First of all, it was caused by improper feeding and management in summer. Hot summer weather, male and female feed intake decreased or refused to feed, malnutrition, physical decline. The production of male rabbit spermatozoa (from a spermatogonium to a mature spermatozoa) takes 30-45 days. During the maturation of sperm, in case of high temperature, the rabbit's body temperature is high, and the temperature of the scrotum is high, sperm cannot develop normally. , resulting in a large increase in dead sperm or deformed sperm, greatly reduced sperm motility. At this stage, many rabbit farms stopped mating, but they neglected feeding and management of rabbits. One-sided thinking that this stage, rabbits do not breed, do not need to feed so good or make do with feed. As a result, male rabbits have poor sperm quality, and female rabbits have poor nutrition (no estrus or low conception rates). The sperm released by the male rabbit at the end of September and October is the sperm produced in August-September, and it is the hottest weather at this time. Therefore, it is reasonable that autumn rabbits do not have estrus or infertility. This is also the main reason why many rabbit farms can only reproduce 5-6 nests a year. Second, the rabbits in the fall have entered the hair replacement phase and need to consume a lot of nutrients, especially proteins and vitamins. Hair replacement is to prepare for the winter, remove the sparse autumn clothing into a strong winter clothing, to withstand the cold, so the change of hair will inevitably affect the impact of the fall.
