Abstract


A study was conducted in two local government areas (Jos South and Riyom) in northern part of Plateau State, Nigeria in 2018 to determine the effect of sex, age, reproductive statue, coat colour and season on weight gain of West African Dwarf goats. A total of 810 goats were randomly sampled on repeated basis for seven months and grouped into five according to sex, age, reproductive statue, coat colour, and season. The goats were restrained, identified by colour, characteristics and diagnosed (i.e whether pregnant, lactating or dry) and weighed using simple weighing scale on repeated measurement basis for 7 months and all parameters were recorded and analyzed. The result showed an overall mean weight of 11.97 ± 0.24kg for all the animals sampled. There was a significant difference (P<0.001) in body weight of goats according to age. Goats with age ≥ 8months had the highest weight (13.81kg) than those ≤ 7months (10.14kg). There was a significant difference (P<0.001) in body weight of goats according to sex, age, reproductive statue and season. Coat colour had no influence on body weight of the animals. The study concluded that sex, age, reproductive statue and season has effect on body weight of the animals and recommends that sex, age, reproductive statue andseason be considered in any breeding programme.
