Genotype by environment interactions for productivity and resistance to gastro-intestinal nematode parasites in Red Maasai and Dorper sheep
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...

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

A study was carried out from 1994 to 1996 to compare the resistance to naturally acquired gastrointestinal (GI) nematode infections (predominantly Haemonchus contortus) of 88 Galla and 114 Small East Africa (SEA) goats (does) in the sub-humid coastal region of Kenya. Live weights (LWT), blood pac...
