This experiment was conducted to investigate the effects of different levels of Garlic extract on performance )including daily body gain, feed consumption and FCR and some carcass parameters(including hot carcass weight, heart, liver, lungs, kidneys, fad around of kidneys, empty the digestive system, thigh, shoulder) and blood parameters((including Glucose, Cholesterol, Triglycerides, HDL and LDL) of fattening Zel lambs. Essential oils and extracts are relatively new compounds that are used as supplements in animal feed.
In the 14 week experiment (2 weeks adaptation and 12 weeks for main experiment period), 12 lambs were allocated in 3 treatments respectively 0, 125 and 250 ml (of garlic extracts that sprayed on daily feed) of 4 lambs each. All of lambs weighted 2 weeks once at the experiment period. Then data were analyzed with the GLM procedure of SAS and mean of parameters was compared with Duncan’s at P The results showed that in performance parameters daily weight gain was 128, 137 and 146 gr/day, mean of daily feed intake 1.77, 1.83 and 1.87 Kg and feed conversion rate was 15.5, 14.9 and 13.10 in treatments 1, 2 and 3respectively. There was significant difference in daily weight gain between experimental treatments, but the amount of daily feed intake and FCR did not showed significant different. At the end of experiment period, 9 lambs were slaughtered and their carcasses were evaluated. It showed that in carcasses parameters such as mean weight of carcass, heart, liver, 4 compartment stomach, arms, thigh and thigh to carcass ratio had significantly increased but abdominal fat had significantly decrease with increasing use of Garlic extract .In blood parameters of Triglyceride , Glucose, Cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) levels had significant different. However Cholesterol, HDL and TG was decreased and amount of HDL and Glucose increased.
The results showed that performance parameters and carcass parameters in fatting lambs improved with garlic extract and reduced fat and increased daily weight gain. Also a significant reduction in Cholesterol, LDL and Triglyceride in treatments containing Garlic extract showed that the addition of Garlic extract to the diet was 250 Ml daily.

This study investigates the effects of garlic extract on salinity and PH stress resistance of white leg shrimp post larvae (0.1±0.01 g). The experiment was carried out on the basis of completely random model with 5 dietary treatments which include 0 (control treatment), 1cc (treatment 1), 2cc (treatment 2), 4cc (treatment 3) and 8cc (treatment 4) per 100g food in triplicate. 1500 shrimps were randomly stocked in 15 tanks (100 shrimps in each tank). Shrimps were fed 4 times a day for 7 weeks. At the end of this period, growth and nutritional indices were measured. Salinity and PH stress experiment was done. The results showed that use of 4cc and 8cc of garlic extract for each 100 gr in White leg shrimp’s post larvae improve growth indices of shrimps with regard to control treatment. Results showed that mortality started in 70 and 80ppt salinity, treatment 2 showed significant difference with control, and treatments 3 and 4 had significant difference with control and treatments 1 and 2. In 90ppt salinity treatments 2, 3 and 4 showed significant difference with control treatment. In PH stress, at pH 9 and 10 significant difference was not observed among treatments but in PH 10.5 significant difference showed between treatment 2 and control and treatments 3 and 4 with control and treatment 1. The results show that the economy could be due to diets containing garlic extract 4cc making diets for shrimp larvae posts be considered.
