Abstract

"A total of two hundred and forty 24 weeks old Golden Nestlink point of lay birds were used in a 52 weeks study to investigate the economics of supplementing layers ration with dietary levels of vitamins C and E as a means of adapting the birds to heat stress resulting from changing climatic variables. The birds were randomly assigned to any of the sixteen treatments emerging from a combination of four doses of vitamin C [0, 200, 400 and 600mg /kg] and four doses of vitamin E [0, 125, 200, and 375 mg /kg] in a 16% Crude Protein ration for layers. The experimental design was a 4 X 4 factorial with sixteen treatment combination in a completely randomized design. Results showed that there was a significant improvement in all the economic indices [total egg production, egg weight, feed cost per dozen eggs and egg revenue] in the supplemented groups. Economic indices of birds on 400 mg vitamin C + 125mg vitamin E were significantly (P<0.05) higher. The unsupplemented group recorded the least value of all economic indices. It is concluded that a combination of 400 mg vitamin C + 125 mg vitamin E per kg of layers ration will help heat stressed layers in Nigeria perform economically better in the face of emerging climatic changes."
