Abstract: The objective of the present study was to evaluate the endocrine and behavioral features of estrous-induced Alpine goats. A total;of 36 nulliparous, 40 non-lactating and 42 lactating does were treated with. intravaginal: 60 mg medroxyprogesterone acetate sponges for 9 d plus 200 IU eCG and 22.5 mu g d-cloprostenol 24 h before sponge removal. Plasma progesterone concentration, was. analyzed from blood sampled on days 0, (sponge insertion), 5, 8. (cloprostenol administration) and 9 (sponge removal): in 11 nulliparous, 13 non-lactating and 11 lactating does. Estrous response did not differ (P > 0.05) among nulliparous (97.2%), non-lactating (90.00%) and lactating does (85.7%). Interval to estrus and duration of estrus did not differ (P > 0.05),among nulliparous (2218 +/- 9.9 and 25.6 +/- 6.8 h), non-lactating (217 +/- 15.8 and 25.0 +/- 6.0 h) and lactating does (22.2 +/- 10.4 and 24.9 +/- 4.2 h). The accumulative percentage of does in: estrus during the first 36 h after sponge removal was 88. 1%. The correlation between interval to estrus and duration of estrus was r = -032 (P < 0.001) Endogenous progesterone production is decreased until day 8 or suppressed by MAP on day 9. Conception rate was greater (P < 0.01):in lactating (77.8%) than non-lactating, (44.4%) but similar (P > 0.05) to nulliparous (60.0%) goats. Estrus can:be efficiently induced:by means of hormonal treatment in goats and acceptable fertility can be obtained regardless of animal: category. (c) 2007 Elsevier B.V. All rights reserved.
