There are many factors that influence conception rate. Sterility, extreme age, poor physical condition, pseudopregnancy, poor genetic quality, sore hocks, injuries, retained fetuses, and disease are among the most important factors. Pay special attention to the physical condition of the doe. If she is too thin, you are probably underfeeding, or if she’s too fat, you’re overfeeding. Both conditions have negative effects on reproduction. Intensive breeding (on a 14-day or less remating schedule) can cause a doe to lose weight and condition, thus reducing her ability to conceive.
