Insulation It has been proved that once the rabbithouse temperature is lower than 5°C, the female rabbit stops estrus and the male rabbit is reduced in libido. Once the temperature of the childbirth box is lower than 15°C, the rabbit is difficult to survive. The following methods can be used for heating and heat preservation in production. Booth warming The rabbit house is built on the leeward sunny side. In the winter, a plastic sheet is attached to the outer wall of the rabbit house, and a layer of straw is covered in the evening. Using this method, the temperature of the rabbit house can reach 25° C. during the day and 15° C. at night. It should be noted that when the temperature is high during the day, ventilation and ventilation should be performed in time to ensure the fresh air in the rabbit house. Cellar insulation That is, the gestating female rabbit is placed in a cellar and allowed to breed by opening a hole. After the rabbit is full, the female rabbit is brought out. This method saves money and the survival rate of rabbits is high, which is very suitable for raising rural garden farmers who have less rex rabbits. Electric heating The most common method is to suspend light bulb heating above the birthbox. A 25-watt incandescent light bulb is generally installed in a production box to keep the temperature inside the box at about 20°C. Note that the bulb ion rabbit needs a certain distance to avoid burning rabbits. Provide adequate nutrition The winter roughage should be reasonable, and you should feed more vitamin-rich carrots, malt, and bean sprouts. In the evening when the weather is cold, you should use hay as the main feed, and feed less water to prevent abdominal pain and diarrhea in rabbits. Reasonable breeding In order to promote the estrus of female rabbits and increase their mating rate and conception rate, artificial aphrodisiacs can be performed, such as intramuscular injection of pregnant sera (30 international units - 50 IU), or intravenous injection of human chorionic gonadotropin (40 IU - 60 international units) etc. After the female rabbit has been injected with the hormone, it is estrus 2 days to 3 days, and breeding can be performed at this time. In order to increase the fertility rate of the female rabbit, it is best to repeat the breeding, and the time should be selected at sunny and windless noon.
