If colostrum is good quality, free of blood, serum, mastitis, feed 4 litres to the calf within 30 minutes of birth. If colostrum is poor quality use good quality colostrum that has been frozen or a good quality colostrum replacement product.
Feed another 2 litres of colostrum within 8 hours of birth. Feed calves 3 litres of colostrum two times per day at 12 hours intervals for 3 days and then switch to normal milk or milk replacer.
Do NOT feed milk from treated cows as it could leave residues.
