Sažetak
The aim of this study was to evaluate the possibilities of soybean meal and sunflower meal as plant protein alternatives to fish meal in broiler feed mixtures. The experiment was conducted on 180 one-day-old broiler chickens (Ross 308) divided into one control (C) and two experimental groups (E-1 and E-2). Chickens in the control group (C) were fed feed mixtures which contained fish meal, as opposed to experimental mixtures containing only soybean meal in starter mixture for both experimental groups, and sunflower meal (E-1) or soybean meal (E-2) as the only source of protein in finisher mixtures. Throughout the 42-day period of fattening, chicks were housed in cages in controlled environmental conditions and fed ad libitum. Effects on production results were evaluated by live weight, live weight gain, feed efficiency, mortality rate and carcass quality. Recorded values showed that the control group of chickens achieved higher live weight gain and lower feed efficiency compared to the experimental groups. The difference was statistically significant only in correlation with E-1 group (P<0.01). Carcass yield performance produced better results in both experimental groups, but with no statistical significance (P>0.01).
