Obserwacje kliniczne nad przydatnoscia Uterotonic-Polfa w ograniczeniu syndromu MMA u loch

The studies were carried out in an industrial farm consisting of 120 sows and 1239 piglets born to them. The sows selected at random were divided into two groups. Sixty female pigs (group I) were given Uterotonic at a dose of 50 mg of propranolol (10 ml of the solution) per sow. The drug was administered once intramuscularly during parturition or a few hours after its accomplishment. The second group of 60 sows served as a control. In the control group signs of MMA were recorded in 15 per cent of the sows and in the experimental one in 8.33 per cent. The puerperal period in sows receiving Uterotonic lasted 3-5 days shorter than that in the control group. In piglets of the experimental group the signs of diarrhoea were observed in 12 litters (20 per cent) and in the control in 16 litters (26.66 per cent). Mortality in the experimental group was 5.87 per cent in the control one - 8.61 per cent. Better productive effects within 21 days after birth were also noted in the experimental group of animals than in the control one although the difference was statistically nonsignificant.
