During the first 76 days of lactation, primiparous cows were observed to determine the effects of varying frequencies of pre-partum udder massage (45, 30 or 15 massaging sessions on alternate days during last trimester of pregnancy) on temperament score, milk letdown time, milk flow rate, and frequency of urination and defecation. During milking, the restlessness of the animals that had been exposed to pre-partum udder massage was reduced significantly compared to animals in the control group. The median value of milk letdown time varied from 23 to 31 s while the median value of milk flow rate varied from 13 to 16 g/s in the massaged groups compared to 46-50 s and 8-9 g/s, respectively in the control group. All of the differences were significant. Both urination and defecation frequencies were significantly high up to the 16th day of lactation in the non-massaged group. Conclusions stated that udder massaging for 30 sessions would reduce the level of fear in primiparous cows and also facilitate clean milk production.
