Murayi, T.Sayers, A.R.Wilson, R.T.[La productivité des petits ruminants dans les stations de recherche de l'Institut des sciences agronomiques du Rwanda]La productivité des petits ruminants dans les stations de recherche de l'Institut des sciences agronomiques du Rwanda
Autor: Wilson, R.T.

The result of an intensive 15 months study of 10 flocks of indigenous sheep is recorded. Lambing rates approach 1.5 lambs per ewe per year, but a death rate of 23 percent and on off take of 27 per cent, means that flock numbers are probably slightly declining. Twins account for 14 per cent of all...


Wilson, R.T.[Studies on the livestock of southern Darfur, Sudan. III. Production traits in sheep]Studies on the livestock of southern Darfur, Sudan. III. Production traits in sheep
Autor: Wilson, R.T.

Examines sheep and goat husbandry including breed types and ownership; nutrition and productivity. Tabulates their contribution to liveweight biomass, meat production, and registered slaughtering. Shows some measured production parameters for African goats and sheep in semi-arid areas. Looks at t...

Data on weight and weight gain of East African long-fat-tailed sheep, starting in 1974, are analysed. Birth weights averaged 2.59 kg. Weights were 11.6 kg at 90 d, 28.0 kg at 12 mo, 29.3 kg at 18 mo and 35.4 kg at 5 yr. Preweaning daily gains varied from 94 g to 157 g in the period 1974 to 1984 a...

In an examination of the productivity of goats and sheep on a Maasai group ranch in Kenya, estimated least-squares means for pre-weaning mortality were 28.6% for goats and 32.1% for sheep. Three productivity indices based on total live weight of young produced per female per year, per kg female p...

Shugor, Dubasi and Watish sub-types of Sudan Desert sheep were evaluated on the basis of 3 productivity indices (weight of lamb weaned/ ewe/yr, weight weaned/kg ewe/yr and weight weaned/kg 0.75/ewe/yr). Components used to construct the indices were litter weight at 120 d, parturition interval, su...
