Effects of the ratio of dietary fish meal to soybean meal on the performance of broiler chicks

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler
chicks which were randomly assigned to four treatment groups with five replicates into 20 pens
and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler
chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30%
soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1:
15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler
chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6%
fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27%
soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly
performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean
meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler
chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious
that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower
feed efficiency of this diet should be considered in economical point of view.
