Dairy Calf Management…Early care determines what you get for your bull calvesPart 2 in 5 part series
This 5 part series is provided by the Veal Quality Assurance Program. The series suggests ways of managing calves to increase the value of bull calves, but the techniques discussed will benefit heifer calves as well.
Calf care is a major area of lost economic opportunity in dairy production. Many producers do not realize that what is good for the heifer is good for the bull, and what is good for the bull calf is good for dairy herd profitability. Improved management of ALL calves on the farm will benefit the overall herd program, the milk market, the calf market and the producer’s farm income. How calves are managed in the first hours and days of life determines their potential as dairy replacement or veal grow-out.Today, 80% of the nation’s veal supply comes from dairy calves going to special fed veal growers where they are raised to about 20 weeks of age at a weight of 400 to 500 pounds. Only 14% of Holstein bull calves leave the dairy farm in the proper health and condition.
Industry and university studies indicate that calves which acquire a higher level of passive immunity in the first hours after birth are worth $20 to $25 more in their first four weeks of life, based on this single management factor. Not only are they healthier, less likely to die or incur treatment costs, and more likely to reach their potential - they also demonstrate faster growth and better gain, using less feed than their counterparts with low serum antibodies.
The quantity, quality and timing of colostrum feeding accomplishes far more than any vaccine or injection in protecting calf health and promoting long-term production and profitability. Four to six quarts of colostrum should be fed daily for at least the first three days of life. However, time is of the essence. The calf’s ability to absorb these antibodies from the lining of the small intestine directly into the bloodstream diminishes every hour as cell structures mature during the first 24 to 36 hours of life.
At the same time, calves are most vulnerable to ingested bacteria or viruses because these molecules are also absorbed easily into the bloodstream before gut closure. Whatever gets there first - antibodies or bacteria - are immediately absorbed by the calf to determine its future health and profit potential.First colostrum is the only antibody source for disease protection in newborn calves. It also contains vitamin E necessary for the four to six week process of immune system development. Colostrum is a source of important growth factors and hormones. The quality of the colostrum is determined by herd health, nutrition and immune status and the dry cow management program.
