The causes, incidence and control of arthritis in swine are discussed. Abattoir condemnation of carcasses for arthritis caused major economic losses for producers in New South Wales. Of 1 117 818 pigs slaughtered in 1979-1980, 1979 (0.18%) were condemned for arthritis.

One side of each of 20 lamb carcasses was dissected into muscle, bone and fat. The other side of each lamb was cross-sectioned at 11 sites. Photographs of cross-sections were scanned with an image analyser to measure the amount of muscle, bone and fat at each site. Estimations of the composition of ...

Deaths in cattle fed sudax hay were attributed to nitrate poisoning. Seventy-three animals out of 157 cattle died after being fed the hay, and 11 of the surviving cows aborted in the next 6 days. Toxicological findings supported this diagnosis with samples of the sudax hay containing up to 3.1% nitr...

Intramural vascular patterns of the jejunum and colon were evaluated during ischaemic strangulation obstruction (ISO, 70 min) and subsequent reperfusion (60 min) in 7 adult anaesthetized horses. Microvasculature of experimental and control segments was described by comparison of results from microan...

Effects of intraluminal distention (25 cm of H2O, 120 min) and subsequent decompression (60 min) on intramural vascular patterns of the small intestine was evaluated in 7 anaesthetized horses. Intraluminal distension (25 cm of H2O, 120 min) was created in 2 jejunal segments in each horse. Experiment...

Nine of ten 13-month-old Aberdeen Angus bulls, injected with 0.25 ml of a sclerosing agent (3.6% formaldehyde in 90% ethanol) in the caudae epididymes, developed epididymitis after nine days. Semen samples collected after 40 days contained numerous motile spermatozoa in one sample, and small numbers...

Between July 1985 and April 1986, mycobacterial lymphadenitis was diagnosed in 6 of 2407 slaughter pigs from a herd in which most animals were raised in confinement. All 6 affected pigs had access to earth-floored pens at least 81 days before slaughter. Infection rate was 9.4% in pigs kept on earth ...

Data were collected for 3636 full-term pigs born in a commercial swine herd to determine the effects of birth weight and clinical disease on survival during the first 3 weeks of life. Logistic regression models were constructed for 7-day survival for all live-born pigs, and for 21-day survival for p...

Serological responses to A. pleuropneumoniae serovar 7 infection were monitored by ELISA in a cohort of 66 pigs between weaning and market. Antibody concentrations were high (63/65 seropositive) at 4 weeks of age but declined to low levels from 8 to 12 weeks. Mean antibody concn rose significantly b...

Half the sows and boars on each of 5 commercial farms that had histories of seasonal infertility were given 4 g vitamin C daily. The other half was unsupplemented. Of 423 sows which were allocated to the experiment during the summer-early autumn of 1978-79, 392 were available for mating during the c...

One hundred and thirtyone faecal samples from cattle clinically suspected of having paratuberculosis were processed using the sedimentation culture method (SM) and the centrifugation culture method (CM) before inoculation into Herrold's egg yolk medium containing mycobactin J (M1), control medi...

Objective: To compare the efficacy of osteoprogenitors in fibrin glue to fibrin glue alone in bone healing of surgically induced ostectomies of the fourth metacarpal bones in an equine model. Study Design: Experimental. Animals: Adult horses (n=10). Methods: Segmental ostectomies of the 4th metacarp...

The financial impact of an outbreak of transmissible gastroenteritis in pigs which occurred in February 1986, was evaluated in a California sow herd (320 sows, 15 boars) through estimating the effects on growth, feed, and profit. Two groups of pigs were studied: pigs born before and surviving the ou...

M. felis was the only organism recovered from the thoracic cavity of a horse with pleuritis. Large numbers of mildly degenerative neutrophils were in the pleural fluid. The horse developed a serological response to M. felis and recovered during hospitalization. Experimentally, a pony was inoculated ...

Using computerized decision-tree analysis and simulation modelling to evaluate control and eradication strategies for pseudorabies virus (PRV) three alternative actions were considered for a hypothetical 100-sow, farrow-to-finish operation: (1) depopulation-repopulation, (2) test-and-removal of sero...

Studies were conducted under experimental and field conditions to determine the effect of infection with M. hyopneumoniae on the immune response in serum as measured by ELISA. Following intratracheal challenge or contact exposure, serologically negative pigs derived from mycoplasma-free piggeries de...

The primiparous food-restricted sows were investigated as to whether individual differences and/or daily variations in levels of chain manipulation and excessive drinking are correlated to individual differences and/or daily variations in pre- or postfeeding glucose concentrations. Blood samples wer...

The distribution, clinical signs, diagnosis, treatment, and prevention and control of Babesia gibsoni infections in dogs are reviewed. This disease affects wild and domestic canids in Asia, Africa, Europe, the Middle East and North America. Common clinical signs include anaemia, pyrexia, anorexia, l...

The extent of the serological cross-reactivity was determined in the indirect fluorescent antibody (IFA) test for B. gibsoni, and the optimal cut-off titre for seropositivity. The lowest titre to B. gibsoni detected in a dog with naturally acquired clinical babesiosis was 1280 and 7 of 12 dogs had t...

A DNA vaccine against infectious haematopoietic necrosis virus (IHNV) is effective at protecting rainbow trout, Oncorhynchus mykiss, against disease, but intramuscular injection is required and makes the vaccine impractical for use in the freshwater rainbow trout farming industry. Poly (D,L-lactic-c...

The welfare of animals in transit may be affected by driving events, such as acceleration, braking and cornering. The relationships between driving events and the behavioural responses of the animals were examined. A single-deck, non-articulated vehicle was with a video-recording system, GPS and tri...

The aim of the study was to measure the effect of radiological hip and elbow dysplasia status and breed on overall survival in a cohort of four large dog breeds in Norway. Privately owned dogs of the Newfoundland (NF), Labrador Retriever (LR), Leonberger (LEO), and Irish Wolfhound (IW) breeds were f...
