At present, the broiler raising method commonly adopted by breeders is not limited to feed, and gives light day and night, resulting in a variety of metabolic diseases, such as ascites, sudden death, and leg problems. In order to prevent the occurrence of these diseases, farmers blindly add drugs to the feed, which not only results in drug residues in the slaughterhouses, but also increases the cost of feeding. According to the production practice for many years, the author bred broilers in stages and received good results. The broilers are 0-14 days old and provide the chicks with high-quality drinking water in the first few days after hatching, such as 5% glucose + super multi-dimensional + high-efficiency and low-toxicity antibacterial drugs, and provide full-price matching with small volume and easy digestion. Feed, so do less feed Tim. The first day can be used 24 hours light, light intensity of 4 watts per square meter, then gradually reduce the lighting time, and eventually transition to the natural lighting time. The implementation of this lightening system, which has gradually decreased first and then increased, can promote the development of internal organs and bone calcification of chicks to a certain extent, make them in good health and reduce the incidence of diseases. Broiler 10 to 35 days old, according to the growth of broilers, appropriate to increase the volume of feed, in order to reduce the energy and crude protein concentration in the feed, generally can be reduced by about 10%, but the feed in a variety of vitamins, microelements and minerals Substances should be supplied as standard or slightly higher than the standard. Regular feeding 3 times a day, pay attention to strengthen the broiler movement, such as the night can be used to drive the broiler chicken gently or increase the light intensity in the house to reduce the weight of the chest caused by the pressure and reduce disease. Broilers are used for short-term fattening using high-quality feeds from the 36th day of age to slaughter. When preparing feedstuffs, attention should be paid to: (1) Diversification of raw materials and low fibrosis. (2) Add 3% to 5% of animal and vegetable fats and oils in the feed to increase the energy level of the diet. (3) Feeding as much as possible with pellets. The number of feedings is increased from 3 times a day to 5 times a day. Feeding can also be done throughout the day to allow the birds to feed freely. (4) Adjust the breeding density. Excessive breeding density not only restricts the intake of food, but also affects the rest and causes uneven growth and development of chickens. It also causes air pollution in the homes, deterioration of the environment, and induces many diseases. Under normal circumstances, the broiler breeding density in the winter is 12 to 15/m2, and the summer bred density is 8 to 10/m2. In addition, we must pay attention to strengthening the ventilation of the coop, keep the air fresh and temperature and humidity suitable, the temperature is appropriate to about 18 °C, relative humidity of 55% is appropriate.
