“…Cattle, especially, have shown a high susceptibility to copper deficiency (7 7, 23). The clinical signs in the cattle are closely similar to those observed in the moose disease (24,25,26,27). Thus, secondary copper deficiency, chromium deficiency and a disturbance of trace element metabolism have been suggested as the cause of the disease (22).…”

“…Morphological findings of the cardiovascular system showed a very high degree of individual variation in the present study, and were not specific for any group. In earlier studies, vascular lesions like haemorrhages and blood vessel rupture have been described in Cu deficient cattle [ 45 ], piglets [ 32 , 6 , 50 ], chicken [ 39 ] and moose [ 41 ].…”

Experimental Copper Deficiency, Chromium Deficiency and Additional Molybdenum Supplementation in Goats – Pathological Findings

2001

Secondary copper (Cu) deficiency, chromium (Cr) deficiency and molybdenosis (Mo) has been suggested to cause the "mysterious" moose disease in the southwest of Sweden. The present experiment was performed on goats to investigate the clinical, chemical, and pathological alterations after 20 months feeding of a semi-synthetic diet deficient in Cu and Cr. Four groups were included in the study: control group (n = 4), Cu-deficient group (group 1, n = 4), Cr-deficient group (group 2, n = 2) and Cu+Cr-deficient group (group 3, n = 3). Group 3 was additionally supplemented with tetrathiomolybdate during the last 2 months of the experiment. Main histopathological findings in groups 1 and 3 were the lesions in the liver, characterised by a severe active fibrosis, bile duct proliferation, haemosiderosis and mild necroses. Additionally, degenerative alterations of the exocrine pancreas were prominent in groups 1 and 3. Lesions in group 3 were more pronounced than in group 1. In group 3, the skin showed an atrophic dermatosis, while in group 2 a crusty dermatitis caused by Candida spp. was observed. This study shows that liver, pancreas and skin are mainly affected by a long term deficiency of copper and the findings are complicated by molybdenum application while chromium deficiency produced no histomorphological effects in our study.

“…Between 1985 and 1995, Alvsborg disease killed more than a thousand moose. The actual number of affected moose remains unknown (Rehbinder et al, 1991;Steen et al, 1993;Merza et al, 1994). The disease affects all age classes of moose.…”

Two hundred delegates from 14 countries attended and presented more than 150 scientific papers, making it one of the biggest Arctic Ungulate Conferences ever. The scientific and social programme as well as the abstracts have been published in Rangifer Report No. 4, 1999. In an important break with normal practice, keynote speakers included scientists of international reputation who do not normally work with Arctic ungulates. They were asked to review recent work in northern species/ecosystems thus providing the conference with novel criticism and new perpectives. Their papers are published in this volume. Delegates' papers will be published in later issues of Rangifer. The Conference also included a Circumpolar PhD-Network in Arctic Environmental Studies (CAES) workshop: "Reindeer 2000", attended by 47 participants presenting 25 student contributions, 5 keynote lectures and 3 introductory speeches. A Rangifer Special Issue with workshop papers is planned for publication later in 2000.
