Haematology and Serum Biochemistry of Pullet Chicks Fed Diets with Low Energy and Crude Protein Contents with Enzyme as Additive
Abstract
This study was carried out to investigate the haematological and serum biochemical response of pullet chicks (Isa Brown) fed low energy and crude protein diets with enzyme as additive. The study was conducted from day old to 8 weeks of age with combined dietary levels of 2800, 2600 and, 2400 kcal/kg of energy and 20, 17and, 15% of crude protein (CP). The pullet chicks were assigned to 9 treatments of 60 birds per group, in four replications of 15 birds per replicate, in a 3×3 factorial in a completely randomized design (CRD). Results showed that haemoglobin concentration, packed cell volume, total white blood cell count, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, lymphocytes, and heterophils were significantly (p<0.05) affected by dietary interaction (energy×protein) levels. Urea, creatinine, Na+, Cl-, HCO3-, and K+, parameters for pullet chick kidney function test were found to increase significantly (p<0.05) across interaction levels from 2800kcal/kg×20% CP to 2400kcal/kg×15% CP. Values for total protein, globulin, aspartate aminotransferase, alanine transferase, alanine phosphatase, bilirubin and glucose were found to decrease significantly (p<0.05) across treatments from 2800kcal/kg×20% CP to 2400kcal/kg×15% CP. Lipid profile tests were found to be significantly (p<0.05) different among dietary treatments. The results of haematological and serum biochemical parameters for pullet chicks showed no detrimental health challenge across dietary treatments for birds fed low-energy and low-crude protein diets.
