Floating fermented soft pellet feed with ultra-large particle size

Abstract

The invention relates to a fermented floating soft pellet feed with an ultra-large particle size. The feed consists of the following components in parts by weight: 30-40 parts of fish meal, 20-30 parts of chicken meal, 5-10 parts of shrimp paste, 2-5 parts of spray-dried animal blood cells, 5-10 parts of soybean meal, 10-15 parts of cottonseed meal, 5-10 parts of cassava starch, 3-5 parts of vital gluten, 10-15 parts of high gluten flour, 1 part of a vitamin and mineral premix, 1-2 parts of monocalcium phosphate, 2-4 parts of soybean oil, 2-4 parts of fish oil and 0.5-1 part of water. The feed has the advantages that the expanded feed with the ultra-large particle size is used as a fermentation substrate of beneficial microorganisms, the protein structure is changed into a loose state through expansion and extrusion, small peptide and peptone substances are easily generated under the action of the microorganisms and digestive enzymes, the digestion and absorption rate of feed protein is increased, the palatability of micropterus salmoides is met, and the feed is good in cohesiveness and not prone to breakage and agglomeration.

Description

technical field [0001] The invention belongs to the field of biological fermented feed preparation, and in particular relates to a fermented buoyant soft granular feed with super large particle size. Background technique [0002] With the increasing scale, intensification and industrialization of the aquaculture industry, the accumulation of harmful pollutants in the aquaculture process has seriously damaged the ecological environment of the aquaculture water body, resulting in increased stress and decreased immunity of aquaculture animals, and various aquaculture diseases Frequent occurrence seriously restricts the sustainable and healthy development of the aquaculture industry. [0003] Since the 1950s, with many countries in the world restricting or prohibiting the use of antibiotics in feed, finding new alternatives to antibiotics has become an urgent task. Probiotic fermented feed is a kind of feed that integrates the efficacy of probiotics and the advantages of high-q...

Problems solved by technology

[0004] Most feeds are dry and hard feeds, such as dry feeds in the form of granules, powders, and tablets. Dry feeds are good for preservation, but dry feeds are prone to loss of nutrients and damage to heat-sensitive substances during the drying process of wet soft raw materials. highly toxic, such as microorganisms, enzyme preparations and vitamins, etc.; the drying cost is high, and the dry feed has poor palatability and is not easy to absorb

[0005] At present, the particle size of fermented buoyant soft pellet feed is small, which is not suitable for some aquaculture animals that require large particle size fermented buoyant feed, such as California sea bass. Making super large particle size fermented buoyant soft pellet feed is easy to sink and stick. Poor coagulation, agglomeration into lumps, so it is necessary to develop super-large particle size fermented soft pellet feed that can float in water
