In winter, the cattle are in a state of pure consumption of feed, and the feed utilization rate and the slaughter rate are very low, thus forming a vicious cycle of “summer fullness, autumn fat, winter thin, and lack of springâ€. After one winter, the loss of up to 25% can be achieved. 30%. To solve this problem, take the following measures.
1. Pay attention to the heat insulation performance of the cowhouse. No leakage, no wind, the ground is not humid, clean, and the room temperature is maintained at 10 °C and 18 °C.
2. Cowshed ventilation Because the winter warm sheds are closed tightly, the temperature difference inside and outside the house is large, coupled with cattle breathing heat, excrement and excrement and other reasons caused by the humidity within the house, ammonia, carbon dioxide, hydrogen sulfide and other harmful gases are too high, affecting cattle The normal growth and development. Therefore, ventilation must be performed in a timely manner.
3. Maintain hygiene To maintain the hygiene of the warm shed, it is necessary to ensure the normal growth and development of beef cattle. The specific measures are: to remove cow dung every day when feeding cows; to clean the cowshed and the feeding trough; to sweep the leftovers after feeding the cows every day; to clean the feed trough in time; to disinfect the cowsheds once a month, using 1 % concentration of sodium hydroxide solution for disinfection of the floor and walls of the barn, when the strong ammonia smell is disinfected with peracetic acid, the cowshed door can be disinfected with quicklime.
4. Scientific feeding of feeds is the material basis for fattening cattle, beef, and long meat, and must be properly matched. The diets were 5 kg of dried grass, 8 kg of corn silage, 3 kg of corn flour, 0.5 kg of bean cake, 100 g of urea and 50 g of salt. Feed three times a day, that is, 6 o'clock in the morning, 12 o'clock noon, and 6 o'clock in the afternoon.
