Studies on west African dwarf sheep: incidence of perinatal mortality in Nigeria.
A study was conducted on the incidence of perinatal lamb mortality with extension up to 30 days of age (PMR 30) in West African Dwarf sheep in Ibadan, Nigeria, over a three year period. An overall PMR 30 of 19.9% was recorded. This consisted of an abortion rate of 3.0%, a still-birth rate of 2.7% and a neonatal lamb mortality rate of 15.6% up to 30 days of age (LMR).

متن کاملProminent Signs of Oestrusin the West African Dwarf Goat
In order to study the signs of œstrus in the West African Dwarf goat, 28 non pregnant females younger than 24 months of age were used. Most of them (94.7%) had waggled the tail during heat. The frequency of micturition was higher in the presence of the male. The swelling of the vulva was observed in 68.4% of goats in heat. The cervico-vaginal mucus was significantly (P≤0.05) abundant and elasti...

متن کاملDiscriminant analysis of morphometric differentiation in the West African Dwarf and Red Sokoto goats
This study evaluated the usefulness of morphological characteristics to distinguish two important indigenous goat breeds in Nigeria. Fifteen morphometric traits were measured on West African Dwarf – WAD (n = 160) and Red Sokoto – RS (n = 142) goats that ranged in age of up to 19 months and were reared extensively in villages in southern and northern Nigeria. Univariate analysis revealed that th...
