Effect of reproductive rhythm on the ovarian status and performance of rabbit does

The efficiency of a rabbit farm is affected by many factors but the most important of them is the reproductive rhythm. In Italy the widely used production system implied the artificial insemination (AI) of does at 11 days from kindling. This protocol is well adapted to cyclization, however at time of AI, sexual receptivity is not particularly high and synchronisation hormones have often to be used to reach a satisfactory fertility rate (Castellini and Boiti, 1999). In fact, sexual receptivity in rabbit does is very high immediately after kindling, and receptivity increases only after weaning (Theau Clèment et al., 1990). In intensive farms, since reproductive activity is uninterrupted, such rhythm is too stressful and the theoretical advantages are strongly reduced by the excessive exploitation of does...
