When mistakes are made, it is necessary to strictly grasp the estrus time of mothers, to do a good job of breeding leeches in time, and to increase the fertility rate of females. Grasp and hold. Observe carefully and do a good job in the breeding of leeches.
Choose high quality species
The species has black coat, bright luster, less submandibular leukoplakia, and a pair of needles, hairs, and bows. The body is dense and loose. In addition, the ratio of male to female should be appropriate, and the ratio of male to female is generally about 1:5.
Do a good job of mating and breeding
Hydra fertility is very seasonal, depending on regional and climatic conditions, and is suitable around mid-March. Specific control of the following aspects:
Preparation before mating: From December onwards, pay attention to the body condition of the species, use fresh sea fish and lean meat as main ingredients, and supplement vitamins A, D, E, B, etc., so that the species can reach the abdomen flat, body-distributed, muscular Robust, flexible and demanding sexual desire.
Strengthen the stimulation of the opposite sex and increase the sexual desire of the public. From the beginning of February onwards, arrange the male and female cages in a row or insert the cage into a cage on a male cage to invigorate the male sexual desire.
Serious estrus identification was performed to examine the external genitalia and comprehensive judgments were made based on the performance of the activities.
The public embarrassment is irritability and lack of appetite. They often walk around in the cage and make a squeak. The mother estrus is excitable during estrus, and the frequency of urination increases or the cuddling is at the bottom of the cage. Observe that the external genitalia is slightly separated from the external genitalia, the labia congestus, swelling and microeversion, the mucous membrane is white or pink, and white or yellow mucus flows out. This is a suitable breeding period.
Adopting a reasonable breeding method: According to the characteristics of female puerperal estrus, adopt a combination of periodical compounding and dual-periodic compounding methods, that is, in the first two days of a love period, two times a day, and then every 7 days. 8 days again. Each breeding should put a male and female cockroaches together in a cage, and attach a string of 80 centimeters around the tail of the mother cockroach, fix it to the cage wall, and make the female outdoor cockroach easy to mate. The method works very well.
