Conference Paper 1992

Autor: Baker, R.L. Lahlou-Kassi, A. Rege, J.E.O. Reynolds, L. Tekelye Bekele Mukasa-Mugerwa, E. Rey, B.

The paper reviews the evidence of genetic resistance to endoparasites both within and between breeds of sheep and goats and assesses the possibilities of breeding for increased resistance. In light of this evidence, ILCA has developed a Pan-African research programme to investigate and characteri...

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...

A comparison of F2 and F6/7 inter-cross lines of mice, derived from CBA and SWR parental strains, has provided strong evidence for several previously undetected quantitative trait loci (QTL) for resistance to Heligmosomoides bakeri. Five QTL affecting average faecal egg counts and/or worm burdens...

Autor: Baker, R.L.

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...

Presents the Orma Boran field observations carried out under tsetse fly challenge on Galana ranch in Kenya since 1980. Their response to trypanosomiasis has been compared to that of the ranch bred Kenya (Galana) Boran. The mean monthly prevalence of trypanosomiasis observed in Orma steers over fi...

Breeds of cattle, sheep and goats have been identified which are genetically resistant and/or tolerant to gastro-intestinal nematode parasites. Mapping and cloning of resistant genes will facilitate Development of new breeds of livestock, which combine this important disease resistance trait with...

Genome-wide quantitative trait locus (QTL) mapping was used to evaluate the genetic basis of resistance to Helgmosomides polygyrus in an F2 cross of SWR and CBA mouse strains that are resistant and susceptible, respectively, to infection. 25 significant QTL affecting at least one of the resistanc...

Report 1996

Autor: Baker, R.L.

There is a large and diverse range of sheep and goat breeds in the world and some of these, particularly the indigenous tropical breeds, appear to have some unique genetic ability to resist or tolerate diseases. This paper reviews the information available on between-breed genetic variation for r...

Red Maasai [Masai] and Dorper sheep were evaluated for their resistance to gastrointestinal nematode parasites (predominantly Haemonchus contortus), productivity and efficiency in experiments undertaken at the Kenyan coast (humid environment) and the Kenya highlands (semiarid environment). It was...
