1、 The function of benzoic acid
Benzoic acid is a feed additive commonly used in the field of poultry feed. The use of benzoic acid in chicken feed can have the following effects:

1. Improve feed quality: Benzoic acid has anti mold and antibacterial effects. Adding benzoic acid to feed can effectively control microbial deterioration, prolong the storage time of feed, and improve the quality of feed.
2. Promoting the growth and development of laying hens: During the growth and development period, laying hens need to absorb a large amount of nutrients. Benzoic acid can promote the absorption and utilization of nutrients by laying hens, accelerating their growth and development.
3. Promote protein synthesis: Benzoic acid can increase the utilization rate of protein in laying hens, promote protein conversion and synthesis, and thus improve protein utilization efficiency.

4. Improve egg yield and quality: Benzoic acid can promote ovarian development in laying hens, enhance protein and calcium absorption and utilization, and increase egg yield and quality.
2、 Application of benzoic acid
When using benzoic acid in chicken feed, the following points should be noted:
1. Reasonable dosage: The dosage of benzoic acid should be determined according to specific feed types, growth stages, and environmental conditions, and should be used in accordance with the manufacturer's instructions.
2. Combination with other feed additives: Benzoic acid can be used in combination with other feed additives such as probiotics, phytase, etc. to better exert its effects.
3. Pay attention to storage and preservation: Benzoic acid is a white crystalline substance that is prone to moisture absorption. It should be kept dry and stored in a cool, dry place.
4. Reasonable combination of feed: Benzoic acid can be reasonably combined with other feed ingredients such as wheat bran, corn, soybean meal, etc. to achieve better results.

In summary, the application of benzoic acid in chicken feed can have a good effect, but attention should be paid to the usage method and dosage to avoid adverse effects on the health of laying hens.
