VETERINARY IMPLANTED RETARD DRUG FOR IMPROVING PRODUCTIVITY OF FARM ANIMALS (VERSIONS)

摘要

FIELD: medicine, veterinary science.;SUBSTANCE: invention refers to agents of veterinary medicine and can be used in fur farming and animal husbandry for improving young growth liveability and productivity of animals. A new veterinary implanted retard drug for improving productivity of farm animals contains active substances: melatonin or melatonin and ximedone, a biodegradable polymer base and processing aids; and said biodegradable polymer base is presented with interpolymer complexes of polymethacrylic acid and polyethylene glycol ("КПН"-1) or interpolymer complexes of polymethacrylic acid and polypropylene glycol ("КПН"-2) in a certain ratio. The processing aids are lactose or microcrystalline cellulose or their mixtures in the ratio (wt %) 50:50. Said "КПН"-1 or "КПН"-2 used as the polymer base allows introducing up to 25% of ximedone into a dosage form of said veterinary drugs that essentially improves their effect, and reducing their cost in 1.5-2 times in comparison with a prototype.;EFFECT: application of the veterinary drugs containing melatonin and "КПН"-1 or "КПН"-2 bases in fur farming with using an accelerated technology of mink farming ensures liveability of a mink livestock to the slaughter period with reducing farming time by 1,5-2 months and gain in fur production of the area exceeding the untreated animals by 15-20%.;8 cl, 2 tbl, 38 ex
