Effect of different energy and protein levels on the egg production of rural poultry
2003
Rehman, A. | Bhatti, B.M. (Poultry Research Inst., Rawalpindi (Pakistan))
A study was conducted to determine the effect of different nutrients i.e. metabolizable energy (ME) and crude protein (CP) content of ration on the egg production and egg weight of rural layers. For the purpose six different experimental rations containing 2700, 2900 kcal/kg ME and 14, 16, 18 percent CP were offered to the birds. The results indicated that egg number increased with proportional adversely affected as the CP of the ration was increased weight of the layers was proportionally increased with ration at constant ME level, while increase in ME level egg weight. increase in ME, while it was at constant ME level. The egg increase in CP content of the did not significantly affect the egg weight.

Cinar, M. | Nizamlioglu, M.(Selcuk Univ., Faculty of Veterinary Medicine, Konya (Turkey))
In the present study, effects of different doses of dietary Cu and Zn suplementation on plasma biochemical parameters in broilers were investigated. In this study, a total of 430 avian broiler chicks were used and divided into 12 groups as control and treatment groups in which different doses of Cu, Zn and Cu+Zn supplemented
