Biometria testicular e comportamento sexual de cães da raça Australian Cattle Dog

Abstract

The objective of this study was to analyze the characteristics of testicular biometry and the sexual behavior of the Australian Cattle Dog, allowing greater reproductive knowledge of the breed. Fifteen adult male dogs aged 18 to 72 months were used. The testicles were evaluated for consistency while testicular biometry was performed with the aid of a pachymeter to determine the testicular volume. The libido test was performed through the behavioral observation of the male with the bitch in estrus and its annotated attitudes for determination of pattern. The testicular volume of the animals ranged from 10.4 cm³ to 35.9 cm³ with a mean of 18.2 ± 4.70 cm³. The testicles were elastic and 11 animals showed testicular symmetry. The spermatic concentrations evaluated ranged from 0.25x106 to 2160x106, reaching a mean of 499,315 ± 208.93 million cells / ml of semen. All the dogs had low or high intensity libido and demonstrated sexual behaviors varied according to the influences of the environment, being: approach, research, rhythmic impulses, climbing, climbing by head, climbing by the side, paws on the female body, urination act and preference to external stimuli.
