Background
In 2011, the egg yield in China reaches 2380 ten thousand tons, which accounts for about 36 percent of the global yield. Currently, the laying hen industry in China is turning to large-scale, intensive and specialized production modes. In the process of laying hen breeding, the industry mainly focuses on the laying rate of laying hens in the peak period, but the length of the laying period (average daily egg production of 55 g/feather) is often ignored, particularly in the peak period of the laying period. Therefore, shortening the time from the laying peak to the egg laying peak of the laying hens not only reduces the feeding cost, but also improves the breeding return, so that the development of a nutrition enhancer for shortening the time from the laying peak to the egg laying peak of the laying hens is very necessary.

According to the formula in example 1, the present embodiment provides a preparation method of a layer nutrition enhancer, specifically including the following steps: weighing the components in parts by weight, sequentially adding the components in a mixer from large to small in parts by weight, uniformly mixing, and subpackaging by using a nontoxic bag to obtain the Chinese medicinal composition.
Example 3
Testing the feeding effect of the layer nutrition enhancer.
According to the formulas in the example 1 and the preparation method in the example 2, 8 groups of layer nutrition enhancers are prepared.
12000 Roman powder laying hens of the same age of the day (16 weeks old and not laid) are selected, and the Roman powder laying hens are designed by adopting a single-factor completely random test and divided into 9 treatment groups, each group comprises 10 repetitions, and each repetition comprises 200 repetitions.
Test groups: the feeding method is to feed the laying hen with the basic complete feed and the layer nutrition enhancer accounting for 0.30 percent of the basic complete feed in a mixed manner.
Control group: the feeding method is a basic complete feed for feeding. The test was carried out on the Shiheji area of ecological food, Inc. of san Dilecura, Sichuan.
TABLE 2 feeding test table for layer chicken nutrition enhancer
Note: the difference of the same row shoulder mark letters indicates that the difference is significant (P < 0.05).
As can be seen from Table 2, each test group has significant differences compared with the control group, which indicates that the addition of the layer nutrition enhancer of the invention to the basic full-value feed can shorten the time from the laying period to the egg laying peak period of the layer.
Example 4
Addition amount test of formulation 5.
According to the formula 5 in the example 1, the layer nutrition enhancer is prepared according to the preparation method in the example 2.
18000 Roman powder laying hens of the same age of day (16 weeks old and not on production) are selected, and the Roman powder laying hens are designed by adopting a single-factor completely random test and divided into 9 treatment groups, each group is 10 repetitions, and each repetition is 200. The addition amount of the layer nutrition enhancer of different groups is different, and a control group is arranged to feed basic complete feed.
Table 3 table of addition amount test results of formulation 5
Note: the difference of the same row shoulder mark letters indicates that the difference is significant (P < 0.05).
As can be seen from Table 3, compared with the control group, the groups from experiment 2 to experiment 9 have significant differences, which indicates that the time from the laying hen laying peak period to the laying hen laying peak period can be shortened by adding 0.15-0.5% of the laying hen nutrition enhancer of the invention into the basic full-value feed. When the addition ratio is less than 0.15% or more than 0.50%, there is no significant difference compared with the control group, indicating that it is not effective in shortening the time taken for the onset to the peak of egg production. As can be seen from Table 3, the addition ratio of the feed additive is 0.30%, the time from the production start to the egg-laying peak period can be effectively shortened, the feed cost is saved, and the cost performance is highest.

Example 6
Feeding effect test of comparative formula
According to the formulas in the example 5 and the preparation method in the example 2, 4 groups of layer nutrition enhancers were prepared.
12000 Roman powder laying hens of the same age of the day (16 weeks old and not laid) are selected, and the Roman powder laying hens are designed by adopting a single-factor completely random test and divided into 9 treatment groups, each group comprises 10 repetitions, and each repetition comprises 200 repetitions.
Test groups: the feeding method is to feed the laying hen with the basic complete feed and the layer nutrition enhancer accounting for 0.3 percent of the basic complete feed in a mixed manner.

Table 5 comparative formula feeding effect test table
Note: the difference of the same row shoulder mark letters indicates that the difference is significant (P < 0.05).
As can be seen from table 5, the group 1 had a significant difference from the control group, and the groups 2 to 5 had no significant difference. Namely, the addition proportion is the same as that of the invention, but the components are different, and the time from the start of laying to the peak period of laying is not good; the addition proportion and the formula components are the same as those of the invention, but the proportion of each component is different, so the time from the production to the egg-laying peak period is shortened, and the effect is not good.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made in the spirit and the concept of the main body of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
