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

Rezumat
Cercetarile au fost efectuate pe 3 loturi de femele din rasa Chinchila avānd vārste cuprinse īntre 7 si 12 luni. S-a urmarit influenta vārstei acestora asupra performantelor de reproductie si de crestere a produsilor obtinuti īn urma a doua fatari consecutive. S-a calculat si coeficientul de corelatie dintre caracterele urmarite. Au fost observate diferente intre loturile experimentale, desi acestea nu au fost semnificative. Rezultate bune au fost obtinute la femelele īn vārsta de 7 luni si la a doua fatare. Corelatia dintre vārsta femelelor si caracterele studiate a avut valori negative pentru greutatea cuibului la fatare (r=-0,453) si pozitive pentru numarul puilor īntarcati (r=+0657).
