Abstract

Eighteen Jersey grade cows of third or fourth lactation and in second and third month of lactation maintained under thatch, CI sheet and asbestos roof in three different seasons pre-monsoon (April-May), monsoon (June-Aug) and winter (Dec-Jan) season respectively. Season had highly significant (P<0.01) effect, while roof and season x roof interaction did not have significant (P>0.05) effect on the maximum temperature, while roof had significant (P<0.05) and season had highly significant (P<0.01) effect, while season x roof interaction did not have any significant (P>0.05) effect on the average minimum temperature in the present study. In case of relative humidity roof had significant (P<0.05) and season had highly significant (P<0.01) effect, season x roof interaction did not show significant (P>0.05) effect. The average daily feed, (green, dry and concentrates) consumption differ significantly (P<0.01) among seasons while roof and seasons x roof interaction did not reveal any significant (P>0.05) effect. In case of milk production, season showed highly significant (P<0.01) effect on the milk yield of the cows while roof and season x roof interaction did not influence the trait significantly (P>0.05).
