At present, in most parts of the country, male and female rabbits are divided into groups or caged (cock) feeding methods. Female rabbits are placed in male rabbit cages during estrus. This method is called artificial assisted mating. It has the following advantages over natural mating methods. First, it is possible to carry out breeding in a planned manner to avoid inbreeding and chaos in order to maintain and produce rabbits of good quality. Second, it is possible to control selection of breeding options and avoid inbreeding, in order to maintain the excellent traits of good varieties and continuously improve the quality of rabbit populations. Third, it is beneficial to maintain the sexual activity of male rabbits and to arrange the number of breedings reasonably, to extend the useful life of rabbits, and to continuously increase the fertility of Saibei rabbits. Fourth, it is conducive to maintaining the health of male rabbits and avoiding the spread of diseases. The specific methods of artificially assisted mating are: 1. Preparation before mating First, conduct a thorough examination before mating with male and female rabbits. All rabbits suffering from warts and other diseases should be treated separately. Determine whether to breed or not. Second, according to the Saibei rabbit selection requirements, the breeding program should be prepared to prevent inbreeding and the use of excellent male rabbits in a planned manner. Third, do a good job of sanitation, thorough disinfection, and prevent the spread of the disease. Fourth, check the estrus of the female rabbit. If it is not in heat, the vulva is pale and dry; if it has been estrus, the vulva mucosa is swollen and moist. However, mating is better when it is old red or black red. Fifth, to strengthen the nutrition of breeding rabbits and female rabbits, we must pay attention to feeding protein feeds and vitamin-rich green feed. Sixth, prepare a variety of registration forms and detail the mating records. Second, the mating program Females with good estrus, suitable for breeding, in the weather sunny morning or evening, after feeding male and female rabbits full of spirit at the time of mating. Before eating the eggs, take out the food dish, drinking fountain, etc. from the rabbit cage, and gently place the female rabbit in the cage of the rabbit. At this point the two sides first use the sense of smell to identify each other's sex, and then the male rabbit chases the female rabbit, and test volley mother rabbit back, or before the full amount of rubbing female rabbit waist breasts, while doing the mating action. If the female rabbit is in heat, the male rabbit inserts the penis into the vagina of the female rabbit. When the male rabbit bends his hips and quickly ejaculates, the male rabbit often screams with the ejaculation action, the hind limb curls, the buttocks slides down, On one side, mating is complete. A few seconds later, the bunnies climbed up and froze again, indicating that the ejaculation had been completed and the female rabbit was returned to its original cage. If the female rabbit is bred in a rabbit cage, the male rabbit chases the female rabbit, while the female rabbit escapes or lies on the ground and clamps the vulva with the tail. At this time, the male rabbit bites the neck hair and ears of the female rabbit with their mouths, or flies on the female rabbit's head, and frequently uses the genitalia to perform flirting flirting with the female rabbit's head. However, the female rabbit still does not accept mating. Remove the female rabbits and allow other male rabbits to mate. If the female rabbits do not receive mating, the female rabbits can be returned to their original cages and reconstituted on the day of arrival. If the female rabbit does not accept the mating and thinks that it is necessary to breed, it may be artificially assisted to mate. That is, with the left hand to grasp the female rabbit ears and collar, the right hand stretched to the abdomen of the female rabbit, raised his buttocks, with the index finger and middle finger grip the tail, exposing the vulva, so that the rabbits can cross mating, can still be mated successfully. It has been observed that this method of artificially assisted mating is also effective, and is also called forced mating. After mating, the male and female rabbits need to rest quietly. At the same time, the date of initial distribution, the type of rabbit used, numbering, etc. will be registered on the mating card of the female rabbit in time. If the female rabbits accept the mating, it indicates that the newborn is not pregnant, and the date of compounding is recorded in the matching card. If the compounding fails, it is often found on the 15th to 20th of the day that the female has a nesting phenomenon. This is a symbol of pseudopregnancy or miscarriage and should be re-mated. Third, pay attention to matters 1, pay attention to the proportion of male and female rabbits It has been observed that a robust adult male rabbit can breed 8-10 female rabbits in the breeding season, and can maintain normal sexual activity and breeding efficiency. 2. Controlling breeding frequency 1 A male rabbit with strong physique and strong sexual desire can mate 1 - 2 times within 1 day and rest 1 day after 2 consecutive days of mating. However, if the female rabbit is estrus concentrated, it may also increase the number of breedings or extend the number of mating days. But not promiscuity, so as not to affect the male rabbit health and semen quality. 3, pay attention to grasp the female estrus law, timely breeding in rabbit breeding practice, the majority of people according to the female estrus rule, sexual desire and the genital area of ​​the red, swollen, moist characteristics of the change, summed up the "pink early, dark purple late , Lao Hong is "the precious experience." In other words, when female rabbits have the most estrus and the visceral mucous membranes are red and red when they are old and red, they can obtain higher fertility rates and farrowing rates. 4. The estrus mating of the mating female rabbits in male rabbit cages should be performed in male rabbit cages. If the male rabbit is placed in a female rabbit cage, male rabbits may easily affect sexual desire due to changes in the environment, and may not even crawl across the female rabbit. If a female rabbit is mated with two male rabbits, the female rabbit must be returned to the original place after the first male rabbit is mated. After a period of time, the female rabbit is sent to the second male rabbit cage after the odor disappears. mating. In case the second male rabbit sniffs out the smell of other male rabbits on the female rabbit, it will not only fail to breed, but may also bite the female rabbit. It is even more difficult to use 2 male rabbits to breed a female rabbit at the same time to prevent male rabbits from biting the frame because they compete for female rabbits and affect the health of rabbits. Under normal circumstances, mating females with good estrus can obtain higher litter size when mated. 5. In case of the following situations, female rabbits that are not more than 3 years old should be bred and should be eliminated as meat rabbits. Diseased female rabbits, especially females suffering from infectious diseases, should wait until they recover from illness and breed litter to prevent the spread of disease, affect the entire rabbit population, and cause greater losses. The blood-related male and female rabbits are not mated to prevent inbreeding and affect the quality of offspring.
The so-called plant-based is the substitution of plant protein for animal protein food grade applications. Plant-based ingredients protein products come from plants such as soy, wheat and peas. That is pea protein powder, soy protein powder, pumpkin protein and so on. The plant protein application category includes protein drinks, dairy substitutes, meat substitutes, protein bars, nutritional supplements, processed meat, poultry and seafood, baking, food and sports nutrition products. Plant protein applications enhance the nutritional and functional properties of products, such as texture, emulsifying properties, solubility, stability and adhesion.
