For 3 weeks, 128 male Sprague-Dawley rats, 3 weeks old, were fed on diets containing no protein, casein, soyabean meal, roasted or raw soyabeans, or sweet white lupin (Lupinus albus) cultivar Primorski or Ultra without or with 0.1% lysine or 0.2% methionine. Relative net protein ratio (RNPR) (casein...

Programmed cell death and apoptosis have now been recognised as biological phenomena which are of fundamental importance to the integrity of organisms. What may have evolved as an altruistic defence against pathogen invasion in simple organisms is now a major regulatory mechanism in the development ...

Termination of pregnancy (abortion) was successful in four of four bitches that received PGF(2)alpha (125 mug/kg bid s.c.) and in two or four bitches that received bromocryptine (62.5 mug/kg bid po) for up to 6 d beginning 43 to 45 d post ovulation. Four sham-treated controls whelped normally at ter...

A study comparing invasive versus oscillometric techniques for the measurement of arterial blood pressure was carried out in 4 anaesthetised sows undergoing laparoscopy. Regression analysis was used to determine the correlation coefficient. Bias was 19.2 for systolic, 20.6 for mean and 18.8 for dias...

This study evaluated the sensitivity, specificity and positive predictive value/negative predictive value of the CITE ELISA, the first version of the SNAP ELISA, and the revised version of the SNAP ELISA (SNAP ELISA 1 and SNAP ELISA 2, respectively). This study also evaluated a non-commercial versio...

A fistula of the parotid salivary duct is an abnormal communication between the duct and the skin, resulting in the drainage of saliva to the exterior. Fistulas of the parotid gland or duct are usually due to trauma but may be idiopathic (Pascoe 1999); they are known to occur in human beings, dogs a...

A computerized health and production information network (APHIN: Animal Productivity and Health Information Network) was developed in Prince Edward Island (P.E.I.) to serve the livestock industries. The dairy portion of the network is designed primarily to aid in the reduction of the unit cost of pr...

A 4-year-old ewe with weight loss, anorexia, and high liver enzyme activities was diagnosed at necropsy as having cholangiocellular carcinoma that had metastasized to kidneys, adrenal glands, heart, lungs, mediastinum, and peritoneal surface of the diaphragm. Cholangiocellular carcinoma is an uncomm...

Current models or frameworks used to represent and/or conduct research on determinants of human health have lagged behind in adopting emerging concepts of ecosystems: multiple spatial and temporal scales; nested hierarchies of socioeconomic and biophysical environments; inherent complexity of interr...

A previously reported increase in Nocardia mastitis in Canada was associated with the use of neomycin-based dry cow mastitis preparations; their production and distribution ceased in 1989. Since then the frequency of Nocardia isolations has declined in most provinces, particularly in British Columbi...

This paper summarizes the results of a project carried out between 1979 and 1982. The work is reported fully in six papers which are being published in Preventive Veterinary Medicine. [For Part 1 see VB 54, 1771]..

Control of leaf and head rot of Chinese cabbage (Brassica campestris subsp. pekinensis [Brassica pekinensis]), caused by Pythium tracheiphilum, was obtained by Clonostachys rosea (isolate IK726) in field trials conducted in 1995 and 1999 on a naturally infested land in Denmark. A significant 2- to 3...
