INJECTION PREPARATION FOR HIGHER SPERM PRODUCTION IN FARM BREEDERS AND COCKS, AND METHOD FOR USING IT Russian patent published in 2013 - IPC A61K39/385 A61K9/42 A61K38/31 A61P15/08 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to biotechnology, more specifically, to using a chimeric somatostatin-containing protein for improving the reproductive properties of male farm animals and cocks, and may be used in veterinary science. The injection preparation is used in the form of a chimeric protein suspension with water-insoluble enzyme-inactive chloramphenicol acetyltransferase with no 10 C-terminal amino acids, amino acid spacer (Sp)n, wherein n=1, 2, 4, 8 and somatostatin-14 with AGCFWKTFTSC amino acid sequence in the refined vegetable oil with bee wax added at 250-1000 mg of the above chimeric protein per 100 ml of the refined vegetable oil containing 0.9-1.1 wt % of bee wax. The injection preparation is used in cocks and farm animals after achieving the physiological maturity at 50-200 mcg of the protein per 1 kg of a live body weight.

EFFECT: invention enables increasing sperm production: increasing the ejaculate volume and reducing the biologically damaged sperm in farm animals and cocks by using the preparation for injections with a low-reactogenicity adjuvant.
