Health status, production and reproduction performance in cattle herds as influenced by management

Abstract

The overall trend of the reproduction performance is a reduction since at least 20 years. In Belgium, the pregnancy rate at artificial insemination decreases about 1% per year (Opsomer et al, 2006). To obtain good reproduction performance, many requisite factors are necessary. Health status, nutritional status or production level are some well-known examples. Many studies review these factors and their impact on the reproduction performance. The aim of this work was to describe the impact of health status, production and management on the reproduction performance in Walloon farms.
