The temperature rises in spring, the climate is suitable, and forage is abundant, which is the season of rabbit breeding. We must grasp this favorable opportunity to expand the rabbit population and increase economies of scale. Choose a good breed of rabbit saying: "The female rabbit is good, a good group; the male rabbit is good, a good tune." So choose a healthy, well-balanced, strong sexual desire, strong mating, body appearance meet the requirements of the species, hereditary stability, Kind of male rabbit with strong disease resistance. Female rabbits require good genital development, more than 4 pairs of nipples, normal estrus, high litter size, and high lactation levels. The breeding of male rabbits and empty-heart female rabbits require comprehensive dietary nutrition, diversified feed, reasonable collocation, good quality, good palatability, and easy digestion, so that the rabbits can maintain the medium sensation of not being fat or not, so as to improve the breeding ability. Recommended empty female feed formula: wheat bran 30%, corn 10.8%, soybean cake 18%, grass powder 40%, bone meal 1%, salt 0.2%. The male rabbit feed formula: 53.5% corn, 25% bran, 20% soybean cake, 1% bone meal, 0.5% salt, additional 0.02% multi-dimensional pigment. Feeding should be regular, quantitative, and fixed times. Green grass generally feed 4 times, fine material 80-100 grams, green material 1000 grams. Implementing first-time materials to increase feed intake, and paying attention to diets such as fish meal, silkworm cocoons, carrots, malt, and shellfish. Strengthen the rabbit movement, appropriate to add light. Keep them alone to prevent fighting each other. Timely breeding In order to improve the fertility rate of the mating, the maternal rabbit should be selected for breeding during the estrus period. According to the color of the female rabbit's vaccination, the timing of breeding is determined, namely, "Pink is early, dark red is late, and fiery red breeding is at the same time." A female rabbit can be bred with two male rabbits in estrus, or can be bred twice with the same male rabbit for 8 hours. Mating time is best arranged at 3-5 in the morning. After mating, the female rabbit is lifted up and tapped twice by hand to prevent the outflow of semen. This will not only increase the rate of conception, but also allow the female rabbits to be born during the day to facilitate care and increase the survival rate of the pups. Artificial aphrodisiac has good body condition, normal genitals, females that can normally mate with estrus in the past, and does not show estrus in this estrus breeding period. Artificial aphrodisiac breeding can be used. The commonly used aphrodisiac methods are: (1) Drug aphrodisiac: 50-100 units of chorionic gonadotropin are injected into the medial muscle of the female rabbit's fetus, and 4-6 hours after injection; (2) Provocative aphrodisiac: the female rabbit is placed in a male rabbit cage Inside, let the male rabbit chase after crawling, stimulate the female estrus, in the morning aphrodisiac breeding; (3) breath aphrodisiac: the female rabbit into the male rabbit cage, any male rabbit chasing crawling, after a period of time put the male rabbit Let the female rabbit spend the night in the male rabbit cage and fully accept the male rabbit's breath. On the second day, the female rabbit will be in heat and can be bred. After raising female rabbits during maternity and lactation, 7 days after mating, the female rabbits are placed in a male rabbit cage. If the female rabbit refuses the male rabbits to crawl, and if the female rabbits are crouching and squealing, they are pregnant. Unfertilized need to be reconfigured. Female rabbits should be fed full price feeds during pregnancy. After 2-4 days of delivery, they should increase the daily amount (1 to 1.5 times normal) and feed more green and blue juicy feed and bean cakes, wheat bran, bean dregs, fish meal, and bone meal. , minerals, etc., to increase their milk production and prevent the female rabbit from eating pups. Female rabbits must be carefully managed during the second and third trimesters of pregnancy. They cannot be caught or scared to prevent miscarriage. To feed alone, avoid feeding moldy, frozen feed. Keep the rabbit house quiet, dry and hygienic, and prevent animals such as cats, dogs and rats from invading. Carefully raise the young rabbits and quickly clean their mouth and nose mucus with a clean, soft towel and put them in the litter box for protection against cold and warmth. Timely to allow the pups to eat enough colostrum to enhance the body's immune system. Puppy rabbits can be trained to eat at 15 days of age, and they can feed easily digestible, nutrient-rich feeds such as young grasses, leaves, etc., so that they can eat small meals. The compound feed can be fed at 35 days and weaned at the appropriate time. The following formulas are recommended: corn 57%, wheat bran 23%, bean cake 4%, vegetable cake 4%, cocoon 10%, bone meal 1.5%, salt 0.5%. Keep your environment quiet and do not be scared. It is better to have a dark interior in the rabbit house. If the female rabbit has too much litter in a litter, the foster-type artificial nursing can be used to ensure timely weaning and increase the number of fetuses in the whole year. Doing a good job of health and epidemic prevention A variety of pathogenic microorganisms have begun to multiply in the spring, which is the peak season for various diseases of rabbits. It is imperative to do a good job of sanitation and epidemic prevention. This is an important guarantee for improving the reproduction rate of rabbits. Rabbits, rabbit cages and utensils should be carefully cleaned to keep them dry and clean. Rabbits should be regularly sterilized with 20% sodium hydroxide solution, and 0.1%—0.5% potassium permanganate be used as drinking water or utensils for sterilization. Use 2%—3. % Sushui water is used to disinfect the ground or utensils; it is forbidden to feed mildew, deterioration, silt, dew and poisonous and harmful feed; regular addition or mixing of chlorophenylhydrazine, trilobular coccidiosis powder, nitrofurazone, and salinia Such as preventing the occurrence of coccidiosis; adding appropriate amount of osmanthus leaves, locust leaves, bitter leeks, plantain, Houttuynia, dandelion, wild chrysanthemum, etc. in the lactating female rabbit diet, which can prevent mastitis in female rabbits. Occurrence, but also can effectively improve the survival rate of pups; all rabbits imported from the field should be isolated after 3 weeks of observation, confirmed that no disease before gregarious, rabbits and puppies adhere to the spring inoculation of rabbit Pasteurella multocida double vaccine Immunity; Observe the rabbit group at any time. Once the diseased rabbit is found, isolate it timely and strictly disinfect it.
Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
