C26—Lancaster Farming, Saturday, July 5,1980 NUTELY, N. J. Vitamin A can help cattlemen realize good production efficiencies, says Hoffmann-Laßoche Inc. This vitamin is essential to help the animal’s body build various defenses against infectious disease and stress. According to research conducted at the University of Florida, adding sup plemental vitamin A to cattle rations, presumed to Named assistant extension agent SCRANTON - Ellen R. Katz has been named to Penn State’s Cooperative Extension Service staff as assistant Extension agent serving as an area farm and home management agent in the Northeast Extension Region. Thomas B. King, Penn State associate dean for extension, who announced the appointment said that Ms. Katz already has begun her duties. She is responsible for planning and conducting educational programs focusing on farm business management and family financial planning in the DID YOU EVER SEE aTRIEaFTERA^/ msnwf CUSTOM BUILT HAY WAGONS OUTSIDE CALF HUTCHES With Metal Roofs And Feeders • Painted and Creosoted FOR ADDITIONAL INFORMATION WRITE OR CALL STOUZfUS WOODWORK Should you supplement vitamin A for improved cattle production? have adequate increased rate of weight gam of stressed fattening steers, compared to stressed cattle receiving no vitamin A fortification. In another university study, researchers studied vitamin A metabolism in cattle subjected to hot weather stress.

A native of New York City, Ms. Katz graduated from Cornell University with the bachelor of science degree in Agricultural Economics. At Cornell she was a member of the Collegiate Chapter of the Future Farmers of America and the Ag POC-Student Positive Action Council.

In additional studies, cattle without shade lost two and half times as much of their vitamin A liver stores as cattle with access to shade. While vitamin A does not occur in feedstuffs of vegetable origin, these feedstuffs do contain carotenes that can be con verted to vitamin A activity in the intestinal wall of the animal. But the efficiency of conversion depends on the amount of carotenes con sumed and the types of carotenes supplied by feedstuffs. Of the dry roughages commonly used in beef cattle rations, dehydrated alfalfa meal has very high carotene content, averaging 28 milligrams per pound, while non-legume hay has very low carotene content, averaging 6 milligrams per pound. However, cattle do not efficiently convert carotene to vitamin A activity. Rats generally convert 1 milligram of beta-carotene to 1,667 I.U of vitamin \ activity, while cattle nor mally convert 1 milligram of beta-carotene to 400 I.U of vitamin A activity Vitamin A should be supplemented in cattle rations to offset variations in carotene content of feed stuffs, says Hoffman- Laßoche These variations are due to lower carotene levels in moldy and light weight com, compared to sound com, and carotene losses occurring m feed- stuffs during harvesting, processing and storage, they claim. Supplemental vitamin A should also be fed to com pensate for variations m the ability of the animal to convert carotene to vitamin A activity. Conversion is influenced by breed, nitrate and nitrite intake, intestinal parasites, stress, changes m thyroid function, biological variations among cattle, and phosphorus and protein levels in the ration. Thus, vitamin A sup plementation of cattle rations is important to offset factors that cut vitamin A availability and utilization and, thus, prevent deficiency and allow optimum per formance.
