Tips for breeding rabbits

The traditional breeding is to catch the estrus female rabbit to the male rabbit cage, let the male rabbit climb over, hear the male rabbit grunt, see the male rabbit fall down from the female rabbit, immediately catch the female rabbit out of the cage, slap the female rabbit on the ass, and put it back into the female cage immediately. What is the reason why the conception rate of this method is very low? According to my observation, after each mating, the female rabbit had the habit of urinating immediately. The urination washed away part of the semen and reduced the chance of giving birth, while the female rabbit was left in the male rabbit cage for 7 to 10 minutes. The female rabbit was so scared that the female rabbit did not dare to urinate and put an end to the outflow of semen. In addition, the male rabbit mated 2 or 3 times in a row in a few minutes, without having to repeat every 6 hours, saving time. At present, the conception rate of our department is more than 70%. A little humble opinion, for your reference!
