What are the precautions for formulating complete chicken feed?
1. Make full use of local feed resources. Because the crop varieties grown in different regions are different, the types of feed are also different. In the spirit of adapting to local conditions and using local materials, local feed resources should be fully utilized, especially those low-priced feeds, which should be used more rationally. This can reduce intermediate links, which can not only reduce the freight costs required for large-scale grain transportation, but also ensure the source of feed. According to surveys, this measure alone can reduce feed costs by 3%-5%. It is one of the effective measures to improve @#@230@#@ economic benefits.
2. Raw material varieties should be diversified. When mixing feed, use as many types of feed raw materials as possible to achieve diversification, which can produce a complementary effect among feeds. It can not only improve the biological value of protein in the feed, but also improve the palatability of the feed, increase feed intake, improve the production performance of the flock, and maintain stable and high production. Hence the proverb, "Diversified feed, more and bigger eggs."
3. Keep the feed formula relatively stable. When preparing mixed feed, while meeting various nutritional requirements, the feed varieties and mixing proportions should also be kept relatively stable. Do not suddenly change feed varieties and mixing proportions. Because chickens are very sensitive to feed changes, suddenly changing the feed formula or replacing a certain feed will reduce feed intake and cause egg production to drop rapidly. This is what people mean by "poor feed means no eggs." Because of the composition, nutritional value, and price of feed raw materials, feed changes are frequent, so it can only be said that the variety and mixing proportions of feed raw materials should be kept relatively stable; absolute stability is very difficult to achieve. When maintaining relative feed stability, if you plan to replace feed or mixing proportions, the changes should be made gradually to prevent unnecessary losses. How to change feed gradually should depend on the extent of the formula change. Only by gradually replacing feed in this way and allowing the flock to gradually adapt to new feed varieties and new feed formulas can the flock maintain stable and high production.
4. Pay attention to feed hygiene. All countries in the world pay great attention to feed hygiene, because feeding feed that does not meet hygiene standards not only affects the health and production performance of the flock, but its products (meat and eggs) can also directly or indirectly harm human health.
