Congenital, infectious, neoplastic, nutritional and toxic causes of cardiac disease are occasionally encountered in primary and referral bovine practice. The presentation accompanying these proceedings will review the most commonly encountered conditions with an emphasis on dairy cattle in the Northern United States.
There has been a lot of discussion in the past 10-15 years regarding the number of Food Supply Veterinarians (FSV) and/or Rural Veterinary Practitioners (RVP). The difference in these two populations is that FSV include government veterinarians (APHIS and FSIS), researchers, educators and other veterinarians that are somehow connected with a food animal production.
Trichomoniasis is a sexually transmitted reproductive disease of cattle caused by Tritrichomonas foetus (formally named Trichomonas foetus). There has been a re-emergence of the disease due to increased movement of breeding cattle across the country. The disease is characterized by infertility and early embryonic death.
A large focal right sided ping (>3" diameter) is due to an abnormality of the abomasum or large intestine. Rarely, post-parturient cattle with metritis may have a vague right sided ping in the right caudo-dorsal abdomen due to gas in the uterus.
Health management can be a critical component in adding value to calves. Whether calves are sold at weaning, after pre-conditioning or backgrounding or retaining ownership through the feeding phase a health management program is important.
An absolute requirement for treating ketosis in cattle is to identify and treat the primary cause for the negative energy balance. Symptomatic treatment for ketosis without attacking the primary cause is doomed to failure.
There are many ways to feed a transition dairy cow, specifically a prefresh cow. They include low-energy, high-forage diets that are identical to the diet fed far-off dry cows, the far-off dry cow ration with additional additives such as anionic salts or rumen-protected choline, or a separate prefresh ration with an energy level intermediate between the far-off dry cow ration and the fresh cow diet.
Beef production is shifting toward a consumer focus and new areas are achieving more attention including: individual animal identification, value-based marketing, food safety, as well as source, process, and age verification.
