Most goats exposed to males in confined conditions have short ovulatory cycles. The frequency of these cycles can be reduced with a progesterone treatment prior to the introduction of males. The objective of this study was to determine whether extensive management conditions modify the frequency of short ovulatory cycles in progesterone-treated does exposed to photostimulated males. One group of does remained in extensive management conditions and grazed daily from 10:00 to 18:00 h; two other groups were confined separately in shaded pens, and fed alfalfa hay. In March, females from the grazing group (n = 45; grazing-P4 group) and those from one confined group (n = 45; confined-P4 group) were treated with 25 mg of progesterone by intramuscular injections 48 h before joining with photostimulated males (n = 3 per group). The other confined group did not receive the progesterone treatment and was exposed to two photo stimulated males (n = 25; confined-control group). Does were exposed to males for 45 consecutive days. Determination of whether ovulations occurre were made by quantifying plasma progesterone concentrations after introduction of males. The proportion of does that had ovulations at least once was not different between groups (>= 98%; P > 0.05). The proportion of does that had short ovulatory cycles differed between groups (P < 0.001), and this proportion was greater in the confined-control group (76%) than in confined-P4 (27%) and grazing-P4 groups (25%; P < 0.001). It is concluded that extensive management conditions do not modify the frequency of short ovulatory cycles in progesterone-treated does exposed to the photo-stimulated males.
