GI nematodes are most commonly controlled by chemotherapy. Anthelmintic efficacy is decreasing as drug resistance becomes widespread and other approaches are needed. Knowledge of protective immunity against GI parasites is important for the development of vaccine strategies. Success in this field...

Investigates the effect of increasing dietary fibre in roughage diet on movement of trace elements in the digestive tract of sheeSummarises the composition of experimental diets. Includes data on nutrient concentration, digestibility, absorbtion and secretion.

Linear-multilevel models (LMM) are mixed-effects models in which several levels of grouping may be specified (village, herd, animal, ...). This study highlighted the usefulness of graphical methods in their analysis through: (1) the choice of the fixed and random effects and their structure, (2) ...

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.


Reynolds, L.Baker, R.L.Sherington, J.Njubi, D.[Resistance to gastro-intestinal parasites in Dorper and Red Maasai-Dorper crossbred sheep]Resistance to gastro-intestinal parasites in Dorper and Red Maasai-Dorper crossbred sheep

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...


Baker, R.L.Rege, J.E.O.Tembely, S.Mukasa-Mugerwa, E.Anindo, D.O.Mwamachi, D.M.Thorpe, W.R.Lahlou-Kassi, A.[Genetic resistance to gastrointestinal nematode parasites in some indigenous breeds of sheep and goats in East Africa]Genetic resistance to gastrointestinal nematode parasites in some indigenous breeds of sheep and goats in East Africa
Autor: Baker, R.L.

The evidence for both between-and within-breed genetic variation for resistance to gastrointestinal (GI) nematode parasites is reviewed. It is concluded that much of the published research on breed characterisation for resistance suffers from poor experimental design. Prior to the initiation of a...

A review of genetic resistance to gastrointestinal nematode parasites in sheep and goats in the tropics and evidence for resistance in some sheep and goat breeds in sub-humid coastal Kenya]Genetic resistance to endoparasites in sheep and goats. A review of genetic resistance to gastrointestinal nematode parasites in sheep and goats in the tropics and evidence for resistance in some sheep and goat breeds in sub-humid coastal Kenya

Two experiments were conducted to investigate the relationships between work and intake and digestion of food by draught oxen given millet stover. In the first experiment, intake of millet stover, water intake, live weight, plasma concentrations of triiodothyronine, thyroxine and urea-nitrogen we...


Fall, AbdouPearson, R.A.Lawrence, P.R.Fernández Rivera, S.[Nutrition of draught oxen in semi-arid West Africa. 2. Effect of work on intake, apparent digestibility and rate of passage of food through the gastro-intestinal tract in draught oxen given crop residues]Nutrition of draught oxen in semi-arid West Africa. 2. Effect of work on intake, apparent digestibility and rate of passage of food through the gastro-intestinal tract in draught oxen given crop residues

Small-scale rural farmers cannot complete with the large-scale, peri-urban, and vertically integrated systems using the same type of feed resources (i.e. imported grain cereals and protein sources), animal genotypes and facilities. In order to succeed, these farmers need to develop alternative pi...

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...

A dynamic human gastrointestinal (GI) model was used to digest cooked tubers from purple-fleshed Amachi and Leona potato cultivars to study anthocyanin biotransformation in the stomach, small intestine and colonic vessels. Colonic Caco-2 cancer cells and non-tumorigenic colonic CCD-112CoN cells w...
