abstract: Aims of study was to determine the relationship between steaming up with colostrum production at different milking times. The animals used in this research were 36 pregnant Holstein-Friesian (HF) cows. The method used in this research was a case study. Samples were determined with purposive sampling. The selected animal was divided into two groups, T1 (control) and T2 (steaming up). The steaming up was done two weeks prior to calving. The total average of colostrum production from HF cows that were in T2 group was 11.96±2.40 liter/cow/day, while the mean value of colostrum production from HF cows that were in T1 group was 8.05±1.80 liter/cow/day. The average colostrum production that was collected at morning milking from cows in T2 group was 6.38±1.36 liter/cow/day and at afternoon milking was 5.58±1.11 liter/cow/day, significantly higher than T1 group which was 4.22±0.92 liter/cow/day at morning milking and 3.83±0.90 liter/cow/day. The result of the regression equation on morning milking is Y = 2.059 + 2.159x. This means that steaming up treatment can increase colostrum production by as much as 2.159 liters at morning milking. While the result of the regression equation on afternoon milking is Y = 1.753 + 2.078x. This means steaming up treatment can escalate the colostrum production as much as 2.078 at afternoon milking. That equation is used as the basis for estimating the relationship between steaming up with colostrum production at both milking times, with a correlation coefficient (r) between steaming up and colostrum quantity at morning milking is 0.692, which means the relationship is in the strong category. Meanwhile, the relationship between steaming up and colostrum yield at afternoon milking is 0.666, which means the relationship is also in the strong category. It was concluded that steaming up had a very significant effect at both milking times in Holstein-Friesian cows. © (2023), (Scienceline Publication). All Rights Reserved.
