Pre-species immunization:
The first is prevention of canine dysentery, subcutaneous injections of diarrhea dogs and hot dogs, 1 ml each, and the immunization period is 6 months.
The second is antiviral enteritis. Inactivated vaccines are cultured in tissue culture with virulent enteritis. Each immunization with 1 ml subcutaneously is performed. The immunization period is 6 months. It is advisable to use one injection needle to prevent infection. Pre-harvest nutrition: As the winter solstice season begins to increase sunshine, the genitals of leeches begin to develop, the scrotum of the male scrotum droops, the testicular volume increases significantly, and the sperm begins to develop. The number of primordial follicles in the ovary of females increased, and follicles also increased significantly. The uterus was enlarged and hypertrophied. Therefore, nutrition should keep up with the physiological needs, in addition to ensuring animal protein, vegetable protein, but also increase vitamins, especially fat-soluble vitamins, such as VA, VE, can be added to the feed VE tablets, carrot or peanut oil and VC tablets to Promote the normal development of reproductive organs.
Grasp the timing of estrus:
(1) The public estrus period is January-March, and the normal public money remains in the state of courtship and is interested in the mother-in-law. After more than 12 hours of equinox sunshine, the testicles began to shrink and degenerate.
(2) There may be 2-4 cycles of estrus in females, and the cycle may be divided into four periods, ie, the early period, the estrus period and the off-season period. Each cycle is about 6 days to 10 days, and the duration is 1 day to 3 days. The rest period is 5 days to 6 days. There are no mature follicles in the mother's ovary during solitude, and no mating is accepted, and forced mating will not conceive. Therefore, we must seize the observation of estrus, after the mating in the breeding season for re-use or cycle of re-equipment, to ensure high fertility rate.
Grab the mating date:
(1) The end of February and early March are the most prolific breeding seasons for leeches, and the dates of mating should be arranged according to the number of males.
(2) Most females should adopt the initial allocation, that is, the first breeding season. The period from mating to breeding is approximately 5 days to 7 days. At the same time, young male volunteers are trained to participate in breeding, semen quality is identified, and good quality species are selected.
(3) In the breeding period of about 10 days to 12 days, the first maternal cricket will be re-used once and the breeding period will end.
(4) Supplementation is performed for newly-prepared non-pregnant cockroaches, and the replacement period is approximately 5 days after the end of the mating season. For those females who still have estrus performance and doubt about not having a pregnancy or a fake female partner, they may make supplements during this period and adopt a continuous supplementation method, that is, the first time every other day. Every mother-in-law is pregnant and her farrowing rate is high.
