原始语种摘要: Different sources of Zinc (Zn) were compared to assess their possible effects on performance, nutrients retention, mineral distribution and some serum parameters of broiler chickens. A total of 200 one-day old Ross 308 chicks were divided into in equal four dietary treatments groups with five replicates each of ten chicks. The experimental groups were given the basal diet (inorganic ZnO), basal diet supplemented with organic Zn (Zn methionine), nano-ZnO and Znmix (organic Zn and nano-ZnO) at a concentration of 50 mg/kg of diet. After 42 days of feeding trial, the group supplemented with nano-ZnO exhibited the best final body weight and feed conversion ratio (2380 g/bird and 1.69, respectively). Nano-ZnO and Zn-mix supplementation significantly increased crude fat retention (86.70 and...
