The method of improving the reproduction rate of porcupine

1. Compound breeding method

Six hours after the female porcupine was mated by the male porcupine in the same breeding pond during the peak estrus, the female porcupine was put into a spare boar breeding pond to accept the second mating. After that, the pregnant sows are raised separately until they give birth. It should be noted that the male porcupine used in the compound breeding method is not only not related to the female porcupine, but also preferably grew up with the female porcupine and can be close to each other, in order to avoid possible fights between male and female porcupine. The results showed that although the annual litter number of sow porcupine was the same as that of single breeding, the average litter size of each sow was 1 more than that of single reproduction, and the reproductive efficiency was significantly improved.

2. Blood matching and breeding method

The female porcupine is in estrus within 1-3 days after giving birth, and the female porcupine can accept the male porcupine and mate with it. Therefore, we can make use of this characteristic of the female porcupine and adopt the method of blood breeding. The method is that within 12-48 hours after the female porcupine gives birth, the porcupine is put into the breeding pond of two male porcupine respectively to mate with them. the two male porcupine are not closely related to the female porcupine, and it is best to grow up with the female porcupine and be close to each other, otherwise, the male and female porcupine may fight each other. The first mating took place within 12-24 hours after the sow gave birth, and the second mating took place within 25-48 hours after the sow gave birth. The interval between mating is 12 hours. The time for male and female porcupine to mate in a pool is 1 hour. After mating, the female porcupine is put back into the original feeding pond to continue to breast-feed the young. The results showed that by using the blood breeding method, the sows produced an average of 1 litter more per year than the combined breeding method and the single breeding method, 2 more litters per year than the combined breeding method, and 3 more litters per year than the single breeding method, and its reproductive efficiency was significantly improved.

III. Drug aphrodisiac method

Because the female porcupine has the ability of estrus all the year round, after the piglet weaning, the sow porcupine can be fed with estrus drugs to promote the female porcupine to estrus early and shorten the empty time. In order to reduce the residue of aphrodisiac drugs and reduce the side effects of aphrodisiac drugs on porcupine, it is best to use Chinese herbal medicine to promote estrus. For aphrodisiac Chinese herbal medicine, you can go to the veterinary drugstore to buy some ready-made aphrodisiac herbal medicine, such as aphrodisiac powder and so on. You can also prepare some aphrodisiac Chinese herbal medicine. The reference formula is 15% of Angelica sinensis, 10% of Codonopsis pilosula, 10% of meat from Rong, 15% of obscene sheep, 15% of actinolite, 10% of Bajutian, 10% of Chinese wolfberry, 10% of Atractylodes macrocephala, and 5% of roasted hay. Each sow is fed 20-30 grams a day, and the sow begins to be in estrus for about 20 days. Practice has proved that through the method of stimulating estrus with Chinese herbal medicine, the empty time of sows can be greatly shortened, and even the reproductive efficiency of three births a year can be achieved.
