New management of broilers

Broiler production needs: high daily weight gain and low feed consumption. The best long meat is concentrated on the chest. In short, management and variety are important, but if the balance of feed alone can not achieve this goal. Controlling growth rate: Generally speaking, if the broiler does not limit the feeding, provide enough feed and fresh drinking water, theoretically it should get the best growth rate and quickly reach the market weight. However, in actual cases such as ascites, heart failure syndrome and sudden death, or due to factors such as feed efficiency requirements and market prices, the growth rate is limited. In addition, with the goal of intensive intensive rearing, automation, and marketing, etc., the lighting, restriction, powder, or granular materials are selected to limit their growth. Feed restriction: It is not lighted 24 hours a day.

Some areas only use natural light, and the difference in food intake between the two is not entirely clear. Actual chickens prefer to eat pelleted feed, but also better growth. However, the most commonly used method is limited daily servings. Note: 1 Intermittent light, 1 day divided into 4 cycles, starting at the 3rd age, 2 hours light 4 hours dark. 2 Feed restriction, fixed feed volume, 2 days in the first week and 2 days after 2 weeks. Lighting plan: Lighting in some countries may be more effective than restricted feeding. However, its exact physicochemical mechanism is not known, but if lighting is used to promote growth, it will increase the weak leg and mortality of broilers. Restriction of feeding and lighting in parallel: This two-in-one use has been adopted in the Netherlands to improve feed order and reduce mortality.
