Problems solved by technology

[0004] Although existing studies have proved that high-carbon alcohols as feed can have a certain effect on promoting animal growth, however, in the production practice of aquatic animals, another problem that affects animal production performance is the hypoxia tolerance of aquatic animals

Embodiment 1-6

[0030] Three, embodiment 1-6 concrete test method

[0031] (1) Feed preparation

[0032] According to the formula of the feed, all raw materials are fully pulverized by a pulverizer, passed through a 40-mesh sieve, prepared according to the formula ratio, added an appropriate amount of water, fully mixed with a mixer, and extruded into long strips with a particle size of 1.2mm by a meat grinder. , air-dried at room temperature, and then crushed into small pellets that can pass 2.5 to 8 meshes with a pulverizer, and placed in a -10°C freezer for sealed storage for later use.

[0033] (2) Feeding management

[0034] Shrimp seedlings with relatively neat specifications and strong mobility with an average tail weight of 0.091±0.016 grams were selected as experimental shrimps, and the indoor repeated circulation flow-water culture system was used for breeding. The system consisted of 30 sets of 80×50×30cm 3 It consists of a rectangular glass tank with a water storage capacity of ...

Abstract

The present invention discloses an aquatic animal feed additive and an application thereof. The aquatic animal feed additive comprises fatty alcohol potassium phosphate. The aquatic animal feed additive can be applied in feeds. The aquatic animal feed additive has advantages of being simple in formula, effectively reducing asphyxiation point of aquatic animals, enhancing stress resistance abilityof the aquatic animals, improving survival rate and feed utilization rate, etc.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed additive for aquatic animals and its application. Background technique [0002] Higher fatty alcohols (CnH 2n+1 OH), also known as high-carbon alcohol, refers to a monohydric fatty alcohol with more than six carbon atoms, which is an important raw material for the production of surfactants and plasticizers, and is widely used in medicine, cosmetics, coatings, pesticides, detergents , synthetic fibers and other products (Zhao Fei et al., 1998; Chen Miao et al., 2010). In addition, high-carbon alcohols can also be used as feed additives in the production of livestock, poultry and aquatic animals. Since the 1970s, Japan has conducted research on high-carbon alcohols as fish and shrimp feed additives, and domestic research on high-carbon alcohols as aquatic animal feed additives began in the 1980s. Studies have shown that adding high-carbon alcohols to feed can increase the gr...
