Study Notes

Ruminant Gastrointestinal Diseases and Health Management

Low-threshold receptors in the GI system increase rumen motility, while high-threshold receptors decrease motility.
Clinical signs of ruminant GI diseases include abdominal distension, pain, diarrhea, reduced fecal output, weight loss, inappetence, and bottle jaw.
Diagnosis of vesicular lesions involves differentiating between foot-and-mouth disease (FMD), vesicular stomatitis (VS), and malignant catarrhal fever.
Poultry gastrointestinal diseases include enteric diseases like rotavirus, reovirus, astrovirus, and avian nephritis virus.
Marek's disease in poultry causes enlarged nerves, atrophic bursa, and diffuse lymphoid tumors, leading to lifelong carriers shedding.
Avian nervous system diseases include encephalomalacia from vitamin E deficiency, muscular dystrophy, avian encephalomyelitis, and botulism.
Fowl cholera is a systemic disease in poultry caused by Pasteurella multocida, while fowl typhoid, paratyphoid, colibacillosis, and erysipelas are also prevalent.
Parasitic diseases in poultry include mites, helminths, coccidiosis, and histomoniasis, with prevention involving rotation and deworming.
Pododermatitis in poultry can be managed by addressing infectious and non-infectious gastrointestinal signs, which have multifactorial root causes related to nutrition, housing, normal flora, and pathogens.
Management of ruminant gastrointestinal health involves monitoring rumen fermentation, VFA production, saliva as a buffer, primary and secondary contractions, and health metrics like appetite and production.
Displaced abomasum in ruminants is caused by nutritional factors and can lead to subclinical ketosis and hypocalcemia, presenting with clinical signs like large L-shaped rumen and abdominal fill despite poor appetite.
Infectious enteric diseases in cattle cause diarrhea, which is an indicator of gastrointestinal health and can be managed through optimized growth and proper measurement of milk replacer. Neonate diarrhea can be caused by E. coli, Salmonella, and coronavirus, leading to gastric and glandular mucosal lesions.

Equine Hepatic Diseases Overview

Pentoxyfylline 8 mg/kg po q12h reduces hepatic fibrosis in horses
Silymarin from milk thistle seed extract is hepatoprotective for chronic liver disease in horses
Stress, illness, late gestation, and early lactation can manifest as reduced water and feed intake, depression, diarrhea, colic, fever, ventral edema, and cachexia in horses
Hyperlipidemias in horses are classified as mild hypertriglyceridemia (TG 100 - 500 mg/dL) and severe hypertriglyceridemia (TG > 500 mg/dL)
Hormone Sensitive Lipase promotes gluconeogenesis, glycogenolysis, and lipolysis in horses
Ponies, miniature horses, and donkeys are predisposed to severe hypertriglyceridemia due to negative energy balance
Excessive TG and VLDL production in horses with insulin resistance and obesity leads to hyperlipemia
Chronic megalocytic hepatopathy in horses is stimulated by Senecio spp and Pyrrolizidine alkaloid-containing plants, leading to megalocytosis, biliary hyperplasia, and fibrosis
Clover poisoning in horses, caused by Trifolium and Alsike clover ingestion, can result in cholelithiasis and liver disease
Tyzzers disease, bacterial hepatitis, and Theiler's Disease are acute hepatic diseases in horses with distinct clinical presentations and prognoses
Equine parvovirus, flaviviruses, and equine hepacivirus are associated with hepatic diseases in horses
Chronic active hepatitis in horses can be idiopathic or caused by autoimmune, hypersensitivity, bacterial, or viral factors and is characterized by progressive liver failure
