Scientific preparation of feed generally 0 weeks of age to 4 weeks of age of chicken feed should contain 20% to 21% of crude protein per kilogram; 5 weeks of age of broiler feed should contain crude protein 18% to 19% per kilogram, calcium accounting 1%, phosphorus 0.65%, but also pay special attention to the balance of various amino acids in the diet to meet the chicken's growth and development needs.
Adjust the appropriate temperature and light to keep warm in the chicken house in winter. In hot days, it is necessary to do a good job of ventilation and cooling in the house. The best temperature is between 21°C and 24°C. In recent years, the use of “two light and two dark†lighting methods has been widely applied in chicken farmers. The specific approach is: using 2 hours of light, 2 hours of dark lighting, can not only ensure the feed intake of chickens, but also can save power consumption, so that the activities and rest of broilers amount. To increase the lighting, install incandescent lamps at an illumination intensity of 2 watts to 2.5 watts per square metre, or install fluorescent lamps with an illumination intensity of 1 watt to 1.5 watts.
It is advisable to feed pelleted broilers with reasonable feed. If feeding dry powder, it is advisable to eat less. Have enough feed troughs and drinkers. Generally, chickens of more than 2 weeks of age should have a 1-meter long trough for every 30 to 40 birds, and a 1-meter-long drinking fountain for every 70 to 80 eggs, which can reduce feed consumption.
Reducing Feed Waste Feeding broiler chickens should be done less frequently and try to keep the tanks free of leftovers or leftovers. Buy full-grain pellet feed to avoid chicken picky eaters. The feed is fresh, not too much for one purchase or self-distribution, and it is better to use it once a week. In the self-dosing, under the conditions of ensuring nutrition, choose raw materials with low local prices as much as possible to reduce costs. To prevent rat damage, add grit to help digestion.
We must adhere to the principle of "giving priority to prevention and focusing on prevention" in order to do a good job of prevention and control of epidemics. According to the epidemic characteristics of the local epidemics, vaccination and preventive drug administration were carried out on time, especially the prevention and treatment of chronic diseases, such as in vitro and in vivo parasites, mild coccidiosis and malabsorption syndromes, and chronic respiratory diseases.
