Heritability of susceptibility to infection with Theileria parva was estimated from full sib families of Rhipicephalus appendiculatus ticks. Male and female ticks of 2 stocks were mated singly. Nineteen full sib families of the Mugufa stock and 17 full sib families of the Kiambu stock were obtain...

Nine hundred and thirty-six East African Zebu village calves in an area of high trypanosomiasis risk in south-western Ethiopia were monitored monthly with their dams from birth to 3 years of age. Mean packed red cell volume (PCV) and the frequency of detected parasitaemia were calculated for each...

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...
