Dl2-Lmcaster Farming Saturday, March 9,1985 Cottonseed found desirable for dairy cows Dr. George F.W. Haenlein Extension Dairy Specialist University of Delaware NEWARK, Del. - Whole cot tonseed recently became available in the Northeast. Should you buy it as part of your dairy feeding program, and if so, under which circumstances? Only sunflower seed equals whole cottonseed in its triple high values of energy-fat, protein and fiber. This makes either seed very attractive as a feed for early lactation dairy cows. Recent analyses show whole cottonseed has an average 21 percent crude protein in the dry matter, 18 percent fat, 29 percent crude fiber Speaker chosen for convention EPHRATA Brenda L. Dawson, Director of Member Services for The Fertilizer In stitute in Washington, D.C. will be one of the three guest speakers to be featured at Pennag Industries’ Annual Convention at the Philadelphia Adam’s Mark Hotel, October 6-8. Ms. Dawson will address the convention on the topic of: “Environmental Issues and the Fertilizer Industry.” Ms. Dawson joined The Fer tilizer Institute in August 1983.

Based on its combined energy and protein content, the dollar value of whole cottonseed would be $166 per ton, if com is $3 per bushel and soybean oil meal (SBOM) $240 per ton. At the same SBOM price but a cheaper com price of $2.50, whole cottonseed shouldn’t cost more than $149 to be comparable. Additional “opportunity” prices over a wide range of com and SBOM prices are available from my office. proposals which might impact the fertilizer industry in the areas of resource management and product quality. Also within these areas, she is responsible for representing and informing the industry of issues such as fertilizer use, water quality, fertilizer laws, and methods of fertilizer analyses. Dawson received her bachelor’s degree in biology, and her master’s degree in environmental science and engineering from Virginia Polytechnic Institute and State University. PLACE (Type of building) County Recent research in several herds with large numbers of high milking dairy cows has shown that feeding whole cottonseed stimulates and supports even high milk production. Substituting usual dairy grain mixes with up to 20 percent whole cottonseed resulted in increased milk per cow even when the energy contents were equal. Milk fat percentages were slightly increased, too. Digestive use of whole dairy rations was shown to improve in protein, fat and total energy, when increasing amounts of whole cottonseed were added. In a comprehensive study, in volving 55 California dairy herds to determine any possible side ef fects, when the recommended upper level of as much as 6% pounds whole cottonseed per cow was fed daily, no negative effects were observed in frequency of displaced abomasum, ketosis, milk fever, retained placenta or contents of milk fat, protein and solids-not-fat. Even 14 pounds per cow daily had only positive effects in milk and milk fat production (an increase from 68 to 72 pounds of (Date) WeSptctollnln AarliK w* Have Pote» in Myerstown, PA 17067 stock 25-. 30.35 * 45' Rhone: 717-866-7544 ATTENTION FARMERS & LIVESTOCK HAULERS: ALUMINUM EBY GOOSENECK CONSIDER THE FEATURES OF AN TRAILERS, Standard Specifications; EBY ALL-ALUMINUM TRAILER LENGTHS AVAILABLE: 14’to 28’ (longer lengths available as option) WIDTHS; 96” Standard -102” Optional HEIGHT: 6’6” Standard-7’6” Optional A versatile, lightweight, Eby aluminum stock trailer is built to provide years of maintenance free service.

Calves also showed improved growth rates when fed whole cottonseed at 25 percent of the concentrate ration. Cottonseed is toxic to swine and poultry, but not normally to ruminants, because a yellow pigment called “gossypol” in cottonseed (about 1 percent) can cause depressed blood hemoglobin and increased red blood cell fragility. Gossypol has been identified in blood plasma and liver, but not in milk in ex periments feeding as much as 22 pounds of cottonseed per day to cows. However, aflatoxin 320 King St. ALUMINUM GOOSENECK TRAILERS LUMIN ED detected in some cottonseed samples, which could endanger the health of cows and humans, since it is excreted in milk. In such cases, aromoniation of cottonseed (1.5 percent for 21 days) has suc cessfully reduced aflatoxin con tents to negligible levels. Nor mally, aflatoxin occurs no more often in cottonseed than it does in com or soybeans. Feeding cottonseed, in my opinion, is indicated-even desirable-when: •The price is right, *high milking cows need extra feed energy support, and ‘cows testing low milkfat percentages and im has been provement. ■■■■■■ ■ ■ ■ ■ n i ■ Machine Work a { Welding 1 .
