Quality traits of eggs in birds fed diets containing different energy and protein levels with and without fish meal

Abstract

The present study was carried out to evaluate quality traits of eggs in birds fed diets containing different energy and protein levels with and without fish meal. Eighty birds 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 riice polish (DORP). In the present study egg shell thickness was not significantly influenced by the levels of dietary energy and protein. However this research indicated that reduction of protein from 16.5 to 14.5 per cent caused significant (p
