Embodiment 1

[0015] Weigh 200g of phytase, 80g of β-glucanase, 100g of xylanase, 120g of β-mannanase, 100g of amylase, and 200g of citric acid and add them to the liquid storage tank of the liquid addition system in conventional production and mix Uniform; in the process of secondary mixing of 2 tons of feed material, the liquid mixed with enzyme preparation is evenly sprayed into the material, and the mixing time is extended for 20 seconds; the material after the secondary mixing is fermented in the silo to be granulated 30 minutes, the fermentation temperature is 40°C, and then enter the normal granulation process.

[0016] The heterogeneous gibel carp with an initial weight of about 150 g was cultured, and the compound feeds treated with and without the enzyme treatment method described in this example were fed respectively. After a 150-day growth experiment, it was found that the growth rate of heterogeneous gibel crucian carp treated with the enzyme increased by 13%; the excrement of ...

Embodiment 2

[0018] Weigh 400g of phytase, 150g of β-glucanase, 250g of xylanase, 150g of β-mannanase, 100g of amylase, and 200g of citric acid into the liquid storage tank of the liquid addition system and mix evenly; After batching, primary mixing and ultra-fine grinding, the feed material per ton is sprayed evenly into the material when it enters the secondary mixer, and the mixing time is extended for 30 seconds; the material after secondary mixing is ready for granulation Ferment in the warehouse for 45 minutes, the fermentation temperature is 37°C, and then enter the normal granulation process.

[0019] The heterogeneous gibel carp with an initial weight of about 150 g was cultured, and the compound feeds treated with and without the enzyme treatment method described in this example were fed respectively. After a 150-day growth experiment, it was found that the growth rate of heterogeneous gibel crucian carp treated with the enzyme increased by 15%; the excrement of the fish was take...

Embodiment 3

[0021] Weigh phytase 100g, β-glucanase 40g, xylanase 50g, β-mannanase 60g, amylase 50g, citric acid 100g and add the liquid storage tank of the liquid addition system and mix evenly; In the process of secondary mixing of tons of feed material, the liquid mixed with the enzyme preparation was evenly sprayed into the material, and the mixing time was extended for 40 seconds; the material after the secondary mixing was fermented in the granulation bin for 50 minutes, and the fermentation The temperature is 40°C, and then enters the normal granulation process.

[0022] The heterogeneous gibel carp with an initial weight of about 150 g was cultured, and the compound feeds treated with and without the enzyme treatment method described in this example were fed respectively. After a 150-day growth experiment, it was found that the growth rate of heterogeneous gibel crucian carp treated with the enzyme increased by 16%; the excrement of the fish was taken by extrusion method for digest...

Abstract

The invention discloses an on-line enzyme treatment method for improving the utilization ratio of a carassius aurutus gibelio feed. The method comprises the following steps of: a, adding an enzyme preparation into a liquid storage tank of a liquid adding system during feed production according to an adding amount and uniformly mixing; b, uniformly spraying the liquid in which the enzyme preparation is mixed into a material in the secondary mixing process of feed processing, and prolonging mixing time by 20 to 30 seconds to guarantee uniform mixing; and c, fermenting the secondarily mixed material in a granulation cabin at the temperature of between 30 and 40 DEG C for 30 to 50 minutes, and entering a normal granulation process. By the method, the damage of super-fine pulverization and high-temperature granulation to enzymatic activity can be avoided, the enzyme preparation can preferably exert effects, the utilization ratio of protein, carbohydrate and mineral elements in the carassius aurutus gibelio feed can be obviously improved, and the enzyme preparation has a stable raw material source and a simple production process.

Description

technical field [0001] The invention relates to an online enzyme treatment method, in particular to an online enzyme treatment method capable of improving the utilization rate of heterogeneous gibel carp feed, and belongs to the field of heterogeneous gibel carp feed processing. Background technique [0002] Allogenetic gibel crucian carp is a new breeding object for crucian carp successfully developed by fish breeding experts from the Institute of Hydrobiology, Chinese Academy of Sciences from 1976 to 1981. As the male parent, the offspring bred by artificial insemination. Allogenetic gibel carp has the characteristics of fast growth, large individual, strong stress resistance, etc. It shows good economic characteristics in aquaculture production, and is currently widely aquaculture in Jiangsu and other places in my country. There have been many studies on compound feeds for heterogeneous gibel carp, such as Chinese patents CN02115491.0, CN02115492.9 and 200610038034.5. H...
