Animal sex control is a bioengineering technology that can significantly improve the economic benefits of animal husbandry. In the production of long-haired rabbits, the female rabbit produces 15-20% more hair than the male rabbit; in the production of rex rabbits, the female rabbit Pipi male rabbit The quality of the skin is good and the price is relatively high. In the production of meat rabbits, the growth rate of female rabbits is 10-15% faster than that of male rabbits. It can be seen that letting female rabbits multiply female rabbits can significantly improve economic efficiency. Some rabbit farms have explored several ways to make female rabbits more female rabbits in breeding practice.
First, the use of male rabbits to mate more times to produce more females, the higher the rate of the characteristics of the male rabbits with continuous mating for 7 days, in the maternal estrus on the first day or the second day of mating. A total of 34 female rabbits were experimentally tested with this method. During the experimental period, female rabbits produced a total of 208 puppies, of which 161 female rabbits accounted for 77.4%.
The second is to strengthen the exercise capacity of the female rabbit. The method of increasing the creatine content of the female rabbit to decrease the intrauterine ph value makes the female rabbit produce more female rabbits. During the estrus period of the female rabbit, it can be placed in a larger activity space to take chase. , toggle and other methods to make it frequent activities, in a state of fatigue, and then carry out mating. In this way, 4 female rabbits were tested and the female rabbits yielded more than 65%.
The third is to add 20 grams of glucose and 50 milligrams of vitamin e per day to the mixed feed of the rabbits 8-12 days before the female rabbits are mated, and stop feeding after the breeding. Using this method of breeding, the number of female rabbits produced is about 12% more than that of male rabbits.
