Immobilization of muskoxen (Ovibos moschatus) with etorphine and xylazine
One hundred and thirty three "wild" muskoxen, 81 of which of known body mass, were successfully immobilized using etorphine (M99), and xylazine (Rompun®), delivered by use of a dart gun. A dose of 0.05 mg/kg M99, supplemented by 0.15 mg/kg Rompun was found to be very effective. This dose is much higher than currently recommended e.g. by Handbook of Wildlife Chemical Immobilization.
متن کاملSerum Biochemistry and Serum Cortisol Levels of Immobilized and Hunted Muskoxen (Ovibos moschatus) from Northern Canada
Muskoxen (Ovibos moschatus) are Arctic-adapted ruminants native to the Arctic regions of Canada, Alaska, and Greenland. Little is known about the serum biochemistry and serum cortisol of this species, or the effects of chemical immobilization on serum biochemical parameters. This study aimed to describe blood chemistry parameters and cortisol levels in hunted, tame, and chemically immobilized m...
متن کاملFiber characteristics of qiviut and guard hair from wild muskoxen (Ovibos moschatus).
In response to increasing commercial interest and the high market value of qiviut (the downy underwool of the muskox), we have employed standards and measurements used in the wool and cashmere industries to describe qiviut fiber characteristics. Fleece samples (qiviut with guard hair) were shaved from the midshoulder of 299 wild muskox hides of known sex and age (1, 2, 3, and 4+ yr) during the ...
متن کاملCould a big gut be too costly for muskoxen (Ovibos moschatus) in their first winter?
Young mammalian herbivores are more vulnerable to harsh winter conditions than adults, especially among large circumpolar species like the muskox (Ovibos moschatus). We compared feeding responses of muskox calves (body mass 95 kg) with those of mature, non-reproductive females (body mass 227 kg) in mid-winter when air temperatures fell to -40 degrees C. Food intakes (1.8-2.2 kg digestible dry m...
متن کاملFirst insight into the faecal microbiota of the high Arctic muskoxen (Ovibos moschatus)
The faecal microbiota of muskoxen (n=3) pasturing on Ryøya (69° 33' N 18° 43' E), Norway, in late September was characterized using high-throughput sequencing of partial 16S rRNA gene regions. A total of 16 209 high-quality sequence reads from bacterial domains and 19 462 from archaea were generated. Preliminary taxonomic classifications of 806 bacterial operational taxonomic units (OTUs) resul...
