Matching chicken diet

1. The type of feed used should be as diverse as possible. Under possible conditions, the types of feed used for compounding should be as diverse as possible to facilitate the complementarity and balance of nutrients. Increase the nutritional value and utilization of the entire diet. Many varieties of feed can also improve the palatability of feed, increase the feed intake of chickens, and ensure stable production and increase production of chickens.

2, consider the chicken's digestive physiology characteristics reasonable ingredients. For example, chickens have low digestibility of roughage. Crude fiber content in chicken diets should not be too high, generally should not exceed 5%. Otherwise it will reduce the digestibility and nutritional value of the feed.

3. Pay attention to the quality and palatability of the diet. Do not use ingredients that have irritating odors, mildew, or other harmful substances to make feed. There are two aspects that affect the palatability of feed: on the one hand, it is the cause of the feed itself, and if the sorghum contains tannins, excessive feeding will affect the feed intake of the chicken. therefore. Take 5% to 10% of the diet as appropriate. On the other hand, it is caused by processing. If pressed into pellets, the palatability can be improved. The feed powder is too finely ground and the chicken will stick out and it will reduce the palatability. Therefore, the powder can not be too fine, the size of a variety of feed should be basically the same, so as not to picky chicken.

4. The diet should remain relatively stable. If it is really necessary to change, it should be gradually replaced, preferably a one-week transition period in order to avoid stress, affect appetite, reduce production performance. Especially for laying hens, we must pay attention to the relative stability of feed.

5, reference and flexible application of feeding standards. Feeding standards are the basic basis for scientific breeding of chickens. However, in practical applications, they should be flexibly adjusted according to the specific conditions of local chicken breeds, gender, regional environmental conditions, feed conditions, and production performance, and appropriate adjustments should be made to make the most suitable conditions. The amount of nutrients needed. Finally, actual feeding is used to adjust the feeding effect.

6. When choosing feed, economic principles should be considered. To use nutrient-rich, low-cost and easy-to-feed feeds as much as possible, pay attention to local conditions, adapt to local conditions, and maximize local feed resources. For example, under the premise of satisfying the requirements of major nutrients, try to use low-cost and reliable sources of green feed, sweet potatoes, pumpkins, potatoes, etc. instead of a part of grain feed to reduce the cost of feeding.

7, correctly estimate the nutritional value of feed. The same kind of feed, due to different production areas or different harvest season, its nutrient composition may also have large differences. Therefore, when formulating diets, it is necessary to use a chicken feed nutrient composition table that is in line with the actual conditions in the country to correctly estimate the nutritional value of various feeds, and it is better to measure the amount of feeds that are large and important.
