Abstract

Improvement in production performance of indigenous cattle breeds becomes essential to make them economically viable. Due to increased environmental temperature cattle undergo heat stress. Milk production is adversely affected due to heat stress. In the present study records maintained at Cattle Cross Breeding Project, Vasantrao Naik Marathawada Krishi Vidyapeeth, Parbhani (Maharashtra) for the period of 1995-2010 were utilized to study monthly lactation milk yields and climatic factors. The climatic parameters considered were temperature, relative humidity, wind velocity, sunshine hours and dry and wet bulb temperature along with THI. The data on monthly lactation milk yields of cows calved during cold, hot, south-west monsoon and post monsoon seasons were considered. Correlation and multiple regression analysis were used to investigate various sources of variation in monthly lactation milk yields. Monthly lactation milk yield data were analyzed to ascertain the effect of climatic attributes and to know their association with monthly lactation milk yields. The higher milk production during post monsoon was attributed to cows calved during that season whose milk production was favoured by post monsoon climate. Seasonal climate may be the responsible factor to influence the milk production levels. The average monthly milk production (359.18+25.85 liter) was more during post monsoon season followed by cold (326.81+20.48 liter), south-west monsoon seasons (326.60 +20.45 liter) and hot (245.78+19.13 liter), respectively.
