Elucidating Milking Operation in Jersey Cross-bred Cow for Higher Quantity and Quality of Milk at New Alluvial Zone

Background: At new alluvial zone of WB, milk production has not received adequate attention and this has been a major obstacle in dairy development. Methods: Experiment was conducted on 14 Jersey crossbred cows to compare 2 milking operation viz. flat-parlor machine (group-I) and full-hand (group-II) milking at NDRI, ERS (WB). Result: The statistically analysed data of 280 milk samples revealed that milk quantity was significantly higher in group-I as compared to group-II but SCC, CMT, SFMT were significantly lower in group-I than group-II. Other quality parameters (MBRT, fat, SNF, TS, protein, FPR) were varied non-significantly between groups. The time required for milking/animal was significantly higher in group-II than group-I but milk extraction rate significantly lower in group-II than group-I. BCS of animals of both groups varied non-significantly with in a normal range. Significantly higher milk quantity was recorded during morning than evening milking session in both groups. Non-significant variation of SCC, CMT, SFMT, MBRT, fat, SNF, TS, protein, FPR were found in between two milking sessions of each group. The milk extraction rate was significantly lower during evening than morning whereas time required for milking/animal was higher in morning than evening session in both groups. It can be concluded that higher quantity and quality of milk can be produced in flat-parlor machine milking operation in comparison to full-hand milking operation in Jersey crossbred cows at new alluvial zone of West Bengal.
