Effect of bypass methionine-lysine supplementation on haematological and blood biochemical parameters of Jaffarabadi heifers

Abstract

Aim: The objective of an experiment was conducted to evaluate the effect of feeding bypass Methonine-Lysine on hematological and biochemical parameters on growing Jaffrabadi heifers of age from 12 to 18 month. Material and Methods: Eighteen Jaffrabadi heifers were divided into three groups of equal number: control group (T1 ), cotton seed cake (CSC) (T2 ) and bypass Methionine-Lysine supplementation (T3 ). Blood samples were collected on the 1st and 2 3 63rd day of the trail. A close examination of the nutritive effects of treatment of CSC and bypass Methionine and Lysine (M-L) supplementation on hematological and biochemical values in the blood (white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hb), pack cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelets count (PLT), total protein, albumin, globulin, blood urea nitrogen (BUN), creatinine and creatine kinase was carried out. Results: BUN had a tendency to decrease in T2 and T3 (P<0.05) by the end of the trail with compare to control but no significant difference was observed between T2 and T3 . No significant differences were found between treatments in other hematological and biochemical parameters like total protein, albumin, globulin, creatinine and creatine kinase. Conclusion: Bypass Methionine and Lysine have no effect on hematological and biochemical parameters except blood urea nitrogen (BUN) in growing Jaffrabadi heifers.
