Abstract

The use of yeast in feeding capons was investigated. An Investigation was carried out on 40 capons of the hybrid line Ross 308, caponized at 28 days. For 22 weeks the capons were given feed and water ad libitum and kept in controlled zoo-hygienic conditions. The experimental capons obtained yeast in feed mixtures as protein feed, while the control capons were given commercial feed mixtures for fattening chickens with fish meal in the starter and oil grits in finisher 1 and finisher 2. The results of the study showed no statistically significant differences (P<0.05) between the final body weights of the capons, feed conversion, growth performance and share of breast weight in the carcass weight, which supports the conclusion that fish meal proteins can be successfully substituted with yeast proteins for feeding capons.
