Do cold insulation
Although the winter temperature is low, but in addition to neonatal rabbits, the rabbithouse temperature does not require warm, but it is required that the temperature should be relatively stable and can not be hot and cold. In winter, the optimum temperature for the growth of Rex rabbits should be 15~25°C. Over-cooling and overheating have a great influence on their physiological functions, generally not lower than 10°C and higher than 29°C.
Increasing the breeding density depends on the cooling of the rabbit body; the young rabbits should not be raised in single cages, and the puppies must be moved into a warm room.
Indoors rabbits should be closed doors and windows, to prevent the thief wind invasion; outdoor rabbits, the cage door should be hung a good straw curtain to prevent cold wind intrusion. Try to minimize the amount of ventilation in order to save the heat generated by the rabbit body.
Full and reasonable illumination is a necessary condition for the normal growth and development of rabbits, and artificial light and natural light are generally used. The transparent plastic film can be covered before and after the rabbit house to make full use of the sunlight, maximize the amount of indoor lighting, and artificially increase the temperature. Rex rabbits can obtain good production performance with 12 to 16 hours of light per day. Conditions can also be installed in the heating equipment, such as heating, electric heaters, stoves and so on.
Strengthen feeding management
Increase feed supply. Due to the low temperature in winter, rabbits consume more calories. Therefore, the daily feeding amount of large and small rabbits should be 20%~30% higher than usual, and the proportion of high-energy feeds should be appropriately increased. In addition, due to lack of green feed in winter, prone to vitamin deficiency, should try to feed some leaves, carrots, barley malt and tuber-like feed, etc., to supplement the deficiency of vitamins.
The powder should be added with a small amount of bean dregs or bran, warmed with warm water and then fed, and should be fed less frequently to prevent the leftover material from eating after being frozen.
When using coarse powder feed, wet mix should be reasonable. Coarse powder should be mixed and stirred uniformly. Before feeding, mix 1:1 with warm water and wet. Generally, grasp the hand wet material without dropping the water between the fingers. It is used nowadays. It is not suitable to mix more to keep the feed. Freshness, palatability.
Do a good job in rabbit house hygiene and wintering pests
In winter, special attention should be paid to improving the environmental hygiene of rabbit houses and regularly disinfecting the rabbit houses. Disinfection requires the disinfection of more than two kinds of disinfectants to prevent the occurrence of drug resistance; the rabbit house should be cleaned frequently, remove the excrement and dirt every day, use damp lime to prevent moisture, keep the house clean and dry, and prevent the accumulation of excrement and reduce it. The production of irritant gases such as ammonia gas and hydrogen sulfide prevents respiratory diseases such as rhinitis and pneumonia. In addition, the disinfection should be serious and the rabbit house should be kept dry. In order to keep warm, the rabbit house in winter has increased hermetically, but with poor ventilation and increased harmful gases such as ammonia gas, hydrogen sulfide, and sulfur dioxide, it is easy to induce retinal diseases such as conjunctivitis and rhinitis. Therefore, ventilation equipment should be installed and automatic ventilation should be strengthened. You can open the doors and windows from 11 noon to 2 pm every day, use the natural wind to change the air, and grasp the smell at any time. In order to make the rabbit safe winter, enhance the body, apply ivermectin or avermectin, insect repellent net and other drugs before winter (late autumn), and take injections or spices to take all rabbits and young rabbits once Extermination of internal and external parasites to prevent the invasion and harm of parasitic diseases.
Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
