Behnke, J.Iraqi, F.A.Menge, D.Lowe, A.Teale, A.J.Gibson, P.J.Baker, R.L.Wakelin, D.[Mapping chromosomal regions controlling resistance to gastro-intestinal worms in mice]Mapping chromosomal regions controlling resistance to gastro-intestinal worms in mice

A total of 1443 records of preweaning traits of calves in a dairy herd in coastal lowland Kenya were used to estimate crossbreeding parameters in a regression analysis. In this herd, the Ayrshire (A), Brown Swiss (B) and Sahiwal (S) breeds have been used in a 3-breed rotation crossbreeding system...


Kahi, A.K.Thorpe, W.R.Baker, R.L.[Parameter estimates for additive breed genetic and heterotic effects for preweaning traits of dairy calves in coastal lowland Kenya]Parameter estimates for additive breed genetic and heterotic effects for preweaning traits of dairy calves in coastal lowland Kenya

Genome-wide quantitative trait locus (QTL) mapping was used to evaluate the genetic basis of resistance to Helgmosomides polygyrus in an F2 cross of SWR and CBA mouse strains that are resistant and susceptible, respectively, to infection. 25 significant QTL affecting at least one of the resistanc...


Menge, D.M.Behnke, J.M.Iraqi, F.A.Lowe, A.Teale, A.J.Gibson, John P.Wakelin, D.Baker, R.L.[Quantitative trait loci for resistance to gastro-intestinal nematode infections in mice]Quantitative trait loci for resistance to gastro-intestinal nematode infections in mice

The effect of genotype, lactation and season on the periparturient rise in faecal egg counts in Ethiopian highland ewes: preliminary observations. A study was carried out at the International Livestock Research Institute (ILRI) Debre Berhan Research Station Between May 1992 and January 1995 to co...


Tembely, S.Lahlou-Kassi, A.Rege, J.E.O.Mukasa-Mugerwa, E.Anindo, D.O.Baker, R.L.[The effect of genotype, lactation and season on the periparturient rise in faecal egg counts in Ethiopian highland ewes: preliminary observations]The effect of genotype, lactation and season on the periparturient rise in faecal egg counts in Ethiopian highland ewes: preliminary observations
Kosgey, I.S.Werf, J.H.J. van derKinghorn, B.P.Arendonk, Johan A.M. vanBaker, R.L.[Theoretical assessment of alternative pure-breeding schemes for sheep meat in the tropics]Theoretical assessment of alternative pure-breeding schemes for sheep meat in the tropics

The effect of dietary protein supplementation on the resistance of lambs to endoparasites was examined in Horro and Menz lambs artificially infected with Haemonchus contortus. The experimental design involved 2 breeds, 2 infection treatments (infected Vs non-infected) and 3 nutrition treatments. ...

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...


Mwamachi, D.M.Audho, James O.Magadi, M.Reynolds, L.Baker, R.L.[Evidence for multiple anthelmintic resistance of gastrointestinal nematodes in sheep in coastal Kenya]Evidence for multiple anthelmintic resistance of gastrointestinal nematodes in sheep in coastal Kenya

Sustainable livestock improvement cannot be guaranteed for most tropical areas of the world without utilization of the evolutionary adaptation of the indigenous livestock breeds. The paper summarizes the adaptive traits of indigenous tropical breeds, presents a case for their evaluation and discu...
