Formulation of nutrition standards——Key points for production technology of laying hen feed(2)

1. Nutritional standards based on laying hen breeds

The basic nutritional standards of laying hens of different quality and body types are quite different. Therefore, when formulating formulas for large-scale laying hen farms, it is necessary to fully understand the nutritional standards of the breeds of laying hens that they breed. Supply laying hen breeding standards and management points.

2. Formulation of nutrition standards based on laying hens

Laying hens have different breeding purposes at different stages, and their nutritional requirements are different. Therefore, the formula design should be strictly in accordance with the nutritional standards of each stage to meet the corresponding needs of the laying hens at each growth stage.

3. Formulate nutrition standards based on the daily feed intake of laying hens

The feed intake of the laying hens directly determines the nutritional standards of the laying hens, and the daily nutrients must satisfy the growth and production needs of the corresponding laying hens.

4.Adjust and develop standards based on changes in the breeding environment

In the case of changes in the breeding environment (excessive ammonia concentration, heat and cold stress, swarm stress, disease prevention epidemic stress, etc.), the formulation of standards should take into account the nutritional stress compensation needs. Increase nutrition standards accordingly.

5. Formulate nutrition standards according to breeding models

The nutritional requirements of breeding density, caged or flat-fed, and free-range laying hens are quite different, so the corresponding nutrition standard should be determined according to the breeding mode.
