How does the hare keep warm and keep cold in spring?

Hare is a new breed raised in recent years, its meat quality is more delicious than rabbits, disease resistance, vitality is stronger, the market price is also higher than rabbits, so many small and medium-sized investors have developed special hare breeding. However, at present, many breeders lack experience in the heat preservation and cold protection of rabbits in spring, which leads to the decline of their production performance and economic benefits. This paper introduces the relevant measures of cold protection and heat preservation in spring from the external and internal aspects of the rabbit house.

Measures against cold and heat preservation on the outside of rabbit house

1. The thickened roof can be covered with straw 5cm thick, or a layer of thermal insulation foam can be installed below, so that the cold air can not blow into the rabbit house, and the hot air is not easy to escape from the roof.

2. The wall of the rabbit house is covered with boards, straw curtains, plastic films, straw bundles or straw bags to seal up the places around the rabbit house that are blown or leaked by the wind, so as to prevent the invasion of cold wind; the accumulation of appropriate straw outside the north wall of the rabbit house also has the function of keeping warm from the wind. The outer wall of the rabbit house is usually wrapped with plastic film and fixed with nails and wooden slats, and the thermal insulation materials can be recycled.

3. Thickening doors and windows, rabbit house wall doors and windows are made into double layers or by the way of glass and film, the heat preservation effect is better.

4. do a good job of heat preservation and ventilation in cold weather, open doors and windows after 10:00 every morning for ventilation, if stocking, put the hare on the playground, and close the doors and windows according to the temperature after 4 p.m., which is an important work of heat preservation. During ventilation, as moist air and harmful exhaust gas are more deposited in the lower layer of the space, opening the floor window is more conducive to the discharge of moisture from the house and keep the environment dry.

Measures of cold protection and heat preservation in rabbit house

1. The mother rabbit breeding house should set up a greenhouse when the temperature is below 18 ℃, in order to maintain the normal living environment of the baby rabbit, a warm room is needed. The breeding rabbit house can be heated properly with a heater or electric furnace, or a fire can be used to heat the breeding rabbit house. In order to prevent carbon dioxide poisoning, it is necessary to use a pipe to discharge the exhaust gas.

2. Young rabbits and young rabbits should be kept warm reasonably.

① increased the feeding density of rabbits in the house. The feeding density of the rabbit cage in the cold season is 30%-50% higher than that in summer and autumn. Let the rabbit sleep next to each other, which can increase the temperature of the rabbit cage.

Flexible arrangements for ②. According to the characteristics that young rabbits need higher temperature and stronger ability to resist cold, younger young rabbits can be arranged in the upper layer with higher room temperature, and older rabbits can be arranged in the lower layer at lower room temperature.

3. The air conditioning in the breeding rabbit house is equipped with air conditioning in the breeding rabbit house, so that the rabbits to be bred can live in the rabbit house with a temperature of 18-28 ℃. At this temperature, the pregnancy rate of female rabbits is high, and it is easy to mate successfully.

4. using the biogas from the biogas digester in the rabbit farm, the heating system is installed with biogas to heat the hot water blast furnace and heated with hot water pipes (similar to the heating system of northern buildings), so that the rabbits can only lie on the floor. The temperature in the house should be kept above 18 ℃, and the temperature should be adjusted according to the physique of the young, weak, sick and disabled rabbits.

5. Lay dry bedding material in the cage, and timely ventilate the rabbit to set up wooden boards and dry straw in the lying place to reduce the heat loss of the rabbit body. When the weather is sunny at noon, you can take advantage of the high temperature period to put the rabbit to the playground to bask in the sun, which is conducive to speeding up the blood circulation of the rabbit body and strengthening its physique; open doors and windows and ground windows for moderate ventilation to promote air circulation in the house, and at the same time, the moisture and harmful gases in the house can be eliminated.

6. regular removal of feces and urine due to more feces and urine and high humidity in the rabbit house, the room is more humid and colder, and there are more harmful gases, which is easy to cause respiratory diseases of rabbits. Therefore, timely removal of feces and urine can greatly reduce the humidity and increase the temperature in the house. If the rabbits are trained to defecate outside the house and eat and live in the house, the humidity of the rabbit house will be reduced and the air will be better. To the rabbit house that sets up the dung and urine ditch on the floor, after cleaning the floor, the entrance of the interior and exterior of the house must be blocked with a plank to prevent cold wind from invading.

7. Adopt dry dung cleaning technology in overcast, rainy and cold weather in winter and spring. Rabbit dung should be collected by cleaning and eliminating, so as to reduce the water used for washing in the house as much as possible, so as to reduce the heat loss and humidity in the house.

8. Turn on the hot air facilities electric blast stove and coal heating hot air stove, which are mostly used to deliver warm fresh air to the mother rabbit litter house and the rabbit breeding house. The air in the rabbit house is warm and dry in spring, the air temperature in the litter room of the mother rabbit is 20: 23 ℃, the survival rate of the young rabbit is increased, and the disease is reduced and the growth is good when the temperature of the rabbit breeding house is 20: 24 ℃.

9. Lack of water in rabbits fed with warm water often leads to indigestion, loss of appetite, metabolic disorder, decline in body fat and so on, so rabbits in captivity must be provided with enough warm water of about 20 ℃ in cold season. The hot water pipe of the blast furnace heated by biogas can be used to provide clean hot water for the rabbit farm (only drinking water, mixing feed and cleaning water for rabbits). At the same time, pay attention to the leakage of water supply system and automatic drinking fountain to prevent excessive humidity in the house caused by water leakage.

10. Changing the wet disinfection in the house to flame disinfection will increase the humidity in the house, which is not conducive to the heat preservation and dehumidification of the rabbit farm in spring. Using LPG spray gun to disinfect the objects that are not afraid of fire in the rabbit farm can not only achieve the purpose of disinfection, but also improve the ambient temperature in the house, killing two birds with one stone. Flame disinfection is especially suitable for disinfection of female rabbit birth house and rabbit breeding house, as well as rabbit hair removal and environmental disinfection of rabbit house and rabbit cage under the environment of changing rabbit hair.
