Abstract

The present study was conducted with an objective to determine the phenotype and characterize the lesser-known indigenous Macherla goat of Andhra Pradesh, on the basis of randomly sampled individuals (n= 771) from 24 villages across the breeding tract. The research focused on habitat, body biometry, and growth of these goats. Macherla goats were observed to be of medium to large size, exhibiting three primary coat color patterns: predominantly patchy (84.6%), followed by plain (12.0%) and spotted patterns (3.4%). Horn morphology revealed that curved horns were most prevalent, followed by straight horns. All the goats of this genetic group had pendulous ears and the head profile was slightly convex in majority. Tail shapes included both curved and straight variations, while the back exhibited both straight and sloping characteristics. The overall least-squares mean for height at withers for individuals over 36 months was recorded at 91.0 ± 0.6 cm (n=199). Specifically, bucks measured an average of 96.5 ± 1.0 cm (n=18), whereas does measured 85.4 ± 0.4 cm (n=181). Statistical analysis indicated that sex had a significant effect on body measurements in the >36month age group. The least-squares means for body length and chest girth for individuals over 36 months were 83.8 ± 0.6 cm and 86.0 ± 0.6 cm, respectively. Adult body weights for individuals over 36 months were 54.0 ± 0.7 kg for males and 42.0 ± 0.3 kg for females.
