Monitoring the health and welfare of dairy youngstock. Part 2: replacement heifers in the postweaned period

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Background : Heifer rearing generates substantial on‐farm data, which is frequently under used by both farmers and veterinary surgeons. Effective data analysis is a critical component of cattle practice, enhancing youngstock rearing efficiency. When combined with clear communication, it facilitates on‐farm improvements and strengthens the veterinary–farmer relationship. Aim of the article : This is the second in a two‐part series reviewing an evidence‐based, practical approach to monitoring the performance, health and welfare of dairy youngstock from birth to first lactation. Using case‐based examples, it guides farm clinicians in applying key performance indicators to improve rearing efficiency. This article focuses on the postweaning period through to first calving, centring on data around daily liveweight gain, fertility and economics, and how to tackle issues on farm.
