Variation of sexual behavior of photo-stimulated bucks during the transition from winter to spring in the semi-arid climate of Mexico

Sifuentes L, Peiró M J P, et al.
Experimental design depicting the dates when the photoperiodic treatment was applied to bucks, behavior tests and sampling of plasma testosterone. Bucks were exposed to ovariectomized females during non-breeding period. Bucks were submitted to a treatment of artificial long days (16 h of light and 8 h of darkness) from November 1 to January 15. Afterwards, bucks received the natural photoperiod. Buck sexual behavior was recorded weekly from March 1 to April 26. Blood samples were taken weekly from January 18 to May 31 to determine plasma testosterone concentration.
