Quantity - The recommendation is to give a first feed of 3 litres or 10% of body weight. This should be followed by another similar feed within 12 hours of birth.
Quality - Good quality colostrum contains at least 50g/litre of IgG. Any colostrum containing less than 20g/litre should not be used
Quickly - It is important that calves receive their first colostrum feed as soon as possible after birth, ideally within 2 hours
