Milkability differences based on lactation peak and parity in Holstein cattle
Original language description
The aim of this study was to evaluate differences in milkability based on lactation peak and parity in Holstein cattle. Milk yield, actual milking time, milking time differences, the occurrence of bimodal milk flow, average milk flow and partial milk flows within the first two minutes of milking were monitored for each milking during the first 120 days in milk (DIM). The Holstein cows (n = 135) were divided into groups according to the day when they achieved lactation peak (lactation peak group (LPG): 0-30 DIM, 30-60 DIM, 60-90 DIM and 90-120 DIM) and parity (primiparous and multiparous cows). The obtained results suggested that milkability parameters were better for cows that achieved lactation peak between 60-90 DIM and sooner. The highest milk yield, 19,65 kg, was achieved by multiparous cows in LPG30-60. The primiparous cows in LPG60-90 had the lowest occurrence of bimodal milk flows and fastest milking. The primiparous cows in LPG0-30 performed poorly in most milkability parameters. The highest
