Common neurological diseases in food animal (Proceedings)
November 1st 2010Maybe this doesn't really fit "common" but it is always interesting to hear about cases. The main thing about rabies in cattle (and other species) is that signs are quite variable and inconsistent. Certain signs should be "red flags" for bovine rabies. Oftentimes cattle with rabies will have some history of hindlimb ataxia, weakness, or paralysis (this in itself is typical of many bovine diseases but for cattle exhibiting these signs, rabies should be considered).
Role of bovine viral diarrhea virus in feedlots (Proceedings)
November 1st 2010Bovine viral diarrhea virus (BVDV) is one of the most important infectious agents of cattle. The annual economic loss caused by BVDV is difficult to quantify but certainly is significant. The insidious nature of BVDV combined with the biology of the virus and complex disease pathogenesis has made control and prevention of this virus challenging.
Small ruminant parasite control (Proceedings)
November 1st 2010The most common reason for anemia in the small ruminant is internal parasitism. Hemonchus contortus (the barber pole worm) is a voracious bloodsucker that typically resides in the abomasum. The condition may occur in both young stock and adults alike. With the ever increasing issue of parasite resistance, practitioners will be faced with the severely anemic small ruminant. Providing that there are no other serious disease conditions, these cases can have successful outcomes.
Clinical mastitis treatment efficacy: Are we making progress? (Proceedings)
November 1st 2010Mastitis is considered one of the most costly diseases of dairy cattle and one of the most common reasons for antibiotic treatment on dairy farms. There are numerous treatments (both antibiotic and non-antibiotic) for clinical mastitis.
Mastitis control: do the old ways still work? (Proceedings)
November 1st 2010The development and effectiveness of the standard milking time hygiene practices and dry cow therapy were established in the 1960's. Because of the effectiveness of these practices, mastitis has evolved on many farms to primarily environmental rather than contagious pathogens. The purpose of this article is to perform a literature review (especially trying to find studies published after the year 2000) as to the effectiveness of the various mastitis control practices in today's progressive dairy farm.
Integrated BVD control plans for dairy operations (Proceedings)
November 1st 2010More than 60 years ago an enteric disease of cattle was described in North America that was characterized by outbreaks of diarrhea and erosive lesions of the digestive tract. The disease was called bovine viral diarrhea virus or BVD. The virus causing BVD was named bovine viral diarrhea virus (BVDV).
Hypertriglyceridemia and other disorders of lipid metabolism (Proceedings)
November 1st 2010The fed camelid supplies most of its body energy needs through the short chain fatty acid products of gastric fermentation. These are made in roughly the same proportion as in ruminants on similar diets, with the difference that the camelid gastric wall does not appear to convert butyrate to its ketone form. Short chain fatty acids may be oxidized by most tissues.
Integrated BVD control plans for beef operations (Proceedings)
November 1st 2010More than 60 years ago an enteric disease of cattle was described in North America that was characterized by outbreaks of diarrhea and erosive lesions of the digestive tract.17 The disease was called bovine viral diarrhea virus or BVD. The virus causing BVD was named bovine viral diarrhea virus (BVDV).
Environmental role in the epidemiology, transmission and diagnosis of Johne's disease (Proceedings)
November 1st 2010Mycobacterium avium subspecies paratuberculosis (MAP), the causative agent of Johne's Disease (JD), is prevalent worldwide. The NAHMS Dairy 1996 study, estimated 21.6% of the dairy herds in the US were infected with MAP, resulting in annual economic losses for the dairy industry of $200-250 million.
Contrast radiography (Proceedings)
November 1st 2010The advantage of contrast studies is that they highlight and allow assessment of the tissue-contrast interface, and allow assessment of the size, shape, location and patency of various viscera. Contrast can be used to locate structures not apparent on survey films, such as masses, obstructions, and foreign object.
Practical fluid therapy (Proceedings)
November 1st 2010The goals of fluid therapy in camelids are similar to those in other species. The mechanics and details are somewhat different. Of the possible routes, oral and intravenous are the major routes used to correct problems of hydration. Subcutaneous, intraperitoneal, and intraosseus administration all have specialty applications, but are not useful or necessary in most situations.
Farm animal problem solving (Proceedings)
November 1st 2010The majority of food animal veterinarians do their best to make the most appropriate decisions for their clients' livestock. But there are times when we simply don't know what the best decision is. Likewise, there are times when a "new" procedure or "new" product is suggested by the client or one of our colleagues that we are unaware of or have not tried. Problem solving requires the use of multiple sources to educate oneself about the particular problem.
Sick cria management: the Tennessee method (Proceedings)
November 1st 2010Dealing with a sick cria and an anxious client can be quite daunting at times. This task becomes less daunting when one understands the main problems and how to manage them. Neonatal crias are typically admitted to the UT College of veterinary medicine due to prematurity/weakness/inability to stand, suspected or real failure of passive transfer (FPT), and septicemia.
Idea Exchange: Switch needles to ease vaccine administration
November 1st 2010When I administer a vaccine to my patients, especially cats and small dogs, I use the original needle on the syringe only to withdraw the liquid from the diluent vial, inject it into the vaccine vial, and withdraw the vaccine.
How drugs move through the body (Proceedings)
November 1st 2010In most cases, we administer drugs at a different site than we want to drug to act. Understanding how drugs get to their site of action and how long they stay there is essential to making therapeutic decisions about which drug, what route, how much, how often, and for how long.
Managing gallbladder mucoceles (Proceedings)
November 1st 2010A gallbladder mucocele is an enlarged gallbladder that contains an excessive amount of mucus. Histologically, the gallbladder mucosa is characterized by cystic mucosal hyperplasia, with or without inflammation or necrosis. Dogs with gallbladder mucoceles can be asymptomatic early in the course of disease.
Fever of unknown origin: interesting feline cases (Proceedings)
November 1st 2010Cats with fevers (103? F-106? F) are a common occurrence in everyday practice. Most cases respond to antibiotic therapy or are self-limiting (abscesses, viral infections, post-surgical fevers). However, the most frustrating case is one in which a routine course of antibiotics does not improve the clinical condition of the cat, routine diagnostics do not identify the cause and the fever is ongoing.
Toxicology Cases That I've Known and Loved – Part 1 (Proceedings)
November 1st 2010A 2-year-old male cat was being treated for urinary obstruction at a veterinary hospital. Immediately after his intravenous catheter was flushed with a pre-filled syringe of what was believed to be heparinized saline, the cat urinated, tremored, torsed and collapsed. Hospital staff could not resuscitate the cat.
Using titers to diagnose disease: when is a positive a positive? (Proceedings)
November 1st 2010For most diagnostic tests, the 'titer' is the minimum dilution of a substance that is required to yield a positive result. For example, for detection of anti-Leptospira sp. Antibodies, the titer is the dilution of serum which still causes microbes to crosslink.
