Economics of egg production in birds fed on diets containing different energy and protein levels with and without fish meal

The present study was carried out to evaluate economics of egg production in birds (n= 80) fed on diets containing different energy and protein levels with and without fish meal divided into eight equal groups (T₁, T₂, T₃, T₄, T₅, T₆, T₇ and T₈). Birds in all the eight groups were fed maize, soybean meal, fish meal (Jawla fish) and deoiled rice polish (DORP). The economics of egg production was calculated on the basis of quantity of feed consumed, its cost and price of eggs. Cost of feed consumed daily per dozen eggs as well as per kilogram eggs was calculated. Considering the receipt per dozen eggs as well as per kg eggs and the cost of feed consumed and finally the return over feed cost was calculated based on the per dozen as well as per kg eggs. Based on the net return over feed cost per dozen as well as per kg eggs it was concluded that diet containing 14 per cent crude protein and 2700 kcal ME/kg was most economical. Hence considering the performance of the birds and economics of their egg production it was concluded that diet containing 14 per cent crude protein and 2700 kcal ME/kg along with lysine and methionine either through pure amino acids or fish meal was most economical.
