Gilts (n = 267) were allotted to flushing (1.55 kg/d additional grain sorghum), altrenogest (15 mg . gilt-’ d-l) and control treatments in a 2 x 2 factorial arrangement. Altrenogest was fed for 14 d. Flushing began on d 9 of the altrenogest treatment and continued until fust observed estrus; 209 gilts (78%) were detected in estrus. The interval from the last day of altrenogest feeding to estrus...
