Characterization and Correlation of Udder Morphology with Milk Production of Etawah Crossbreed (PE) Goat. 1Graduate Program, Faculty of Animal Science, Brawijaya University, Malang 65145, East Java, Indonesia. Abstract The Etawah Crossbred Goat (PE) demonstrated potential as a commercial dairy goat in tropical regions susceptible to heat stress. However, information regarding milk production and udder-teat morphology in PE goats was limited. This study aims to characterize udder-teat morphology and evaluate its relationship with milk production. Data were collected from 87 lactating female PE goats at BPTU-HPT Pelaihari, South Kalimantan. Nine variables were measured: daily milk yield (DMY), teat length before and after milking (TLB, TLA), udder length before and after milking (ULB, ULA), udder width before and after milking (UWB, UWA), and udder circumference before and after milking (UCB, UCA). The study employed t-tests, single-factor ANOVA followed by Duncans test for significant results, and Pearson correlations for statistical analysis. Results revealed that lactation age was highly significantly affected (P<0.01) on DMY. Goats <90 days post-weaning produced an average of 0.52 liters, while those >90 days post-weaning yielded 0.36 liters. Notably, the study found highly significant positive correlations (P<0.01) between DMY and UWB (r=0.589), UCB (r=0.565), UWA (r=0.401), and UCA (r=0.273). In conclusion, this research contributes valuable insights for improving dairy goat farming in tropical regions. Characterizing udder-teat morphology and its relationship with daily milk production can serve as a foundation for targeted breeding programs to enhance milk productivity in PE goats.
