Dairy-beef farm farmers are encouraged to manage the transition of calves from milk to grass effectively to prevent summer scour syndrome, a condition that can lead to weight loss and death in calves. This syndrome is characterized by the sudden onset of scour, mouth ulceration, blindness, and death. To prevent it, farmers should ensure calves are properly weaned and confidently eating at least 2kg of concentrates and adequate roughage daily. For a week or two post-weaning, calves should be kept indoors and concentrates fed twice a day. High levels of roughage and fiber should be maintained in their diet at grass, and they should be introduced to stemmy, older grasses for a few weeks post-turnout. Concentrates with additives to aid rumination can also be used. In case of scour or setbacks, farmers are advised to consult their vet and consider taking a dung sample from the calves to rule out coccidiosis or heavy worm burden.
