Abstract:
Post milking behaviour of dairy cows has grave influences on their production efficacy as intra-mammary infection (IMI) is related to post milking standing period. A number of genetic and environmental features controls and affect post milking behaviour of dairy cow. The aim of present study was to investigate post milking behaviours and the influence of different factors like parity, stage of lactation, time of milking and seasons on post milking behavioural features, the experiment was conducted on 94 Jersey crossbred cows during total days of lactation in their respective sheds post milking operations. Impact of parity revealed that primiparous cows are having significantly (P<0.01) better post milking standing period (PMSP) as compared to multiparous cows. Seasons shows significant (P<0.01) influence upon PMSP and it is least in rainy seasons because during rainy weather there is high temperature-humidity index which is more stressful for dairy animals in tropical conditions. Cows during evening milking time showed significant (P<0.01) improved PMSP as compared to morning milking time because during evening there is availability of fresh green fodder in the feeding trough just after milking process. It can be concluded from the obtained investigation from this study that seasons, parity, stages of lactation and time of milking significantly showed influence on post milking behaviours and post milking standing period of Jersey crossbred cows in tropical conditions.
