16—Lancaster* Farming, Saturday, September 2, 1961 Cow's Preference Is Important Says Professor A la carle or come and get it’ Which will it be when feeding sudan grass to your dairy cows’ ■ Resear ch findings support the come and get it system, says Dr. George Haenlem of the Uni. of Delaware. In studies conducted at the university it has been proven that cows on pasture consume more forage in a day than those fed green Trefoil Needs Plenty Of Sun Birdsfoot trefoil, one of the farmer’s best forage crops, is sensitive to shad ing by comnanion crops and weeds, studies at the Penn State University indicate Tests by Guy W McKee, research agronomist, show that birdsfoot trefoil needs 25 per cent of full daylight to survive and 50 per cent to produce nodules Dr, Mc- Kee says this partially ex plains why many plantings of trefoil start slowly and often are thin or fail. Light under a dense grow th of weeds and companion crop may be no more than 6 per cent of full daylight, Dr McKee explains The trefoils were compar ed with Pennscott red clov er and Vernal alfalfa. In all cases the trefoils were re duced more by shading than were the clover and alfalfa. Pennscott and Vernal grew and produced functional no dules with half the amount of light needed by the tre foil Under a canopy of Clin ton oats, leaf areas of birds foot trefoil were reduced by half Under the same oat canopy, seedlings of Penn scott red clover and Vernal alfalfa had as great a leaf area per plant as seedlings grown in the open. Shading and competition from a companion crop also depress tire top and height growth of trefoil seedlings, the studies indicate. Countians Win At Hay Show Two Lancaster county far mers, Mahlon H Shenk, of Holtwood R 2, and Galen W. Crouse, S 4 evens Rl, won the chamtvonships at the South east Penna Hay Show, Aug 24 at Hershey, both with la ter (than first) cuttings of al falfa. Another county farmer, John S Shenk 11, Willow Street Rl, won a blue ribbon in the first cutting of mixed hay class Mahlon Shenk won in the field cured division and took the grand championship Crouse topped the heat cured division and was runner up to Shenk for top show hon ors John Shenk also took a fifth placing m mixed hay with over half grass Farmers from eleven coun ties Chester, Montgomery, Franklin, Berks, Adams, Cumberland Schuylkill Dauphin, Lebanon, Lancaster and York entered 173 samples, 128 of them field cured, 45 heat treated W.

Also, they select the more digestible parts of the plant. The average digestible in take of a grazing cow is more than five pounds a day grater than one which is hand fed. This additional consumption will provide enough nutrients to supply 16 more pounds of four per cent milk daily, Haenlein says When you add to this the cost of harvesting green chop it makes the old fash ioned system of letting the cow be her own chopper look pretty good, despite some waste when the cows tramp around the field. With green chopping, zero grazing or bunk feeding which are all names for the same process you feed the cow the nutritious and fibr ous portion of the plant in discriminately. The cow is filled with a lot of ballast that will not produce enou gh milk. It is true that cows generally relish green chop Successful Dairyman Says: "Farm Bureau's DARI-PAK Program Right For Me" J.

With green, chop you have to supple ment more gram to make up the difference in forage qua lity than with grazing. The cows have proven in our studies with sudan grass ov er a period* of six years, that they understand how to select the more nutritious plant parts. The part that is being wasted is of little or no value from a nutrition and production standpoint. It will take some addition al feed intake to support the grazing cows. Their maintenance requirements are slightly higher than tho se that stay in the barnyard and are fed cut forage. It has been shown in other experiments, that the diffe rence m selective consump tion more than makes up for the work required by the cow to go and get it It’s hard to beat nature’s way of harvesting forage crops.
