Research in Kenya has confirmed that Red Maasai sheep are more resistant to gastrointestinal parasites than Dorper sheep and has shown that Small East African goats are more resistant than Galla goats. There is no difference in resistance between the Menz and Horro sheep breeds in Ethiopia. Herit...

The origin of the American hair sheep is diverse with likely early introductions from the Canary Islands, followed by introductions from the African and European continents. Using 14 microsatellite loci, we studied 3 American hair sheep (St. Croix, Barbados Blackbelly, and Gulf Coast Native), 6 E...

This paper summarises the adaptive traits of indigenous livestock breeds, presents a case for their improvement and outlines possible utilization strategies. Though the adaptive attributes of indigenous breeds of other species recognised, the discussion concentrates mainly on cattle. The discussi...

The note is divided into five parts, viz, sampling methods, multicollinearity or intercorrelation, autocorrelation, and estimable and testable functions. The first part discusses sampling procedures, sample size determination, random sampling, sampling by deliberate stratification, blocking and i...
