Prospects of breeding small ruminants for resistance to internal parasites

Autor: Woolaston, R.R. Baker, R.L.

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...

Evaluation of the phenotypic performance of a Red Maasai and Dorper double backcross resource population: Natural pasture challenge with gastro-intestinal nematode parasites

Autor: Mugambi, J.M.M. Audho, James O. Baker, R.L.

Six first cross (F1) Red Maasai X Dorper rams were mated to both Red Maasai (R) and Dorper (D) ewes to produce 1342 double backcross progeny (672 3/4 D/1/4 R and 670 3/4 R/1/4 D lambs born alive). These six double backcross resource families are being used to identify quantitative trait loci con...

Effects of breed and dietary protein supplementation on the responses to gastro intestinal nematode infections in Ethiopian sheep

Autor: Haile, Aynalem Tembely, S. Anindo, D.O. Mukasa-Mugerwa, E. Rege, J.E.O. Yami, A. Baker, R.L.

The effects of breed and dietary protein supplementation on the development of resistance and resilience to gastrointestinal nematode parasites (endoparasites) were examined in artificially infected Horro and Menz lambs from 4 to 12 months of age. The factorial design involved two breeds, two inf...

Evaluation of the phenotypic performance of a Red Maasai and Dorper double backcross resource population: Indoor trickle challenge with Haemonchus contortus

Autor: Mugambi, J.M.M. Audho, James O. Njomo, S. Baker, R.L.

Six F1 Dorper (D) x Red Maasai (R) rams were mated to both D and R ewes to produce backcross lambs. These six double backcross resource families are being analysed to identify quantitative trait loci that may be controlling resistance to gastro-intestinal (GI) nematode parasites, mainly Haemonchu...

Resistance of Sabi and Dorper ewes to gastro-intestinal nematode infections in an African semi-arid environment

Autor: Matika, O. Nyoni, S. Wyk, J.B. van Erasmus, G.J. Baker, R.L.

Sabi and Dorper ewes were evaluated for resistance to gastro-intestinal nematode parasites (predominantly Haemonchus contortus) at the Matopos Research Station in Zimbabwe. Live weights (LWT), blood packed red cell volume (PCV) and faecal egg counts (FEC) were recorded at mating, 1 month before...
