(ContlnuMl from Pago C 2) What Really Matters? Use high calcium limestone. And we have plenty of it in the Northeast. If you’re not sure what you’re getting, the suppliers can provide specification sheets on all of their products. There should be a listing for calcium (or calcium carbonate) and magnesium (or magnesium carbonate). Shoot for a calcium level of least 38 percent (equivalent to 95 per cent calcium carbonate). And try to buy limestone that has no more than 1 percent magnesium. This is equivalent to 3.S percent magne sium carbonate (MgC0 3 ) or 1.6 percent Magnesium Oxide (MgO). What if you’re buying complete feed or a vitamin mineral premix? Not to worry, the high calcium limestone is already there. Summary 1. The most important aspect of limestone is the calcium content. Buy a product that has at least 38 percent calcium. Products with less than 38 percent calcium will have increasing amounts of mag nesium, which limits the digesti bility of calcium. 2. Besfdes magnesium, limes tone contains a lot of impurities. The major elements are aluminum, and iron. The aluminum is unavail able to the pig, and the iron is only partly available, so neither of these contaminants presents any reason for concern. 3. Ideal particle size of the limestone is in the 300-1,000 FARMING FOR THE FUTURE wilh * A new AERWAY can be your ticket to INCREASED PROFITS and help you comply to your conservation plan. /Mr wa ran tha. „ »her» m had hanaalad own adaga. . j than •Pf»«l batwaan 4,000-S.OQp gUtom ol liquid ™™» par acra and dMad (m nod M to pm* PJMtofimal 1 gralna.

The notion that a premix or any other product is nutritionally superior because it contains mid western limestone (and not north eastern limestone), is silly. REFERENCES Axe, Diik. 1988.

SWINE PRODUCTION COURSE OPEN TO PRODUCERS This fall, producers may attend undergraduate lectures and labor- i spring, I used the Aer-Way Implement and chain harrow on my rolling pastureland. This ' open up the ground to get water into the grasslands. At the same time I pulled the Aer Way chain harrow to scatter the cattle manure around. Sven after the dry summer we had, I noticed that the Aer*Wayed ground held the moisture better and we got thicker and taller regrowth where we ran the machine. Dr. Rex WMiehn D.V.M..

Under the bright lights of the show ring at the Perry County Fair, Erin Benner of Millerstown led her heavyweight market steer to the championship. Selected by judge Bob Mikesell of McAlisterville, the 1.321-pound steer topped a mark et show with a record number of entries. The steer also was named FFA champion steer. The reserve champion market steer honors went to a middle weight Limousin-Charoliar cross exhibited by Grant Finkenbinder of Duncannon. The steer also was named 4-H champion steer.
