Invited review: An evaluation of EFSA opinion on calf welfare from a nutritional and management perspective
2024
J.D. Quigley
ABSTRACT: In March 2023, the European Food Safety Authority published a Scientific Opinion on Calf Welfare. This opinion was prepared in response to a request from the European Commission to provide an independent view on the welfare of calves that reflected the most recent scientific knowledge. Data sources used to develop their recommendations included peer-reviewed studies, expert knowledge, and gray literature. The opinion considered specific scenarios and welfare consequences of specific management practices, including feeding fiber to calves raised for white veal and amount of cow-calf contact. The opinion suggested that calves should be fed specific quantities of forage NDF during the rearing cycle. Regarding separation of calves, the committee recommended that the calf should remain with the cow for a minimum of 24 h and then be housed with another calf. The committee further suggested that prolonged cow-calf contact should increasingly be implemented, due to benefits to both cow and calf to minimize stress of separation. The objective of this review is to assess the veracity of these recommendations and the scientific data that underpins them. This review will present literature to support the contention that, from a nutritional and management perspective, these recommendations may impair calf welfare by exposing calves to innutritious rations containing excess fiber and increasing their risk of morbidity and mortality due to poor colostrum intake and exposure to disease-causing pathogens. Alternative recommendations are made that may further the goal of calf welfare in the context of nutrition and housing.
