First, the quality of the chicks, to ensure health, to ensure good hatching work if the incubation temperature is too high or too low, too high or too small humidity, inadequate ventilation, long time of hatching, poor health of the hatchery or other unreasonable process will This leads to low quality chicks, which in turn affects broiler production. Pay attention to the transportation link. If there is no ventilation in the transportation vehicle or there is a dead angle in the ventilation, the chicks may be overheated, dehydrated or deprived of oxygen. In the cold season, if the transportation vehicle does not have heating equipment such as air conditioning, the chicks often suffer from cold stress or excessive heat preservation. Hermetic causes hypoxia.

Second, feed nutrition, as we all know, to make the broiler fast growth, high feed conversion rate of the characteristics of excellent varieties to be played, the broiler chickens need to feed high-energy high-protein full-price feed. Today's broiler feed formulators can easily design full-price feeds for the nutrients needed for each stage of growth in broilers.

Third, the environmental status of the chicken house

1. Temperature, the ambient temperature of 1 day old chicks is controlled at 33 °C ~ 34 °C. At 7 days of age, the ambient temperature was lowered to 30 ° C to 31 ° C. Later, as the chick ages, the temperature drops by 2 ° C to 3 ° C per week, and the temperature of the house is controlled to be 19 ° C to 20 ° C when the age is 35 days. Special emphasis is placed on gradually reducing the ambient temperature of the house, so that the temperature difference of the house is not more than 1 °C per day, so as to avoid cold stress.

2. Humidity, the humidity of broilers in the first week is controlled at 60% to 65%. Later, with the increase of age, the humidity is controlled within the range of 50% to 70% in chicken battery cages .
