Cold and warm
Window-mounted glass or nail film, door hanging grass (cotton) curtain, found damaged, timely repairs, to prevent the cold wind invasion of the rabbit body. 15-25°C is the best living environment for Rex rabbits. The minimum indoor temperature for rabbits breeding in winter is not less than 10°C. Attention should also be paid to ventilation and ventilation. Can be used to increase temperature, increase grass mat, cellar insulation, heat in the farrowing box to control the temperature and other methods.
Provide adequate nutrition
Low temperature increases the consumption of calories in rabbits, so winter rabbit diets should generally increase by 20% to 30%, especially to increase some high-energy feed such as corn bran, wheat bran, garcinia or potatoes; feeding times and The quantity should be increased appropriately. After 9 o'clock in the evening, it is advisable to feed the concentrate again to supplement the consumption of cold. Green feed should not be less than 30%. The winter roughage should be matched with reasonableness, and let rabbits eat some cabbages, carrots, malt, and bean sprouts containing vitamins to provide more vitamins. At the same time, enough fodder should be stocked to prevent snow and ice. In the evening when the weather is cold, it is mainly to feed hay, and feed less water to prevent abdominal pain and diarrhea in rex rabbits.
Do a good job of winter
The cold has reduced the activity of female rabbits, and estrus breeding is easily overlooked. In order to make the winter breeding, rabbits should be kept at temperature above 10°C to avoid single feed, and appropriate amounts of feed and vitamin C should be fed to promote normal estrus. In order to promote the estrus of the female rabbits and improve the fertility rate of the mating, artificial aphrodisiac, intramuscular injection of serum gonadotropin 30-50 units, or static injection of 40-60 international units of human chorionic gonadotropin may be used. In general, estrus can be caused 2 to 3 days after injection, and breeding can be performed. The winter breeding time is best performed after the lunar calendar in October. Choose sunny and noon at noon or early morning and evening. In addition, in order for the female rabbits to have more fetuses and have multiple births, mating methods such as “double-matching†and “combination†can be adopted in order to increase the chance of conception.
Raising the survival rate of puppies
In order to improve the survival rate of puppies in winter, plastic film greenhouses, semi-underground rabbit houses or mother rabbits can be used for separate management. It should be pointed out that the rabbit must have colostrum within 4 to 6 hours of birth, and in the event that the individual female rabbits do not breastfeed, they can be forced to breastfeed. For a small number of deciduous or female rabbits that have died and their physique is debilitated, they may be fed cows, goats' milk or other nests. After 20 days of littering, the lactating volume of the female rabbit has reached a peak, and the growth and development of the young rabbit is very fast. Breast milk can not meet the nutritional needs and should be fed before and after the first 18 days of the rabbit. Should be less to make up for, fill 5-6 times a day can be.
