The effectiveness of synchronization of sexual hunting of goats in industrial conditions with the use of intramuscular administration of progesterone in combination with cloprostenol and HCG has been studied. The work was carried out on the basis of Tverskoy Urozhod LLC (Tver region, Bezhetsky district), a breeding stock of goats (n=422) was used. To reduce the cost of treatment, drugs of domestic production were used: progesterone (BioFarmGarant LLC, Russia), cloprostenol (Magestrophan, Mosagrogen JSC) and GSHK (Follimag, Mosagrogen JSC). A high synchronizing effect of the scheme was established - 95.26% of the animals went hunting within 24-72 hours after the end of processing. Fertilization was 82.34%, fertility was 218.12%. The number of multiple laminations was 78.18%. The average duration of pregnancy was 150.1±0.22 days.
