Twenty-seven Boran and 37 Boran x Friesian bulls, weaned at six months of age, were allocated to either receive supplementary diet (16 percent crude protein and 10.8 MJ/kg DM energy) during the dry season or to serve as unsupplemented controls until 21 months of age. Body weight measurements were...

The effect of trypanosomosis on the resumption of postpartum ovarian function and oestrus activity was studied in small East African zebu cows maintained under natural trypanosomosis challenge. This was done through the determination of milk progesterone levels using the enzyme linked immunosor...

Investigates the mineral composition of lake soils drawn from Lakes Ziway, Shala and Abiata in Ethiopia, traditionally believed to improve production and reproduction of both cattle and sheep; tests their efficacy as a mineral supplement for Arsi sheep growth; voluntary feed intake and weight gai...

The study investigated the effect of work on the postpartum estrous cycle length and ovarian activity of crossbred dairy cows used for draught. Sixteen dairy cows were assigned to two dietary feeding regimes (i.e. diet 1=9 MJ ME/kg DM; diet 2=10 MJ/kg DM). The cows in both diets started to work a...

The efficiency of cattle breeding and production depends to a large extent on the reproductive performance of the herd, with the bull playing a major role. Large differences in fertilizing ability between bulls exists, and such differences are due to the characteristics of individual bulls rather...

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...

Research in Kenya has confirmed that Red Maasai sheep are more resistant to gastrointestinal parasites than Dorper sheep and has shown that Small East African goats are more resistant than Galla goats. There is no difference in resistance between the Menz and Horro sheep breeds in Ethiopia. Herit...

The productive performance of indigenous sheep and goats of Ethiopia were evaluated over a period of 2 years (October 1979 to March 1981). Data on age at first parturition, litter size, lambing and kidding intervals, annual reproductive rates, mortality rates and growth rates included.

A total of 179 heifers, primiparous and multiparous Boran cows were assigned to four breeding units and mated over a 4 - month breeidng season in a single-sire mating system. Mean body weight and body condition scores at the beginning of mating ranged from 363 + 6 kg to 388 + 7 kg and from 6.7 + ...
