[Hygienic substantiation of using new antibiotic preparations, tylosin phosphate and vitagrin as food additives].

Hygienic regulation of the use of the agents studied in animal experiments as food additives has been validated with respect to the dose level, regimen of addition and the period of waiting for slaughter. It is recommended that tylosin-phosphate should be included into the animals' ration as a food additive in a dose of 60 mg/kg for a short time (2-3 days), the period of waiting for slaughter being not less than 6-7 days. Addition of vitagrin has been recommended for young growing animals in a dose of 400-500 g/ton of feed. The dose of vitagrin should be reduced to 200-300 g/ton of feed one-two months before slaughter, with a 10-day period of waiting for slaughter.
