There are significant costs associated with reproductive inefficiency in pasture-based dairy herds. This study has quantified the economic effect of a number of key variables associated with reproductive inefficiency in a dairy herd and related them to 6-week calving rate for both cows and heifers. These variables include: increased culling costs, the(More)
Reproductive performance has an important effect on economic efficiency in dairy farms with short yearly periods of breeding. The individual factors affecting the outcome of an artificial insemina-tion have been extensively researched in many univariate models. In this study, these factors are analysed in combination to create a comprehensive multivariate(More)
Reproductive performance is important for the economic efficiency of pasture-based dairy farms. In these seasonal calving systems, a concise period of breeding is essential to ensure the alignment of peak grass availability with peak lactating cow energy demands. Trials and statistical analysis have identified the factors affecting overall reproductive(More)
