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...

In alley farming, crop response to mulching is the most important determinant of whether or not the use of prunings for feeding animals is economic. The aim of this paper is to use some recent agronomic and animal nutrition trial data to reassess whether it is economic to add small ruminants to a...

An experiment was carried out over 2 years period to investigate effect of levels of browse supplementary offered to West African Dwarf (Djallonke) sheep on productivity. The results of this on-station trail showed that overall lambing interval was 239 days (ranging from 262 days to 226 days).Bir...

This study quantifies comprehensively both within and between breed differences in resistance to natural infection with gastrointestinal parasites. This research programme was developed from an earlier study in coastal Kenya involving Dorper and Red Maasai X Dorper sheep. It is now part of an ILC...

Studies the within-and between-breed differences in resistance to natural infection with gastro-intestinal parasites and identifies genetic markers to aid in the selection of animals. Data analysed include PCV (Packed Cell Volume), live weight from birth to 360 days and faecal egg counts.

The effects of infection with T. vivax in mid- or late pregnancy on food intake and utilization, liveweight changes, abortion rate and lamb growth rate were investigated in West African Dwarf ewes at Ibadan, Nigeria in 1990. Rate of livewight gain by ewes infected during mid-pregnancy (IMH) was 1...

This Report compares the efficacies of three anthelmintics, each belonging to one of the broad spectrum groups. It also identifies the genera of resistant worms through larval culture. The study was conducted on a commercial farm where anthelmintics had been used intensively. The results show cle...

The average flock size was 10 in 76 households. Flocks were established through purchase from fellow farmers. Sale for cash need was the farmers' main reason for keeping small ruminants. Periods of food deficit in the household were closely linked to the seasonality of cash need. producer househo...

The marketing system of small ruminants in coastal Kenya was studied through a case study in Kilifi and Kwale districts. Five channel levels were identified. 1) producers, 2) assemblers, 3) itinerant traders 4) retailers, and 5) consumers. Price discovery was by one-to-one bargaining at all the c...
