Rabbit's winter breeding technique

First, maintain the temperature Practice has proved that if the rabbithouse temperature is lower than 5 °C will make the female estrus to stop, the male rabbit's mating desire to reduce; if the temperature of the farrowing box is lower than 15 °C, puppies are more difficult to survive. The following methods can be used to increase the temperature: 1. The temperature of the shed is raised: the rabbit house is built on the leeward sunny side, the plastic sheeting is put on in winter, and the straw mulch is kept warm in the evening. This method can reach a temperature of 25°C or more during the day and 15°C at night. Around, suitable for a certain size of rabbit farm. Pay attention to the ventilation during the day when the temperature is high. 2, cellar insulation: that is, the pregnant female rabbit in the cellar, let it in the cellar hole breeding, such as the full moon after the baby, the female rabbit out. This method saves money and has a high survival rate. It is suitable for use by rural garden farmers who have few rex ​​rabbits. 3. Electric heating in the farrowing box: The most common method is to heat the bulb above the farrowing box. Usually, a 25-watt incandescent bulb is installed in each farrowing box to keep the temperature inside the box at about 20°C. Note that the bulb must be a certain distance away from the pups, so it is better not to feel hot on the pups. Second, to provide adequate nutrition Winter rough feed to be reasonable, let the rabbit eat some carrots with vitamins, malt, bean sprouts and so on. 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 rabbits. Third, reasonable breeding In order to promote the female estrus, and improve the fertility rate of breeding, artificial aphrodisiac, intramuscular injection of serum gonadotropin 30 ~ 50 units, or intravenous injection of human chorionic gonadotropin 40 ~ 60 international units. In general, estrus can be caused 2 to 3 days after injection, and breeding can be performed. It is advisable to adopt repeat breeding. The time must be chosen at sunny and windless noon.
