In goats, estrus synchronization is commonly performed with vaginal sponges impregnated with fluorogestone (FGA) (FERNANDEZ-MORO et al., 2008; FREITAS et al., 1996) or medroxyprogesterone acetates (MAP) (FONSECA et al., 2005; LEHLOENYA et al., 2005), or using controlled internal drug release (CIDR) devices impregnated with progesterone (AMORIM et al., 2008; MENCHACA et al., 2007).
To reduce the cost of using CIDR for estrus synchronization, this study evaluated the effectiveness of using the same CIDR up to three consecutive times in the reproductive performance of dairy goats raised in the semi-arid zone of northeastern Brazil.
The does were allocated into three consecutive estrus synchronization treatments: In CIDR1x (n = 15), the females were treated for nine days with a new CIDR vaginal device (Eazi-Breed CIDR[R], InterAg, New Zealand) containing 0.3 g progesterone.
CIDR implants were placed in the treatment group when the second blood sample was taken.
The CIDR implants were removed the next day (day 9), and both groups were observed for estrus behavior for 1 hour, twice daily, for 7 days.
The ages and weights measured throughout the study were compared between the CIDR and control groups as well as between prepubertal and postpubertal heifers, using a one-way analysis of variance with a Bonferonni correction for multiple comparisons.
As expected, animals from the PSP group showed a significant increase (P<0.05) in total bacteria count in comparison with the other groups, with counts for the use of OB[R] being similar to the CIDR group (Figure 1).
The degree of local inflammation (vaginitis) was generally minor in the CIDR group, with all animals from this group having no adherence, considered as degree (-), showing neither resistance during the device removal nor significant accumulation of purulent and/ or fetid vaginal
The temporal onset of estrous in the CIDR group was more disperse than the others groups (Figure 2).
