SILVA, Amanda Camilo; SILVA, Camila Elana Santana e; PELUSO, Emília Miranda e TUDURY, Eduardo Alberto. Sterilization in queens by partial salpingectomy (including pregnant) versus ovariohysterectomy. Cienc. Rural [online]. 2012, vol.42, n.3, pp.507-513. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782012000300020.
The tubal occlusion is a form of contraception used in human medicine, which consists of mechanical occlusion and / or partial resection of this structure (partial salpingectomy). In this study, we tried to use a technique for definitive contraception in pregnant queens, that would not compromise the current pregnancy, the birth of kittens, and the concepts, considering the frequency of the visualization of gravid uterus in castration campaigns. Another objective was evaluate weight gain and changes in behavior of queens submitted to partial salpingectomy, comparing them with those submitted to ovariohysterectomy (OSH), and to compare the time between both surgical procedures. Were used 40 queens, divided into two groups of 20 animals, GA: Partial salpingectomy, and GB: OSH. The group GA, was divided in GA1, containing 10 queens pregnant and GA2 containing 10 non-pregnant. All animals were assessed with seven, 60, 180 and 365 days. The surgical times showed statistically significant difference between the groups, with GB slower. The gestacional course and birth of kittens were normal in queens of group GA1. A total of 51 embryonic vesicles were visualized, 49 born live fetuses, and occurring two fetals resorptions. Among the 49 fetuses, seven (14.28%) presented genu recurvatum. With respect to fertility, the animals in group A that cycled and mated, did not get pregnant. Only the Group B showed average weight increase (20.34%) statistically significant. Regarding the behavioral parameters, the group B showed increase in food intake, increase of the lethargy, and decreased in waking period. It is concluded that the technique of partial salpingectomy performed in queens is a 100% effective contraceptive method of rapid execution, which can be employed during the transoperative identification of pregnancy, with minimal adverse effects on fetuses, no significant changes of behavior neither weight gain, but with undesirable characteristics on the acceptance of owners.
