D2-Lancaster Farming Saturday, February 1,1986 PDA urges strict bio-security measures HARRISBURG - State Agriculture officials are urging Pennsylvania’s $450 million poultry industry to observe biosecurity and continue strict sanitation measures to avoid unintentional spread of avian influenza. “Studies conducted by state and federal epidemiologists indicate that live bird haulers operating in interstate commerce may have been responsible for the rein troduction of avian influenza into Pennsylvania,” said state Agriculture Secretary Richard E. Grubb. Dr. Van Buskrik, director of the Toll-free flu hotline announced HARRISBURG - State Agriculture Secretary Richard E. Grubb has announced a toll-free number is available to address farmers’ concerns over the outbreak of avian influenza in central Penn sylvania. Farmers and processors requesting information may call 1-800-932- 0904. The number will be manned from 8 a.m. to 4 p.m. Information concerning specific marketing questions for processors, buyers, brokers and retailers will also be addressed. “Use of this number can facilitate the efficient, timely flow of in formation,” said Grubb. “We are committed to utilizing state resources to quickly control the outbreak and to protect the state’s poultry industry,” he added. Delaware poultry auctions ordered DOVER, Del. - Delaware Agriculture Secretary William B. Chandler, Jr. and State Veterinarian Dr. H. Wesley Towers, Jr. have ordered poultry auctions in Delaware to cease sales in light of recent avian in fluenza (AI) outbreaks in Penn sylvania. In making the announcement, Dr. Towers said the decision to NPPC to survey pork producers DES MOINES, lowa - The National Pork Producers Council has begun working with the USDA Agricultural Marketing Service (AMS) in formulating a final order that will implement the new 100 percent Pork Producer Investment Plan recently signed into law by President Reagan. A time table for implementation of the plan is under discussion, and the AMS staff has expressed its intent to respond as nearly as possible to producer desires within tiie framework of the new law. The best present estimate is that the new checkoff plan will be im plemented in late 1966. NPPC has launched an extensive effort to make the nation’s pork producers, whether or not they are members of NPPC, aware of the new checkoff plan and its contents. All U.S. pork producers will participate in the 100 percent checkoff, along with all importers of foreign hogs and pork products. NPPC is urging all pork producers to take part in a survey to determine how they would like to see the new checkoff funds in vested. Results of the survey will be an important consideration for LIVESTOCK LATEST « Lvu Bureau ot Animal Industry, told the poultry industry, “It is im perative that proper sanitary procedures be adopted to prevent the introduction and spread of contagious diseases in your in dustry. It is equally important to assure our neighbors that every possible precaution is being taken to protect them. “We urge you to adopt strict sanitary procedures for your program. This must include comprehensive measures to assure that all poultry crates, equipment and vehicles are properly cleaned and disinfected after each use. Shipments of live to halt sales cease poultry auctions is strictly a precautionary measure designed to keep the highly contagious AI from spreading into Delaware’s multi-million dollar poultry in dustry. The ban is effective at midnight Jan. 24, and will be reevaluated in 30 days. Delaware’s three poultry auctions affected are Wilson’s Auction in Lincoln, Carroll’s Sales checkoff plan on the eventual investment decisions to be made by pork producer leaders. The producer survey will be included in the February issue of National Hog Farmer magazine, and the February issue of NPPC’s own monthly member publication, Pork Report. The survey form is also available from state pork producer associations or NPPC headquarters at P.O Box 10383, CREAMERY A Southeast Pennsylvania Sheep Producers Meeting is scheduled for Tues. Feb. 11, at the Meyers Family Restaurant, Route 309 in Quakertown. The meeting will feature Clair Engle, Extension animal scientist, and Dr. Sid Bosworth, Extension agronomist, both from the Penn sylvania State University. Registration and coffee will be from 9:30-10 a.m. At 10 a.m. Engle will begin the program with the topic “Matching Nutrition to Ewe ' 1 ' f. v./ i*v I ..u Southeast Sheep Producers Meeting scheduled poultry and eggs in unsanitary crates should be rejected. Wooden and fiber crates and packing materials should be replaced with impervious materials (plastic or metal) as soon as possible. Provision should be made at or near your facility to permit cleaning and disinfection of crates, equipment and vehicles im mediately after unloading. Dead birds, manure, bedding and other waste materials must be disposed of in a safe and environmentally acceptable manner. “Sanitary shipment of livestock is not easy or cheap. Neither is management of an outbreak of contagious disease, Van Buskirk said. Van Buskirk said the Depart ment is also advising poultry producers and shippers to call ahead if moving poultry products to interstate markets. “The Pennsylvania poultry industry faces stringent con straints on interstate and in ternational movement of its products,” Van Buskirk said. “Prior permits will insure proper delivery by meeting all requirements established by other states. in Felton, and Spence’s in Dover. Agricultural officials remind poultry farmers and others that avian influenza is easily spread and urge Delawareans to avoid any contact with infected areas. Avian influenza, although deadly to chickens and turkeys, is ab solutely no risk to human health through direct contact or by consumption of poultry and eggs. Des Moines, IA 50306. Pork Producers are urged to call a special toll-free phone number at NPPC in Des Moines if they have any questions about the 100 percent plan or any NPPC program or project. The toll-free number may be reached by dialing 1-800-255- 2255, code, 7675, between 8 a.m. and 5 p.m. Central time, Monday through Friday.

From 12 noon to 1 p.m. will be a lunch break and the opportunity to meet other producers. At 1 p.m. Mr. Engle will continue with “Feeding for Market Lamb Production” which will include birth through market weight, ideas on additives, and marketing concerns. He will also touch on informatiqn about the Rocco Foods contract sheep production and how it might be of interest to local producers. The final topic will be “Pasture and .Main tenance” by Dr. Bosworth'who will discuss the basics of soil fertility, establishing a pasture and the cutting and grazing management of pastures. The Feedlot Environment We know feedlot cattle are fed under many different conditions from the opeixlots of the southwest U.S. to the tightly enclosed bams of southeastern Pennsylvania. But under what set of conditions will growth and feed efficiency be optimized? The results of a series of trials from 1979 to 1984 in lowa were recently summarized in the 1986 lowa Beef Cattle Research Report. Environmental conditions were either in an open lot, an open lot with a three-sided shelter or in a confinement building with one side open. Cattle weighing about 700 pounds at the start were used in all trials and they were all fed a high energy ration. Cattle were started at 60-day intervals to study the effects of season of the year on cattle performance. Results are shown in tables 1 and 2. This series of feeding trials can cause us to speculate about a lot of commonly accepted beliefs. How much environmental control can we afford? When should we be feeding cattle? With the justifiable concern about water quality and pollution control how should we design our feedlots? Taken over all months of starting on feed, the cattle that could chose their own environment (shelter) gained faster and had more desirable feed conversions thaneither of the other groups. The confinement cattle did not out perform the shelterless cattle in any month for rate of gain. However the lowa open lots may have been better designed and managed than many in Pennsylvania. They did have slightly improved feed conversions for November and March started cattle but these differences were not significant. We should keep in mind that southeastern' Pennsylvania averages about five inches of rainfall per year than lowa. That increases the problems associated with runoff and pollution.

Pre-registration is —♦ Beef Briefs by Dr. Lester Burdette Penn State Extension Beef Specialist population, pollution and water quality problems it is doubtful we can ever justify open lot cattle feedlots in Pennsylvania. The predictable pollution and runoff problems will not be tolerated in the future. The results of these trials in dicate that in many of our con finement and semiconfinement situations we should pay a lot more attention to ventilation and cattle comfort. Too many times the environment we design is for the comfort of the cattle feeder rather than the cattle. They need protection from cold rains and winds and may benefit from shade in the summer. But we should remember that the thermoneutral temperature for cattle is about 50 degrees F., rather than the 70-plus degrees where we are most comfortable. Therefore, we probably over design cattle housing for feedlot cattle. Opening up the ridge, eyes and side walls in the summer will improve cattle performance. The differences observed ac cording to when cattle were started on feed are interesting but may not have practical ap plication. We have to consider -when our feeds and labor are available as well as when suf ficient numbers of feeder cattle can be purchased. The other im portant variable is seasonality of prices. Cattle started on feed in the spring to to market in the fall and compete with grass cattle and the heavy runs of cull cows. These trials were with yearling type cattle. The results could be dif ferent for calves as far as the ef fects of shelter were concerned. This data does indicate that cattle can select the environment where they will optimize per formance. Maybe we can’t give them the chance under all con ditions, but we can make an at tempt to improve ventilation and environmental conditions.
