The archaeological site of Quebrada Tacahuay, Peru, dates to 12,700 to 12,500 calibrated years before the present (10,770 to 10,530 carbon-14 years before the present). It contains some of the oldest evidence of maritime-based economic activity in the New World. Recovered materials include a hearth, lithic cutting tools and flakes, and abundant processed marine fauna, primarily seabirds and fish. Sediments below and above the occupation layer were probably generated by El Nino events, indicating that El Nino was active during the Pleistocene as well as during the early and middle Holocene.  相似文献   

Effect of maternal ketoacidosis on the ovine fetus

Ketoacidosis during pregnancy carries significant risk of intrauterine fetal demise, but little is known about the impact of ketoacids on the ovine fetus. We report a case series of maternal ketoacidosis in ewes. Maternal ketoacidosis may result in biochemical and acid-base fetal abnormalities associated with changes in feto-placental unit perfusion.  相似文献   

Respiratory disease in neonatal cloned calves     

Brisville AC  Fecteau G  Boysen S  Dorval P  Buczinski S  Blondin P  Smith LC 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2011,25(2):373-379

Background: Numerous clinical abnormalities occur in cloned calves during the neonatal period. Objectives: Describe respiratory diseases affecting cloned calves. Animals: Twenty‐five cloned Holstein calves. Methods: Retrospective clinical study of the cloned calves born at the Veterinary Teaching Hospital, Saint‐Hyacinthe, QC. Results: Records of 31 cloned calves were reviewed. Twenty‐five records were included. Four stillborn calves and 2 calves euthanized at birth were excluded. Twenty‐two calves suffered from respiratory diseases. Nineteen calves received intranasal oxygen treatment (INO). They were tachypneic (78 breaths per minute) and 5 of them were hypoxemic (PaO₂ < 55 mmHg). Two of 19 calves remained hypoxemic despite INO. Thirteen calves were weaned from INO after a median of 70 hours and were discharged at a median of 5 days of age. Nine calves required ventilatory support: 3 from birth and 6 after INO. Five were successfully weaned from the ventilator after a median of 32 hours and were discharged at a median of 8 days of age. Three calves died and 1 was euthanized because of respiratory disease. Necropsy revealed atelectasis, pulmonary congestion, and alveolar damages. Conclusion and Clinical Importance: Respiratory disease occurs frequently in cloned calves. The most frequent abnormality is hypoxemia because of V/Q mismatch. It is possible to successfully support these calves by INO and mechanical ventilation.  相似文献   

Presumptive bovine neonatal pancytopenia in a Holstein calf in Québec     

Gosselin VB  Fecteau G  Nichols S 《The Canadian veterinary journal. La revue veterinaire canadienne》2011,52(7):788-790

An 18-day-old heifer was presented with fever, depression, tachycardia, tachypnea, and prolonged bleeding time. Blood tests revealed severe anemia, thrombocytopenia, and leucopenia. The animal was negative by PCR for bovine virus diarrhea virus antigen. The findings supported a diagnosis of bovine neonatal pancytopenia. Treatments included fresh whole blood transfusion and antibiotics. The animal recovered fully.  相似文献

Persistence of Mycobacterium avium subsp. paratuberculosis in soil,crops, and ensiled feed following manure spreading on infected dairy farms     

Marie-Eve Fecteau  Ernest Hovingh  Robert H. Whitlock  Raymond W. Sweeney 《The Canadian veterinary journal. La revue veterinaire canadienne》2013,54(11):1083-1085

The goal of this study was to determine the persistence of Mycobacterium avium subsp. paratuberculosis (MAP) in soil, crops, and ensiled feeds following manure spreading. This bacterium was often found in soil samples, but less frequently in harvested feeds and silage. Spreading of manure on fields used for crop harvest is preferred to spreading on grazing pastures.  相似文献   

The nutritional management of gastrointestinal tract disorders in companion animals     

WG Guilford  ME Matz 《New Zealand veterinary journal》2013,61(6):284-291

Dietary protein, carbohydrates, fats and fibre have marked influences on gastrointestinal tract function and dysfunction. This article reviews the nutritional management of common gastrointestinal disorders in companion animals and introduces some of the current areas of research including probiotics, prebiotics, protein-hydrolysate diets, immunonutrition and dietary fibre.

Nutritional management of oesophageal disease revolves around varying the consistency of the diet and feeding the animal from an elevated container. Provision of bowel rest remains the mainstay of the management of acute gastroenteritis but food-based oral rehydration solutions are a useful adjunct. The recommended diet for chronic small bowel diarrhoea is a highly digestible, hypoallergenic, gluten-free, low-lactose and low-fat diet with modest amounts of fermentable fibre. The use of probiotics in the management of diarrhoea in companion animals has not yet been shown to be beneficial. It is likely that prebiotics will prove more effective than probiotics in the prevention of enteropathogenic infections.

Approximately 50% of cats in New Zealand that suffer from chronic idiopathic vomiting or diarrhoea will respond to a novel-protein-elimination diet and approximately 30% meet the diagnostic criteria for food sensitivity. Growing evidence supports the use of protein-hydrolysate diets in the management of inflammatory bowel disease and further advances in immunonutrition are expected. The dietary management of colitis should include a hypoallergenic diet with a fermentable fibre source.

Manipulation of the diet provides clinicians a powerful therapeutic strategy to be used alone or concurrently with drug therapy in the management of gastrointestinal disorders.  相似文献

Effect of a single dose of dexamethasone on glucose homeostasis in healthy horses by using the combined intravenous glucose and insulin test     

Haffner JC  Eiler H  Hoffman RM  Fecteau KA  Oliver JW 《Journal of animal science》2009,87(1):131-135

Sustained dexamethasone administration to horses results in insulin resistance, which may predispose them to laminitis. A single dose of dexamethasone is commonly used as a diagnostic aid, yet the effect of a single dose of dexamethasone on glucose homeostasis in horses is not well defined. The objective of this study was to characterize the change in glucose dynamics over time in response to a single dose of dexamethasone. A combined glucose-insulin tolerance test (CGIT) was performed on 6 adult geldings before and at 2, 24, and 72 h postdexamethasone (40 microg/kg of BW, i.v.); a minimum of 1 wk of rest was allowed between treatments. Before any treatment, the CGIT resulted in a hyperglycemic phase followed by a hypoglycemic phase. Dexamethasone affected glucose dynamics in 3 ways: 1) at 2 h, dexamethasone shortened the ascending branch of the negative phase (P < 0.001) of the test, indicating moderate insulin resistance; 2) at 24 h, dexamethasone impaired glucose clearance by extending the positive phase and eliminating the negative phase while insulin was elevated before the CGIT, indicating a decreased response to insulin; and 3) at 72 h, dexamethasone caused a deeper nadir value (P < 0.001) compared with predexamethasone, indicating an increased response to insulin. It was concluded that dexamethasone decreased the response to insulin as early as 2 h and maximally at 24 h. At 72 h, dexamethasone caused an increased response to insulin, which was unexpected.  相似文献
