[0002] Under high temperature conditions in summer, dairy cows are easily affected by heat stress, which leads to a decrease in milk production, thus causing a significant decline in the economic benefits of dairy farming. In order to alleviate the effects of heat stress on dairy cows, feed additives are usually added to the feed to regulate the physiological performance of dairy cows. However, there is little research on existing feed additives for heat stress conditions. In actual applications, the effect of alleviating the effects of heat stress on dairy cows is relatively general. In the hot summer, the milk production of dairy cows will still decrease significantly, and the economic benefits will be seriously damaged. Therefore, there is still room for improvement.

[0094] Lactobacillus delbrueckii was purchased from Hubei Mingtuo Biotechnology Co., Ltd. with a viable count of 10 billion cfu / g.
[0095] Experiment 1 The experimental site was a dairy farm in Guangdong. In summer, the highest temperature during the experiment was 35-37℃, and the lowest temperature was 26-28℃.
[0096] 120 healthy Holstein cows were selected from the same cowshed. Their production was tested for 2 consecutive days before the experiment. The cows were divided into 12 groups according to the similar lactation days and production.
[0097] The cows were tethered, fed three times a day, milked three times a day, and provided with fans, sprinklers, and free access to water. The composition, dosage, and feeding method of the diets were the same in each experimental group.
[0098] The daily diet formula is as follows: 9kg of concentrated feed, 1kg of DDGS, 1kg of cottonseed, 5kg of brewer's grains, 2.5kg of beet pulp, 13kg of silage corn, 2kg of alfalfa, and 3kg of wild hay.
[0099] The composite premixes that are beneficial to relieving the heat stress reaction of dairy cows of each embodiment and comparative example are added to the diet of each group of dairy cows respectively. 1.5 kg of the composite premixes that are beneficial to relieving the heat stress reaction of dairy cows are added to each ton of dairy cow diets. The composite premixes that are beneficial to relieving the heat stress reaction of dairy cows are added to the diet and stirred evenly. The composite premixes that are beneficial to relieving the heat stress reaction of dairy cows are prepared with the diet every day, and the composite premixes that are beneficial to relieving the heat stress reaction of dairy cows are added separately to each diet to ensure that the intake of the diet of each dairy cow and the composite premixes that are beneficial to relieving the heat stress reaction of dairy cows are consistent.
[0100] During the experiment, the average daily milk production of each cycle was calculated with each 10-day period as one cycle. The calculation formula was the total milk production of 10 cows in one cycle ÷ 100.
[0101] The trial lasted three cycles totaling 30 days.
[0102] Calculate and record the average lactation days of each group of dairy cows.
[0103] The specific test data of Experiment 1 are shown in Table 1.
[0104] According to the data comparison of each embodiment and the comparative example in Table 1, it can be obtained that the average lactation days of each embodiment and the comparative example are similar, and the average daily milk production in the first cycle is similar. Moreover, the average daily milk production in the second cycle and the average daily milk production in the third cycle of each embodiment are significantly improved, while the average daily milk production in the second cycle and the average daily milk production in the third cycle of each comparative example are only slightly improved, and the increase is significantly lower than that of each embodiment. The dairy cows in each embodiment and the comparative example have passed the peak lactation period, and their daily milk production will not increase over time under normal circumstances, but will gradually decrease over time.
[0105] The main reason for the increase in milk production in the embodiments and comparative examples is that the high temperature causes heat stress in dairy cows, resulting in a decrease in milk production. By taking the composite premix of the embodiments and comparative examples that is beneficial to alleviating the heat stress reaction of dairy cows, the heat stress reaction can be alleviated, so that the milk production can be restored.
[0106] Therefore, according to the data in Table 1, the milk production recovery effect of each embodiment is significantly higher than that of each comparative example, that is, the composite premix that is beneficial to alleviating the heat stress reaction of dairy cows in each embodiment can more significantly alleviate the heat stress reaction of dairy cows, so that dairy cows can maintain a high milk production even at high temperatures, and have higher economic benefits.
[0107] In Comparative Examples 1-5, purple cabbage extract, mangosteen extract, sophora japonica extract, and ophiopogon japonicus extract are replaced by other plant extracts alone or in whole. Although they can also alleviate the heat stress reaction of dairy cows, the effect is significantly reduced compared with the various embodiments. It can be seen that only when purple cabbage extract, mangosteen extract, sophora japonica extract, and ophiopogon japonicus extract are compounded can they exert a significant synergistic effect and have a significant effect of alleviating the heat stress reaction of dairy cows.
[0108] In comparative examples 6-9, Lactobacillus reuteri, Propionibacterium freudenreichii, and Lactobacillus bukesi were replaced by other probiotics alone or in whole, resulting in a decrease in the recovery effect of milk production in dairy cows. It can be seen that when Lactobacillus reuteri, Propionibacterium freudenreichii, and Lactobacillus bukesi are compounded, they can better regulate the gastrointestinal tract of dairy cows, achieve better nutrient absorption, and improve the effect of the composite plant extract in alleviating the heat stress response of dairy cows.
[0109] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
