Feed costs account for about 60% to 70% of the total chicken production cost, so it is particularly important to improve feed utilization. Here are some effective ways to increase chicken feed utilization:

Scientifically formulated feed. (1) When selecting raw materials and preparing feed, pay attention to the quality and palatability of raw materials. For those feed ingredients that have bad characteristics and poor palatability, such as blood powder, leather powder, feather powder, cotton broth (cake), rapeseed (cake), and sesame Cakes, grass powder, bad residue, etc. must be processed in advance and their use in feed should be limited. (2) The raw materials used should be of good quality, and the raw materials that are moldy and degenerate should not be used as raw materials for compound feed. Also pay attention to those feed ingredients that have not been contaminated with pesticides or other toxic or hazardous substances. (3) Attention should be paid to diversification of feedstuffs, and as many feed ingredients as possible should be used for preparation. This can give full play to the nutritional complementation between various raw materials to ensure the improvement of nutrients and help improve the digestibility and nutrients of feedstuffs. The utilization rate. (4) When formulating feed, it must be based on the digestive physiology of various chickens, select the appropriate feed ingredients to match, especially to control the content of crude fiber in the feed. As the content of crude fiber in the diet increases, daily gain and feed utilization will decrease. The crude fiber content should not exceed 5%.

The processing and modulation of feed should be reasonable. Feed processing and modulation methods have a great influence on feed digestibility. Heat treatment processing such as granulation or extrusion improves the utilization of nutrients and the utilization of feed, if excessive processing will reduce nutrient availability and feed utilization . Heat treatment of soybeans, etc., destroys trypsin inhibitors and improves feed utilization. When the feed mixes, it will stir unevenly, which will reduce the feed digestibility. Feed particle size also has a certain effect on feed utilization. Excessive grain size of feed will reduce feed digestibility. A small feed particle size will reduce palatability and feed intake and increase the incidence of gastric ulcers.

Use scientific feeding methods. Different feed methods, their feed utilization is also different. Dry and wet feeds and liquid feeds have improved feed conversion compared to dry feeds, but higher feed intakes can lead to increased carcass fat. Adequate clean drinking water is also very important for improving feed utilization.

Improve the feeding environment. Environmental conditions can also affect feed conversion efficiency. For example, the optimal temperature for laying hens is 18-20°C. When the temperature decreases, feed intake increases. Most of the feed energy will be used for heat production instead of laying eggs. If the temperature is too high, feed intake decreases. Changes in humidity, ventilation, harmful gases, and light can also affect feed utilization.

Improve the level of feeding and management. Feed management also affects feed utilization. Overcrowding of laying hens can significantly impair production performance, and their feed intake and feed rewards will be reduced. Under house feeding conditions, the production performance of the smaller cohorts was significantly improved. Good manual management will also get better production efficiency.

Do a good job of epidemic prevention and health care. It is necessary to formulate a good anti-epidemic program and manage it according to the procedures so that the production performance of the flock can be maximized. If unhealthy chickens are found in production, they must be treated or eliminated in time.

Appropriate use of feed additives. In the production practice, the use of some enzyme preparations, probiotics, Chinese medicine preparations, etc. can improve the chicken's feed utilization and production performance.
