Large-scale rabbit farms need to start from three aspects

Large-scale rabbit farms must be managed in many ways to achieve higher benefits. Nutritional environment control and control of the internal and external environment of the rabbit house are several problems that the rabbit farm must face.

The internal environment control of the rabbit house:

1. Humidity.

Excessive humidity in the rabbit house will affect the metabolism of rabbits and is one of the main causes of enteritis and diarrhea. The suitable humidity range for rabbits is 55%-85%. Inquiry of relevant information shows that the environment with a temperature of 15℃-25℃ and a relative humidity of 50%-80% is most suitable for the growth of young rabbits.

In order to prevent excessive humidity and reduce the source of water in the rabbit house, wash with as little water as possible, use a water-saving bowl drinking fountain, and open windows frequently to reduce the humidity in the house.

2. Temperature

Temperature plays a leading role in various environmental factors. Meat rabbits grow fastest at 15℃-25℃ and have the lowest feed-to-meat ratio; pregnant female rabbits are most suitable for 20℃-25℃.

Rabbits are very sensitive to temperature. Cold in the abdomen can easily lead to diarrheal diseases such as yellow urine disease in young rabbits and gastroenteritis in growing rabbits. When the temperature is higher than 35°C, individual rabbits may have heatstroke, pregnant female rabbits may cause miscarriage, male rabbits' libido, poor semen quality, and even infertility in the fall of rabbits. This is why commodity rabbit prices increase at this time of year.

Therefore, in the cold season, heat and heat preservation measures should be added to the rabbit house; in summer, the roof design of the rabbit house should be changed, and cooling facilities such as spray systems or water curtains should be installed, drinking electrolyte water or 0.1% to 0.2% artificial salt, etc. Lower the temperature in the house and the rabbit body.

3. Light

Proper light can promote the metabolism of rabbits, accelerate the growth of their bones and sterilize them. Maintaining 16 hours of light every day in the nursing female rabbit pen can induce the female rabbit to estrus early. Generally, the female rabbits, young rabbits and back-up rabbit houses keep light for 14-16 hours a day. Male rabbits and fattening rabbits keep light for 8-l0 hours a day, but in summer, direct sunlight should be avoided to the rabbit house.

4. Air

The maximum allowable value of harmful gases in the air in the rabbit house is 3000mg/L for carbon dioxide, 30mg/L for ammonia, and 20mg/L for hydrogen sulfide. Excessive air pollution often occurs in the cold season when doors and windows are closed. The harmful gas in the air exceeds the standard, and rabbits are susceptible to infection or trigger respiratory diseases. Such as bronchitis, pneumonia, etc., can also cause stress syndrome in rabbits, showing decreased appetite, decreased lactation, irritability, or drowsiness. The rabbit houses of the large-scale rabbit farms need to be ventilated in any season to reduce harmful gases in the rabbit houses as much as possible, which is an important measure to improve the production performance of the rabbit herd.

The wind speed is controlled within 20 centimeters per second to control the temperature difference between morning and night and the wind and reduce the chance of catching a cold.

When there is a conflict between heat preservation and ventilation in the severe cold season, peroxide disinfectants can be sprayed into the rabbit house regularly. The released oxygen can oxidize the hydrogen sulfide and ammonia in the air, and play the role of sterilization, odor reduction, dust reduction and air purification.
