Embodiment 1

[0035] In vitro simulation of the intestinal digestive system of broilers to study the effect of omaibao on the degradation of whole wheat bran

[0036] Taking no enzyme as the blank control group, taking the above-mentioned wheat-specific enzyme preparation and an imported enzyme (HTM) as the experimental group, and taking the relative viscosity as the measurement index, the comparison between the groups was carried out.

[0037] The reaction process is as follows:

[0038]Weigh an appropriate amount of wheat flour into a 50ml conical flask, add pH 3.0 buffer to the substrate according to the relationship of the solid-to-liquid ratio of 1:10, fully stir and infiltrate evenly, and preheat in a 40°C water bath for 5 minutes. While stirring, quickly add 1ml of preheated (5min) appropriately diluted enzyme solution (use enzyme diluent instead of enzyme solution as blank control group), put it into a 40°C constant temperature water bath for digestion, and continuously shake (120r / ...

Embodiment 2

[0044] Validation of feeding effect of broilers

[0045] A total of 560 healthy 1-day-old AA broilers were selected and randomly divided into 4 treatment groups, each treatment had 4 replicates, and each replicate had 20 chickens. The positive control group was fed a corn-soybean meal basal diet; the negative control group was fed a wheat-based basal diet. The feeding and management were carried out according to the routine procedures of commercial chicken farms.

[0046] The experimental design scheme is shown in Table 2:

[0048]

[0049] The composition and nutrient levels of the experimental diets are shown in Table 3 below:

[0052]

[0053] According to the design scheme, the above-mentioned wheat-specific enzyme preparation in the present invention is added to the wheat-based basic diet and mixed evenly, and is used as a powdered feed or as a pelleted feed.

[0054] The test results are as follows:

Embodiment 3

[0070] Example 3 Feeding test of broilers (large group)

[0071] The test was carried out in a broiler farm, 1-day-old broilers were selected, and 8 chicken houses were equally divided into 2 groups, with 4 chicken houses in each group (house 1# house 3# house 5# house 7# house was the experimental group; house 2# house 4 #She6#She8#She is the control group), the control group is the wheat-based basal diet + imported enzyme (DMS), and the addition amount is 500g / t full-price feed; the experimental group is the wheat-based basal diet + oatmeal Treasure, the addition amount is 100g / t full-price material, and the test group increases the cost by 0.5 yuan per ton of material. Feeding and management were carried out according to the routine procedures of commercial chicken farms, and the experimental period was 42 days.

[0072] The experimental design is as follows, see Table 8

Abstract

The invention discloses a complex enzyme preparation special for wheat-based diets. The complex enzyme preparation is characterized by being prepared from a carrier, xylanase, cellulase, amylase, alpha-galactosidase and beta-mannase. In each gram of the complex enzyme preparation, the activity of xylanase is 1000-50000 U/g, the activity of cellulase is 300-3000 U/g, the activity of amylase is 200-1500 U/g, the activity of alpha-galactosidase is 20-200 U/g and the activity of beta-mannase is 200-2500 U/g. According to application of the complex enzyme preparation special for wheat-based diets in poultry feed, 100-300 g of the complex enzyme preparation is added in each ton of the poultry feed. The complex enzyme preparation can effectively degrade soluble xylan and other antinutritional factors, lower the chyme viscosity of the intestinal tract, increase feed metabolic energy, promote nutrition digestion and absorption of animals, improve the growth performance of animals, lower feed cost and increase economic benefits.

Description

technical field [0001] The invention relates to a special compound enzyme for wheat ration and its application in poultry ration. Background technique [0002] With the gradual scarcity of corn grain sources, rising prices, and the widening of the price gap between corn and wheat, the situation that domestic and foreign feed companies use wheat to replace corn is also gradually expanding. At present, the proportion of wheat replacement by some small-scale pig feed manufacturers in China has increased to 30-40%. %, the proportion of wheat substitution in some enterprises producing chicken feed has been expanded to more than 50%, and almost all enterprises producing duck feed use wheat substitution. [0003] Compared with corn, wheat, as a raw material for livestock and poultry feed, has higher nutritional value, higher protein and amino acid content, and slightly lower energy. The high content of anti-nutritional factors in wheat has become the main factor restricting the lar...
