What are the key points of Rex Rabbit (Rex Rabbit) winter management?

Rex rabbit, also known as Rex rabbit, is a kind of rabbit with high fur economic value, which has a cool feeling with hands. Rex rabbit is more important in management, especially in winter, when the temperature is relatively low, it brings some difficulty to the management. So what are the key points of Rex rabbit management in winter?

First, do a good job in rabbit house hygiene and overwintering deworming

In winter, special attention should be paid to the environmental hygiene of the rabbit house, and the rabbit house should be disinfected regularly. Disinfection should be rotated with more than two kinds of disinfectants to prevent drug resistance; the rabbit house should be cleaned frequently, remove feces and dirt every day, prevent moisture with quicklime, keep the house clean and dry bath, to prevent the accumulation of feces and urine, reduce the production of irritating gases such as ammonia and hydrogen sulfide, and prevent respiratory diseases such as rhinitis and pneumonia. In addition, disinfection should be taken seriously and the rabbit house should be kept dry. In order to keep warm, the tightness of the rabbit house increases in winter, but poor ventilation, ammonia, hydrogen sulfide, sulfur dioxide and other harmful gases increase, which is easy to induce Rex rabbits suffering from eye conjunctivitis, rhinitis and other diseases, therefore, to install ventilation devices, and strengthen automatic ventilation, you can open doors and windows from 11:00 to 2 p.m. Every day, use the natural wind to breathe, and grasp the smell at any time. In order to make the Rex rabbits survive the winter safely and strengthen their physique, ivermectin or avermectin and Quechongjing were used before overwintering (late autumn). All adult rabbits and young rabbits were treated with parasite in vivo and in vitro to prevent the invasion and harm of parasitic diseases.

Second, do a good job of cold protection and heat preservation

Rex rabbits are afraid of heat and are more resistant to cold, but there is a certain limit to their cold tolerance. If the temperature falls below 5 ℃, they will feel uncomfortable. The naked and colorless rabbits are especially afraid of freezing. They will freeze stiff under 10 ℃ and freeze to death under 5 ℃. Therefore, in winter to do a good job of cold protection and warmth is very important for raising Rex rabbits.

1. Although the winter temperature is low, except for newborn rabbits, the rabbit house temperature is not required to be very warm, but it is required that the temperature should be relatively stable and not hot and cold. In winter, the best temperature for Rex rabbit growth should be 15 ℃ ~ 25 ℃, 2. Increase feeding density, rely on rabbit body heat to increase temperature; young rabbits should not be raised in a single cage, young rabbits must be moved to a warm room.

3. When raising rabbits indoors, close the doors and windows to prevent the attack of thieves; when raising rabbits outdoors, grass curtains should be hung on the cage door to prevent cold wind from invading. Try to keep the ventilation to a minimum in order to preserve the heat generated by the rabbit.

4. Sufficient and reasonable light is a necessary condition for the normal growth and development of Rex rabbits. Artificial light and natural light are usually used. Transparent plastic film can be covered before and after the rabbit house to make full use of solar light, increase the amount of indoor lighting as much as possible, and achieve artificial warming. The Rex rabbit can obtain good production performance under the condition of 12 ~ 16 hours of light every day. Conditions can also be installed in the house heating equipment, such as heating, electric heater, stove and so on.

Third, do a good job of breeding in winter

While doing a good job of cold prevention and heat preservation, it is very important to arrange winter reproduction and winter breeding, which has the advantages of high survival rate and high rate of birth. The young rabbit has the advantages of fast growth, large size, strong physique and high wool yield, so it is the most suitable for breeding. As long as we do a good job of preventing cold and keeping warm, good results can still be obtained in winter breeding, especially the survival rate of young rabbits is high and there are few diseases. In the actual production, as long as the heat preservation of the litter box is done well, the bedding grass is dry, soft, strong heat preservation, good hygroscopicity and keeping the temperature above 5 ℃, a better effect of winter propagation can be obtained.

With the decrease of air temperature in winter, inactive pathogenic microorganisms, less infectious pathogenic microorganisms, less rabbit disease and high survival rate of young rabbits, it is possible to breed and raise Rex rabbits in winter as long as they create a constant temperature environment for Rex rabbits. Although the estrus of female rabbits is not obvious, they can estrus and ovulate normally. Therefore, we should seize the opportunity to breed female rabbits at noon when the weather is sunny, windless and sunny. Breeding should grasp the agricultural proverb: pink early, black purple late, bright red at the right time. In order to improve the conception rate, repeated breeding or double breeding can be used. In addition, 12 days after mating, the female rabbit should touch the fetus in time. The method of touching the foetus is to hold the ear and collar skin of the female rabbit with the left hand, fix the female rabbit on the flat ground or table, make the rabbit head face the chest of the foetus toucher, put the right hand under the belly of the female rabbit, and gently touch the embryo from back to front. The embryo is spherical and elastic, and the dung ball is hard spherical and inelastic. The empty pregnant female rabbits that are not pregnant should be replenished in time. In addition, the lactation period of winter breeding young rabbits should be long, generally do not engage in blood matching, it is appropriate to reproduce 1 ~ 2 births.
