Bainbridge Street Elizabethtown, Pa. 17022 THIS ONE SHAKES Van Dale 562 Shaker Feeder Versatility. That’s the “562." It's a feeder and bunk system all in one. It shakes a uniform feed mixture down the trough, provides its own feed bunk and has guard rails as standard equipment. The "562" is versatile in oper ation too. A variable speed drive, powered through a rugged 3 hp motor, allows you to feed fast or slow. The stainless steel trough is self-cleaning and enables you to build a feed bunk from 22 to 102 feet in length. Extends to any length by using a drive unit every 102 feet. And the unique shaking con cept means you can provide an even ration mixture for any type of feed—even baled hay. Dollar for dollar you won't find a more economical bunk-feeder combination. And, since there are no augers, chains or belts you'll find maintenance expenses are close to nothing. That’s the ‘'562”. A little money. A lot of versatile bunk. Non-Stop Feeding VAN PALE Box 337 • Long Lake, Minnesota THISHD IS HLL BUNK THIS ONE TRAVELS Van DaIeSCFI4OO&SCC 1400 Chain Feeder and Conveyor Workhorse. That’s the Van Dale 1400 Feeder System. It delivers up to 40 tons an hour of hard-to-feed materials. And keeps them uni formly mixed the entire length of the bunk. The “1400” system is designed especially for large operations. The entire unit can be suspended or floor mounted with speed and low installation costs through Van Dale's exclusive “snap-together” construction. All galvanized metal construc tion means less upkeep and maintenance. The motor and drive unit remain stationary and fully shielded for maximum safety and minimum repairs. Compare any large capacity feeder system with Van Dale. You’ll choose the workhorse “1400". Ask Your Van Dale Dealer About The New Agri-Leasing Program. Researchers Report on Poultry - Extremely high or low levels of calcium and phosphorous fed to developing pullets might ad versely affect egg production or quality, according to Dr. E. C. Naber, chairman of the Poultry Science Department at Ohio State University, speaking in Washington, D.C., at the 20th Annual Pfizer Research Con ference. Naber said calcium requirements of the egg-laying, production-type chicken seem to vary from 2 % to 3V 2 per cent of the diet. Higher calcium levels may hurt feed consumption and egg production rates depending on their source. Some dolomitic limestones have been shown to be satisfactory for laying hens although excessive magnesium can still be a problem. Naber noted that poultry nutrition made strides toward becoming a more exact science in 1971. New data have more precisely defined chicken and turkey requirements for several nutrients. He cited the following efforts in particular: - Protein and amino add needs CALEB M. WENGER Drumore Center, RDI Quarryville, Pa. Phone 548-2116 of growing chicks and turkey poults were studied. - The replacement value of cystine for methionine and the total sulfur amino acid requirements were reevaluated. - The need for proline as an essential amino acid for chick growth was confirmed. - The lysine and total sulfur amino acid requirement of the poult were refined. Vitamin research indicated that beta-carotene supports growth as well as vitamin A, but does not permit liver storage of the vitamin based on its potency for growth, according to Dr. Naber. He mentioned conflicting studies about the benefits of vitamin D 3. Turkey breeders did not respond to a biotin sup plement nor did developing pullets or layers respond to choline supplementation. Rapeseed meal, castor bean meal, dried yeast sludge and dogfish meals were among the unusual products studied for possible feed use. Other studies THIS ONE AUGERS Safety covers not shown Van Dale Mammoth 14 Multi-feeder Efficiency. That’s the Van Dale Ml 4. It can make your diversified live stock operation a single system. Because the Ml 4 can feed up to four different lots at one feeding. And, each lot can receive its own special ration. The Ml 4 has a massive 14' trough and is fed by a bearing suspended 12' auger. It can pro vide you with up to 200 feet of feeding and will dump rations on either the left or right hand side. Or it can carry feed all the way to the end of the trough before dumping. For mixing concentrated addi tives, the Ml 4 auger action is unequaled. It provides consist ently uniform rations all along the trough. Selective feeding of different feed lots. High capacity feed line. Uniform feed additive mixing. That’s the Van Dale Ml 4. Lancaster Farming, Saturday. May 27,1972 Dietary Studies have shown that processing full fat soybeans by infrared heating and extrusion and their use in growing rations for chicks are promising alternates to con ventional soybean processing. Expansion-extrusion of grains did not affect growth of the chick. Dr. Naber also pointed out that studies on natural and chemical pigmentation sources confirmed that there are a number of satisfactory products for coloration of skin and egg yolk. Dr. Naber discussed studies of contamination of feedstuffs with micotoxins. FUSARlUM contaminated corn adversely affected egg shell quality. Developments in other studies showed that the protein, lipid and antibiotic content of the diet affords some protection against aflatoxin to chicks. BABCOCK FARMS, INC Mobile Laboratory Is Seeking New Ozone Data The ozone layer, the gas that absorbs the sun’s deadly radiation high in the sky and makes life possible on eaith, is being studied bj the Na tional Aeronautics and Space Administration (NASA).
