摘要:

The pathology of carcinoma of the small intestine in six adult cattle is described. The lesions were similar to those of carcinoma of the small intestine of sheep although a slightly less fibrous stroma and a greater tendency to metastasise was observed. Initial iindings suggest the disease resembles small-intestinal carcinoma of sheep and cola-rectal carcinomas of man in having a higher prevalence in New Zealand than most other countries. This highlights the need to investigate common environmental factors which may be responsible for the induction and promotion of these tumours in both grazing ruminants and man.

摘要:

Serum gamma glutamyl transferase (GGT) levels in blood samples taken from normal lambs which had suckled colostrum were found to be up to 140 times normal adult levels. These high serum levels declined rapidly reaching a stable level approximately 60% higher than normal adult values by 24 days of age. Newborn lambs which had not yet consumed colostrum had GGT levels which would be considered normal in adult sheep. The GGT concentration in ewes' colostrum was up to 470 times normal serum levels. There was a significant positive correlation between serum GGT and gamma globulin levels in blood samples taken from lambs within 24 hours of birth.

摘要:

A study was made of various aspects of 53 naturally occurring cases of foot abscess in sheep in New Zealand. Radiographic techniques were used to follow the progress of the lesion and from this it was concluded that foot abscess could be defined as an infection of the distal interphalangeal joint. The term “foot abscess” was considered preferable to the term “infective bulbar necrosis”.

摘要:

Complement fixation tests using threeB. ovisantigen preparations in warm fixation tests (WCFT) and cold fixation (CCFT) tests were done on 541 ram sera. Semen samples from the same rams were examined culturally to identifyB. ovisexcretors. The CCFT, using an antigen prepared by heat extraction ofB.oviscells, had a sensitivity of 97% in 124 rams which were sheddingB.ovis. The specificity was 99% in 144 rams from non-infected flocks. Seventy-seven per cent of 156 rams which reacted to this test were sheddingB. ovisin their semen. Tests with other antigens were inferior in sensitivity and/or specificity. The WCFT gave lower titres than CCFT. Vaccination caused large numbers of false positive reactions in 4 flocks.

摘要:

In the three years from October 1979 to September 1982 over 6.3 million lambs were processed in two meat works and of these 0.5% had lesions of contagious pustuiar dermatitis (CPD). The proportion of iambs affected was highest in the months of December and January when up to 2.2% of the Iambs slaughtered had lesions of CPD. On average 13.4% of a consignment (referred to as a line) of lambs showing evidence of CPD were affected. The total lambs in affected lines constituted 4.1% of the total slaughtered.

摘要:

Data from 763 cases of clinical canine parvovirus disease confirmed at the Ruakura Animal Health Laboratory were examined. The largest number of cases were seen in spring and summer months with the peak incidence in February 1981. The morbidity and mortality rates were highest in young dogs. Sixty-nine percent of all cases occurred in dogs less than six months of age, and 63 percent of dogs seven weeks of age or younger died. The laboratory methods used to diagnose canine parvovirus disease are compared and discussed.
