Effect of dietary betaine supplementati on haematological parameters in male goat kids

Abstract

Goats play a crucial role in livestock farming in India, particularly in arid and semi-arid regions, due to their ability to withstand high temperatures and limited water availability. With rising global temperatures, improving heat tolerance in goats is essential for sustainable farming. Betaine, a naturally occurring feed additive, has shown potential in enhancing resilience against heat stress, improving nutrient absorption, and supporting physiological functions. This study aimed to assess the effects of betaine supplementation on hematological parameters in male goat kids. Eighteen male goat kids (4–5 months old) were divided into three groups: control (T1), betaine 2 g/day (T2), and betaine 4 g/day (T3). Blood samples were collected at intervals over four months. Results indicated a significant increase (p<0.05) in total erythrocyte count, total leukocyte count, hemoglobin levels, and packed cell volume in betaine-supplemented groups, particularly T3. The improved hematological parameters suggest that betaine enhances red blood cell production, immune function, and overall physiological health. These findings highlight betaine’s role as a cost-effective nutritional strategy to mitigate heat stress in goats, supporting better growth and productivity. Incorporating betaine in goat diets could improve heat resilience and benefit small-scale farmers in hot climates.
