The organism has a certain inertia. If the living environment around it or the source of food and the type change, it will have a certain degree of influence on the body. Therefore, it is not recommended that you change the type of feed during the breeding process. If this situation cannot be avoided, you should gradually change the type of feed and gradually complete the feed change. Let's take the laying hen as an example to explain the precautions for changing the feed.
Normally, the feed used by young chickens and laying hens is different. If the young chickens are suddenly refueled, the crude protein and calcium content of the body will rise rapidly, which will lead to an increase in the drinking water of the chickens, and symptoms such as collective indigestion and diarrhea. Therefore, when changing the feed for young chickens, pay attention to the content of crude protein and calcium in the feed: crude protein is about 15.5%, and calcium is about 0.8%.
Because the demand for crude protein and calcium is higher in laying hens, it is better to change to the laying hens when the egg production rate reaches 2% to 5% when replacing the feed. The calcium content of the laying hens should be 3.4. % to 3.5%, containing 18% crude protein.
If it is a young chicken cultivated by natural light after the summer, it is often started late, and it can be refueled at 18 weeks of age. If it is a reserve chicken cultivated with natural light after winter, it is often opened earlier, at 17 weeks. Refueling; generally for 19- to 20-week-old chickens for feeding pre-feeding materials, also called transition materials, the calcium and protein components in the feed should be increased compared to the feed of young chickens, the ratio of calcium is generally 1 %, the crude protein is 16.5%. When refueling, the refueling process is gradually completed in about half a month, and the material cannot be suddenly refueled.
