It is well accepted that the growth rate of beef animals affects the economic returns of commercial ranchers. The aim of this study was therefore to investigate the effects of certain environmental factors on the birth weight and growth in a herd of Boran cattle bred at the Adamitulu cattle Impro...
The luteolytic effect of prostaglandin F2á (PGF2á) during the confirmed luteal phase of the oestrous cycle was evaluated in ten Boran and ten Boran x Friesian cross-bred heifers. Following injection with 25mg Lutalyse, animals were bled every 6 h for 96 h and plasma progesterone (P4) determined ...

Observations of milk yield, and calf growth and conversion rate, on three types of cattle in Ghana. II. Effects of plane of nutrition
The work reported in this paper was initiated to estimate the age at first calving in herd of Kenana cattle with particular reference to the influence of year and season of the birth on age of heifers at calving. It included a feeding trail to elucidate the effects of improved nutrition on body d...

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...
