History Many breeds that are considered purebreds are actually composites if you go back far enough in time. The understanding of genetics involved in crossing breeds of cattle has progressed enormously in the last 15 years. We now better understand the results of producing synthetic lines of cattle, which can be maintained on an . . . → Read More: Composite Cattle Breed History The Chianina (pronounced kee-a-nee-na) may well be one of the oldest breeds of cattle in existence. They were praised by the Georgic poets, Columella and Vergil, and were the models for Roman sculptures. The breed originated primarily in the west central part of Italy and was found in a wide variety of environmental . . . → Read More: Chianina Cattle Breed History The Boran developed in eastern Africa, more specifically the Borana plateau in southern Ethiopia. This area was where all the different breeds migrated through to their various destinations in Africa. The Boran developed into the dominant breed of eastern Africa and especially in Kenya, where the Kenyan Boran Cattle Breeders’ Society (BCBS) have . . . → Read More: Boran Cattle Breed History The breed originates from the the Aquitaine district in south west of France embracing the area of the Garonne valley and the Pyrenees. Three strains of cattle comprise the Blonde d’Aquitaine. The are the Garonnais strain, the Quercy, and the Blonde des Pyrenees. The Blonde d’Aquitaine trace to cattle that were . . . → Read More: Blonde d’Aquitaine Cattle Breed It is often argued that there is a larger genetic variation within a particular breed than there is between breeds. Results from the US Meat Animal Research Centre show that both between and within breed, genetic variations are large and important for most traits of economic importance. For example, Figure 1 shows that the . . . → Read More: Variation Within Crossbred Cattle The most commonly recognised benefit of crossbreeding is hybrid vigour or heterosis. This is the amount (expressed as a percentage) by which the crossbred progeny are better than the average of the two parent breeds. A word of warning: the performance of the progeny still depends largely on the performance of the parents. . . . → Read More: Benefits of Crossbreeding Beef Cattle |
