Weight development and survival rate of reindeer calves treated against Oedemagena tarandi L and Cephenemyia trompe L
Three trials with treatment of reindeer warbles are carried out. All treated groups were injected intramuscularly with Warbex (35%, American Cyanamid), dosage 10 mg active ingredient/10 kg live weight. In total 911 calves and 403 adult females were included in the experiments. All animals were indiv...

| Summary: | Three trials with treatment of reindeer warbles are carried out. All treated groups were injected intramuscularly with Warbex (35%, American Cyanamid), dosage 10 mg active ingredient/10 kg live weight. In total 911 calves and 403 adult females were included in the experiments. All animals were individually marked with plastic eartags. The trials tried to give answers as to the effect of treatment on: a) weight development during winter, b) weight development to the normal age of slaughter (18 months) and c) loss rate during winter. One trial deals with the effect of weight loss during winter by different date of treatment. All studies are undertaken within sex. Generelly the trials show that treated animals lost more weight during winter than untreated. There was found significant higher weight loss for treated female calves (0.7 kg, p=0.005) in the period January 13. — April 28. in trial I and for male calves (0.8 kg, p=0.01) in the period February 14. — April 4. in trial II. There is a trend that treatment increases the slaughter weight. A significant higher increase in the slaughter weight (0.8 kg, p=0.05) of treated male calves was found in trial III. No effect was found by treatment in the loss of animals in winter. The calves lossed during winter had a significant lower live weight at the start of the trial compared to those which survived. In the period February 14. — April 4. there was a higher weight loss in the male calves which were treated on February 14. compared to those treated on November 27. (0.5 kg, p=0.01). Forsøk med behandling av reinkalver mot reinbremslarver (Oedemagena tarandi L og Cephenemyia trompe L). Effekt på kalvens kondisjon målt ved levende vekt og overlevingsevne. Abstract in Norwegian / Sammendrag: Det er utført tre forsøk med behandling av rein mot reinbremselarver (Oedemagena tarandi L.) og Cephenemyia trompe L.). I alle forsøk er brukt intramuskulær injeksjon av Warbex (Am. Cyanamid) 35% med dosering 30 mg aktivt stoff pr. 10 kg levende vekt. I alt inngår 911 kalver og 403 ... |
