Extract

High genetic merit dairy cows were managed on four contrasting grassland based systems of milk production over a three-year period (Ferris et al., 2000). Each of the four systems were designed to incorporate a range of different approaches to increasing nutrient intakes. Key performance data from this study are presented in Table 1. The aim of this paper is to examine the effects of the four milk production systems on dairy cow fertility.
