (lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase) were investigated. This experiment was carried out with three treatments and a control group for a period of four weeks. The treatments were included 0, 1×106, 2×106, 3×106 colony forming unit (CFU) gram probiotic in each gram of basic diet. Fish with an average weight of 50.26 ±0.89 grams were randomly distributed in tanks and in each tank stocked 20 pieces of fish. Feeding was done twice a day. The obtained results indicated that the use of different levels of probiotic in diet of Asian sea bass had no significant effects on serum biochemical parameters and liver enzymes. The different levels of probiotic did not affect protein, ash and moisture values between the treatments and the control group (P> 0.05). Moreover, fat value in the fish T2 and T3 was significantly higher (P< 0.05) than the fish control and T1. Also, nitrogen free extract (NFE) value varied significantly (P < 0/05) between the control and the fish T3. Overall, this study indicated that this probiotic had no significant effect on some blood biochemical parameters and liver enzyme, but at the high level can positively influence on body composition of Asian sea bass.

In this study، semen spermatological and biochemical parameters in wild and cultured common carp were investigated. Na+ (Mmol/l) and K+ (Mmol/l) ions were measured by flamephotometere and Ca2+ (mg/dl)، Mg2+ (mg/dl)، blood serum organic composition such as glucose (mg/dl)، cholesterol (mg/dl) and total protein (g/dl) were measured by spectrophotometere. Duration of sperm motility was measured by stereomicroscope and spermatocrite was measured by micro centrifuge. The results of this study suggested that there were a highly significant difference of Ca2+، Cl-، Na+، K+، total protein، cholesterol، glucose، and pH (P<0. 05) levels between wild and cultured carp but there was no significant difference in seminal plasma Mg2+ (P>0. 05). Also، there were significant differences of spermatological parameters (value of sperm، spermatocrite، sperm density، motility duration and percentage of motile spermatozoa) between wild and cultured common carp (P<0. 05) so that in cultured carp were more than wild carp. This study showed، that sperm quality of cultured carp is better than that of wild carp.
