چکیده انگلیسی
In the course of the trial a positive influence was observed by supplementation of YD. On day 35 body weight (BW) (1520Â g) and daily weight gain (42.37Â g/day) were greater in birds receiving 1Â kg/t of YD compared to the control (1374Â g BW, 38.18Â g/day, respectively; PÂ =Â 0.05). Supplementation with 2Â kg/t of YD did not improve 35Â day BW but did improve cumulative feed-to-gain ratio by 13% (PÂ <Â 0.05) versus birds fed the control diet. Histological evaluation demonstrated greater goblet cell density in birds fed either concentration of YD (PÂ <Â 0.05). Villus height and crypt depth, however, were unaffected. Apoptotic enterocytes were decreased by both concentrations of YD (PÂ =Â 0.02). Supplementation of YD had no effect on blood cell counts (PÂ >Â 0.05). The inclusion of YD in diets of broilers was able to improve broiler performance, intestinal goblet cell numbers and to reduce numbers of enterocytes undergoing apoptosis.
