Problems solved by technology

[0003] Largemouth bass has a high degree of sugar intolerance. The starch content in the feed for this fish on the market is more than 10%, but some studies have shown that the optimum starch content in the feed for largemouth bass is less than 10%. The accumulation of glycogen and fat in the liver of largemouth bass will damage the liver function, thereby affecting the growth of largemouth bass, reducing the survival rate and increasing the cost of breeding

preparation example Construction

[0038] The method for preparing the low-sugar compound feed for largemouth bass includes weighing, crushing, sieving, mixing uniformly and making granules according to the aforementioned composition to obtain the low-sugar compound feed for largemouth bass.

[0039] Preferably, in the preparation method, the sieving is through a 50-mesh sieve; further preferably, the sieving is through a 60-mesh sieve.

[0040] Preferably, in the preparation method, the produced particles have a diameter of 2 mm and a length of 5 mm to 10 mm.

[0041] Further, the preparation method of this low-sugar compound feed for largemouth bass is to weigh according to the above-mentioned composition, go through superfine grinding, pass through a 60-mesh sieve, mix evenly according to the method of step-by-step expansion, then add oil and mix evenly, and use the puffing mechanism to mix evenly. into pellets with a diameter of 2 mm and a length of 5 to 10 mm to obtain a low-sugar compound feed for largemo...

Embodiment 1

[0055] Granular largemouth bass compound feed was prepared according to the raw material formula of the comparative example in Table 1. The individual feed was ultrafinely pulverized, passed through a 60-mesh sieve, mixed evenly according to the step-by-step expansion method, and then added oil and mixed evenly, and made into a large-mouth bass with an extruder. 2mm particles with a length of 5-10mm. Wherein, the multivitamin described in the comparative example is composed of the following components in mass percentage: 80.0 parts of vitamin A, 1.2 parts of vitamin C, 16.0 parts of vitamin D3, 30.1 parts of vitamin K, 0.6 parts of vitamin E, 0.1 part of vitamin B1, and 0.1 part of vitamin B2 0.3 parts, vitamin B6 0.2 parts, vitamin B12 0.2-0.3 parts, folic acid 0.1 parts, calcium pantothenate 0.3 parts, biotin 0.1 parts, niacinamide 0.4 parts, inositol 0.8 parts. Composite mineral salt described in the comparative example is made up of the composition of following mass percen...

Embodiment 2

[0063] Granular largemouth bass compound feed was prepared with the raw material formula of Example 2 in Table 1. The single feed was ultrafinely pulverized, passed through a 60-mesh sieve, mixed uniformly according to the step-by-step expansion method, then added oil and mixed evenly, and then mixed evenly with an extruding mechanism. Particles with a diameter of 2 mm and a length of 5-10 mm, the multivitamins used in Example 2 are made up of the following mass percentages: 80.0 parts of vitamin A, 1.2 parts of vitamin C, 16.0 parts of vitamin D3, 0.1 parts of vitamin K, and 0.6 parts of vitamin E 0.1 part of vitamin B1, 0.3 part of vitamin B2, 0.2 part of vitamin B6, 0.2-0.3 part of vitamin B12, 0.1 part of folic acid, 0.3 part of calcium pantothenate, 0.1 part of biotin, 0.4 part of niacinamide, and 0.8 part of inositol. The used compound mineral salt of embodiment 2 is made up of the composition of following mass percent: ZnSO 4 ·7H 2 O 71.3 parts, MnSO 4 ·H 2 O 4.9 par...

Abstract

The present invention discloses a low-sugar compound feed for micropterus salmoides and a preparation method thereof. The low-sugar compound feed for the micropterus salmoides is composed of the following raw materials: protein source raw materials, sugar source raw materials, a filler, an antioxidant, multivitamins, compound mineral salts, a feed additive and fat raw materials. At the same time,the preparation method of the low-sugar compound feed for the micropterus salmoides is also disclosed. The preparation method explores the optimum starch addition amount. The low-sugar compound feed for the micropterus salmoides improves the growth rate and reduces the mortality of the micropterus salmoides body, at the same time improves immunity of the micropterus salmoides body, reduces damageof the liver, and is obvious in effect and superior to existing commercial feeds.

Description

technical field [0001] The invention relates to a low-sugar compound feed for largemouth bass and a preparation method thereof, belonging to the technical field of feed. Background technique [0002] Largemouth bass (Micropterus salmoides, commonly known as California perch), belongs to Perciforme (Perciforme), sunfish family (Ceutrarchidac), and black bass (Micropterus). The largemouth bass is a carnivorous warm-water fish native to the Mississippi River system in California, USA. At the end of the 1970s, the Taiwan region of my country introduced largemouth bass from abroad. In 1983, artificial breeding was successful, and in the same year it was introduced from Taiwan to Guangdong Province of my country. Due to the characteristics of rapid growth, strong disease resistance, wide temperature adaptability, and delicious meat, largemouth bass has been promoted all over the country and has become one of the important freshwater aquaculture species in China. [0003] Largemo...
