1. Scientific Application of Feed Materials
The amount of crude protein and energy in the diet should be determined according to the nutritional needs, adhere to the standard of meeting the needs, make the best use of feed raw materials, reduce waste, and scientifically adjust the feed ratio. For example, the crude protein content in feed should be kept at 15% in the early laying period, while the peak laying period should be kept at about 16.5%.
2. Accurate use of minerals
The principle of mineral action must be fully and correctly understood. The excessive or insufficient use of minerals will bring great losses to the production of laying hens. Practice has proved that the content and proportion of feed must be emphasized in the preparation of feed. For example, calcium and phosphorus in laying hen feed should be 3.6% and 0.45%, and the ratio of calcium and phosphorus in chicken feed should be kept at (1.5-2.0):1.
3. Regulate the use of vitamins
Some farmers do not use vitamin products, but use green fodder (such as alfalfa, vegetables, carrots) instead of vitamins, which is not suitable for large-scale feeding. The main problem is that vitamin supplementation is not comprehensive, adding time is uncertain, sometimes no, at the same time, too much green feed intake will directly affect the normal intake of chickens. Therefore, multi-vitamin additives should be used instead of green fodder, but green fodder can be used as vitamin supplement.
4. Correct Design of Feed Formula
Whether the feed formulation is designed properly or not directly affects the egg production. For the design of feed formula, the general requirements are according to different breeds of chickens, different stages of growth and development, different stages of laying eggs, etc. In addition, appropriate adjustments should be made according to the growth status of chicken flocks, feed raw material supply, market conditions and seasons.
