The aim of this study was to evaluate the effect of Altrenogest as a method for synchronization of estrous in gilts. The synthetic progesterone Altrenogest was fed daily to 123 nrs. gilts at 20 mg/gilts for 18 days. Gilts were checked for oestrus twice daily and were artificially inseminated. One hundred and seven gilts came in estrous between 3 and 7 days - 5,22±1,42 after withdrawal of Altrenogest. The farrowing rate was 74,92 % and average litter size was 12,06. The piglet index was 903,53. Altrenogest, the active ingredient in ALTRESYN® is effective for regulating the estrous of cycling gilts in commercial pig farms.
