Abstract

This study analyzed the relationships among body size, udder size, and milk production in Anglo-Nubian dairy goats. The study used 20 samples. The research used an observational method at Lobi Farm, Pondok Kubang, Central Bengkulu, and used both primary and secondary data. Primary data included body size (chest girth, chest width, and hip width) and udder size (udder length, width, height, and volume), collected through direct field observations. We obtained secondary data on milk production from farm records. We analyzed the data using correlation and simple linear regression tests. The results showed that body size variables, including chest girth, chest width, and hip width, had very weak and non-significant relationships with milk production. The coefficients of determination (R²) for these variables were very low, indicating minimal contribution to milk production variability. In contrast, udder size exhibited more variable relationships. Udder width showed a moderate correlation and the highest contribution to milk production (R² = 0.253), followed by udder volume. Meanwhile, udder length and height had relatively smaller effects. In conclusion, body size cannot be used as a primary indicator for predicting milk production in Anglo-Nubian goats. Udder characteristics, particularly udder width, have greater potential as selection criteria for improving milk productivity. Other factors such as genetics, nutrition, and management practices also play significant roles in determining milk yield.
