RESEARCHES REGARDING THE AGE INFLUENCE ON CHINCHILA FEMALE RABBITS BREEDING PERFORMANCES

Elena Costachescu, G. Hoha, Angela Gavrilas

Abstract
Our researches were made on 3 groups of Chinchila female rabbits with ages between 7 and 12 months old. We had in view their age on their breeding performances as well as on the breeding of young rabbits after 2 bringing in succession. We also computed the correlation coefficient between the characters we had in view. We noticed differences among the experimental groups, although they were not significant. Good results were noticed at the 7 month-old female rabbits and at the second bringing. The correlation between the age of the females and their characters noticed by us had negative values for the weight of the nest at the moment of bringing forth (r =0.453) and positive for the number of the weaned young rabbits (r = +0657).

Key words: rabbits, age, performances, bringing
