Resistance to nematode parasites can be improved by selection, but efforts to include appropriate traits in commercial livestock breeding programs are only a recent development. Procedures for including resistance in breeding programs are similar to those involving other traits. The steps are des...

Breeding objectives were developed for meat sheep in smallholder production circumstances in the tropics. The traits considered were litter size, lambing frequency, pre-weaning, and post-weaning lamb survival to 12 months, ewe survival, lamb live weight at 12-month, mature ewe live weight, consum...

Disease is one of the most important biological constraints to small ruminant production in the many different agroclimatic zones of Africa. Loss of production, high levels of mortality and the cost of drugs are some of the major concerns. Current control strategies include vaccination, medicatio...
