Breeding techniques of Rex Rabbit in Winter

Protect against cold and keep warm

Window glass or nail film, door hanging grass (cotton) curtain, found damaged, timely repair, to prevent cold wind from invading the rabbit. 15-25 ℃ is the best living environment for Rex rabbits. The lowest indoor temperature for breeding Rex rabbits in winter is not less than 10 ℃, and attention should be paid to ventilation. The temperature can be controlled by means of heating up the shed, adding bedding grass, cellar heat preservation, electric energy heating in the litter box and so on.

Provide adequate nutrition

Low temperature increases the calorie consumption of rabbits, so the dietary supply of rabbits in winter should generally be increased by 20% Mel 30%, especially by adding some high-energy feed such as corncob, wheat bran, cabbage or potato, etc.; the feeding times and quantity should be increased appropriately, and one more time of concentrate feed should be fed after 9 pm to supplement the consumption of keeping out the cold. Green feed should not be less than 30%. Winter roughage to be reasonable, let rabbits eat more vitamin cabbage, carrots, malt, bean sprouts and so on, in order to provide more vitamins. At the same time, enough forage should be stored to prevent snow and freezing. In the cold evening, we should mainly feed hay and feed less moisture to prevent abdominal pain and diarrhea in Rex rabbits.

Do a good job in winter reproduction

Severe cold significantly reduced the activity of female rabbits, and estrus mating was easy to be ignored. In order to breed well in winter, breeding rabbits should try to keep the temperature above 10 ℃, avoid single feed, and feed germination feed and vitamin C properly to promote normal oestrus of female rabbits. In order to promote estrus and improve the conception rate of female rabbits, artificial estrus can be induced by intramuscular injection of pregnant horse serum gonadotropin 30Mel 50 units, or intravenous injection of chorionic gonadotropin 40Mel 60 international units. Generally, estrus can be caused 3 days after injection and mating can be carried out. Winter mating time is best after October of the lunar calendar, choose sunny and windless noon or morning or evening. In addition, in order to make female rabbits conceive more and produce more babies, mating methods such as "double mating" and "compound mating" can be adopted to increase the chances of conception.

Improve the survival rate of young rabbits

In order to improve the survival rate of young rabbits in winter, plastic film greenhouse, semi-underground rabbit house or female rabbit can be used to manage separately. It should be pointed out that baby rabbits must eat colostrum within 6 hours after birth. If individual female rabbits are not breastfeeding, compulsory breastfeeding can be carried out. For a small number of lack of milk or the death of female rabbits or the physical weakness of young rabbits, they can be fed to cattle, sheep's milk or another nest for foster care. The milk yield of female rabbits reached the peak 20 days after giving birth, while the growth and development of young rabbits was so fast that breast milk could not meet the nutritional needs, so feeding should be started around 18 days after birth. It is advisable to give less and more supplements, and you can replenish it 5 times a day and 6 times a day.
