Milk yield performances in Kenana and Butana cows were examined to determine the influence of age on production. The mean milk yields for the Kenana and Butana herds were 2136 ± 168 and 1807 ± 592 kg produced in a mean lactation period of 283 ± 40 days and 283 ± 57 days respectively. In both herd...

In a comparison of water intake of Boran and Angus-Boran steers over three years, the crossbreds consumed more water per head than the Borans, particularly during the hotter months. There was little difference between the groups on the basis of intake per unit liveweight, and intake per unit live...

Boran (Bos indicus) heifers were immunised by infection with local Theileria parva parva, T p lawrencei and T mutans stocks and treated with parvaquone and later exposed to natural tick and tick borne disease challenge in the Trans-Mara Division of Kenya. The Theileria species parasites in the ch...

A comparison was made of the growth curves for early and late eruptors (steers whose eruption age of the first incisor pair was less than the mean, and greater than the mean respectively). From birth to 195 weeks early eruptors were consistently heavier than late eruptors (P

The mean birth weight of Kenana calves in the herd under investigation was 24.2±2.8 kg. Male calves were 1.3 kg heavier at birth than female-calves. The difference was attributed, parity at least, to longer gestation length in case of the male-calves. Calves born to cows 2½-5½ years old were sign...
