Analysis of the relationship between udder characteristics and milk production in dairy cows

\nThis research aims to investigate the relationship between udder characteristics such as udder width, udder height, udder depth, and milk production in dairy cows. The research was conducted on 100 heads of Crossbreed Friesian Holstein (CFH) lactation period owned by various small-scale farmers in KAN Jabung, Malang Regency. Data analysis was calculated using regression analysis and correlation. The research showed that the average udder width of dairy cows was ±12 cm, udder height was ±19 cm, udder depth was ±21 cm, and milk production was ±15 litres/day. linear regression analysis the relationship between udder width and milk production, the equation obtained was Ya = 1.50 + 1.11Xa with a correlation of 0.50. The relationship between udder height and milk production showed Yb = 14.59 + 0.01Xb with a correlation of 0.0063. The relationship between udder depth and milk production resulted in the equation Yc = 20.66 - 0.27Xc with a correlation of 0.16. The research demonstrates a moderate positive relationship between udder width and milk production. Conversely, the relationships between udder height, udder depth, and milk production are very weakly positive. It is crucial to also consider other influencing factors, such as genetics, feed management, health conditions, and production phases, which can significantly impact milk production.\n
