The pregnancies of queens are not always desirable by their owners, who use hormonal contraceptive and surgical methods (ovariohysterectomy - OSH). Another form of contraception used in human medicine is the tubal oclusion, which consists of mechanical occlusion and / or partial resection of this structure (partial salpingectomy). This research had the objetive of a develop a technique for definitive contraception in pregnant queens, that would not compromise the current pregnancy, the birth of kittens, and the concepts, considering that is common in castration campaigns the visualization of gravid uterus during the approach to abdominal cavity. Another objective was evaluate weight gain and changes in behavior of queens submitted to partial salpingectomy, comparing them with those submitted to OSH, and to compare the time between both surgical procedures. Were used 40 queens, divided into two groups of 20 animals, A: Partial salpingectomy, and B: OSH. The group A, was divided in A1, containing 10 queens pregnant and A2 containing 10 non-pregnant. During the surgery were recorded the quantity of embryonic vesicles found, and the execution time of both procedures. All animals were assessed with seven, 60, 180 and 365 days, being observed initially the maintenance of pregnancy and the occurrence of fetal resorption in group A1, and fertility, weight gain and behavior change in all groups. The mean operative time of group A was 353 seconds, with a deviation of 58.476 seconds, and group B corresponded to 448 seconds with diversion of 84.609 seconds, showing statistically significant difference (p = 0.000069) between the groups on the Mann-Whitney test, with significance level of 5%. The gestacional course and birth of kittens were normal in queens of group A, not occurring abortion neither dystocia. A total of 51 embryonic vesicles were visualized during surgery, 49 born live fetuses, no stillbirths, and no fetal withholding, occurring two (3.92%) 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. Group B showed average weight increase of 20.34%, statistically significant (p = 0.000062) on the Wilcoxon test at a significance level of 5%, while the A2 group showed an increase of 9.57%, considered not significant (p = 0.130570) compared to pre-surgery weight.Regarding the behavioral parameters, group B showed increase in food intake in 60% of the animals, lethargy in 65%, and decreased waking period in 75%, whereas these parameters remained unchanged in most animals of group A. It is concluded that partial salpingectomy 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.
