Today, we mainly study the estrus observation and reproduction technology of rabbits to see how to make rabbits reproduce smoothly. Let's start with the key points of rabbit oestrus observation and feeding techniques.
1. Oestrus observation
The oestrus behavior of female long haired rabbits is mainly characterized by hyperactivity and hyperactivity, like running and jumping, pawing, stepping on the ground, loss of appetite and eating less, which is commonly known as "causing circles". Female rabbits with strong sexual desire will flirt with male rabbits and climb over, and even climb over their own young rabbits or other female rabbits.
When the male rabbit is chasing and crawling, the hindquarters of the estrous female rabbit are raised to meet the mating action of the male rabbit, showing a willing attitude to accept mating. The above oestrus usually lasts for 3 to 4 days. Generally, according to the number of breeding rabbits, production performance, season and feed supply, and comprehensively considering the breeding time and number of rabbits, the development of a detailed breeding plan is the basis for ensuring that meat rabbit production can achieve good economic benefits.
2. breeding technology
1. artificial assisted breeding. Artificial assisted breeding can be selected in a planned way to avoid inbreeding and random breeding; The breeding time of male rabbits can be reasonably arranged to prolong the breeding period. Service life; It can effectively prevent the spread of disease. General rabbit farms (households) mostly adopt this scientific breeding method. If the female rabbit is in estrus and does not accept mating, compulsory assisted reproduction measures can be taken. That is, the operator holds the female rabbit's ear and neck skin with one hand to fix the female rabbit, extends the other hand to the lower part of the female rabbit's abdomen, raises the hips, fixes the tail with the index finger and middle finger to expose the vulva, and allows the male rabbit to climb over and mate.
2. artificial insemination. The great advantage of artificial insemination of long hair rabbit is that it can make full use of excellent male rabbits, so as to speed up the genetic process, improve the quality of rabbit population, and quickly promote good varieties. The key to the success or failure of artificial insemination in rabbits lies in the quality of semen, the stimulation of ovulation in female rabbits and the accuracy of the insemination site. When inseminating, the inseminator must be inserted into the back of the vaginal wall, with a depth of 6 ~ 7 cm. It passes through the urethra and injects semen into the vicinity of the two cervical openings to make the sperm enter the two wombs. From the cervix. In order to achieve better results in rabbit production, it is very necessary to formulate a reasonable breeding plan.
