Descripción

Trypanosomosis is a serious cause of reduction in productivity of cattle in tsetse-fly infested areas.Baoule and other local Taurine cattle breeds in BurkinaFaso are trypanotolerant. Zebuine cattle,which are also kept there are susceptible to trypanosomosis but bigger in bodysize. Farmers have continuously been inter crossing Baoule and Zebu animals to increase production and disease tolerance.The aim of this study was to compare levels of zebuine and taurine admixture in genomic regions potenti ally involved in trypanotolerance with background admixture of composites to identify differences in all elic frequencies of tolerant and non-tolerant animals.The study was conducted on 214animals(90Baoule,90Zebu,and34composites),genotyped with 25 micro satellites across the genome and with 155SNPs in 23 candidate regions.
