Observations were made of the ages at first appearance of each pair of permanent incisors (‘eruption age’), and the time from first appearance to full eruption of each pair (‘eruption’), for Large East African Zebu cattle (Boran). For females the eruption ages were found to be 108.5±9.9 weeks, 13...

The reproduction of the Kenana cattle was studied to establish the service period (SP), calving interval (CI) gestation period (GP), and economic production characteristics. Age of cow had significant effect on SP and highly significant effect on calving interval. The variations in the SP and in ...

Animal genetic resources conservation and management depend on national identification of the indigenous adapted breeds of cattle. This paper describes the indigenous cattle breeds of Mozambique. Detailed descriptions of their habitat and husbandry methods, breed characteristics and population in...
Presents estimates of some of the phenotypic and genetic parameters of East African Zebu cattle in West Kenya with respect to milk production. Milk production data at the Baraton, Maseno and Sangalo livestock improvement centres, covering a period of twenty-five to thirty years were analysed. The...
Bovine theileriosis caused by Theileria parva continues to be a major economic problem in many parts of Eastern, Southern, and Central Africa. Due to the unsustainable nature or the present control method-using toxic acaricides to kill ticks - alternative control methods are being sought. Live va...
The recent FAO/UNEP consultation on Animal genetic resources conservation and management stressed the importance of indigenous, adapted breeds of cattle. Relatively little is known of the indigenous cattle breeds of Ethiopia. This article, in describing the breeds and their environmental backgrou...
The blood values of the German Brown, N'Dama and their three-quarter, half and quarter hybrids were studied to ascertain the effects of crossbreeding on haematological parameters. The red blood cell (RBC) and white blood cell (WBC) counts and packed cell volume percentage (PCV) were significantly...

Comparative studies on two types of East African zebu (Bos indicus) Boran cattle, on a beef ranch in Kenya, have indicated that a Boran type bred by the Orma tribe has a superior response to tsetse fly challenge. The Orma Boran when compared with an improved Boran was found to have lower trypanos...
