While some may question the role of spaying in terms of animal welfare, I can assure them the welfare impacts and production losses associated with not controlling pregnancy in young females and old mature cows in extensive livestock systems far exceeds that of the spaying methodology. There are two primary techniques used for spaying cattle quickly and humanely; the Willis Dropped Ovary Technique (Willis), and the Webbing technique. Separating the ovary from the attachments using the Willis spay method in older cows significantly increases their risk of internal haemorrhaging due to the increased blood loss.
