In the cold winter and early spring, beef cows need the sun and the most suitable temperature to ensure nutrients. The best way to meet the needs is to keep the beef cattle in a plastic greenhouse.
The temperature in the plastic greenhouse is about 10C higher than that of a typical cowshed. According to the experiment, in the case of feeding the same feed, the average daily weight gain of beef cattle raised in the greenhouse was 1175 grams over 3 months (90 days), compared to the low temperature of beef cattle raised in the general cowhouse. Not only did it not gain weight, but the average daily weight loss was 125 grams. The construction of plastic greenhouses can be based on the number, size and existing
The actual situation of the cowshed is determined. The open or semi-open cowshed can be closed with plastic film to open the part, and the temperature inside the house can be increased by the heat of sunlight and the heat emitted by the body's own body temperature.
The greenhouse should be built on the sunny side of the leeward, high dry terrain. If you want to rely on the north wall in the courtyard, make it face south to the south, in order to increase the lighting time and light intensity, help to increase the temperature, must not be built in the south wall root. The plastic film used can choose white transparent plastic film, thickness 0.02 ~ 0.04 mm. Shelving materials should be adapted to local conditions, such as wooden poles, bamboo poles, and steel bars. Cold-proof materials include straw, cotton, and sacks. Warm roof type can be flat roof type, single slope type or flat arch type. Practice has proved that the joint type (basically double slope type, but the north wall is higher than the south wall, the roof is asymmetrical) warm shed is good, its advantage is that the shed has a small area, adequate light, no water, easy to keep warm, save Industrial materials.
For the construction of plastic sheds, first determine the appropriate shed time, according to the length of the frost-free period of flexible grasp, in the south can be later, the northern region can be earlier. The general buckle time is from November to March of the following year. When the shed is draped, the plastic film should be stretched and flattened, sealed on all four sides, and be airtight; at night and in rainy and snowy weather, straw, cotton curtains, sacks, and other materials should be used to keep the warm shed tightly and keep warm, and the sheds should be promptly removed. Frost and snow accumulation to ensure good lighting
The feces in the house should be cleared regularly every day to ensure that the inside of the greenhouse is clean and dry.
In order to ensure fresh air in the shed, the ventilation shed must be provided with ventilation holes or ventilation windows. When conditions permit, ventilation fans should be installed to remove excessive moisture and maintain suitable humidity and temperature in the house. The inlet is generally located at the lower part of the south wall of the greenhouse. The vent hole is located on the upper part of the 1/2 or plastic shed. Ventilation twice a day, every 10 minutes or so. It is advisable for fattening beef cattle to occupy 5 to 5.5 square meters per cow in the shed. In the warm shed, it is best to use a cow, a cow, a trough, and a short rope to fasten the cows. After the cow eats the hay, the cow can rest, cuddle, and enjoy the sun. In such an environment, it is inevitable that beef cattle will increase their fast and long meat.
