Extract

Poor reproductive performance is a major problem on dairy farms throughout the United Kingdom and has been identified as the single most important problem in two recent farm surveys in Northern Ireland (AgriSearch, personal communication). The decline in reproductive performance is often attributed to increased genetic merit for milk production, but is also influenced by a large number of factors including changes in management practices and nutritional factors. The aim of this study was to examine reproductive performance in a range of dairy herds in Northern Ireland to identify the key factors influencing reproductive performance at farm level. This paper presents the findings of three years of study.
