| Popis: | The objective of the study was to evaluate the reproductive performance and estimate the genetic parameters, in a real environment, of the rabbit of the exotic Hyplus breed. The study will allow appreciating the parameters that could be the object of genetic improvement in view of a selection to produce a more efficient rabbit. The work took place at the SAP Mé d’Adzopé farm from January 2013 to June 2015. One hundred and twenty breeding does were followed for five successive generations of five parities each, with an interval of 11 days between the parturition and the next mating with weaning at 30 days. These females produced 5283 total born rabbits with 5164 born alive and 4732 weaned. The genetic parameters including heritability, genetic, phenotypic and non-genetic correlations (environmental effects) did analyzed using the Derivative Free Restricted Maximum Likelihood program. The results obtained showed that the receptivity and fertility rates did significantly influenced by the order of parity and the season of kindling. The pre-weaning mortality rate was 8.37%. Females had the best prolificacies’ between the second and fourth parity, with an average of 9.9, 10.19 and 9.79 kits respectively. The heritability values of young rabbits total born alive, born alive, weaned and old rabbits were 0.22; 0.20; 0.16 and 0.12 respectively. These results showed that selection is possible for these studied traits. Published by the International Journal of Agronomy and Agricultural Research | IJAAR {"references":["Belhadi SB. 2004.
