West African Dwarf (sheep)


West African Dwarf (sheep)

West African Dwarf is a domesticated breed of sheep and is the dominant breed from southwest to central Africa.[1] This breed is primarily raised for meat.[2]

Characteristics

The West African Dwarf is generally black piebald on white. However, tan piebald on white and the blackbelly pattern are found. Rams weigh approximately 37 kg (82 lb), have a well-developed throat ruff and are horned. Ewes weigh about 25 kg (55 lb) and are usually polled (hornless).[1]

On average, ewes produce 1.15 to 1.50 lambs per lambing.[1] This breed grows slowly as evaluated in Nigeria in the last 1970s. The overall growth rates from 0-90, 91-150 and 151–350 days old were 74, 49 and 33 g/day, respectively.[3]. This breed is also highly tolerant of trypanosome.[4] This breed is thought to go into oestrus throughout the year.[5]
