Fort Collins, Colo. — The United States Department of Agriculture's National Animal Health Monitoring System collected data from selected beef feedlots throughout August in an effort to identify animal-health management practices and antimicrobial use patterns.
Respiratory disease continues to present challenges in the dairy industry in the 21st century. Traditionally, veterinary curricula have emphasized an etiologic approach to the subject and veterinary practitioners are very familiar with the well documented and heavily researched infectious causes such as bovine respiratory syncytial virus (BRSV), infectious bovine rhinotracheitis (IBR), bovine viral diarrhea virus (BVDV), Mannheimia haemolytica, Pasteurella multocida and Mycoplasma spp.
With the expansion of the size of individual dairy farms feeding waste milk from treated cows to bottle calves has become more common. Waste milk has the potential to have approximately 30% fat and 25-27% protein on a dry matter basis and therefore has the potential to provide a higher plane of nutrition than traditional 20% protein, 20% fat milk replacers.
Respiratory disease continues to be the major cause of disease in feedlot. On average about 15% of feedlot cattle will have respiratory disease compared with less than 2% for digestive or any other disease problem.
Optimizing reproductive success in cow-calf herds relies on combining appropriate immunization and biosecurity practices with the current production system management techniques in the herd. The goal of the immunization program is to match herd immunity to the risks faced.
On January 30, 2008 the beef industry was reminded of the importance animal care. The Humane Society of the United States (HSUS) released a video showing abuse of compromised dairy cattle at a California slaughter house.
