Effect of Graded Levels of Slaughter House Residues on Growth Performance and Haematological Parameters in Broiler Chicken’s Ration

Abstract

This study was aimed to investigate the effect of graded levels of slaughterhouse residue (SHR) on performance and haematological parameters of broiler chickens over the period of 35 days. One hundred day-old chicks were fed diets containing SHR at 0 (control), 5, 10 and 15% dietary levels represented as T1, T2, T3 and T4, respectively. Diets were fed to experimental birds in a completely randomized design (CRD). Each treatment was replicated five times consisting 5 birds per replicate (25 chicks/ treatment). The control diet was a commercial feed in the experiment. The parameters of performance considered were weight gain, feed intake, feed conversion ratio (FCR), dressing percentage, weight of breast, thigh, wing and abdominal fat. Similarly, the parameters of haematology were haemoglobin (Hb), packed cell volume (PCV) and erythrocyte sedimentation rate (ESR). Heart, liver, spleen, proventriculus and gizzard weights were also measured and recorded. The final body weights of broiler chickens fed T1, T2, T3 and T4 were found 1732.20 g, 1731.12 g, 1776.20 g and 1930.80 g, respectively. The total feed intake of treatment groups (T1, T2, T3 and T4) were 2711.64 g, 2707.94 g, 2720.89 g and 2751.18 g, respectively. The FCR was predicted by calculation for T1, T2, T3 and T4 (1.57, 1.56, 1.53 and 1.43 respectively). On the other hand blood parameters (Hb, PCV and ESR) were found statistically similar. It is concluded that the use of SHR as an alternative source of protein can be included in the diet of broiler chicken up to 15% dietary level as it might enhance the overall performance of broiler chickens without any adverse effect on growth with some reduction in the cost of production.
