Deer farming is on its increase in Denmark. Based on experiences from other countries, lungworm infection is expected to cause severe problems in farmed deer. Therefore, in the present paper, which is the first one to deal with pathogens in Danish deer farms, the faecal larval excretion in red deer is examined.

Allergic, irritative and photosensitive contact dermatitides make up a group of dermatoses which have traditionally been associated with some difficulties in diagnostication. The reason for this is the problems encountered in setting up, keeping in place, and reading the patch test which is the diagnostic tool relevant to veterinary practice. In the present study, a review of the disease complex is given, and a clinical study, dealing with allergic contact dermatitis, performed with materials and methods available to the small animal practitioner, is discussed with regards to symptomatology, diagnostic work, and therapy. With appropriate management, consisting in an attempt to eliminate the offending item(s), and glucocorticoid therapy adjusted to the clinical response, the disease carries a good prognosis.

The clinical features of a case of granulosa cell tumour in the blue fox (Alopex lagopus) are described. The associated hormonal changes are discussed in relation to present knowledge of the regulation of the oestrous and furring cycles in this species.

Addition of sulphuric acid preserved fish in great amounts as fur animal feed has a serious influence on the metabolism of the animals. The present experimental work shows that several clinical-chemical parameters are changed during feeding of acid preserved feed resulting in changes of the fluid-, electrolyte- and acid-base balance as well as in the immunological status. The changes are most probably due to changes also found in the organ functions. The present work together with earlier investigations by the authors has formed the scientific background for the use of acid preserved fish silage in mink during the last 10 years. This has made it possible to out-distance the competitors further, both with respect to fur quality and feeding costs.

Earlier and present experiments have shown detrimental influence of sulphuric acid preserved fish in mink feed on production parameters, early kit growth and kit mortality. Comparison of the production parameters with clinical-chemical parametres and pathological-anatomical findings give a picture of the tolerated amount of sulphuric acid preserved fish silage in the mink feed during different production periods. It seems that the animals tolerate only small amounts of sulphuric acid preserved fish silage (5-8 per cent) in the total feed during the stress periods of reproduction, lactation and early kit growth but higher amounts (20-30 per cent) during late growth period, where the need of feed is high.

A case of canine uveal malignant melanoma with widespread metastases in a Golden Retriever is presented. In addition all cases of canine ocular neoplasms submitted to the Eye Pathology Institute (EPI) between 1960 and 1985 were reviewed. Intraocular malignant melanoma constituted about 25 percent of the submissions.

The effects of albendazole treatment in late autumn and winter on the spring-rise in faecal nematode egg output and reproductive performance in the ewe were investigated. The control measure effectively prevented the egg output in spring and lambs born to treated ewes had increased birthweights in comparison with those born to untreated ewes.

In the present work a review is given on the aetiology, clinical symptoms, prevalence and significance of the disease eperythrozoonosis in swine. Clinical outbreaks are characterized by fever, anemia and icterus. Clinical signs are most likely to be observed in young suckling piglets and in sows at the time of farrowing. In most cases infection with Eperythrozoon suis leads to a carrier state of symptomless, subclinical infection which, however, may be activated under conditions of stress. Eperythrozoonosis in swine has been reported from the USA, England, Federal Republic of Germany, Belgium and a few other countries. Due to the latent nature and the non-specific clinical symptoms of the disease it seems likely that the prevalence of E. suis in swine populations may be considerably greater than the number of clinical cases might lead one to suppose. So far, E. suis has not been diagnosed in Scandinavia, but it should not be excluded that eperythrozoonosis may exist as a neglected disease in Nordic swine herds as well.

A case of guttural pouch mycosis in an 11-year-old horse is described. The fungus isolated was identified as Emericella nidulans. Housing under bad hygienic conditions without ventilation for three years might have been a predisposing factor.

A field trial was designed to compare the efficacy of a pregrazing treatment with a morantel sustained release bolus and two strategic treatments of levamisole in the prevention and control of gastrointestinal parasitism in first year grazing cattle. The infection of calves, pasture contamination and the subsequent effects on performance were recorded.
