Rabbit breeding technology

Rabbit reproduction is its necessary stage, what is the performance of the rabbit at this stage? What is the breeding technique of rabbits? Here is the information sorted out by the editor. Let's take a look at it together:

Rabbit breeding technology

1. Sexual maturity and first mating month age, the reproductive index of Rex rabbit under normal feeding management and normal nutrition conditions is: male rabbit sexual maturity is 3-3.5 months old, but the first mating age is not less than 4-5 months old, the weight must be more than 5 jin, female rabbit: sexual maturity 3-3.5 months old, first mating can not be less than 4 months old, the weight must reach more than 4.5 jin. Before they can breed and breed.

2. The oestrus cycle, estrus performance and the best mating time of the female rabbit. The oestrus cycle of the female rabbit is 8-15 days, and each estrus will last 2-3 days. Estrus is a manifestation of the sexual excitement and mating desire caused by the sexual maturity of the female rabbit. The performance of estrus is as follows: female rabbits are active and restless, love beating, loss of appetite, gnawing cages, active climbing. Generally, the situation of oestrus can be identified from the genitals of female rabbits, and the pubic mucosa can be seen as pink in the early stage, bright red in the middle stage, and purplish red in the late stage, and the best mating period is in the middle of estrus, that is, pink early, purple late, and bright red at that time. Practice has proved that there is no certain rule in oestrus of female rabbits, so breeders should check their genitals frequently to avoid missing the period of estrus.

Mating methods of rabbits

① natural mating, put the female rabbit in the male rabbit cage, when the male rabbit crawls across, the female rabbit raised its tail to cater to the mating, the male rabbit turned to one side, issued a cooing sound and scratched its feet, as a sign of mating, wait for it to die for 2-3 minutes, gently catch the female rabbit, pat its buttocks upside down and put it back into the original cage. 6 hours later, the same male rabbit is used to mate again, and the mating record can be made.

② artificial mating, when the female rabbit in estrus comes into contact with the male rabbit, does not want to raise the tail to cater to the male rabbit, the male rabbit can not mate, can take artificial assistance, that is, tie the tail of the female rabbit, pull it forward from the back, hold the ear, neck and string with one hand, and extend the other hand to the lower abdomen and hindlimb of the female rabbit, and lift the arm slightly so that the male rabbit can climb across. After mating, the male and female are separated.

Reproductive characteristics of rabbits

1. The reproductive characteristics of rabbits.

① matured early, and physical maturation was not synchronized with sexual maturation. The well-developed adult rabbits showed oestrus at the age of 4 months, but did not reach physical maturity at this time. It usually reaches physical maturity 1-2 months after sexual maturity, or when the body weight reaches more than 80% of the adult body weight. Under the same feeding conditions, the first mating age of male rabbits should be more than one month later than that of female rabbits (because the sexual maturity of male rabbits is about one month later than that of female rabbits).

② stimulates ovulation. Rabbits belong to mating stimulating ovulation animals. There are many follicles at different developmental stages in the ovaries of mature female rabbits. The follicles mature continuously, but the mature eggs are not actively excreted during estrus. It takes stimulation (mating of male rabbits, mutual climbing of female rabbits, etc.) to expel mature eggs. Female rabbits usually ovulate 10-12 hours after stimulation.

③ twin uterus. The rabbit is a diuterine animal, and the two uterus are opened in the vagina together and become pregnant respectively.

The pregnancy period of ④ is short. The pregnancy period of rabbits is short, the pregnancy period is 29 to 34 days, usually 30 days.

⑤ sexual activity pattern. The temporary activity was the strongest at 1 hour before sunrise, 2 hours before sunset and 1 hour after sunset.

The breeding years of ⑥. Generally speaking, male rabbits can be used for 2-4 years, and female rabbits can be used for 2-3 years.

two。 The estrus characteristics of female rabbits.

The estrous cycle of ① is not fixed and the characteristics of estrus are not obvious, so it is easy to miss the best mating period.

② is easy to estrus in spring and autumn, and the mating rate is high.

The estrus of ③ is better after delivery and weaning, and it is easy to succeed in mating.

3. Estrus identification.

① observation method. Estrus is judged according to the changes of mental state, behavior and reproductive tract of female rabbits. Estrus female rabbits show sexual hyperactivity, run and jump restless, and then further check their vulva, if the mucous membrane is moist, red and swollen, you can confirm oestrus.

② emotional test. When the female rabbit to be identified was put into the cage of the male rabbit with the vas deferens tied, the female rabbit was considered not to be in estrus when she escaped the rejection, and it was identified as estrus to cater to the climbing span of the male rabbit.

Rabbit breeding technology

1. Rabbits are herbivorous, so it is necessary to provide unlimited hay of Gramineae. Some oatmeal or molars can also be added to the feed.

For the sake of balanced nutrition, don't just feed the rabbit, try to eat some fresh and pollution-free vegetables after 6 months old, such as hollow cabbage, celery, Qingjiangcai, sweet potato leaves, carrots and so on. The specific amount should be determined according to the physical condition of the rabbit, but it is best not to overdo it. As the rabbit detoxification function is poor, it is best not to contain pesticides, should be thoroughly cleaned, after washing, put in a ventilated place to dry for 1-2 hours, do not expose to the sun, and then wipe the remaining water with kitchen paper towels.

3. It should be noted that vegetables are different from fruits, and fruits are not recommended for rabbits. Because fruit is a burden on the rabbit's stomach and teeth. If you have to supply, please do not exceed 1-2 tablespoons a day.

4. Necessary supplies for raising rabbits: upside-down kettle with balls, utensils, rabbit toilet, tooth grinding stick, grass rack, rabbit cage

5. Essential drugs for raising rabbits: lactase and coccidiosis.

How to improve the fecundity of breeding rabbits

1. Choose healthy and disease-free female rabbits with strong sexual desire, good motherhood and good development of reproductive organs. It is best to choose from among the 3-5 births of fine female rabbits. Generally speaking, the most suitable breeding age for rabbits is 1-3 years old, and it is not suitable for breeding except a few excellent breeding rabbits over 3 years old.

2. Provide full-price diet to meet the nutritional needs of breeding rabbits, so as to reduce embryo death and abortion and improve the fecundity of breeding rabbits. The sudden sound in daily management can easily cause panic in rabbits, which can lead to miscarriage or decreased libido of pregnant rabbits.

3. Arrange the mating season and mating time according to the heat preservation and cooling facilities and the local climatic conditions. The practice shows that the temperature of the general rabbit house is more than 10 ℃, and the suitable temperature is 15-25 ℃. Therefore, the conception rate and litter size of female rabbits are the highest in spring and autumn. The best time for mating is in the middle and later stages of estrus. In addition, there is also a timely problem on the day of mating. It is better to mate early and late in summer and at noon in winter.

4. Female rabbits are irritant ovulatory animals, which are stimulated by mating of male rabbits, so they should be mated again at intervals of 8-10 hours after the first mating, that is, repeated breeding. A female rabbit copulates with two male rabbits at intervals of no more than 20 to 30 minutes, which is called double breeding. By using repeated breeding or double breeding, the conception rate of female rabbits can be increased by 10% to 20%, and the litter size can be increased by 1% to 3. In addition, female rabbits without estrus or refusing to mate for a long time can increase the number of contact with male rabbits, through chase, hip climbing stimulation, induce female rabbit sex hormone secretion and improve the chance of conception.

5. The condition of feeding and management is good. When the female rabbit is very strong, the breeding intensity can be improved by frequent or semi-frequent breeding, and more commercial meat rabbits can be produced to improve economic benefits. It is generally believed that intensive breeding can be carried out for commercial rabbits, but not for breeding rabbits. Half-frequency reproduction refers to the mating of female rabbits within 12-15 days after delivery, which can shorten the breeding interval by 8-10 days and increase the number of 3-4 births per year.

6. Strengthen the hygiene and epidemic prevention measures in the rabbit house to put an end to the occurrence of diseases. Often clean the rabbit house, observe the rabbits frequently, after the disease occurs, the sick rabbits will be isolated and treated immediately.

Matters needing attention in raising rabbits

1. The living environment of rabbits should be hygienic, dry and ventilated. If the environment is moist and unsanitary, it is easy to breed bacteria and cause skin diseases of rabbits.

2. It is recommended that young rabbits go to the hospital to check for coccidiosis instead of feeding coccidiosis indiscriminately. Coccidiosis occurs in acute. Although many young rabbits die of coccidiosis, there are not a few rabbits poisoned by coccidiosis.

3. If the cage in which the baby rabbit lives is a dog cage, a wooden board should be added to the cage to pad his feet. If he does not pad his feet for a long time, he will get foot dermatitis, which is very difficult to cure.

4. If the rabbit eats vegetables and causes diarrhea, it should be given 4 tablets of lactase in time. If there is no lactic enzyme at home, you can also feed lactic acid bacteria tablets and probiotics.

5. The rabbit's teeth are infinitely long. Prepare a grinding stick for it. Some rabbits like to bite wires and so on, which should be paid attention to. Rabbit supplies should be cleaned and disinfected regularly.

6. Caged rabbits should be active for more than 1 hour every day.

7. If you are afraid of pulling a rabbit, you can teach it to go to the toilet. Its urine and feces should be cleaned every day. If it is not cleaned, nitrogen will be produced when it accumulates for a long time.

8. The baby rabbit should not give it a bath. The rabbit loves to be clean. It licks its own hair every day, and it is not recommended to give it a bath, but when it is not necessary to take a bath, choose to wash it when the weather is fine and sunny. You should also avoid water from entering its ears. If you don't pay attention, it will get otitis media, and you can't give it something like shower gel, soap and so on. Dry it immediately after taking a bath. Or you'll catch a cold.

9. The rabbit does not feel full. It is necessary to control its food intake so as not to die.

Rabbits should not eat too much starch. Starch is very bad for rabbits.

11. Never catch the rabbit's ear when catching the rabbit. The ear is an important organ of the rabbit. The rabbit does not have sweat glands and must use the ear to dissipate heat. The rabbit's ear is not long for people to scratch. If scratching the rabbit's ear causes nerve injury, it will cause the rabbit's ear to be unable to straighten up and cannot turn. The correct way to catch a rabbit should be to hold the rabbit's back with one hand and carry the rabbit's ass with the other hand so that the rabbit's legs and belly are facing forward.

All stages of the aquaculture industry are very important, first select the species, then raise it, go through the breeding period in adulthood, then give birth to cubs and continue a new round of feeding. It has a good breeding prospect.
