Aquaculture premix formulation design

Premix formulations should be based on the nutritional needs of fish, seasonal changes, changes in the stage, different regions, different varieties, the latest technology and product information, design and adjustment of different formulations, so that the premix formulations always close to the actual production .
1. Formulation design of vitamins (1) Effects of the fish itself. The Vitamin C cannot be synthesized in fish and must be added. Choline, inositol and nicotinic acid are added more than other vitamins. Different fish species and different stages of the same fish require different amounts of vitamins. About 15 kinds of vitamins are needed for warm-water fish, and cold-water fish also requires para-aminobenzoic acid.
(2) The effects of disease and stress. The occurrence of diseases and stress will lead to an increase in the activity of the enzyme system in the body. Intestinal parasites and bacteria often disrupt normal absorption functions and compete for vitamin use; both the excretion and degradation of toxins produced by viruses and bacteria in the body can lead to increased demand for vitamins.
(3) The effect of vitamin K resistance. Choline easily absorbs moisture and destroys other vitamins. It and vitamin C cannot be directly mixed with other vitamins, nor can they be directly mixed with inorganic salts.
(4) The influence of external factors. Under the action of alkali, light, water, and heat, vitamins are easily destroyed. In addition, packaging, storage, and processing methods also have a great influence on vitamins.
Therefore, the amount of vitamin added is higher than its minimum requirement, which is usually more than twice the minimum requirement.
2. Formulation design of macroelements, trace elements, drugs, and amino acids (1) Fish need more calcium and phosphorus, and there is enough calcium in the water for the fish, so only a small amount of calcium needs to be added to the premix. To add a certain amount of phosphorus. Calcium, phosphorus, and magnesium are involved in the formation of bones, but attention should be paid to the amount of these three substances. When the amount of calcium is excessive, the absorption and utilization of magnesium, iron, iodine, copper, manganese, and zinc can be reduced. When the amount of phosphorus increases, the absorption and utilization of iron decreases.
(2) Note the amount of trace elements zinc, selenium, manganese, iron, copper, and iodine to prevent the occurrence of anti-cancer effects.
(3) The compatibility of drugs must be actively combined with the actual situation in the local area to achieve the right results.
(4) The Amino Acid levels must match the varieties and amino acid levels of the bulk raw materials in the full feed.
3. Carrier and dilution options. Carriers and diluents play an important role in premixes, and should be selected from the aspects of moisture content, specific gravity, fineness, flowability, acid reduction, and electrostatic adsorption.

Amino Acid

Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
