Key points of Rex rabbit breeding in autumn

The breeding and management of Rex rabbit in autumn is very important, the breeding quality and breeding of Rex rabbit in autumn are related to the breeding profit before the year ago. the weather is cool in autumn, and the weather is gradually cool, which is a good season for breeding Rex rabbit, but how to raise Rex rabbit in autumn? what do you need to do well?

1. Do a good job of breeding in autumn. It is necessary to strengthen nutrition and carefully raise male rabbits to adapt to the environment and enhance their physique for autumn reproduction. The initial mating age of male rabbits is 7 ~ 8 months old, the female rabbits are more than 6 months old, and the initial mating weight is more than 3.5 kg. Female rabbits reach the peak in late autumn. . The conception rate of mating is 70%-80%, with an average of 5-7 litters per litter.

two。 Do a good job in feed formulation. More green fodder with good palatability should be fed, and roughage with higher protein should be added appropriately. The content of crude fiber in compound feed should be beneficial to maintain the normal physiological function, digestion and absorption of Rex rabbits. It is necessary to make full use of local commonly used, nutritious and low-cost feed resources, especially protein feed, such as alfalfa, locust leaf powder and so on. It should be noted that it is forbidden to feed poisonous green fodder such as dew grass and cotton leaves, to forbid feeding all kinds of moldy feed, and to control carrot leaves and other feeds with high sulfite content.

3. Do a good job of meticulous management. Colds, pneumonia, enteritis and pasteurellosis must be prevented, doors and windows should be closed and outdoor activities should be stopped in case of cooling weather. Open-air rabbit houses should be built in plastic sheds to keep warm. The rabbit house is disinfected with 3% caustic soda and 10% lime water once a week. At the same time, the feces of the rabbit house should be cleaned in time to maintain the environmental hygiene in the house.

4. Do a good job of feed storage. Timely storage of winter feed, such as carrots, locust leaves, sweet potato vines, bean stalks, peanut vines, ruthenica and so on.

5. Do a good job in disease prevention. (1) to vaccinate rabbit plague, Pasteurella multocida and Clostridium welchii vaccine. (2) at the age of one month, one milliliter of each animal was injected subcutaneously or the triple vaccine was used twice a year. In order to prevent the outbreak of coccidiosis, chlorophenyl guanidine and other anti-coccidiosis drugs were added to the formula feed.

Rex rabbit after a long and hot summer suffering, disease resistance has declined, autumn is when the Rex rabbit hair change and female rabbit delivery period, coupled with large changes in day and night temperature, so it is very important to do a good job of epidemic prevention.

First, do a good job in rabbit house disinfection and environmental hygiene. A good sanitary environment can enhance the physique of Rex rabbits. Do a good job of keeping warm and pay attention to ventilation in the morning and evening. Never feed Rex rabbits forage with dew and frost, and insist on regular washing and disinfection of rabbit houses, feed boxes, cages and utensils.

Second, pay close attention to vaccination. Injecting vaccine to Rex rabbits in autumn can make rabbits produce immunity and achieve the purpose of preventing and treating diseases. at present, there are mainly the following kinds of vaccines for Rex rabbits:

1. Rabbit plague vaccine: the effect is good. Each rabbit could produce strong immunity after subcutaneous injection of 1 ml for 5-7 days, and the immune duration was 6 months.

2. Rabbit plague and Pasteurella multocida vaccine: one needle of this combined vaccine can prevent the two diseases and reduce the cost of epidemic prevention. After subcutaneous injection of 1 ml of each rabbit, it was protected from rabbit plague infection for at least 6 months, and 80% of Rex rabbits were protected from Pasteurella multocida infection within 4 months.

3. Inactivated vaccine of Clostridium welchii type A: each rabbit was subcutaneously injected with 2 ml for a protective period of 6 months. This vaccine can prevent and cure Rex rabbit diarrhoea caused by Clostridium welchii A. At present, except for type A Clostridium welchii, there is no other vaccine to prevent and cure Rex rabbit diarrhea in China.

4. The inactivated vaccines of Pasteurella multocida, Potato bacillus and gastric tuberculosis were injected subcutaneously with 1 ml of each Rex rabbit, and the protective period lasted for 4-6 months.

Note: the injection of epidemic (bacterial) vaccine to the Rex rabbit must be carried out according to the bottle label instructions, the injection dose should be sufficient, the injection site should be accurate, and it is required to change a needle for each rabbit injected. Rabbits immunized in spring must be immunized again in autumn.

Third, do a good job in the prevention of rex rabbit coccidiosis. The coccidia infection rate of adult Rex rabbits is low, and that of young Rex rabbits is very high, especially before and after weaning, the mortality rate is very high. When the temperature in the rabbit house is above 10 ℃, it may occur at any time. The commonly used anti-coccidiosis drugs for the prevention and treatment of coccidiosis in Rex rabbits are chlorophenylguanidine, rabbit ball ling, Keqiuling, sulfamethazine and so on. When using anti-coccidial drugs, we should pay attention to master the usage and dosage, so as to avoid accidental conditions such as poisoning.

Note: Rex rabbit immunization program

1. Escherichia coli polyvalent inactivated vaccine

At the age of 20 days, each young rabbit was injected subcutaneously with 1.2 μ g / kg. Milliliters.

2. Noodle plague propolis vaccine, that is, rabbit viral hemorrhagic disease (rabbit plague) fire extinguishing vaccine-- anti-rabbit plague

⑴ pups were injected subcutaneously at the age of 40 days. (first exemption)

⑵ rabbits were injected subcutaneously at the age of 60 days. (as an enhanced exemption)

Every 6 months after ⑶. Subcutaneous injection of 1.5 ml (including female rabbit, breed male rabbit) or subcutaneous injection of 2 ml per rabbit with triple vaccine (rabbit plague, Pap, Wei's).

3. Rabbit pasteurellosis inactivated vaccine against pasteurellosis.

At the age of 40 days, each rabbit was subcutaneously injected with 1 ml or 2 ml of BA-Bo combined vaccine, and then once every 4 months (including breeding male and female rabbits, the dose was the same as above). Note: vaccination should be separated from rabbit plague vaccine during epidemic prevention, usually between 7 and 10 days.

4. Inactivated vaccine against Pleurotus welchii in rabbits.

At the age of 70 days, each rabbit was injected 2 ml subcutaneously, and then every 6 months, 2 ml each time.

5. Staphylococcal inactivated vaccine-prevention of staphylococcal disease

At the age of 80 days, each rabbit was injected subcutaneously with 2 ml, and then once every 6 months (mainly male and female).
