Drought Can Increase Feeder Cattle Respirato MILLIE BUNTING Market Staff NEW HOLLAND (Lancaster Co.) “Blame it on the weath er.” That’s the simple answer to county agent Chet Hughes’ ques tion regarding the increase in res piratory problems in feedlot cat tle here last fall. “What went wrong?” Hughes asked. Why were there were un usually high mortalities and labor intensive treatments reported on sick animals? Dr. Arlen Mills The focus of this year’s Cattle Feeders’ Summer Workshop, coordinated by the Lancaster County office of Penn State Co operative Extension, was finding the answer. Hughes and his cooperating sponsors assembled a blue-ribbon panel of experts on feeder calf health to address the respiratory problems of area cattle feeders. “Shipping fever” is the term sometimes given to a runny nosed, lethargic calf in the auc tion ring. But it’s not that simple. Nor is the treatment. There are specific organisms at work and specific vaccines and treatments available to prevent or combat them. “Blame it on the weather.” That explanation was offered as part of Dr. Arlen Mills’ com ments on the respiratory prob lems. A cooperative extension veterinarian based in Lebanon County, he said there were more feeder calves with respiratory sickness last fall in area feedlots because of the weather. Mills explained that respirato ry problems can go in cycles with the weather. The mother on drought-stricken pastures does not provide good colostrum to the calf. That calf will not be as healthy and able to endure the stresses of weaning, sorting, ship ping, loading, unloading all those factors it goes through until it arrives in the feedlot. In preparation for the work shop, Mills conducted producer interviews on six Lancaster County farms to evaluate feeder cattle receiving and processing practices. Before coming to Penn sylvania, he had extensive experi ence working with beef producers as a practicing veterinarian in Ohio for 20 years. He noted that the cattle feeders were very coop erative for his study and he found them very knowledgeable about their cattle. Mills presented a detailed com puter-generated demonstration of his findings, aptly using pictures and charts to evaluate what did or could have gone wrong with so many cattle going on feed last fall. In his presentation, Mills con densed his talk down to the con ditions in three feedlots to illus trate the health problems and what was done to treat the sick calves. Where calves were bom and purchased, preconditioning/ health treatments, transportation to feedlot, nutrition and feeding facilities these factors were all included in his discussion. Mills concluded: • Calves that had one dose of a killed vaccine or two doses months apart were as apt to need treatment as those calves with no vaccination history. • Calves which had received modified live vaccination were much less likely to need treat ment. Supplementing Dr. Mills pre sentation on respiratory problems was Dr. W. Dee Whittier, exten sion veterinarian for cattle, Vir ginia-Maryland Regional College of Veterinary Medicine at Virgin ia Tech. He has done extensive Dr. Dee Whittier research on bovine respiratory diseases and is experienced with the Virginia Quality Assurance feeder calf program. He dis cussed the influence of health on feeder cattle prices. Whittier said he has found that the potential health of calves is one of the significant factors that buyers consider when making a decision about how much to pay for calves. They will pay more for vaccinated and preconditioned calves. After a question about myco plasma, Whittier proceeded with a detailed answer with the aid of modem technology. He just hap pened to have a “power point” presentation on mycoplasma on his notebook computer. So he proceeded to “boot up” the note book and provided up-to-date in formation on the respiratory ill ness. Mycoplasma, Whittier ex plained, is an infectious organ ism, classified bacteria, which has come into more scrutiny in the last three or four years in the U.S. He said the illness has been diagnosed as pneumonia and ar thritis and a culture needs to be done for a specific diagnosis. In the wide shipping fever complex, Whittier believes myco plasma is distinct enough to call it by its own name and it could then be treated more aggressive ly. He said he has seen an in creased incidence of mycoplasma in sale barn calves where there is more exposure than there is on the farm. Dr. John Lynch, a veterinarian with the Technical Services Group of Intervet, Inc., spoke on the preventive medicine available to provide immunology for calf health problems and avoid the previously discussed illnesses. Lynch has 20 years of experience as a veterinary consultant with beef cow/calf, stocker, and feedlot operations in the U.S. and Mexi co. About 150 cattle feeders turned out for the workshop at Yoder’s Restaurant in New Hol land in late July.
