EFFECT OF PROCESSED ABATTOIR WASTE (BOVINE BLOOD RUMEN DIGESTA MIXTURE) AS PARTIAL REPLACEMENT FOR SOYABEANS ON PERFORMANCE OF BROILER CHICKENS

Abstract

A total of 288-day-old chicks were used to investigate the effect of processed bovine blood rumen digesta mixture (BBRDM) as partial replacement for soyabeans on performance of broiler chickens. Considerable quantities of fresh bovine blood and rumen digesta were collected on weight/weight basis using the 1:2 ratio, processed via heat treatment for 2 hours 30 minutes and thereafter sun-dried for five days until it was dried. The BBRDM was used to formulate four dietary treatments consisting of 0 %, 20 %, 40 % and 60 % as partial replacement for soyabeans. The experimental birds were balanced for weight and divided into four (4) treatment groups of seventy-two (72) birds each. Each group was further divided into 4 subgroups comprising of 18 birds each serving as replicate. Data collected on the response variables (growth performance indices, haematological parameters and carcass traits) were subjected to One-way Analysis of Variance. Results revealed non-significant variations in all the growth, haematological indices (at starter and finishing phases) as well as carcass traits measured. In conclusion, partial substitution of soya beans meal with 60 % BBRDM in the diet is recommended for broiler chicken production for enhanced growth, better blood function, health status as well as carcass yield with probable reduction in the production cost.
