Castração química de cães por meio do uso do gluconato de zinco associado ao dimetilsulfóxido.

Abstract

As semi-domiciled, stray and abandoned dogs populations represent OR hum Problem of Public Health and Welfare Animal Worldwide. Therefore, the present work aimed to evaluate the time reduction occurred while zinc gluconate action to associate when Dimethyl sulfoxide, for that dog was considered sterile, through the application of medication in the epididymis tail. Were used 10 male, divided into two groups, checking and testing that went through a period of adaptation before making the top of the collections. Were evaluated as amendments seminal parameters in testicular ultrasonography and histopathology and carried out measurement of blood cortisol, paragraph evaluation of stress. The results obtained were submitted statistical to testicles ANOVA and Tukey with p <0.05. Within the test group, there was reduction of seminal physical characteristics and Significant increase (p <0.05) of the sperm pathologies. As major injuries found in histopathology were edema, bleeding, degeneration degrees in miscellaneous, lymphoplasmacytic departed general way and necrosis, featuring the irreversibility of the process. Were observed changes not ultrasound examination showed difference between how statistics average (p <0.05 ) in all days, when compared the control group and the test group, validating that half as diagnosis paragraph changes assessment short rhythm space. In relation to the measurement of cortisol levels was not found significant changes, with the values within the normal range. Injection solution with a zinc gluconate base 2.62% + 0.5% DMSO in the epididymis tail, was effective on cause of subfertility dogs, except for hum of animals that was 21 days after application returned to regular patterns semen.
