An evaluation of the quality and physical properties of calf leather following topical application of eprinomectin.

The gross and histological appearance of skins obtained from twelve 6-10 month-old Friesian X Hereford calves 14-15 days after they were treated with a topical formulation of 0.5% eprinomectin administered at 1 ml per 10 kg bodyweight was compared to that of skins from twelve untreated controls. No significant differences were observed and there were also no significant differences in the quality and physical properties of leather produced from the skins of treated and untreated groups, indicating that topical eprinomectin has no deleterious effects on the leather quality of calf skins.
