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, milk-progesterone profiling was used to investigate the reproductive performance of two genotypes of dairy cow on two production systems (Pollott and Coffey, 2006). In this paper differences in fertility between genotypes and systems was investigated using energy balance (EB) and body condition score (CS) as explanatory factors.
