In the cold winter and early spring, beef cattle are bred with plastic sheds, because the temperature in the shed is about 10 degrees Celsius higher than the average shed, beef cattle grow well, and in the case of feeding the same feed, through 3 months of feeding, The average daily gain of beef cattle raised in the greenhouse is nearly 1200 grams. In general, the temperature of beef cattle raised in the cowshed is not only not increased, but also averaged 125 grams per day. The economic benefits are significant and worth promoting. The greenhouse should be leeward, sunny, high and dry. If you are in the courtyard, you must rely on the north wall to make it face south to increase the lighting time and light intensity, which will help increase the temperature of the building and must not be built on the south wall. The plastic film used can choose white transparent plastic film, thickness 0.02 mm - 0.05 mm. Shelving materials should be adapted to local conditions, such as wooden poles, bamboo poles, lead wires, and steel bars. Cold-proof materials used straw, cotton curtains, sacks, etc. can be. There are many types of warm shed roofs, such as flat top, single slope, and double slope. Practice has proved that the north wall is better than the south wall. Its advantage is that the area of ​​the shed is small, the light is sufficient, there is no water accumulation, and it is easy to keep warm. The construction of plastic sheds will first determine the appropriate time for the shed, and will be able to flexibly grasp the length of the frost-free period. The general buckle time is from November to March of the following year. When buckled, the plastic film should be tightened and leveled, sealed on all four sides, and be airtight. At night and in rainy and snowy weather, we must use straws, cotton curtains, or sacks to keep the greenhouses warm and keep warm, and remove the frost and snow in the shelters in time to ensure good lighting. In order to ensure fresh air in the shed, ventilation holes or ventilation windows must be provided in the shed. Generally, the air inlet is located on the upper part of the south wall of the greenhouse or on the plastic shed. Ventilation twice a day, about 10 minutes each time. It is advisable for fattened beef cattle to occupy 5-6 square meters per cow in the shed. In the warm shed, it is best to practice a method with a cow, a cow, a trough, and a short rope. After the cow eats the fodder, he can rest, cuddle, and sun under a reliable pile or trough. In this kind of environment, of course, beef cattle grow quickly.
