DMancastar Fanning Saturday, June 11, 1988 By Joyce Bupp York Co. Correspondent KRALLTOWN (York) Twelve years ago, Ralph McGre gor made a management decision he would avoid even telling other dairy producers about for the next several years. The York County dairyman walked to his bam office supplies cabinet, pitched out every tube and bottle of mastitis treatment, and pledged a firm “No” to using anti biotics on mammary system flareups. Instead, McGregor vowed a new approach to udder health in his 102-head milking herd of regis tered Holsteins. Rather than “shoot ’em up” when swelling and flaki ness infected udders, McGregor set out to test a more positive man agement move. Underpinning this tactic was a belief that, relieved of as much environmental and man made stress as is reasonably possi ble, the dairy cow can successfully battle invading mastitic pathogens without antibiotics. Attending the 1976 National Mastitis Council meeting in Louis ville, Kentucky, McGregor seri ously weighed the message of a eg ry generally less stressed. Supplies such Si jrtox, udder balms, fly bait and new inflations now fill office cabinets that once housed an array of mastitis-treatment antibiotics.' Mastitis Drugs: Just Say No speaker on the anatomy of the mammary system. Everything about the cow’s mammary system is designed to safely put milk out the teatand, including microscopic hairs inside the teat canal for the glands’ protection. “How much harm do we do if we put something in there that reconstructs the system, allowing outside organisms in?” was the question that haunted McGregor. Having worked with—and treated cows since his childhood, the Kralltown dairyman figured he had seen no real long-term improvement in the problem of mastitis. Maybe there was a better approach. DHIA herd average at Mcßal Dairy that year on the 102 cows was 15,370 milk and 566 fat Cull rate, based on statistical data McGregor has compiled for his management comparisons, was at 22 percent. Highest somatic cell count that year was at 650,000. Aware that his approach was veering from the norm, McGregor kept his mastitis approach pretty much to himself. Over the next six years, both herd numbers and herd average steadily climbed. By the end of 1983 test year, DHIA average came in at 151 head with a 18,635 milk and 668 fat record. Somatic cell counts ranged that year from a low 0f207,000 to a high of 356,000. Cull rate was still at 22 percent, but had fluctuated from 19 percent in 1977 to 27 per cent in 1979, responsive in part to cull-cow prices. This continuing upward trend shows no signs of reversing. The current milking herd numbers 230 head, with an April DHIA Rolling Herd Average of 19,530 milk, 724 fat, with a SCC averaging 149,000. Cull rate for 1987 was 21 percent, up slightly from 17 percent rate in both 1985 and 1986. “We do not need the crutches of mastitis medicine,” McGregor firmly insistetd. Controlling Stress Instead, proper husbandry and gentle handling of the dairy herd, with emphasis on minimizing con trollable stress factors, are the basis of McGregor’s mastitis management techniques. And, ani mals with a chronic health, breed ing, hard milk-out or mastitic prone tendency are soon culled. “Why keep a problem cow to milk and breed from?” he wonders. McGregor emphasizes that his milking-housing facility is not new, nor are all conditiops of the operations “textbook” ideal. The 16-year-old parlor is a double-four herringbone, which takes several hours for each milking to handle 230 head. While milking is a one person chore, seveq different fami ly members and employees help as needed in the parlor. And, herd size now outstrips freestall capaci ty, by about 25 percent. “Our cows are used to anything and anybody,” McGregor adds with grin. And, he quickly noted, they do occasionally flare up with mastitis. But, in the last six months, he and herdsman, Don Dyer, can tally only two cases of mastitis. One was an older herd member, which tramped a teat, and the other a “hot bug” with swelling. Both get the routine Mcßal treatment for flareups; hand strip ping, at each milking. No tubes. No shots. “If everything else is right for a cow, overcoming a mastitis infec tion should be like a healthy person who can fight off a cold naturally with a little lime. You can fine tune nutrition, the milking system, keep the cows clean, and do what you can to naturally help her do so.” That begins at Mcßal Farms with the handling of the cow and McGregor’s adherence to the phi losophy that “every cow is a lady and should be treated as such.” Jumpy, nervous cows arc more stressed, generally favoring masti tis and higher SCC’s. “You’ve got to keep a cow trust ing you, by staying cool, calm and collected when working with her,” McGregor teaches employees. “That means you don’t hoop and holler to drive cows in a parlor or when moving them to different locations.” Adequate facilities, such as proper hcadgatcs, alleyways and loading chutes add to cattle handling ease. McGregor houses heifer-age groups at several nearby facilities, and animals arc moved to as many as four locations from weaning to freshening, making smooth handling techniques an “My tomahawk .

Sand As Bedding Soon after the NMC conference, a vet recommended to McGregor the use of sand for frcestall bed ding, over more conventional materials. Sand drains well, and its wttgm cuts oown ojrmc idsses from cow movement. When fresh sand is added, about every six weeks, a dusting of hydrated lime serves as an additional bacterial deterrent. An advocate of low milking lines to avoid the system ineffi ciencies of lifting milk, McGregor had lowered parlor lines in 1972. The two-inch lines installed then are still in use, though considered borderline efficient by some Note: Joyce explained that preparing for the Dairy Month issue became slightly unbearable at times.

She and her husband, Leroy operate Bupplynn Farms, near Loganvile, with 200 head of milking registered Holsteins. Their children Patty, 18, and Richard, 15, are actively in volved in the family farm. Joyce is a board member of the Middle Atlantic Divisional Dairyman, Inc., and the Dairy Council of the Upper Chesapeake Bay. She is co coach of the county’s Junior Holstein and 4-H Dairy Bowl milking-system experts. All water used for udder clean ing, and in the equipment washup, is run through a softener. Soften ing of the naturally hard water seems to aid in keeping teat ends soft and pliable, plus perhaps ease cracking and chapping of workers’ hands, where rough skin could har ddt ana spreaamasnnc oaciena. Inflations are regularly changed every 1,000 milkings, since worn and cracked rubber in the linen will also harbor mastitic pathogens. Only minimal water, a mere handful to wet the teats, is used in pre-milking preparation. “Many people wash udders like they’re putting out a fire,” says (Turn to Pago D 4) teams. The Bupps are involved in the Holstein Association, 4-H and dairy promotion activities. Holstein News, Holstein World and Hoard’s Dairyman are some of the publications that have printed Joyce’s work. She received an award from Women in Communications for her column, On Being a Farm Wife. One of her Lancaster Farming articles also placed third in a competition hosted by Penn-Ag Industries. However, Joyce notes, “The greatest honors I have are my kids and my Dairy Bowl Kids.”
