A36-Lancasler Fanning, Saturday, April 15,1989 York Holstein Breeders (Continued from Page At) new technology, confronted with the same industry suspicion which greeted A.l. and bulk tanks. But, controversial or not, BST, if and when approved by FDA, could be available for dairy farmer use within the year. The university is taking no position on the product, but making available to farmers compiled research findings. BST is a natural protein hor mone needed by all mammals, produced in the bodies of both cows and humans, and is naturally found in milk. It helps to coordi nate how energy from feed intake is utilized in the animal’s system. After extensive testing, no increase has been found in the levels of BST in milk from treated animals over the BST levels in milk from non-treated, control animals. Since it is a protein, BST is not orally active if ingested by mouth, nor is it harmful if acci dentally injected. Frequency of dosages range from daily to monthly, depending on how each firm producing the product establishes usage. How ever, says Dr. Muller, dosage intervals of two to four weeks seem most palatable. Adaptation of cows to the periodic injections has not been a problem. Production response per head, from compiled statistics of seven separate research stations, ranged in the area of 8 to 11 pounds milk increase per day, and within three to four days of BST administra tion. A 15 percent increase, or 8.4 Ag Teachers In Workshop BLUE BALL The Lancaster County Vocational Agriculture Teachers Association sponsored a welding workshop in cooperation with M.H. Eby of Blue Ball on Wed., April 12. The workshop involved a tour of the aluminum trailer manufac turing plant and hands-on instruc tion by welders employed by Eby using MIG welders. Company representatives from Century Manufacturing and Keystone Gas made presentations about equip ment available from their companies. The workshop was planned by the ag teacher group to better pre pare them in the new fields of agriculture mechanics. Because the teachers are training students for a vocation in a field of agricul ture it is important for them to be up to date with the new technolo gies in today’s agriculture indus tries. Several schools are consid ering adding MIG type welders to their agriculture curriculum. Bill Shrum, human resource manager for M.H. Eby, stressed the constant need for workers with sound mechanical abilities. He encouraged the ag teachers to expose their students to a variety of mechanical skills such as MIG welding. Several agriculture stu dents from local high schools have worked with employees at Eby on an On-The-Job Training Co-Op Program. A number of workshops have been planned by the LCVATA in an effort to stay on the “Leading Edge” of the new fields of agricul ture. Students interested in a career in agriculture should con tact their local agriculture prog ram instructors. pounds milk per head per day, was an overall average production response to BST. BST efficiency was greatest when administered beginning at 80-90 days into lactation, just after production peaked. With an esti mated 215 days remaining in a 305-day lactation, at an additional 8.4 pounds per day, an average gain of 1800 pounds per lactation might be expected with BST. Most successful response was in mature cows, those in second or greater lactations, ranging from 6 to 13 pounds per day increases. First lactation cows show less overall average response, from 1 to 6 pounds per day increase, pos sibly due to continuing body growth to maturity. Feed intake, however, must be increased 5 to 10 percent, to com pensate for the greater energy needed by the cow to produce additional pounds. Without increased feed levels, animals draw extra production resources from their own body reserves. And, a delay in administering BST until about 90 days helps avoid putting the cow in a negative ener gy intake position during the first months of heavy production after freshening.

Body reserves, noted Dr, Mull er, must be restored during late lactation arid the dry period. With BST usage, dairy producers might have to redo feeding programs to provide higher energy intake to end-lactation, dry, and “close” cows. “BST management strategies are similar to those used for all high production cows,” he advised. Economics of BST will have to be weighed in each individual dairymen’s management situa tion. It requires no capital invest ment outlay, but does impact costs through increased labor, feed, and cost of the product itself. Other profitability factors include herd health, milk price, rate of industry acceptance and long-term response. While researchers have no sure fire way of guaging dairy industry acceptance, projections are for IS to 25 percent early acceptance of BST increasing to up to SO percent within five years after and, if, approved for use. A 25-percent adoption rate of Chore-Time*s ULTRAFLO® feeder can free you from your chains We have probably been too modest up to now about the merits of our new generation ULTRAFLO® cage feeder vs. the old style chain feeders some of our competitors are still trying to sell you. In fact, the only negative comments about ourfeeder come from our competition, not our customers. So we would like to point out the bare facts: Get The BST, at the average lactation increase of 1800 pounds, would increase production nationwide by an estimated 3 percent. Likewise, a 50-percent adoption rate, about the industry usage rate of DHIA testing, would boost production about six percent. FDA approval is expected when safety for use on cows, as well as safety for meat and milk con sumption by the public has been satisfactorily demonstrated, and the product is deemed an effective industry production tool.
