Embodiment 1

[0034] Example 1 Hull Barley Component Determination

[0035] Table 1 Determination results of husk barley components

[0036] project

[0037] Arginine, %

[0038] It can be seen from the analysis and detection indicators that the crude protein content of husk barley is higher than that of corn, the available phosphorus content is low, and the true amino acid digestibility of poultry is relatively low (about 80.0%), which is more than 5% lower than that of corn. In addition, the AME values ​​for poultry are lower than for corn. The content of anti-nutritional factors β-glucan and arabinoxylan is high.

Embodiment 2

[0040] Produce 1 ton of yellow-feathered broiler feed formula as following table 2:

[0041] Table 2 Whole Hull Barley Type Feed Formula

[0042]

[0043]

[0044]The premix contains barley-hulled special compound enzyme (250g / ton), including β-glucanase 4000u / g, arabinoxylanase 20000u / g, cellulase 400u / g, phytase 8000u / g , Neutral protease 500u / g, alkaline protease 1000u / g, pectinase 800u / g.

[0045] The preparation method of the whole barley type feed is completed according to the following process steps:

[0046] A. After the raw materials such as barley husk, soybean meal, and corn gluten powder of each weight in Table 2 are removed from impurities, they are pulverized to powder respectively with a pulverizer of 2.5mm sieve.

[0047] B. Then put the pulverized raw materials into the mixer to mix and stir evenly, then mix the lysine, methionine, threonine, sodium bicarbonate, salt, premix, stone powder, calcium hydrogen phosphate After the second premixing, the spe...

Embodiment 3

[0052] The experimental diet formula is as follows in Table 3:

[0053] table 3

[0054]

[0055] Among them, the yellow feather broiler chickens in the control group and the yellow feather broiler chickens in the test group had exactly the same nutritional level of the corresponding diets. They were fed the same feed for 1 to 21 days, and their average weight was 420g. The experiment officially started from the age of 22 days.

[0056] Produce feed according to the feed processing procedure in the above diet formula and example 2, then carry out high-quality chicken feeding test, test is divided into three treatment groups, each handles 6 repetitions, each repeats 75 chickens. The following trials were carried out in summer and no negative effects were observed from the use of hulled barley under conditions of heat stress.

[0057] Control group: feed A1 on 22-43 days, feed A2 on 43-63 days;

[0058] Hulled barley without enzyme group: feed B1 on 22-42 days, and B2 on 43...

Abstract

The invention discloses a specific compound enzyme for husk barley and a full-husk barley-type feed and a preparation method thereof. The compound enzyme includes beta-glucanase, arabinoxylanase, cellulase, phytase, neutral protease, alkali protease and pectinase. The full-husk barley-type feed includes the ingredients of full-husk barley, whole-fat extruded soybean, soybean meal, cottonseed protein, corn protein, soybean oil, calcium hydrogen phosphate, stone flour, lysine, methionine, threonine, sodium chloride, sodium bicarbonate, and a premix containing the above compound enzyme and a pigment. By adding the specific compound enzyme for husk barley, the anti-nutritional factors in the full-husk is eliminated, and combination of a variety of materials solves the problem of imbalance between energy value and arginine of the husk barley. The husk barley can be uses as the main feed ingredient to completely replace high quality chicken feed such as corn, and is very applicable to the high-quality chickens resistant to crude feed in large and middle stages.

Description

technical field [0001] The invention belongs to the technical field of poultry feed, and in particular relates to a special compound enzyme for husk barley, whole-hull barley feed and a preparation method thereof. Background technique [0002] With the rapid development of animal husbandry in my country, the supply of feed resources in China is tight. In 2014, the total import of soybean meal in my country was more than 60 million tons. At the same time, a large amount of energy feed such as corn and sorghum is also imported every year. At present, the prices of corn and soybean meal have been at a high level. The development of new feed resources is conducive to reducing costs and meeting the needs of sustainable and healthy development of my country's aquaculture industry. At present, the amount of high-quality chickens slaughtered in my country accounts for about half of the total broiler chickens slaughtered in my country. The feed conversion efficiency of high-quality...
