ABSTRACT
A commercial beef cattle ranching scheme was begun in 1964 in western Uganda in an area that had been cleared of the tsetse fly, G. morsitans, by a combination of clearing most of the bush and by spraying with insecticides. A beef cattle research station was established specifically to provide technological support in areas of beef cattle breeding, husbandry, and pasture and range management. An important part of the investigations was a major effort in beef cattle breeding that was organized to yield early results. The Boran has long been regarded as a standard for comparison in beef production programs in East Africa. The Angus was identified for characterization as a representative of Bos taurus breeds of small to intermediate size that are used exclusively in beef production programs in temperate climatic zones. Males of the Angus and Red Poll breeds were mated to females of the Ankole, Boran, and Zebu breeds.
