The present study was conducted to determine the influence of season on the body weight (BW) and zoometric characteristics of Nigerian goats. A total of 1000 male and female goats belonging to two breeds (West African Dwarf, WAD and Red Sokoto, RS) and 5 age groups were evaluated in the wet as well as dry season using a 2x2x2x5 factorial arrangement experimental of completely randomized design. The zoometric traits considered were body length (BL), heart girth (HG), wither height (HW), neck length (NL), and neck circumference (NC). The results showed that season significantly (p<0.05) affected the overall BW, HW, NL and NC. Measurements in the wet season were significantly higher than those measured during the dry season with the exception of BW(15.19 vs 18.90 kg) and NC(22.54 vs 23.33 cm). Mean BW and all the zoometric measurements were significantly (p<0.05) higher in RS than WAD goats, and male goats had significantly (p<0.05) higher body weight and zoometric measurements than female goats. Interaction between season and age, season and breed, age and sex and between breed and age were significant (p<0.05). It was concluded that sex, age and season have interdependent implications on the BW and zoometric characteristics of RS and WAD goats. Adequate consideration to these factors is therefore recommended for effective management of goats.Effects of age,Sex,Season andBreedArticle
