CATDOLL : CATDOLL: There are many feeds for farmed shrimp. What kind of feed is generally used to feed farmed shrimp?

In the breeding and production of white shrimp, the protein content of compound feed reaches 25%~30%, which is enough to meet the growth needs of white shrimp. Too high protein content in feed will not only promote the digestion and absorption of protein by white shrimp, but also increase the internal burden of white shrimp. The part that cannot be completely digested and absorbed will be discharged with feces, which is easy to pollute the water body. This is a problem that should be paid attention to when preparing the feed formula of white shrimp. 1000 grams of multidimensional premix, 3800 grams of 50% choline chloride, 3000 grams of mineral element premix, 750 grams of vitamin C polyphosphate, 140 grams of 25% allicin, 2600 grams of cholesterol, 1200 grams of taurine, 1000 grams of aquatic compound enzyme, 1000 grams of shrimp molting hormone, and 1600 grams of 15% L-carnitine. 500 grams of allicin powder, 5000 grams of HJ-1 adhesive, 800 grams of sodium diacetate, 130 grams of oxygen, 17480 grams of carrier wheat flour, a total of 40 kilograms.

Fermented feed is a kind of biological fermented feed. It uses microorganisms and complex enzymes as fermentation agents, utilizes the metabolism and reproduction of microorganisms, and adopts special production technology for fermentation to convert feed raw materials into microbial proteins, bioactive small peptide amino acids, active probiotics, complex enzymes and organic acids. Fermented feed is different from traditional feed. Its main function is the nutrients produced by biological bacteria. Microbial fermentation technology not only improves the nutritional absorption level of feed, degrades toxins that may exist in feed raw materials, but also produces a large number of beneficial bacteria and fermentation metabolites, which play a strong probiotic function and environmental improvement function. The fermented feed has great application value and many functional characteristics. At present, the main known functional characteristics are:

The fermented feed has a high organic acid content, low pH (about 4.5), and contains more lactic acid and acetic acid. At the same time, the fermented feed contains a large number of microbial active probiotics, which can reach 109 CFU/g. The fermented feed can acidify the intestines, reduce the pH value of the intestines, improve the microecological environment in the intestines, inhibit the growth and reproduction of harmful bacteria, promote digestion, and reduce intestinal diseases. During the feed fermentation process, a large number of fermentation metabolites, such as biological enzymes, antimicrobial peptides, organic acids, phenolic antioxidant active substances, polysaccharides, slag-buried growth factors, multi-dimensional, multi-minerals, trace elements, etc., are necessary for animal growth and physiological activities, have strong probiotic functions, improve animal immunity, and promote the healthy growth and development of animals.

Beneficial bacteria and their fermentation products in fermented feed can improve the digestion and absorption rate of nutrients in feed, thereby reducing the pollution of nitrogen in feces to the bottom water quality of the pond and improving the pond breeding environment. After the feed is fermented, microorganisms and enzymes break down the feed into small molecules such as glucose and amino acids. , which are easily digested and absorbed by animals, degrading or eliminating the anti-nutritional factors in the raw materials, thereby 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 the feed. Formula A is the most commonly used shrimp feed formula with the most common raw materials. Of course, 1% shrimp premix, soybean lecithin and other additives are also used. If you want to breed pollution-free green lactic acid bacteria shrimp products and supply them to high-end diners and hotels, of course, don't use these two additives, just mix the other raw materials directly, and pay attention to check the authenticity of the fish meal. Formula B means that you can buy a lot of scraps from meat processing plants, such as dried pork, dried beef, dried chicken, dried fish scraps, dried ham, etc. , so you can use formula B.

Of course, it is fed with cracked feed specially for feeding shrimps, but the quality must be good. Do not use some poor quality feed. It is necessary to feed with small meals and frequent meals, which is beneficial to the growth of shrimps.

Generally speaking, bait is used, and it is best to use basic bait, which means that fertilizer should be applied in advance. These organisms can purify the water quality.

Because shrimp are omnivorous, you can choose to feed them with feed containing fish meal, soybean meal, and wheat bran. Of course, if conditions permit, you can also feed them with worms, aquatic insects, and algae.
