Maintaining the temperature has proved that if the temperature of the rabbit house is lower than 5°C, the estrus of the female rabbit will be stopped and the mating of the male rabbit will be reduced; if the temperature of the farrowing box is lower than 15°C, the pups will be more difficult to survive.
The following methods can be used to warm up:
1, buckle shed warming. The rabbit house was built on the leeward sunny side, plastic cloth was put on in winter, and grass cover was kept warm in the evening. This method can reach temperatures above 25°C during the day and 15°C or so at night, which is suitable for rabbit farms with a certain scale. Pay attention to the ventilation during the day when the temperature is high.
2, cellar insulation. That is, the gestating female rabbit is placed in a cellar, so that it breeds itself in a cellar, and after the rabbit is full, the female rabbit is brought 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, in the litter box with electric heating. The most common method is to heat the bulb above the litter 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.
Supply adequate nutrition Winter crude feed should be reasonable, let rabbits eat some carrots, malt, bean sprouts and other vitamins. 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.
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, generally after the injection 2 -3 days can cause estrus and can be bred. It is advisable to adopt repeat breeding. The time must be chosen at sunny and windless noon.
