Embodiment 1
[0045] The formula of each part of the feed to be processed is as follows:
[0046] Table 1. The feed formula to be processed that embodiment 1 adopts
[0047]
[0048] Specific process such as figure 2 Shown:
[0049] (1) Part of the granular raw materials, that is, corn kernels and dried yellow algae are mixed according to a weight ratio of 1:1, stirred evenly, and added into the pulverizer at a uniform speed, while feeding and discharging. After pulverization, the initial mixture formed by the dried Xanthophylla and corn kernels is filtered through a sieve with a pore size of 0.1mm, and is pulverized into a powdery mixture;
[0050] (2), with the pulverized powdery mixture, according to the feed formula in Table 1, carry out with the rest in the raw material, namely: remaining corn kernels, soybean meal, premix, bone meal, stone powder, soybean oil and corn protein Mix and stir for 10 minutes. Then granulation is carried out under the steam condition of 70° C. to fo...
Embodiment 2
[0054] The formula of each part of the feed to be processed is as follows:
[0055] Table 2. The feed formula to be processed that embodiment 2 adopts
[0056]
[0057] The specific process can refer to figure 2 , the following embodiments will not be repeated.
[0058] (1) Part of the granular raw materials, that is, corn kernels, and dry Xanthophyllum are mixed in a weight ratio of 2:1, stirred evenly, and added into the pulverizer at a uniform speed, while feeding and discharging. After pulverization, the initial mixture formed by the dried Xanthophylla and corn kernels is filtered through a sieve with a pore size of 0.2mm, and is pulverized into a powder mixture;
[0059] (2), with the pulverized powdery mixture, according to the feed formula in Table 1, carry out with the rest in the raw material, namely: remaining corn kernels, soybean meal, premix, bone meal, stone powder, soybean oil and corn protein Mix and stir for 20 minutes. Then granulation is carried out ...
Embodiment 3
[0063] Divide into three groups to feed laying hens at the same time, and the feeding environment conditions are the same, respectively numbered as group A, group B and group C, and each group has 100 laying hens. Among them, the laying hens of group A were fed with the aforementioned feed a, the laying hens of group B were fed with the aforementioned feed b, and the laying hens of group C were fed with the aforementioned feed c, and the feeding time was 60 days.
[0064] The EPA content in eggs has been tested as follows: Figure 5 As shown, it can be seen that the EPA content in the eggs produced by the laying hens of group A and group C fed with feed a and c is significantly higher than that of group B. Among them, the layer hens in group C were fed with 11% of yellow silk algae in the feed, but the EPA content in eggs was not significantly higher than that of group A layer fed with the layer feed with yellow silk algae content of 7%. Therefore, considering the feed feedin...
