Embodiment 1

[0056] Example 1 Preparation of wood chips

[0057] The preparation method of sawdust includes the following steps: remove the debris from sawdust or waste sawdust without mold, disease and insects, place it in an ultrasonic cleaning machine at 200W, 30KHz for 10 minutes, rinse, drain, and put it in a steam kettle at 0.35 MPa cooking for 25 minutes, then set a microwave dryer at 2000W, 120°C for intermittent drying for 3 minutes to make the moisture reach 9%, and finally the 2.0 sieve pieces are crushed and sealed to obtain sawdust;

[0058] The cleaning solution is a sodium bicarbonate solution with a concentration of 0.5% by mass;

[0059] The intermittent drying process is: microwave radiation for 10s, staying for 10s, repeating this way, and cyclic drying.

Embodiment 2

[0060] Example 2 Preparation of probiotics

[0061] The preparation method of the microecological preparation includes the following steps: Bacillus subtilis CGMCC NO. 7926 and Lactobacillus plantarum CGMCC NO. 7928 are activated by slant strains, and the first, second, and third liquid seeds and the first-class seed tanks are respectively activated. Stage expansion culture to obtain liquid seeds, then evenly mix according to the volume ratio of 2:4, connect to the secondary seed tank with 10% inoculum, cultivate at 35°C for 20 hours to obtain mixed liquid seeds, stirring speed 500r / m, ventilation (V / V )1:2; The mixed liquid seeds are connected to the fermentor at 6% inoculum, cultivated at 33°C for 12h, stirring speed 400rpm, ventilation (V / V) 1:3, and then slowly cooled to 2°C / h Incubate at 12°C for 15-20h at a constant temperature; continue to slowly cool down to 4°C at a cooling rate of 2°C / h. At this time, add the mixed liquid seeds to the fermentor at a 4% inoculum amount, ...

Embodiment 3

[0075] A composite premix for laying hens to improve intestinal health in laying hens, consisting of the following parts by weight of raw materials: 30 parts by weight of sawdust, 20 parts of dicalcium phosphate, 15 parts of zeolite powder, 11.34 parts of rapeseed meal, and 6.5 parts of salt. Servings, 3.2 parts of stomach acid, 3.3 parts of DL-methionine, 3 parts of complex trace elements, 2 parts of mimezone, 1 part of complex enzyme preparation, 1.4 parts of probiotics, 1.2 parts of choline chloride, 0.6 parts of multi-vitamins, Hemei 0.5 part of effect element, 0.6 part of 30 betaine, 0.12 part of Xianling No. 5 powder;

[0076] The sawdust was prepared in Example 1;

[0077] The microecological preparation was prepared in Example 2;

[0078] Preparation method: first crush the rapeseed meal with a 2.0 sieve for use, then mix the sawdust and zeolite powder uniformly, and finally take the material in sequence according to the above-mentioned raw material formula and mix evenly to...

Abstract

The invention discloses a laying period compound premix capable of improving the intestinal health of laying hens, and applications of the laying period compound premix, belonging to the technical field of feed compositions. A compound enzyme preparation containing beta-mannase, beta-glucanase, acid protease and phytase is used for removing antinutritional factors in soybean meal; yeast cell wall type myeotoxin adsorbents are used for effectively removing mycotoxin which is brought by the use of corn in a large dose and influences the intestinal health; and stomach strengthening acid is used for effectively adjusting the pH value of intestines. Wood dust prepared by using the compound premix provided by the invention has the advantages of soft texture, high cellulose content, intestine scratching prevention and pollution-free properties, and is capable of effectively improving the digestion and absorption functions of laying hens, thereby having good performance in bearing and water absorption. Through systemic and scientific application of the above comprehensive measures, the optimum intestinal health of the laying hens in the laying period is ensured; the immunity and the disease-resistant capability of the laying hens are improved; the best laying performance of the laying hens is achieved; the water content of manure is reduced; and the maximum economic benefits of farms using the premix are obviously improved.

Description

Technical field [0001] The invention relates to a feed composition, in particular to a composite premix for laying hens during laying period for improving intestinal health and application thereof. Background technique [0002] Due to the large scale of laying hens, there are more chicken farms using premix. Compared with full-price feed and concentrated feed, premix is ​​the lowest industrialized feed. At present, there are many problems in using premix. The main problem is manure. Dilute, poor intestinal health. Because the amount of soybean meal used when premixed into full-price feed is large, the content of anti-nutritional factors in soybean meal is high, and the high potassium ion content in soybean meal is also a factor that causes high fecal water content; the main anti-nutritional factor in soybean meal is trypsin inhibitor , It will reduce the activity of pancreatic (chymotrypsin) protease, delay growth, and cause pancreatic hyperplasia and enlargement; secondly, soyb...
