What beef cattle producers need to know about the upcoming federal regulatory changes for medicated feeds. Medicated feeds are valuable tools that can be utilized by beef cattle producers for various health or production reasons. Such reasons include the treatment, control or prevention of certain diseases, or for growth promotion and feed efficiency.
Infected cattle usually appear and act normal without any outward signs of infection. The first indication of an infected herd will be when cows are examined for pregnancy and too many cows are open (not pregnant), or there is a strung out (prolonged) calving season, or a reduced calf crop (low birth rate).
Many animals in the early stages of Johne's disease may not be seen. Therefore, it becomes a herd problem, besides an individual animal problem. Johne's disease can be prevented, controlled and even eliminated from infected herds, based on a thorough understanding of the disease.
A successful herd health program includes, but is not limited to, proper herd immunization (vaccination) to prevent and/or control a variety of infectious diseases. However, selecting the proper vaccines for your herd can be a difficult task considering the large number of vaccines that are available.
Safety and security on the farm should be a concern for beef producers. The outbreak of Foot and Mouth Disease (FMD) and the potential spread of anthrax to the United States make animal care a very important issue.
Leptospirosis is known to be a common disease of cattle generally resulting in reproductive failure such as abortion and infertility. Leptospirosis is contagious and is spread by cattle including bulls.
Anaplasmosis is a disease of cattle, sheep and goats resulting in anemia and sometimes death especially in adult cattle. This disease is seen worldwide and is a common disease in the southern United States.
Controlling parasites can both improve performance and add value to feeder cattle. Losses in performance and value amount to millions of dollars each year from loss of blood and just plain irritation. This article will present a discussion of control of both external and internal parasites.
Bluetongue (BT) and Epizootic Hemorrhagic Disease (EHD) are diseases caused by similar viruses that are rapidly spread by biting gnats, resulting in similar symptoms in cattle, sheep and whitetail deer, among others.
BVD infections appear to be common in US cattle. The virus can spread through the cowherd rapidly. The calf is the most likely animal to be responsible for spreading the virus. The resulting infection is most likely to be associated with reproductive problems of some kind.
Dallisgrass Staggers is a problem that is likely to be seen in cattle and horses this fall due to the warm, wet summer that we have experienced. Due to the increased growth of warm season grasses, more seed heads will be produced every year and should be managed to prevent this issue.
This is of value to cow-calf producers in evaluating the risk of "downer cows" in their herds. Market "at risk" cows before further deterioration occurs and they still have value. At risk cows that cannot be immediately marketed should be separated from the herd and provide management, health and nutrition programs to reduce the risk.
