Heifers are the future of your herd and your long-term success as a dairy producer. Heifer raising makes up 20-25% of the total cost of milk production. A successful pre-weaning calf program has been proven to increase first lactation milk yield by 1,000 lbs – 3,000 lbs. Genetic selection can account for 150 lbs-300 lbs greater milk production per lactation, but pre-weaning management can increase this 5-fold.
When calves are born, they start out as simple stomached animals. The change from one digestive method to another is a process that is called rumen development. The first two compartments make up one large fermentation vat, the third is an unusual-looking organ that absorbs water and minerals from digesta leaving the rumen, and the fourth is the true stomach that functions like the stomach of monogastric (people and pigs).
