African Researchers Use Gene Editing and Other Tools To Breed Heartier Livestock

wooloohoo shares a report: Livestock researchers in Africa are looking to genome editing and other new technologies to identify genes that could help them tame the spread of a parasite that spreads sleeping sickness in animals and humans. In addition to work aimed at eradicating African trypanosomiasis, scientists at the International Livestock Research Institute (ILRI) in Nairobi are using gene editing to introduce such desirable traits as heat tolerance and disease resistance into cattle and chickens, said Prof. Steve Kemp, program leader in livestock genetics at ILRI. However, he said the effort is still at the preliminary research stage. African animal trypanosomiasis is a parasitic disease that causes serious livestock losses due to anemia and lower reproduction rates, according to the Center for Food Security and Public Health. Losses in cattle are especially prominent, though other animals, including dogs, can also be affected. Untreated cases can be fatal, and the mortality rate is high in some outbreaks. "Eradicating African animal trypanosomiasis is extremely important as we estimate that Africa loses US$1 billion annually due to human and livestock diseases," Kemp said. The people keeping livestock have experienced huge losses due to animal diseases, said Abdikadir Mohamed, chief executive officer of the Kenya Livestock Marketing Council (KLMC). "This leads to people getting poorer. Some sickly animals are rejected during market days, yet they come from far to sell the livestock. There is also a security threat as herders go back with their livestock. We need to stop these persistent diseases by available technologies."Read more of this story at Slashdot.
