The Rural Voice, 1989-04, Page 16Keeping it in the Family Jerseys, those "little brown cows," are gaining in stature, both literally and figuratively. Not only are they bigger physically than they used to be, but they've been attracting the admiration of more dairymen. Jim and Tammy Sparling (right), a couple of young farmers, and their friend John Brand (left), who's building up a purebred herd of his own, reflect that renewed interest — as well as the traditional commitment of all dairymen. A s heirs of a Jersey herd that's been "in the family" for 50 years, it's appropriate that Jim and Tammy Sparling stress longevity as a breeding standard. "Some herds don't concentrate on longevity as much as they should — those going after super - high production," Jim says. "But unless they're a real good type they just don't last. For longevity you've got to have good sound udders. And that's what we breed for, really." He adds that he'd ship a poor type before a low producer. An average producer in the herd for five or six years, he reasons, makes more money than a high producer in the herd for one year. "I believe in cow families." Jim and Tammy, age 26 and 25 respectively, are planning for longevity in the Jersey business as well. They operate a 30 -cow Jersey herd on 100 acres near Varna in Huron County. Recent achievements include selling a young sire to the National Sire Proving Program at the United Breeders AI unit last year — Jaspar J R's Rambo — and a cow sold last summer who placed fifth at the All-American show in Louisville — Elmline Gemni Emma. They were also among the top ten producers in Huron County recognized by the Ontario Dairy Herd Improvement Corporation in 1987 and 1986 — 1988 awards have yet to be announced. Their most recent rolling herd average puts milk BCA at 168 (5,314 kg), fat at 153 (261 kg), and protein at 172 (206 kg). Average test is 5 per cent. The Sparlings' herd has been on ROP or DHI for 25 to 30 years. Jim and Tammy took the herd over in 1987 from Jim's mother and stepfather, Alec and Mary Ostrom, buying their own farm a few miles south of the home place. In turn, the Ostrom's had inherited the herd in 1967 from Tom Rathwell, Alec Ostrom's uncle. At 75 years of age, Tom Rathwell still looks after Jim's heifers; 14 THE RURAL VOICE
