[Improvement of the rate of conception by the use of PGF2 alpha in the sow one day before weaning].
The authors investigated the influence of PGF 2 alpha on rate of conception in a single large pig production unit. Two groups of sows were selected at random before weaning, forming an experimental and a control group. The groups were treated as follows: Group 1 (experimental group) received a single intramuscular dose of 3 mg Alfaprostol one day before weaning. Group 2 (control group) received a single intramuscular dose of 2 ml physiologic saline intramuscular one day before weaning. The results are evaluated on the basis of parameter "return to estrus". The experimental group showed significant less (p < 0.05) sows returning to estrus than the control. This evidence suggests that the reason of unsatisfactory breeding performance after PG F2 alpha application may be the result of other influencing factors.
