Extract

Selection is the main tool used by animal breeders to improve the performance of their stock. Despite large gains being made at industry level in the major dairy traits (Royal et al, 2000) very few reports exist for the results of experiments on persistent selection for dairy traits in a single herd, particularly with reference to the correlated effects on other dairy traits. This paper reports one such set of results between 1980 and 2005 from SAC’s Langhill herd, which has been under maximal selection for milk production during this period.
