Here, we determined whether the sexually active (SA) male goats can stimulate reproduction in does and males when housed together in the same flock during the non-breeding season, and whether male goats exposed to the “male-to-male effect” can fertilize does with the same efficiency and timeframe as SA males stimulated by photoperiod. In March, one group of does was kept isolated from male goats, while three other groups were housed with seasonally hypoactive males (SH). In April, the isolated group was joined with two SA male goats (SA group), while the other three groups were managed as follows: one group was joined with two SA male goats (SA + SH group); the second group was joined with two SA male goats which were fitted with aprons to prevent mating (SA-apron + SH group); and the third group was joined with two SH male goats (SH + SH group). The percentages of does that kidded did not differ among SA (73 %), SA + SH (70 %) and SA-apron + SH (76)% groups; however, all three had greater kidding rates than the SH + SH group (29 %). We conclude that SA male goats stimulate the reproductive activity in both does and male goats during non-breeding season when housed together in the same group. Furthermore, male goats stimulated by the “male-to-male effect” can achieve fertility rates and fertilization timeframe comparable to those of SA male goats. 000160856 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000160856 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000160856 700__ $$aTejada, Luz María 000160856 700__ $$aLópez-Magaña, Dolores 000160856 700__ $$aMillán-Orozco, Jair 000160856 700__ $$aHernández, Horacio 000160856 700__ $$aMillán-Orozco, Jersson 000160856 700__ $$aBedos, Marie 000160856 700__ $$0(orcid)0000-0003-2827-3054$$aAbecia, José Alfonso$$uUniversidad de Zaragoza 000160856 700__ $$aKeller, Matthieu 000160856 700__ $$aChemineau, Philippe 000160856 700__ $$aDelgadillo, José Alberto 000160856 7102_ $$12008$$2700$$aUniversidad de Zaragoza$$bDpto.
