A genetic study of the grading-up of the East African zebu to the Indian Sahiwal has been undertaken on records, covering about 25 years, from three livestock Improvement Centres in Kenya. It appears from this study that the indigenous East African zebu cow has only about half the genetic potenti...
The productive performances of Tswana and Boer goats, and Dorper sheep were investigated. Comparative performance on productivity per ewe/doe and young mortality in pure Tswana and Boer goats and Dorper sheep in Botswana were examined. The local breeds were superior for use in communal areas prac...
A crossbreeding experiment was carried out between two local strains of Mandarah (MN) and Matrouh (MA) chicken. Thirty-four sires and 400 dams from each strain were used to produce four genetic groups. Body weights of 3067 chicks at hatch (BW0), 4 (BW4), 8 (BW8), 12 (BW12) and 16 (BW16) weeks of ...

Compares influence of various feeding systems on meat production from Brahman x Fulani crossbreeds and indigenous breeds of zebu cattle at the Wakwa research station, Cameroon. The response to intensive fattening was better for the crossbred steers (Brahman x Fulani) than for the local breed (Ful...

In a trial whereby a large number of cows were needed to calve at approximately the same time, opportunity was taken to establish a crossbred cow population at the International Trypanotolerance (ITC). A slight improvement in the traditional husbandry system revealed a great productivity potentia...

Menz sheep are indigenous to the highlands of Ethiopia, and highly valued for their meat and wool production. The area is characterized as a low input mixed barley-sheep production system. In 1998, a selection experiment was setup to evaluate the response of Menz. sheep to selection for yearling ...

There is growing interest in the environmental benefits of grazing by cattle, yet little information is available regarding the levels of production that might be achieved on semi-natural rough grazing (SNRG). The overall aim of this research was to assess the performance of native and ‘improved’...
