There are many farmed shrimp feed, farmed shrimp generally fed with what feed?

In the culture and production of South American white shrimp, with the protein content of the feed to 25% to 30%, enough to meet the growth needs of South American white shrimp. Feed protein content is too high, will not only promote the South American white shrimp digestion and absorption of protein, but also increase the internal burden of the South American white shrimp, can not be fully digested and absorbed part will be discharged with the feces, easy to pollute the water body. This is the preparation of South American white shrimp feed formula should pay attention to the problem. Multi-dimensional premix 1000 grams, 50% choline chloride 3800 grams, mineral element premix 3000 grams, vitamin C polyphosphate 750 grams, 25% allicin 140 grams, 2600 grams of cholesterol, taurine 1200 grams, aquatic composite enzymes 1000 grams, shrimp moulting hormone 1000 grams, 15% L-carnitine 1600 grams. Allicin powder 500 grams, HJ-1 binder 5000 grams, sodium bisacetate 800 grams, 130 grams of oxygen, carrier wheat flour 17,480 grams, **** 40 kilograms.

Fermented feed is a kind of bio-fermented feed, which takes microorganisms and compound enzyme as the fermenting agent, utilizes the metabolism and reproduction of microorganisms, and adopts the special production technology for fermentation, and transforms the feed materials into microbial protein, bioactive small peptide amino acid, active probiotics, compound enzyme and organic acid. Fermented feed differs from traditional feed in that its main function is the nutrients produced by biological bacteria. Microbial fermentation technology not only improves the nutrient absorption level of the feed and degrades the toxins that may exist in the feed material, but also produces a large number of beneficial bacteria and fermentation metabolites, which exerts a strong probiotic function and environmental improvement function. The resulting fermented feeds have great application value and many functional characteristics. At present, the main functional characteristics are known:

The fermented feed has high organic acid content, low pH (about 4.5), and contains more lactic acid and acetic acid. At the same time, fermented feed contains a large number of microbial active probiotics up to 109 CFU/g. Fermented feed can acidify the intestinal tract, lower the pH value of the intestinal tract, improve the micro-ecological environment in the intestinal tract, inhibit the growth and reproduction of harmful bacteria, promote digestion, and reduce intestinal diseases. In the process of feed fermentation, a large number of fermentation metabolites, such as biological enzymes, antimicrobial peptides, organic acids, phenolic antioxidant active substances, polysaccharides, growth factors, multi-dimensional, multi-mineral, trace elements and so on. These products are essential for animal growth and physiological activities, and have a strong probiotic function to improve animal immunity and promote healthy animal growth and development.

The beneficial bacteria in fermented feed and their fermentation products can improve the digestibility and absorption rate of the nutrients in the feed, thus reducing the nitrogen in the feces on the bottom of the pond water pollution and improving the pond breeding environment. After feed fermentation, microorganisms and enzymes decompose the feed into small molecules such as glucose and amino acids. It is easy to be digested and absorbed by animals, and degrades or eliminates the anti-nutritional factors existing in the raw materials, thus improving the nutritional value and utilization rate of the feed. Fermented feed has a natural fermented flavor, good feeding effect and can significantly improve the palatability of feed. Formula A is the most commonly used shrimp feed formula with the most common ingredients. Of course, 1% shrimp premix, soy lecithin and other additives are also used. If you want to farm pollution-free green lactic acid bacteria shrimp products, supply to high-end diners hotel, of course, do not use these two additives, directly mix the other ingredients can be, pay attention to check the authenticity of fish meal. Formula B means that you can buy a lot of meat processing plant scraps, such as dried pork, dried beef, dried chicken, dried fish scraps, dried ham sausage and so on. So you can use recipe B.
