Efficient breeding of rabbit technology must be in place
Rex Rabbit, a scientific name of Rex Rabbit, named after its fur resembling a precious fur beast, is a skin-and-flesh rabbit species native to France, characterized by large size, fast growth, and high hair density. Rex rabbits have short production cycle, high economic value, and economic benefits from artificial breeding. This issue introduces a group of rabbit breeding techniques for farmers' reference.
Culture environment
In the selected rabbit house, the water source with sufficient water and good water quality should be selected where the terrain is high, dry, flat, leeward, low groundwater level, well-drained, and spacious. Stay away from human production, living areas and roads. The rabbithouse should be based on the principle of conservation, heatstroke protection, moisture protection, rain protection, cold protection, pollution prevention, animal protection, epidemic prevention, and convenience of temperature control, humidity control, and light control.
The design of the cage rabbit cage is based on the principle that the rabbit can move freely in the cage. It is twice as long as an adult rabbit and 1.3 times the body length and 1.2 times as long as the cage width.
Breeding management
The breeding male rabbits are 8 to 9 months old, weighing 3.5 to 4 kilograms, and the initial ligand is about 6 pounds. They are 80% lyrical, and it is best to release cage activities 2 times a week to increase resistance and breeding. ability. In principle, breeding 1 day, with 2 days of rest for 1 day, to avoid breeding for 15 consecutive days, so that high spermatozoa, affect the conception rate, the rabbit hair exchange period to be less or not worthy. When breeding, the female rabbit should be brought into the cage of the male rabbit and prohibited from reversing. It is strictly forbidden to put the female rabbit in the male rabbit cage for too long. Generally, the female rabbit is returned to the original cage after one minute. For males that have no ability to breed, have many dead sperm, have low fertility rates, and have severe disease, no species value should be eliminated in time.
The suitable breeding time for female female rabbits is 7-8 months, and can not be earlier than 6 months. The suitable weight is 2.5-3 kg. The initial weight of the female rabbits must reach 5.5 kg and 80% of the lyrics. Empty female rabbits were checked for estrus and mating once a day. Overweight female rabbits were able to return to 80% of the lyrics before they were able to continue breeding. The female rabbit showed a large red color when the female vulva was large and swollen and moist. The female rabbits are generally 10 to 15 days post-natally and 2 days after weaning. When mating, 2 male rabbits are each assigned once, and the interval between them is 5 minutes, and blood is prohibited. After 12 days of mating, the female rabbits touched the fetus and did not continue to inspect for breeding. For the individual to reach the public opinion, the heat is in good condition, and the match is eliminated three times in a timely manner. If the disease is serious, no treatment value should be eliminated in time. Spring is a good season for breeding female rabbits. It is stressful to let the rabbits have more than 2 litters in the spring. The average female pupa period during pregnancy is 30 to 31 days. The female rabbits of 28 days of gestation need to be placed in the farrowing box, and a 1/3 amount of shavings are placed in the box. The shavings must be free of mildew. After exposure and screening, the shavings should be added in time when the shavings are not enough. After giving birth, the female rabbits should be fed with a cup of brown sugar water immediately and fed one tablet of sulfamethoxazole every day for 3 days. After littering, remove dirt and keep the crate dry. The puppies and the female rabbit must be isolated. Generally, the head and the fox have six puppies and no more than eight in the future.
After being born, the rabbit should eat colostrum within 12 hours and then feed it once a day. The difference in maternity should not exceed 2 days and the same size should be put together. After 2 hours of adjustment, the baby should be fed again. Check the baby's feeding status every day. If you are not full, you need to feed it at night or feed it the next day. After being fed with milk, the young rabbits should be separated from the female rabbits and carefully inspected to ensure that they can all eat enough milk. After feeding, all the puppies are placed in the central box of the breeding box for warmth, covered with litter, and covered with old clothes to keep warm. . For forced feeding of female rabbits whose milk is not fed, cover for 2 to 3 minutes with empty feeding boxes. Female rabbits without milk can feed 15 to 20 grains of cooked soybeans daily. Keep the box dry and warm, the temperature of the pups is higher than the temperature of the hand. Especially for 10-day-old rabbits, the temperature is particularly important. Check the internal conditions of the crate every day and find that dirt and rabbit dung are cleared out in time. Every time you change the litter should not be completely replaced, step by step to prevent the female rabbit does not adapt to the smell and puppies do not meet, refused to breastfeed.
The rabbits should be fed in time to the age of 16 days in order to increase the growth rate and survival rate of the young rabbits. It is advisable to use green feeds within 2 days of feeding. The pups are generally weaned at about 35 days of age, and the weight must be 1.2 pounds.
Commercial rabbit fattening
In the early growth stage of rabbits, the hair follicles are severely differentiated. If nutrition is satisfied, the hair density can be greatly increased. After 3 months of age, the hair follicles are differentiated slowly. After 5 months of age, the hair follicle differentiation is almost complete. At this time, providing high nutrition will not help. Therefore, early culture of commercial rabbits is crucial.
The first is to strengthen environmental control. The temperature should be kept between 15°C and 25°C. The temperature at the late stage of fattening can be properly reduced to improve the quality of the fur; the humidity is controlled at about 60; 10 to 14 fattening rabbits are reared per square meter of cage area; there is a certain amount of light, but No need for strong light; strengthen ventilation, keep the air fresh in the rabbit house; keep cages clean, sanitary, and healthy.
The second is to improve feeding techniques. It is advisable to provide pelleted feeds that are fed freely to increase the rate of weight gain. Unconditional wet mix can be taken with powder, to feed in the hands into a group, the fingers are sewn with water, but not dripping, open the cracks can be, to take regular feeding, less feed Tim Tim; in the green feed supply season, Take the green feed as the main daytime and supplement the feed once at night to save feed costs.
The third is to use soybean powder 6 (fried hot), anise powder 7, ferrous sulfate 8, licorice powder 9, dried ginger powder 20, cinnamon powder 50, fully mixed in the mixture, and add appropriate amount of water and mix well, each The rabbits were fed 3 grams a day and fed one more time every other day. After 15 days, the weight gain was obvious. On average, 35 to 50 grams per day could be gained.
The fourth is to provide sufficient clean drinking water for their free drinking.
Feeding method
Rex rabbits are mainly fed with green and rough feeds. Generally, green materials account for 60 to 70 rations, and coarse and fine materials account for 30 to 40. Feeding should be diversified, drinking water should be fresh and clean, and changing feed should be gradually carried out. Rex rabbits are sweet and vegetarian, and don't like powdery, smelly feeds. When feeding powder, it is necessary to mix with water and then feed, otherwise it is easy to be sucked into the air intake and cause respiratory diseases.
When feeding, it is necessary to be regular, quantitative, but also flexible, you can take "seven see feeding method": a look at weight, body weight and more to feed more; two to see the sensation, good lyrical feeding less; three to see the feces, If the feces are dry and hard, increase the green feed and increase the drinking water. Otherwise, on the contrary, if necessary, feed the medicine. When the hunger is full, the amount of feeding may be appropriately increased when hunger is full. When the age is observed, the frequency of adult rabbit feeding is less, generally 3 times a day, middle-aged rabbits 4 to 5 times, just weaned puppies 5 to 6 times a day, and asked to feed the quality of good digestible feed; six to see the number of litters, breast-feeding rabbits, puppies have begun to eat Materials, more feed, more feed; look at the season, hot summer, feed early in the morning to feed, fine and less at noon, to feed at night. Cold in winter, you need to feed in the morning, eat well at noon, eat at night, add night grass at night, and pay attention to add juicy feed. More hay is fed during the rainy season, and more green material is needed during the dry season.
When feeding, a certain percentage of concentrate may be added according to the nutritional standards, but do not feed the concentrate on a partial basis. Excess concentrates are easily decomposed and fermented into a large amount of organic acids in the cecum, destroying the normal weak alkaline environment of the microorganisms and causing an imbalance in the ecological balance of the flora. Therefore, fiber roughage is indispensable.
Feeding rabbits with pelleted feeds works well, but pelleted feeds are not yet widely available in rural areas. Some farmers use whole grain instead of pellets to feed them. They should crush or grind the grains and mix them with the roughage in proportion.
Disease prevention and control
The immunized pups were born 30 to 35 days of age with subcutaneous injections of Trichophyton pneumoniae - Pasteurella - Clostridium perfringens triple vaccine; pups were treated with prophylactic Escherichia coli in the diet after weaning; at the age of 60 days a second injection was required. Rabbit quail single vaccine.
Mastitis in female rabbits Mice were intramuscularly injected with 2 ml of rhubarb doxorubicin for 2 to 3 days postpartum, or oral administration of sulfamethoxazole 0.5 g daily, together with equal doses of baking soda, for 3 days.
The yellow urine of pups was born 3 to 5 days after pups were born. The drops of gentamicin or rhubarb were given 3 drops each time for 2 to 3 days.
Coccidiosis was used for drug prevention at the age of 30 days after birth in rabbits. Three or more coccidiosis drugs were used in combination with antibiotics. Each treatment course lasted for 7 days, followed by 10 days of drug withdrawal before the next course of treatment was continued for 4 consecutive courses. Common anticoccidial drugs include diclazuril, chlorpheniramine, and monensin.
Rickets generally carries out two full-group preventions in the spring and autumn season. Commonly used drugs include ivermectin and levamisole hydrochloride. The diseased rabbits were immediately isolated and treated with 0.1 to 0.2 ml of ivermectin administered subcutaneously or washed with trichlorfon against white spirit and administered once every 4 days.
E. coli disease can occur throughout the year, mainly affecting the 20-day-old and pre- and post-weaning puppies and young rabbits. The incidence of common group rabbits is higher than cage-raised rabbits. With Ngino injection, 0.5 to 1 ml per kilogram of body weight, 2 times a day, intramuscular injection, once every 3 days; follow the instructions to feed it with Asthma, kill for 5 days. Some astringent antidiarrheal Chinese herbal medicine can be used for treatment. Every 500 birds use 45 grams of tulip, 45 grams of silver flower, 45 grams of forsythia, 50 grams of rhubarb, 20 grams of gardenia, 35 grams of gardenia, 20 grams of white peony root and 20 grams of radix astragalus. Cork 20 grams, Shuijianbi, used for 3 days.
