Problems solved by technology

There are few domestic reports on the requirements of trace elements and vitamins in the premixed feeds of long-snout catfish. Most of the feeds used are conventional premixed feeds for fish. In traditional feed farming, the growth rate of fish is slow, the scale of farming is limited, and diseases occur from time to time.

preparation example Construction

[0034] In the long-snout catfish composite premix, the vitamin carrier is defatted rice bran, and the mineral diluent is limestone powder. The preparation method of long snout composite premix, it may further comprise the steps:

[0035] 1) Preparation of raw materials: Prepare various raw materials according to the ingredients and proportions of the above formula, and it is best to choose dry carriers, diluents or premixes. The diluent should choose a material with poor water absorption, good fluidity, and no need to dry. The carrier selected in this premix is ​​defatted rice bran with a particle size of 60 mesh. The diluent is limestone powder with a particle size of 100 mesh. If the diluent is wet, it must be through the next process;

[0036] 2) Pretreatment of raw materials: dehydration, drying and pulverization of raw materials, pulverization of carriers or diluents, pulverization of major elements and fine pulverization of trace elements, micro-material MgSO with stron...

Embodiment 1

[0038] Embodiment 1: long-snout catfish composite premix, including additive A containing multivitamins and additive B containing multiminerals, wherein:

[0039] 1) Proportion and preparation of additive A containing multivitamins per kilogram: according to V A :4500 IU, V D : 1500IU, V E : 1.3g, V K : 0.08g, V B1 : 0.05 g, V B2 : 0.10g, V B6 : 0.05g, calcium pantothenate: 0.10g, niacinamide: 0.26g, folic acid: 0.05g, V C : 5.2g, choline chloride 4g, inositol ： 0.75g, and the rest is defatted rice bran; the sum of the weight of each of the above components plus the weight of defatted rice bran is 1 kg.

[0040] Preparation:

[0041] 1) Preparation of raw materials: Prepare various raw materials according to the ingredients and proportions of the above formula. The carrier selected in this premix is ​​defatted rice bran with a particle size of 60 mesh;

[0042] 2) Pretreatment of raw materials: the raw materials are dehydrated, dried and crushed, the carrier is cr...

Abstract

The invention discloses a composite premix for leiocassis longirostris and a preparation method for the composite premix. The composite premix consists of multiple vitamins and multiple mineral substances. Each kilogram of premix comprises the following vitamin raw materials: 4,500 IU of VA, 1,500 IU of VD, 1.3 g of VE, 0.08 g of VK, 0.05 g of VB1, 0.10 g of VB2, 0.08 g of VB6, 0.10 g of calcium pantothenate, 0.26 g of nicotinamide, 0.05 g of folic acid, 5.2 g of VC, 4 g of choline chloride, 0.75 g of inositol, and the balance of defatted rice bran; and each kilogram of premix comprises the following mineral substance raw materials: 14 g of Na2HPO4, 40 g of CaCO3, 0.60 g of KCl, 2.0 g of MgSO4, 5.0 g of ferric citrate, 0.10 g of ZnSO4, 0.01 g of CuSO4, 0.004 g of KI, 0.001 g of CoCl2, 0.02 g of MnSO4, and the balance of limestone powder. The composite premix is suitable for artificial breeding of the leiocassis longirostris, and has high bait utilization rate.

Description

technical field [0001] The invention relates to a feed additive, in particular to a long-snout catfish compound premix and a preparation method thereof. Background technique [0002] Commonly known as Jiang Tuan and Fatuo, long-snout catfish belongs to Siluriformes, Osmanthidae, and Catfish genus. It is distributed in the Liaohe River, Huaihe River, Yangtze River, Minjiang River to Pearl River and other water systems in my country. It is an important economic fish in China. The meat of long-nosed squid is tender, delicious, and has no spines. It is known as the top-grade freshwater edible fish. Its swim bladder is thick and dried. It is also a rare delicacy. In recent years, due to various reasons, the resource of long-snout catfish in the Yangtze River has decreased sharply, and the market is in short supply. Therefore, artificial breeding of long-snout catfish has begun to rise across the country. [0003] Long-snout catfish grows fast, and the largest individual in the ...
