(1) Roof irrigation
The temperature in the rabbit house comes from solar radiation, and the roof is the main heating part. Reducing heat transfer at the top of rabbit house is an effective measure to reduce the house temperature.
If the flat-topped rabbit house is made of cement or prefabricated board, on the basis of seepage prevention, the periphery of the roof can be raised to form a trough at the top, and water can be poured into the trough every day or at intervals to maintain a certain amount of water for a long time, which has a good cooling effect. If the building quality of the rabbit house is good, if such measures are taken, the rabbit house can be kept below 30℃ in summer, so that the mother rabbit can continue to breed in summer.
(2) Spray water on the roof
No matter what kind of rabbit house, it is good to spray water on the roof at noon when the sun is strong and reduce the temperature through evaporation of water. In some simple rabbit sheds in the United States, a water pipe is connected to the top ridge of the rabbit shed in summer, and many small holes are drilled evenly on both sides of the water pipe, so that it can automatically spray water on both sides, which is a very effective way to cool down. When the weather is particularly hot, you can cooperate with the air in the house and spray water on the ground to quickly relieve the thermal stress.
(3) Roof greening
If it is a flat-topped rabbit house, it has a certain tolerance. You can cover the top of the rabbit house with thick soil and plant grass (such as lawn), vegetables or flowers on it, which has a good effect on cooling the rabbit house.
(4) Planting in front of and behind the house
Plant tall trees (such as phoenix tree with a large crown), loofah, plum bean, grape, Parthenocissus tricuspidata and other vines at a certain distance in front of and behind the rabbit house to block the sunlight and reduce the direct heating of the rabbit house.
(5) Paint the wall
Different colors have different absorptivity and reflectivity to light. Black has the highest light absorption rate, while white has a strong light reflectivity. It can be painted white at the top, south and west walls of the rabbit house where the sun shines directly, reducing the heat of the rabbit house and enhancing the light reflection.
(6) laying a reflective film
In recent years, in order to improve the coloring degree of fruits (mainly apples), the method of laying reflective films on the ground has achieved good results. According to its principle, a reflective film can be laid on the top of the rabbit house. According to the author's experiment, the greenhouse temperature can be reduced by about 2℃.
(7) Stretching refraction net
Pulling a refraction net at the top of the rabbit house and outside the window has been proved to be an effective cooling method. Its refractive index can reach 70% and its service life can reach 4 ~ 5 years.
(8) Build a arbor
For outdoor shelf rabbit huts, in order to reduce the cost, we can use firewood, branches, grass curtains and so on to build a arbor, which can play the role of refraction, shading and cooling. This is a simple and easy cooling measure.
(9) Strengthen ventilation
Open doors and windows, install electric fans, etc. Strengthening the air flow in the rabbit house can reduce the stress degree of high temperature on rabbits. The combination of wet curtain and forced ventilation is better in conditional rabbit farms.
When the above measures are used together, there will be a cumulative effect.
