The aim of the work was to analyse the factors which influenced fertility of chinchilla as well as to compare the fertility of chinchillas of standard, beige and black velvet types. The analysis of variance proved statistically significant influence of the breeder (breeding farm), year, animal age and colour type on the number of born and raised chinchillas. The highest arithmetic means were obtained by beige type: 2.15 of born and 1.83 raised in one litter. Standard type: 2.02 and 1.69, respectively. The lowest means characterized black velvet females. Results of reproduction are to be classified as satisfying. The number of born chinchillas in one litter varied depending on colour type.The results show that the females characterised by higher number of born cubs had also higher number of raised cubs. Coefficients of repeatability of traits of reproduction were low: 0.198 of born and 0.231 of raised. The estimated results were slightly higher than those presented in literature and suggest low but significant influence of genetic base on reproduction results in chinchilla females
