Abstract: 
A change in the ratio of myometrial .alpha.- and .beta.-receptors during pregnancy in the pig causes .beta.-receptors to dominate at parturition. Epinephrine, when discharged because of stress, causes myometrial relaxation. Consequently, parturition is interrupted and delivery delayed. In a double-blind field trial with 1066 sows, prophylactic treatment with 0.5 mg/50 kg b.w. [body wt] of the .beta.-blocking agent carasolol (Suacron) at the onset of labor resulted in a shortened duration of parturition (P < 0.05), a reduction in the stillbirth rate and in obstetrical complications as well. The incidence of puerperal disorders was reduced in 1st-litter gilts from 20.5% (placebo group) to 9.9% (P < 0.01).
