Journal Article 1996

Autor: Mackinnon, M.J. Thorpe, W.R. Baker, R.L.

Crossbreeding parameters and variance components were estimated for lactation and reproductive traits of crosses between the Sahiwal, Brown Swiss and Ayrshire breeds in a dairy herd in sub-humid coastal Kenya. An individual animal model was fitted to the data with a fixed effect for 20 distinct 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...

Journal Article 2003

Autor: Behnke, J.M. Iraqi, F.A. Menge, D. Baker, R.L. Gibson, John P. Wakelin, D.

The host-protective immune response to infection with gastrointestinal (GI) nematodes involves a range of interacting processes that begin with recognition of the parasite's antigens and culminate in an inflammatory reaction in the intestinal mucosa. Precisely which immune effectors are responsib...

Since the publication of the mouse genome, attention has focused on the strains that were selected for sequencing. In this paper we report the results of experiments that characterized the response to infection with the murine gastrointestinal nematode Heligmosomoides polygyrus of eight new strai...

The effects of breed (Menz and Horro), season (wet and dry), and the breed by season interaction on production and response to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Longistrongylus elongata and Trichostrongylus spp. and a small proportion of Haemonc...

The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involves mating, for each breed, 150 ewes with 10 rams to lamb at the beg...

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...

Autor: Baker, R.L. Mwamachi, D.M. Audho, James O. Thorpe, W.R.

This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...

Genetic parameters for growth traits in Sabi sheep were estimated using from data records of 4123 lambs from 130 sires and 1131 dams collected between 1984 and 1994. Reproduction traits and lamb survival to weaning were analysed fitting a sire threshold model. The direct additive contribution t...

A study was conducted to investigate the effect of season on, and to estimate heritabilities of, and genetic correlations among, semen and spermatozoa characteristics and the relationship of these characteristics with measures of testicular or scrotal size in 6-, 9- and 12-month old ram lambs of ...
