Thereafter, goats were continuously observed to record the following parameters: parturition, dystocia incidence, placental delivery and kid and maternal survival. Moreover, blood sampling was performed around kidding and plasma progesterone concentrations were analyzed. The interval from injection to parturition (mean +/- SEM) was not significantly different among the experimental groups: 35.1 +/- 1.5 h, 33.3 +/- 0.9 h and 34.1 +/- 1.8 h (groups Cl, L and L(50), respectively). In the control group, time to parturition was 99.4 +/- 12.1 h (range: 34-166 h). All the goats expelled the foetal membranes within the first 2 h after the induction. The incidence of dystocia due to foetal posture was not significantly different between induced and control goats (21.1%, 20.0%, 22.0% and 20%, for groups Cl, L, L(50) and S, respectively). The percentage of live kids was practically similar between induced goats (93.9%, 94.9% and 92.1%, for groups Cl, L and L(50), respectively); in addition, there was a case of maternal mortality in control group (6.7%; 1/15), whereas there was no mortality in induced goats (0%; 0/57). Plasma concentrations of progesterone showed an intense drop (< 2 ng/ml) at 24 h after induction. This study confirms the effectiveness of the luprostiol to induce the parturition in goats, within a narrow range (30-40 h) in most of the induced females (80.0%, 7.5 mg; 77.8%, 3.75 mg).||URI:||http://hdl.handle.net/10553/51551||ISSN:||0936-6768||DOI:||10.1111/j.1439-0531.2007.01001.x||Source:||Reproduction in Domestic Animals[ISSN 0936-6768],v. 44, p. 83-87|
