The pliers are connected to a flexible, plastic coated steel tube terminating in a bronze headpiece. Inside this tube a polyfilament, stainless steel wire connects the pliers to an attachment screw in the headpiece. Before treatment the bolus is screwed on to this screw. After the bolus has been guided through the pharynx and oesophagus into the rumen, it is released by squeezing the pair of pliers which then retracts the attachment screw and allows the bolus to drop off. Spring loading of the attachment screw ensures retraction of the screw into the headpiece if the bolus is lost during the operation. The equipment has been used for treatment of more than 1000 reindeer.</p><p>Utstyr for nedf&oslash;ring av tabletter i vomma p&aring; rein.</p><p>Abstract in Norwegian / Sammendrag: Et nedleggingsutstyr for innf&oslash;ring av vomtabletter i vomma p&aring; rein blir beskrevet. Vomtablettene har en diameter p&aring; 18-20 mm og en lengde p&aring; 50-60 mm. Utstyret best&aring;r av en tang som via en b&oslash;yelig, plastbelagt spiralwire er forbundet med et hodestykke i bronse. En polyfilament st&aring;lwire g&aring;r inne i spiralwiren fra tangen til hodestykket hvor den ender i en festeskrue. For behandling skrues festeskruen inn i et hull i bakflaten av vomtabletten. Etter nedf&oslash;ring i vomma frigj&oslash;res tabletten ved at festeskruen med kraft fra tanga trekkes ut av tabletten. Fj&aelig;rbelastning av festeskruen sikrer at skruen trekkes inn og beskyttes i hodestykket dersom tabletten mistes under behandling av urolige dyr. Det er behandlet ca 1000 rein med nedleggingsutstyret. En behandling med to tabletter tar 2-5 min. pr. dyr inkludert nedlegging og fiksering av dyret.</p><p>&nbsp;</p> ER -
