Thirty-six healthy Tarai buffaloes (280-350+-10 kg body weight, 2nd to 4th parity) were selected to investigate their milk composition. The selected animals were divided into four groups having nine buffaloes in each group as, each group from early, mid and late lactation and another group of dry buffaloes. The study carried out in four seasons and climatic variants of temperature and relative humidity were recorded for each month where temperature-humidity index (THI) was calculated. Results of milk composition with advancing in lactation stage showed significantly (P LT 0.05) higher values for milk fat, urea and total solids. In season-wise, milk constituents of fat, protein and total solids were found significantly (P LT 0.05) higher during winter season except higher milk urea in summer season. Other milk constituents include lactose, SNF and pH were remain unaffected throughout the lactation period and seasons. Milk somatic cell count (SCC) is affected by both lactation period and seasons but the variations stood non-significant. Calculated THI in tarai region was found higher (79 LT THI LT 84) during summer and rainy seasons. It may be concluded that Tarai buffalo performances are affected by seasonal variations and lactation period as indicated in milk composition variations. Thus, Tarai buffalo could perform better if improvement in their management system of housing and feeding of quality nutrients.
