BACKGROUND Diversity patterns of livestock species are informative to the history of agriculture and indicate uniqueness of breeds as relevant for conservation. So far, most studies on cattle have focused on mitochondrial and autosomal DNA variation. Previous studies of Y-chromosomal variation, with limited breed panels, identified two Bos taurus (taurine) haplogroups (Y1 and Y2; both composed ...

Brazilian dairy Gir (Bos indicus) cattle are a tropical, well-adapted breed, for which no information on the major histocompatibility complex (MHC) is presently available. The second exon of the bovine lymphocyte antigen (BoLA-DRB3) was amplified by polymerase chain reaction (PCR) of DNA samples from 28 Brazilian dairy Gir cows. Two experimental genotyping approaches were used: direct sequencin...

Introduction Kenya has one of the most successful dairy industries in sub-Saharan Africa based on some 3 million cattle of mostly high grade Bos taurus dairy breeds and a relatively advanced milk marketing infrastructure. The main breeds for dairy production are Friesian, Guernsey, Ayrshire and their crosses with the local East African Zebu (EAZ). The EAZ population is estimated at about 10 mil...
