Resumen:
In captive chinchillas, one of the most challenging behavioral problems is the development
of a stress-related abnormal repetitive behavior (ARB) known as ??fur-chewing??. We investigated
whether there is a relationship between the severity of fur-chewing behavior and
reproductive function in male and female chinchillas. Regardless of the severity of abnormal
behavior, fur-chewing males did not show significant differences in seminal quality (sperm
concentration, motility and viability; integrity of sperm membrane and acrosome) and the
response to the process of semen collection (the number of stimuli needed to achieve
ejaculation) when compared to those with normal behavior. Also, females showing normal
or fur-chewing behavior presented similar reproductive performance in terms of number of
litters per female per year and litter size. However, pup survival rate was lower ( p = 0.05) in
fur-chewing females than in normal females. These results seem to be consistent with data
suggesting non-significant effects of ARBs on reproductive performance.
