AbstractAn experiment was conducted on 20 lactating Kankrej cows divided in four groups according to lactation number one to four and initial stage of lactation with almost same production. Highly significant (P <0.01) difference was observed for let down time in cold and dry season (61.54 sec. ) as compared to hot and humid season (68.13 sec.), milking time in hot and humid season (245.72 sec) as compared to cold and dry season (260.02 sec.) and milk yield/ milking in cold and dry season (4.300 Kg ) as compared to hot and humid season (3.860 Kg ) while, significant (P< 0.05) difference was observed in milk flow rate in cold and dry season (0.990Kg /minute ) as compared to hot and humid season (0.950 Kg / minute).
