Nutrition and management of pre-weaned calves matters! Studies show early life health and nutrition are associated with improved lactation performance later in life.
The early life nutrition of calves has a direct impact on performance later in life. Calves need to be grown to reach 50% of their mature bodyweight in the first 12 months and 85% of their mature bodyweight at 24months of age. Colostrum is important in the first few hours with the key points being
Major factors affecting milk yield are the ability to supply the mammary gland with nutrients and the gland to produce milk. Achieving body size targets at first calving is critical: Loss of 300 kg of milk (1st lact) per -50kg body weight (BW) at calving, loss of 720 kg of milk (3 lact) per -50kg
