A study was conducted to examine the response of ovaries in sows receiving gonadotropin (PMSG, hCG) during treatment with Altrenogest. Nineteen sows just after lactation were randomly assigned to the following four groups. Group 1: Altrenogest (-), PMSG (+) hCG (+); Groups 2 and 3: Altrenogest (+), PMSG (+), hCG (-); Group 4: Altrenogest (+), PMSG (+), hCG (+). The sows were subjected to laparoscopic examination on the fifth day after PMSG injection in Group 2, and between eight and ten days after PMSG injection in the other groups.<br>(1) All the sows in Group 1 exhibited estrus, whereas strong estrus was not recongnized in any of the sows in Groups 2, 3 and 4.<br>(2) Corpora lutea were induced in all the sows in Groups 1 and 4 (32.8±11.8, 24.0±7.4), and at the same time eggs were recovered in all the sows (23.8±13.7, 18.3±7.6). Three out of four sows in Group 2 had large follicles (21.7±6.5), although the sows in Group 3 had neither corpora lutea nor large follicles.<br>The sows injected with only PMSG during Altrenogest treatment did not ovulate even though they showed follicular growth. However, ovulation was induced during Altrenogest treatment in sows injected with PMSG and hCG. These results indicate that Altrenogest treatment does not interfere with the follicular ability to respond to exogenous gonadotropins (PMSG, hCG).
