Livestock production in central Mali: Effects of climatic variables on the period of birth and on litter size in traditionally managed goats and sheep
Presents findings of a trial carried out at Elangata Wuas in Tanzania to measure the liveweight development of 1101 goats and 547 sheep kept under ranch conditions, considering the influence of variables such as management system, sex, parity, birth type, season of birth and flock. Analyzes post-...

Livestock production on Masai group ranches. 2. Growth and liveweight in goats and sheep at Elangata Wuas and the factors influencing them
Examines the productivity of goats and sheep on a Masai group ranch in Kenya including pre-weaning mortality and live weight of young. Considers environmental factors affecting the death rate. Constructs three productivity indices to identify a management system.

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...
