Embodiment 1

[0052] Example 1 Preparation of sawdust

[0053] The preparation method of sawdust comprises the following steps: removing foreign matter from sawdust or waste sawdust without mildew and pests, placing it in an ultrasonic cleaner at 200W, 30KHz for 10 minutes, rinsing and draining, putting it into a steam kettle at 0.35 Cook at MPa for 25 minutes, then place it in a microwave dryer at 2000W and 120°C for 3 minutes for intermittent drying, so that the water content reaches 9%, and finally 2.0 sieves are crushed, sealed and packaged to obtain wood chips;

[0054] The cleaning solution is a sodium bicarbonate solution with a mass percent concentration of 0.5%;

[0055] The batch drying process is as follows: microwave radiation for 10s, stay for 10s, and so on, and cycle drying.

Embodiment 2

[0056] The preparation of embodiment 2 probiotics

[0057] The preparation method of the microecological preparation comprises the following steps: Bacillus subtilis CGMCC NO.7926 and Lactobacillus plantarum CGMCC NO.7928 are respectively activated by slant strains and first-level, second-level, third-level liquid seeds and first-level seed tanks are respectively The liquid seeds were obtained by the expansion of the first stage, and then uniformly mixed in a volume ratio of 2:4, inserted into the secondary seed tank with 10% inoculum, and cultivated at 35°C for 20h to obtain the mixed liquid seeds. The stirring speed was 500r / m, and the ventilation rate (V / V ) 1:2; put the mixed liquid seeds into the fermenter with 6% inoculum size, culture at 33°C for 12h, stirring speed 400rpm, ventilation volume (V / V) 1:3, and then slowly cool down to 2°C / h cooling rate to 12°C, constant temperature culture for 15-20h; continue to slowly cool down to 4°C at a cooling rate of 2°C / h. h The ...

Embodiment 3

[0071] A method for preparing a composite premix during laying period, comprising the following steps: the composite premix is ​​composed of the following raw materials in parts by weight: 40 parts of sawdust, 20 parts of calcium hydrogen phosphate, 20 parts of zeolite powder, rapeseed meal 11.34 parts, 6.5 parts of salt, 5 parts of gastric acid, 3.3 parts of DL-methionine, 3 parts of compound trace elements, 2 parts of Sumexazol, 1 part of compound enzyme preparation, 1.8 parts of probiotics, 1.2 parts of choline chloride, compound 0.6 parts of vitamins, 0.5 parts of Hemeisu, 0.6 parts of 30 betaine, 0.12 parts of Xianling No. 5 powder;

[0072] Described sawdust is prepared for embodiment 1;

[0073] Described probiotics preparation is embodiment 2;

[0074] Preparation method: First, crush the rapeseed meal with a 2.0 sieve for later use, then uniformly mix the sawdust and zeolite powder, and finally take the material in sequence according to the above raw material formula, ...

Abstract

The invention discloses a preparation method for a compound premix in an egg producing period, belonging to the technical field of feed compositions. Anti-nutritional factors are removed from soybean meal through a compound enzyme preparation containing beta-mannase, beta-dextranase, acid proteinase and phytase, and factors, such as mycotoxin, which is caused by use of a large quantity of corns and affect the intestinal health, can be effectively removed through the yeast cell wall type mycotoxin adsorbent; the pH value of the intestinal tract is effectively adjusted by using stomach invigorating acid. Sawdust prepared by the preparation method disclosed by the invention is soft, is high in cellulose content, and is free from pollution; the intestinal tract does not need to be scraped; the digestion and absorption functions of laying hens can be effectively enhanced, and the bearing function and the water absorption function are high. Due to the scientific application of various comprehensive measure systems, the optimal intestinal tract health states of the laying hens in the egg producing period are guaranteed, the immunity and the disease resistance of the laying hens are enhanced, the maximum laying performance of the laying hens is achieved, the moisture content of excrements is reduced, and the maximum economic benefit of a farm using the premix is obviously improved.

Description

technical field [0001] The invention relates to a feed composition, in particular to a method for preparing a compound premix during laying period. Background technique [0002] Due to the large-scale breeding of laying hens, there are many chicken farms using premix. Compared with full price feed and concentrated feed, premix is ​​the feed with the lowest degree of industrialization. At present, there are many problems in the use of premix, the main problem is manure Diluted, poor gut health. Because when the premix is ​​used to form a complete feed, the amount of soybean meal used is large, the content of anti-nutritional factors in soybean meal is high, and the high content of potassium ions in soybean meal is also a factor that causes high water content in feces; the main anti-nutritional factor in soybean meal is trypsin inhibitor , it will reduce the activity of pancreatic (chymotrypsin), delay growth, and cause pancreatic hyperplasia and swelling; followed by soybean...
