Extract

In many countries there has been an interest in including measures of liveweight and/or size in dairy cattle breeding goals, with the main aim of decreasing food costs. Whilst opinions about the right size of a dairy cow seem to differ among countries, it has been argued that because of the strong associations between liveweight, intake(-capacity) and condition score, the whole complex of these traits should be considered simultaneously (Veerkamp 1996). To do so, genetic parameters (and economic values) are required. Hence, the objective of this study is to estimate genetic parameters for yield, food intake, liveweight and condition score in first lactation heifers.
