UNIVERSITY PARK - To meet the goal of raising well-grown heifers that freshen by 24 months, a farmer cannot afford the set backs in growth that occur when heifers are left to fend for them selves in far-off, forgotten pastures, says a Penn State assistant professor of dairy and animal science. All too often, summer-time heifer management involves merely counting the heifers once a week to be sure they’re all there, according to A.J. Heinrichs. Pastures can be used very suc cessfully for heifers provided that they are checked daily and con cern is given towards feed, fly control and parasites. Heifers less than six months of age are usually better off to be kept in the bam, Heinrichs says. The digestive system of these young calves is not fully developed to handle high forage diets. These animals rely on getting most of their nutrients from grain. Also, Heinrichs adds, young heifers tend to suffer more from heat, com petition from other heifers and parasites. Dairy heifers that are 6- to 12- months-old can grow very suc cessfully on pasture provided that they are supplemented with four to six pounds of good quality, 16 to 18 percent dairy ration throughout the pasture season. Heifers that are over 12 months of age will do well on good quality pasture alone in early summer. However, it is important to realize that as pasture quality declines during mid to late summer, heifer growth rates also decline, From First Mow To Final Bale, KMN Makes Harvest-Time Easier.

Also some grain should be provided depen ding on the quality of these sup plemental forages. All heifers should have adequate shade and free access to good quality, clean water, Heinrichs adds. Ponds and streams which look good in spring may become stagnant or dried up in late summer. Fly and parasite problems can also stress pastured heifers to the extent that growth rates are reduced, Heinrichs says.

Animals that have not previously been exposed to parasites have little to no resistance to digestive tract parasites. Parasite eggs overwinter on pastures in the northeast. These eggs hatch into larvae under warm, moist conditions in spring weather. Heifers can become heavily parasitized by early to mid-summer. When this occurs, heifers grow slower because they are less feed efficient. They also may develop diarrhea causing them to become anemic. To avoid the build-up of parasites in heifers on pasture, Heinrich suggests rotating • Simple Design • Rugged Construction • Important Details That’s what Krone mowers and balers, Niemeyer tedders and rakes all from KMN have in common. And that’s what makes them easy to operate, amazingly efficient, and so dependable you’ll wonder how you ever got along without them. Lancaster Farming, Saturday, Juna 30,1084—A17 pastures and avoid overgrazing pastures. Worming at three and six weeks after turnout on pasture will greatly reduce the degree of parasitism, he adds. Pinkeye can also be a problem to heifers during the summer when on pasture. Fly control is im portant with this infection. Af fected heifers should be brought indoors for treatment and confined out of direct sunlight until the condition is cured, Heinrichs says. Further items that are often overlooked with heifers while on pasture are salt and minerals. Trace mineral salt should always be available to heifers on pasture. Be sure to check that selenium is dairymen. In the first of these dairymen should sign a producer certification for stating that calves to be slaughtered within the first three weeks of age have not received drugs. Such calves will be sold separately from uncertified calves. Calves without producer certificates will be subject to a new itensified residue-testing program.

The second item that should be available on a free-choice basis is a calcium phosphorus supplement (dical). Research has shown, Heinrichs says, that heifer diets that are low in phosphorus, which can occur on pasture, can delay the onset of estrus in these animals. Pasture, plus some good management, can provide a low cost labor efficient system for handling heifers over six months of age. Maintaining proper growth rates throughout the entire summer requires additional feed and effort but will help result in well-grown, healthy heifers Heinrichs concludes. and wet brewers’ grains to supply lower cost sources of energy and protein.
