A total of 1,000 semi‐intensively managed goats belonging to two breeds—West African Dwarf (WAD) and Red Sokoto Goat (RSG) in equal proportion (500:500)—were purposively sampled across four local government areas. Six age categories (<1, 1, 2, 3, 4, and >4 years) were represented. The objective was to evaluate morphometric traits and their association with body weight in both breeds.
The predominant coat colours observed in WAD goats were brown (37.4%) and black (21.0%), whereas brown coloration occurred in approximately 60% of the RSG population. Both breeds displayed varying degrees of black, brown, and white shades. Stomach girth recorded the greatest mean values among morphometric dimensions, whereas horn length showed the lowest. Overall, Red Sokoto goats exhibited superior body weights and morphometric measurements when compared to West African Dwarf goats.
In WAD goats, heart girth (HTG), body length (TBL), height at withers (GHT), and stomach girth (SGT) ranged from 48.24–52.42 cm, 41.81–44.29 cm, 41.74–43.36 cm, and 57.49–68.59 cm, respectively. The corresponding ranges for RSG were 56.84–62.97 cm, 52.96–61.57 cm, 52.83–53.43 cm, and 63.76–80.12 cm, respectively. Among WAD goats, the mean body weight of young females (<1 year) and adult females (>4 years) was 2.75 kg and 17.63 kg, while males of the same age groups averaged 1.94 kg and 17.18 kg, respectively. In RSG, mean body weights for young and adult females were 3.40 kg and 19.29 kg, whereas males weighed 2.32 kg and 18.14 kg, respectively.
Female goats displayed higher morphometric measurements than males, except for face length (FCL), ear length (EAL), and horn length (HRL). Phenotypic correlation coefficients ranged from 0.204 to 0.955, with all morphometric traits showing significant (p < 0.01) positive correlations with body weight in both breeds; however, correlations were generally higher in RSG than in WAD goats. Regression models indicated that stomach girth (SGT) was the strongest predictor of body weight, explaining 90.3% of variation in WAD and 91.2% in RSG. Heart girth (HTG) was the second best predictor, accounting for 83.5% and 88.8% of body weight variation in WAD and RSG, respectively.
