Parasitic nematodes are among the most common and economically important infectious diseases of grazing livestock, especially in small ruminants in the tropics and subtropics in Kenya the control of gastrointestinal nematode infections in sheep and goats is usually made with synthetic anthelmin...

Divergent breeding lines of Romney sheep, selected as lambs for consistently high or low faecal worm egg count (FEC) following natural multi-species challenge by nematode parasites, were established in New Zealand at Wallaceville Animal Research Centre in 1979 and at Rotomahana Station in 1985. I...

Sustainable livestock improvement cannot be guaranteed for most tropical areas of the world without utilization of the evolutionary adaptation of the indigenous livestock breeds. The paper summarizes the adaptive traits of indigenous tropical breeds, presents a case for their evaluation and discu...

Sub-Saharan Africa is rich in animal biodiversity. Over 95 percent of the continent's domestic ruminants are indigenous. In Africa, indigenous livestock breeds support the majority of smallholder rural farmers for whom these genetic resources are important for improved nutrition, income and as in...
