The foregoing is a summary of the present invention, and in order to provide a clear understanding of the technical means of the present invention and to be implemented in accordance with the present specification, the following is a preferred embodiment of the present invention and is described in detail below. Specific embodiments of the present invention are given by the following examples and their details.
Detailed Description
The principles and features of this invention are described below in conjunction with embodiments, which are included to explain the invention and not to limit the scope of the invention.
Example 1
A laying hen feed containing fermented brewer's grains comprises the following raw material components in a formula shown in a table 1:
TABLE 1 example 1 feed formula for laying hens
The layer feed prepared according to the formula is marked as a treatment group; and (3) preparing the laying hen feed by using the same amount of the sprayed corn bran instead of the fermented brewer grains according to the formula, and marking as a control group. And (5) carrying out a comparative test of the influence of the two groups of layer feed on the production performance of the layer.
(1) Design of animal experiment
1920 harland brown laying hens aged 34 weeks were selected and randomly divided into 2 groups of 4 groups of 240 chickens per group, with the initial laying rate of the test laying hens being 92.1%. The experimental pre-feeding period is 1 week, the positive feeding period is 4 weeks, the laying hens freely feed and drink water, and the light intensity is 16 hours and the darkness is 8 hours every day.
(2) Laying hen productivity
Taking the group as a unit, recording the feed intake, egg weight and egg laying number of the laying hens every day, and counting the residual feed amount every week. And calculating the average feed intake, average laying rate, average egg weight and feed-egg ratio of the laying hens every two weeks by taking the groups as units. The production performance data of the layers are shown in table 2. During the test period of 1-2 weeks, the egg weight of the laying hens in the treatment group is obviously increased, and the feed-egg ratio is obviously reduced.
TABLE 2 egg-laying hen production Performance
Note: the difference of the shoulder mark letters of the same row data represents significant difference (P < 0.05); the same row data without shoulder-marked letters or with the same shoulder-marked letters indicate no significant difference (P < 0.05), the same below.
(3) Detecting serum immune globulin and endotoxin of laying hen
After the experiment, 2 laying hens are randomly selected by each group, blood is collected from the wing veins, the blood is centrifuged at low temperature, and upper serum is taken and stored at low temperature for later use. And respectively detecting the content of IgA, igG, igM and ET in the serum by using an enzyme-linked immunosorbent assay. Data on serum immunoglobulin (IgA, igM, igG) and Endotoxin (ET) levels in layers are shown in table 3. The serum IgG content of the laying hens in the treated group is obviously higher than that of the control group, and the ET content is slightly lower than that of the control group.
TABLE 3 detection results of serum immunoglobulin and endotoxin of layer chicken
(4) Detection of chicken intestinal digestive enzyme activity
Randomly selecting 2 laying hens for each group, slaughtering, putting duodenal chyme into a freezing storage tube, quickly freezing in liquid nitrogen, and transferring to a-80 ℃ ultra-low temperature refrigerator for storage for later use. During detection, the chyme is taken out of a refrigerator at the temperature of-80 ℃, unfreezed on ice, and then centrifuged at the temperature of 4 ℃ to obtain supernatant, wherein the supernatant is used for detecting activities of chyme alpha-amylase, lipase and chymotrypsin. The activity data of the duodenal chyme digestive enzyme of the laying hens are shown in a table 4. The activities of alpha-amylase and lipase in duodenal chyme of the laying hens in the treatment group are obviously higher than those of the control group, and the chymotrypsin is slightly higher than that of the control group.
TABLE 4 detection results of intestinal digestive enzyme activity of egg-laying hens
As can be seen by comparing the control group test with the treatment group test, the immunity of the laying hens fed by the laying hen feed is improved, the intestinal digestion capability of the laying hens is improved, the weight of produced eggs is remarkably increased, and the feed-egg ratio is reduced.
Examples 2 to 4

The laying performance of the laying hens in examples 2-4 is shown in table 5, and during the period of 1-2 weeks of the test, the egg weight of the laying hens in the treatment group is obviously increased, the feed-egg ratio is obviously reduced, but the feed-egg ratio is slightly higher than that of the laying hens in example 1.
TABLE 5 egg hen production Performance of examples 2-4
In examples 2-4, the serum immunoglobulin (IgA, igM, igG) and Endotoxin (ET) levels of the layers are shown in table 6, the IgG content in the layer serum of the treated group is significantly higher than that in the control group, the ET content is slightly lower than that in the control group, and the immunoglobulin level in the layer serum is slightly lower than that in example 1.
TABLE 6 EXAMPLES 2-4 detection results of serum immunoglobulin and endotoxin of egg-laying hens
The activity data of the chicken duodenal chyme digestive enzymes in examples 2 to 4 are shown in Table 7. In examples 2-4, the activities of alpha-amylase, lipase and chymotrypsin in duodenal chyme of the laying hens are slightly higher than those of a control group, and compared with the activity levels of the alpha-amylase, the lipase and the chymotrypsin in the laying hens in example 1, the activities of the alpha-amylase, the lipase and the chymotrypsin are slightly lower.
TABLE 7 EXAMPLE 2-4 detection results of intestinal digestive enzyme Activity in egg-laying hens
