Growth response, hematology and serum biochemistry of finisher broilers fed blended bovine blood plasma and soya bean hull as replacement for fish and soyabean meal

Abstract

A 28-day feeding trial was conducted to investigate the growth response, hematology and serum biochemistry of finisher broiler chickens fed blended bovine blood plasma (BBP) and soyabean hull (SBH) mix. Four diets containing 0, 50, 75% and 100% mixture of bovine blood plasma and soya bean hull (BBP/SBH) coded T₁, T₂, T₃ and T₄ respectively were fed to 120 Anak broiler finisher birds. The birds were divided into 4 groups of 30 broilers per treatment replicated 3 times with 10 birds per replicate. The treatment diets were randomly assigned to the birds in a Completely Randomized Design (CRD). Performance data showed that the test ingredient significantly affected the daily feed intake, feed conversion ratio and daily weight gain of broiler birds. The results showed that hematological values like the Hemoglobin (Hb), Packed cell volume (PCV), Red blood cells (RBC) and white blood cells (WBC) decreased significantly (P<0.05) as the levels of BBP/SBH in the diets increases while the mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and clotting time increased proportionally. Serum biochemical parameters like Creatinine and Glucose increased as dietary BBP/SBH mixture increased in the treatment diets. Based on the above result, treatment 3(75%) mixture of BBP/SBH) is recommended to livestock farmers for optimum meat production and for profit maximization.
