Tests were conducted on days 1, 14, and 28 for milk sample collection and milk was analyzed for milk protein amount and lactose, and the results are shown in Table 3.
TABLE 3
Besides affecting milk yield, heat stress can also reduce lactose, milk protein, etc. in milk, and affect the quality of milk. As can be seen from Table 3, at the beginning of the experiment, the difference between the milk protein content and the lactose content in the milk produced by the cows in the control group and the experimental group is not large, even the milk protein content and the lactose content in the milk produced by the cows in the experimental group are still lower than those in the control group, but the milk protein content and the lactose content in the milk produced by the cows in the experimental group rapidly rise with the passage of time and are obviously higher than those in the control group. And it can also be seen that the examples of the present application, especially in the preferred case of the present invention, e.g. preferred amounts, preferred rumen bypass amino acids, preferred yeast, have a greater increase in milk protein content and lactose than the products prepared in the comparative examples. This is possible because the test group products slow down the occurrence of heat stress and promote the conversion and absorption of feed nutrients in the dairy cows.
In addition, it can be seen that the experimental group fed with 500 g/day rumen bypass soybean meal and the experimental group fed with 100 g/day rumen bypass amino acid have little influence on the milk yield and the content of milk components of the dairy cows. Therefore, the experimental group using rumen bypass amino acids was able to obtain comparable effects with a smaller feeding amount.
The preferred embodiments of the present invention have been described above in detail, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention, including combinations of various technical features in any other suitable way, and these simple modifications and combinations should also be regarded as the disclosure of the invention, and all fall within the scope of the invention.
