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...

In a trial to evaluate the growth of crossbred calves under semi-arid ranch conditions in Botswana, pure Tswana and crossbred beef cows were inseminated with beefalo and Italian semen or mated naturally with Brahman, Simmental or Tswana bulls. The 424 calves produced were weighed at birth and at ...

Differences in susceptibility of the Small East African breed of goats to an experimental Trypanosoma congolense infection were investigated. The goats were obtained from different areas of East Africa, Morogoro and Arusha (Tanzania), Imbo and Lambwe Valley (Kenya). Morogoro goats were found to b...

Three breeds of cattle, the White Fulani (zebu breed), German Brown and Holstein (European breeds), of the same age, kept under identical conditions were studied to delineate differences in some body fluid charateristics. Data on comparative values of blood contituents, serum constituents and bod...

Anassessment of the relationship between does’ weights at parturition, birth weight and weaning weight, in kids of Malawian local, Boer and their crosses was investigated. Birth and weaning weights for male kids were 3.8 and 20.2 (Boer), 2.6 and 16.3 (Malawian local), 2.9 and 16.0 (Malawian x Boe...

Haematological values of healthy Galla goats have been determined. These values have been found to differ from those reported by other authors in different breeds of goats from various countries. Those values found to be of highly significant difference (P
This study has indicated that differences in susceptiblity to Trypanosoma congolense infection exist among the 3 main breeds of goats in Uganda namely, Kigezi, Mubende and small East African (SEA). The Kigezi goats appeared to be the most susceptibe suffering more severe anaemia, greater retardat...
