Popis: The present study was aimed to evaluate the effect of seasonal variation in Temperature Humidity Index (THI) on milk production and composition in Murrah buffaloes. Eight adult lactating Murrah buffaloes of 3-5 years of age and insecond to fourth lactation were selected in summer and winter season. Meteorological variables such as ambient temperature and relative humidity were recorded and THI was calculated during the period of study. Milk samples were collected from Murrah buffaloes and evaluated for the concentration of milk fat, protein, SNF, lactose and salt. The data was analyzed using SPSS v.20. The results indicated that average milk production, milk fat, protein and SNF decreased significantly (p0.05) in between seasons. From the present study it was concluded that high THI imposes significant heat stress and negatively affects milk production and composition in Murrah buffaloes. Hence, additional feed, shelter and management practices might be adopted to overcome the negative effects of thermal stress and also to optimize milk production of the animals.
