Abstract
The aim of this work was to study two reproductive extensive managements, long term applied in an industrial rabbit farm. Rabbit does were distributed in two experimental groups: does inseminated on day 18 pp (EXT18) and weaned at 40 days of lactation and does inseminated on day 25 pp (EXT25) and weaned at 47 days. A total of 33.499 artificial inseminations (AI) were analysed using fresh semen. Fertility and fecundity were similar, although rabbit does of EXT25 group tend to be more fertile in all seasons, except in summer. Kits born alive per AI were also similar, but in spring, a lower number of kits born alive per parturition were obtained in EXT25. Just as we expected, productivity of EXT18 group was higher, with 0.5 more kits sold per parturition, being lower too the difference between the theoretical and real parturition interval obtained. Analysing our results,from a practical point of view, we could affirm that the reproductive system EXT25 can be viable. This system is not detrimental to fertility and allows only one fattening band, so it could counteract the lower productivity, increasing the number of does.
