SUMMARY This experiment was conducted in order to compare the effects of injecting PGF 2 α alone, PGF 2 α with oxytocin and placebo on the induction of farrowing in swine and to compare the relative effects of 3 different dosages of oxytocin (10, 20 and 30 iu per animal) when combined with PGF 2 α (10 mg). The findings revealed that animals treated with 30 iu oxytocin farrowed within 10.6 h which was similar to those receiving PGF 2 α only (9.4 h), but shorter than control animals (53.6 h). Animals receiving 20 and 10 iu of oxytocin farrowed within 1.4 and 1.7 h, respectively. Difficult farrowings requiring manual assistance occurred in 30%, 30%, 50% and 10% of sows given 30 iu, 20iu and 10iu of oxytocin and in the control group, respectively. Thirteen of 73 sows treated with PGF 2 α farrowed within 12.6 ± 5.3 h. Stillbirths were highest (10.2%) in the control animals whilst in the others it was under 7%. Oxytocin at dosages of 20 and 10 iu, seemed most promosing in terms of synchronising farrowing following PFG 2 α treatment in swine. However, farrowing complications were more common in these groups.
