Biolactin-2 preparation containing 5.0 mg of porcine prolactin (pPRL) purified from porcine pituitaries was used to stimulate lactation in sows with periparturient agalactia and in healthy primiparous and multiparous sows. Immunological activity of Biolactin-2 approached that of the PRL standard. It was found that a single intramuscular injection of Biolactin-2 effectively stimulates milk ejection in sows with mastitis-metritis-agalactia syndrom (MMA). Performance of piglets treated with a single or double dose of Biolactin-2 and as well as that of healthy ones was similar. A single administration of Biolactin-2 to healthy primiparous sows on the 1st day after farrowing significantly increased daily body gains of their litter in the first two weeks of life. This effect was not observed in multiparous sows.
