Abstract :

Modern quail breeds and varieties show differentiated nutritional requirements. Particularly the
amount of protein consumed, as well as dietary energy to protein ratio determine the production
results. The present study was aimed at determining the effect of isoenergetic diets differing in
crude protein (CP) content, on the performance of Pharaoh quails. Three groups of birds (I, II and
III) were fed with feed mixes containing 21, 19 and 17% CP, respectively. During 23 weeks their
laying performance, egg weight, mortality rate, feed consumption and body weight were recorded
and egg quality assessed. The dietary CP level did not affect the final body weight of birds significantly, and mortality was similar in all groups. In group III (17% CP of the diet) laying performance was significantly lower than in group I and II, while no differences were found in egg weight and quality. Feed conversion ratio (kg feed per kg eggs laid) was lowest in group III.
