Abstract

A study was conducted to ascertain the effect of combining fish meal (FM) with blood meal
(BM) on live weight, carcass yield, internal organs and economic performance of broiler
chickens. 180 unsexed Anak day old chicks were used. There were four dietary treatments (T) of
45 birds each. Each treatment was replicated thrice each having 15 birds. The starter diets were
formulated in such a way that T1 served as control diet and contained 3.0% FM, T2 contained
2% FM + 1% BM. T3 contained 1% FM + 2% BM while T4 had 3% blood meal. For finisher
diets, T1 contained 2% FM, T2 = 1.50% FM + 0.50% BM, T3 = 0.50% FM + 1.50% BM and T4
= 2.0% BM. The birds were both fed the diets and water was given ad libitum. The experiment
was arranged in a completely randomized design (CRD. The experiment lasted for eight weeks;
four weeks for each phase. Combination of BM and FM at the starter phase improved growth
compared to 3% BM. Feed: gain ratio (FGR) and protein efficiency ratio (PER) were
significantly (P<0.05) better when FM was combined with BM. Total feed intake was
significantly (P<0.05) reduced during the starter phase by 3% BM. At the finisher phase,
combining 0.50% FM with 1.50% BM gave higher live weight, better FGR and PER than 2%
FM and 2% BM. The feed intake, carcass yield and internal organs were not affected
significantly (P>0.05). The gross margin of 0.50% FM plus 1.50% BM was better compared to
2% FM and 2% BM. In conclusion, addition of 1% FM and 2% BM in diets for starter broilers
and 0.50% FM and 1.50% BM in diets for finisher broilers is recommended.
