Abstract
A study was conducted to assess effects of dietary betaine supplementation on haemato-biochemical profile, milk yield and composition, SCC, biochemical characteristics in lactating Deoni cows. Twelve lactating cows were randomly divided into control and treatment group with six in each group. Control group was fed basal diet alone whereas treatment group was supplemented with anhydrous betaine hydrochloride @ 15 g/ day in the diet during the study period of 8 week in addition to basal diet. The average daily milk yield improved significantly (P<0.05) in treatment group from 5th week; milk fat and solids not fat from 3rd week of after supplementing betaine. There was no significant difference in milk lactose level between two groups during the study period. Somatic cell count in the milk declined significantly (P<0.05) in betaine supplemented Deoni cows from 4th week of study. There was no difference between two groups in TEC, Hb, PCV and TLC. Percentages of lymphocytes were significantly higher and that of neutrophils were lower in treatment group as compared to control. The concentration of cholesterol, triglycerides and BUN were significantly (P<0.05)decreased from 4th week and total proteins increased from 2nd week of betaine supplementation in lactating Deoni cows. There were no significant differences in plasma electrolytes in betaine supplemented groups compared to control, although plasma sodium and potassium were numerically higher and chloride levels were numerically lower when compared to control group. It can be concluded that dietary betaine supplementation to lactating Deoni cows enhances milk yield and improves milk composition and udder health.
