Abstract:
The effects of feeding different levels of ox bile salt (OBS) supplements on broiler performance, digestibility of crud fat and some blood chemical (cholesterol, triglyceride, high density lipoprotein and low density lipoprotein) were investigated. Three hundred and seventy five, day-old broilers chickens were assessed using a completely randomized design. Five diets, containing different levels of OBS (۰.۰۰, ۰.۱۵%, ۰.۳۰%, ۰.۴۵%, and ۰.۶۰%) were randomly assigned to ۵ replicates each of ۱۵ birds for a ۴۲-d period (۷d for adaptation and ۳۵ d for data collection). Feed intake, growth weight, crud fat digestibility and blood metabolites were determined. Supplementation of OBS levels in the diet of the broiler chickens improved (P < ۰.۰۵) body gain weight, feed conversion rate and crude fat digestibility. OBS had no effects (P > ۰.۰۵) on the feed intake. Feeding OBS-containing diets caused (P < ۰.۰۵) an increase of content of serum total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) and serum total triglycerides (TG). The animal performance reached its greatest value with simultaneous feeding of ۰.۴۵% and ۰۶۰% OBS. It has been concluded that the dietary supplementation of OBS had positive effects on body gain weight, feed conversion rate, crude fat digestibility, and serum TC, TG, HDL and LDL. Synchronized feeding of the great levels of OBS and fat digestibility (as an energy source) increased utilization efficiency of these byproducts in the performance of broiler chickens.The effects of feeding different levels of ox bile salt (OBS) supplements on broiler performance, digestibility of crud fat and some blood chemical (cholesterol, triglyceride, high density lipoprotein and low density lipoprotein) were investigated.
