Veterinarians in the production setting: where do veterinarians fit in? What can they provide? What skills do they need?

This article examines the changing direction of needed competencies for the veterinary medical professional in food-supply veterinary medicine.     

Where do we go in protection against pathogens?

A few reflections are made on the future strategies and approaches for combating infectious diseases of livestock, keeping into consideration public concern on food quality and availability. The policy of eradication of pathogens/diseases instead of vaccination has rendered livestock naive to certain pathogens and as a consequence susceptible to epidemic outbreaks, even more so as we have to conclude that outside attack is quite often difficult to control. Therefore, immunoprophylactic measures in livestock remain top priority and will in the future focus more on the induction of mucosal immunity and the activation of innate immunity.     

Pain control in horses: What do we really know?

Currently, approaches to pain control in horses are a mixture of art and science. Recognition of overt pain behaviours, such as rolling, kicking at the abdomen, flank watching, lameness or blepharospasm, may be obvious; subtle signs of pain can include changes in facial expression or head position, location in the stall and response to palpation or human interaction. Nonsteroidal anti‐inflammatory drugs (i.e. phenylbutazone, flunixin meglumine and firocoxib), opioids (i.e. butorphanol, morphine and buprenorphine) and α₂‐adrenergic agonists (i.e. xylazine, detomidine, romifidine and medetomidine) are the most commonly used therapeutic options. Multimodal therapy using constant‐rate infusions of lidocaine, ketamine and/or butorphanol has gained popularity for severe pain in hospitalised cases. Drugs targeting neuropathic pain, such as gabapentin, are increasingly used for conditions such as laminitis. Optimal strategies for management of pain are based upon severity and chronicity, including special considerations for use of intra‐articular or epidural delivery and therapy in foals. Strategies that aim to mitigate adverse effects associated with use of various analgesic agents are briefly discussed.     

Inflammatory bowel diseases in horses: What do we know?

Chronic inflammatory bowel diseases (IBDs) are a group of gastrointestinal (GI) disorders described in both humans and animals, but unlike in other species, in horses they are poorly defined and there is a lack of standardisation of the method of diagnosis. Although there is an impellent need of consensus on the nomenclature, diagnostic work-up, diet, treatment and management of horses with a suspected IBD, the aim of this review is to give initial guidelines for practitioners dealing with suspected cases. It provides a summary of the most relevant literature on the topic and presents the current knowledge on the clinical signs, diagnostic work-up, treatment and prognosis of IBDs in horses.     

What's in a Name? Classification of Diabetes Mellitus in Veterinary Medicine and Why It Matters

Diabetes Mellitus (DM) is a syndrome caused by various etiologies. The clinical manifestations of DM are not indicative of the cause of the disease, but might be indicative of the stage and severity of the disease process. Accurately diagnosing and classifying diabetic dogs and cats by the underlying disease process is essential for current and future studies on early detection, prevention, and treatment of underlying disease. Here, we review the current etiology‐based classification of DM and definitions of DM types in human medicine and discuss key points on the pathogenesis of each DM type and prediabetes. We then review current evidence for application of this etiology‐based classification scheme in dogs and cats. In dogs, we emphasize the lack of consistent evidence for autoimmune DM (Type 1) and the possible importance of other DM types such as DM associated with exocrine pancreatic disease. While most dogs are first examined because of DM in an insulin‐dependent state, early and accurate diagnosis of the underlying disease process could change the long‐term outcome and allow some degree of insulin independence. In cats, we review the appropriateness of using the umbrella term of Type 2 DM and differentiating it from DM secondary to other endocrine disease like hypersomatotropism. This differentiation could have crucial implications on treatment and prognosis. We also discuss the challenges in defining and diagnosing prediabetes in cats.     

Research note: is starch utilization for fat deposition in man different from that in animals?

Utilization of starch for fat deposition in humans was investigated by means of the nitrogen-carbon-balance method in a respiration chamber using the difference principle with a basal and a supplemental period. The basal diet was designed to maintain an adequate energy balance of the volunteer and to meet the maintenance requirements of protein, minerals and vitamins. The dietary fat content was minimized to 2.7% of DM. The digestibility of starch energy was determined to be 97%. The estimated efficiency of ME utilization of starch for energy deposition in humans amounted to 75.8%, which was in accordance with former results in pigs and rats. This suggests that in case of an intake of diets rich in carbohydrates and low in fat the utilization of carbohydrates for lipogenesis in humans is similar to that in monogastric mammal animals.
