Ingestion of the plant Nolletia gariepina was confirmed as the cause of acute mortalities in cattle in the Kuruman area of the Northern Cape Province of South Africa. The aim of this trial was to investigate the toxic effects of this plant with respect to clinical signs, pathophysiology and pathology using the sheep as a model. At dosages of 1.5 g dried, milled plant material/kg body mass there...

BACKGROUND An elevated plasma glucose concentration has been considered to be a potential risk factor in the pathogenesis of left-displaced abomasums (DA). Therefore the present study was performed to investigate if spontaneous disease (parturient paresis, metritis, ketosis etc) in dairy cows results in elevated concentrations of glucose and cortisol in blood as cortisol is the major regulator ...

Tribulus terrestris herb has been used as a drug in traditional medicine and its toxic effects have also been reported. Less attention has been paid to the interpretation of pathological and laboratory findings in the natural form poisoning with this plant in animals. Following a report of mortalities in a sheep farm feeding on a pasture containing Tribulus terrestris herb and involvement of 50...

Failure to grow (ill-thrift) in calves has a negative effect on animal production and health. The present study was carried out from November, 2009 to May, 2013 to investigate the risk factors of ill-thrift in buffalo calves. A total of 344 calves at 78 smallholder farms were selected randomly. A questionnaire was designed to include managemental, nutritional and disease risk factors. Serum sel...

Ž . Ž . Atlantic salmon weight range 289–484 g and rainbow trout weight range 166–387 g , held in seawater, were fed medicated diets containing graded levels of emamectin benzoate for 7 days. y1 y1 Ž Nominal dose rates were 0, 100, 250 and 500 mg kg body weight day equivalent to 0, 2, 5 . and 10 times recommended dose rate for treatment of sea lice . Fish were observed for a further 7 days to d...

The effect of recombinant bovine somatotropin (bST) on the chemiluminescence, diapedesis, and expression of adhesion receptors (CD11a, CD11b, CD18) of isolated polymorphonuclear leukocytes was studied. The plasma concentrations of insulin-like growth factor-I (IGF-I), bST, cortisol, and alpha-lactalbumin were also monitored. In addition, general and local clinical symptoms and the differentiati...

A 6-year-old Peruvian Paso-Mustang cross mare was presented to the William R. Pritchard Veterinary Medical Teaching Hospital, University of California, Davis during the fall (October) with a 2-day history of lethargy and icterus. The mare was from a herd of 26 mares and 3 foals from which 5 mares had died (leaving 21) during the preceding 7 days. These mares had varying degrees of colic, ataxia...

A 4-year-old male castrated English Mastiff weighing 72 kg (158 lb) was evaluated for acute dyspnea after a 1-week history of restlessness, episodes of increased respiratory effort, and inappetance. The dog was otherwise healthy and received seasonal heartworm preventative medication and routine vaccinations. On initial examination, the dog was bright, alert, responsive, and had a body conditio...

Hemorrhagic bowel syndrome (HBS) is newly-described disorder primarily affecting dairy cattle. Its cause is not known. In this study, the possibilities that Aspergillus fumigatus and Clostridium were involved in etiology of HBS were examined. Samples of feed, gastrointestinal (GI) contents, GI wall, lymph nodes and blood from HBS and control animals were collected in four states (IA, ID, OR, WA...
