Abstract:

In the current study, a total of 300 male broiler chickens (Ross 308) were obtained from a commercial hatchery and fed diets with different levels of zinc oxide nanoparticles (ZO-NPs) during the starter phase (from 1 to 21 d). Experiential diets were including: T1 (control; basal diet), T2, T3, T4 and T5, were supplementation basal diet with 30, 60, 90 or 120 mg of ZO-NPs/ kg diet respectively. On d 21, four birds (one bird per replicate) as randomly selected, slaughtered and then carcass yield, breast and thigh composition were evaluated. The results indicated that breast and thigh muscle weight were higher in birds fed ZO- NPs compared to other treatment (P<0.05). As well as, dry matter, crude protein, calcium and phosphorous of breast and thigh muscles in T3 and T4 birds treatment were higher than control groups (P<0.05). As well, height and width of villi, crypts depth and VH/CD ratio broiler jejunum had significantly increased (P<0.05) in birds that fed diet supplemented with 60 and/or 90 mg of ZO-NPs.kg in comparison with control treatment. In conclusion, results of current study indicated that ZO-NPs improved carcass traits and quality of edible carcass of broilers, i.e., breast and thigh muscles, the mention improvement observed in broilers that fed basal diet inclusion of 60 to 90 mg of ZO-NPs/kg
