According to different uses and different nutritional needs are roughly divided into the following categories:

1. Supplement and balance nutrition: including amino acids, vitamins, trace minerals and non-protein nitrides.

2. Health care and growth-promoting agents: Feed additives that individually or in combination have the functions of antibacterial, disease-preventing, anthelmintic, promotion of feed nutrient utilization, and promotion of animal growth, egg production, and milk production. Including: antibiotics, synthetic antibiotics, insect repellents.

3. Physiological metabolism regulators: 1 anti-stress categories: chlorpromazine, vitamin C and so on. 2 Chinese herbal medicines.

4. Promote appetite to help digestion: including acidifiers, sweeteners, umami agents, spices, biocides (probiotics), enzymes and buffers.

5. Feed processing and preservatives: including anti-mold agents, antioxidants, binders, anti-caking agents, emulsifiers, and silage preservatives.

6. Other categories: including colorants, feed pigments, activated carbon, zeolites, medical stone, bentonite, nitrate and other rare earth.

The correct use of feed additives

1. Clear use purpose. Whether it is a nutritional feed additive or a non-nutritive feed additive.

2. To have a comparative selection of varieties. At present, there are many manufacturers of feed additives, and the variety is complex. First of all, it is necessary to select more well-known manufacturers and purchase them from high-reputation operating companies. Secondly, it is necessary to use them comparatively, not only for price but also for results.

3. Reasonable and standardized use. For feed additives, except for some types that are used exclusively for drinking water, such as instant multi-dimensions, most of them can only be mixed and fed in dry materials. Adding them to wet materials or water can greatly reduce the use effect. Therefore, they cannot be changed easily. Use method. When using, strictly according to the ratio, stirring evenly; more varieties of application of attention to compatibility in taboos, but also careful observation of livestock and poultry, if found abnormal phenomenon, immediately stop feeding.

Misuse of feed additives

1. Think the price is as expensive as possible. The quality and effectiveness of the expensive additives are generally good, but they cannot blindly follow the price. The key to the choice should be the quality of feeding.

2. It is considered that the more amount added, the better. In fact, if the amount is too much, it will not only cause waste, but also affect the production performance of livestock and poultry, and it can also cause serious poisoning. Therefore, the additive amount must be moderate.

3. Only one additive is used throughout the feeding period. Different stages of animal growth require different types of nutrients, which require different types of additives. For example, layer chicks are divided into brooding period, breeding period, and egg production period. Pigs are divided into piglets and finishing pigs. If only one additive is used throughout the feeding period, the desired effect is not achieved.

4. Blindly mix a variety of additives. Blind multi-species mixed use of additives will not only make some nutrients repeated, resulting in serious excessive and excessive, and due to antagonism between nutrients, some nutrients will be destroyed, such as iron ions can quickly destroy vitamin D and vitamin K. Therefore, in the use of feed additives should be a reasonable match, can not be blindly abused.

5. Oppose the use of additives. The purpose of use of additives is to supplement the deficiency of certain nutrient elements, rather than the more the better, but to achieve a comprehensive nutritional balance, so as to improve the utilization rate of feed and conversion rate
