Extract

The ability of high-yielding modern dairy cows to perform in the range of systems found on UK dairy farms and to be profitable and sustainable needs investigating. As part of a project to study the robustness of such animals, milkprogesterone profiling was used to investigate the reproductive performance of two genotypes of dairy cow on two production systems. The use of milk progesterone profiles to give a detailed picture of oestrus cycle activity and fertility in dairy cows has been described by Royal et al. (2000).
