The Effects of Probiotics and Food Restriction on Relative Growth and Serum Cholesterol and Triglycrides Contents in Broiler Chickens

This study has investigated the effects of addition of probiotic supplements to two types of food restriction programs on ascites, RV/ TV ratio and relative growth of heart also has determined the effects of probitic on total cholesterol and triglycerides concentrations in the blood serum. The first treatment accessed food freely. The second one had a skip-a-day restriction. In the third treatment, there was probiotic added to the second treatment. The fourth one, included bellyful feeding and the fifth one was the bellyful feed with probiotic supplement. Total cholesterol (Choi) and triglyceride (TG) were measured in blood samples of day 45. Results revealed that relative growth of heart reduces as the age increases. As the age goes up, the RV/ TV ratio raises as well and in case of food restriction diets, bellyful feeding may decrease the mortality caused by ascites. It should be noted that adding probiotic in the restriction period, reduced the ascites and overall casualties (P<0.05). The amount of total Choi and TG in the serum did showed a significant decline (P<0.01) in all dietary groups with probiotc.
