Abstract
Description
Technical Field
[0001] The present application relates to the technical field of feed additives, and in particular to a synbiotic feed additive and a preparation method and application thereof. Background Art
[0002] Feed additives refer to small or trace substances added during feed production and processing or basic feed feeding, which can enhance the nutritional value of basic feed, significantly increase the growth rate of animals, enhance immunity and improve meat quality. As people pay more and more attention to food safety, natural feed additives with no side effects have gradually become a research hotspot.
[0003] Traditional feed additives mainly include antibiotics, hormone drugs and some chemical synthetic substances. Although these additives can achieve good results in the short term, they also have certain safety hazards and side effects, such as drug resistance caused by the abuse of antibiotics and the problem of chemical synthetic substance residues. In recent years, in order to overcome the above problems, researchers have begun to explore the use of natural plant extracts (such as peppermint oil, curcumin, allicin, etc.) and microbial preparations (probiotics) to replace traditional feed additives. However, the existing natural plant extracts and probiotic compound feed additives still have some shortcomings in practical applications. For example, the effect of a single plant extract or probiotic is limited, and it is difficult to meet the diverse breeding needs; in addition, the synergistic mechanism between different ingredients is not clear, and the formula design lacks a scientific basis, resulting in unstable product performance and difficulty in large-scale promotion and application.
[0004] Therefore, developing a new feed additive that can effectively improve animal health, enhance immunity, and have stable performance is an urgent problem to be solved in this field. Summary of the invention
[0005] In order to overcome the problems of limited use effect and unstable product performance of existing feed additives, the present application provides a synbiotic feed additive and a preparation method and application thereof.

[0007] The present application provides a synbiotic feed additive, which can activate the digestion and immune function of the animal intestine, promote the digestion and absorption capacity and immunity of the animal, inhibit the reproduction of harmful bacteria, reduce the occurrence of intestinal diseases, thereby improving the breeding production efficiency and reducing the breeding cost. Specifically, the addition of probiotics can regulate the balance of the intestinal microecology of the animal, inhibit the growth of harmful bacteria, promote the reproduction of beneficial bacteria, and thus improve the intestinal health. Lycopodium powder is rich in dietary fiber and trace elements, which can enhance the appetite and digestive function of animals. On the one hand, green segment grass extract and long pole orchid extract have antioxidant and anti-inflammatory effects, which can reduce inflammatory response, reduce stress response, and improve the overall health level of animals; on the other hand, they contain rich bioactive substances, which can promote the growth and development of animals and improve production performance.

[0058] The preparation method of the beef cattle feed of Example 1-20 is: adding the vitamin feed additive in an amount of 1 g / kg to ordinary beef cattle feed (purchased from Beijing Jiahe Mufeng Feed Co., Ltd.), mixing evenly, and obtaining beef cattle feed. Comparative Application Examples 1-4
[0059] Comparative Application Examples 1-4 each provide a beef cattle feed.
[0060] The difference between the above comparative application example and application example 2 is that the synbiotic feed additive in the beef cattle feed is derived from comparative examples 1-4 respectively. Performance testing 1. Beef cattle feeding experiment
[0061] The beef cattle feeding test was conducted using the beef cattle feed provided in Application Example 1-20 and Comparative Application Example 1-4. The test method is as follows: (1) Experimental animals: 125 Simmental cattle aged 12 months were selected and randomly divided into 25 groups, with 5 cattle in each group; (2) Feeding management: 20 groups were fed with the beef cattle feed provided by Application Examples 1-20; 4 groups were fed with the beef cattle feed provided by Comparative Examples 1-4; 1 group was fed with ordinary feed (as a blank control group); the experimental period was 30 days. During the experimental period, the animals were fed in a single trough twice a day, with free access to food and water, and all conditions were basically the same. (3) Test: Before the experiment, weigh the fasting weight of each cow; during the experiment, record the feed intake of each group of beef cattle in detail every day; after the experiment, weigh the fasting weight of each cow. The average daily weight gain, average daily feed intake and feed-to-meat ratio of each beef cattle were calculated comprehensively, and the results are shown in Table 3 below.
[0062] Average daily weight gain of each cow = (average weight of each group of cows at the end of the test - average initial weight of each group of cows) / 150 Average daily feed intake per cow = 30-day feed consumption per group of cows / 150 Feed-to-meat ratio = average daily feed intake per cow / average daily weight gain per cow.
[0063] Table 3 Test results of beef cattle feeding experiment
[0064] According to the test results in Table 3, the beef cattle feed obtained by Application Example 1-20 and Comparative Application Example 1-4 and commercial beef cattle feed were used for 30 days of beef cattle feeding; the average daily feed intake of beef cattle fed by Application Example 1-20 was 11.7-12.8 kg / head, the average daily weight gain was 1.48-1.84 kg / head, and the feed-to-meat ratio was 6.85-7.99, while the average daily feed intake of beef cattle fed by Comparative Application Example 1-4 and commercially available feed was 8.5-10.5 kg / head, the average daily weight gain was 0.83-1.01 kg / head, and the feed-to-meat ratio was 9.54-10.24. Obviously, the average daily feed intake and average daily weight gain of beef cattle fed by Application Example 1-20 were significantly higher than those of Comparative Application Example 1-4 and commercially available feed cattle, and the feed-to-meat ratio of beef cattle fed by Application Example 1-20 was significantly lower than that of Comparative Application Example 1-4 and commercially available feed cattle. Therefore, it is shown that the synbiotic feed additive provided in the present application can significantly improve the absorption and digestion ability of beef cattle to feed, thereby improving the growth performance and feed conversion rate of beef cattle, increasing the breeding efficiency of farms, and has good economic value and application prospects.
[0065] The test results of Application Examples 1-13 show that the feed-to-meat ratio of beef cattle fed with the beef cattle feed obtained in Application Examples 2-3, Application Examples 6, Application Examples 9, and Application Examples 12 is 7.42-7.64 (≤7.70); while the feed-to-meat ratio of beef cattle fed with the beef cattle feed obtained in Application Examples 1, Application Examples 4-5, Application Examples 7-8, and Application Examples 10-11 is 7.81-7.99 (>7.70). Therefore, it is explained that the application further controls the weight of each plant extract within the following range: 1-1.3 parts of Lycopodium powder, 0.5-0.8 parts of green segment grass extract, 0.5-0.8 parts of long-stem orchid extract, and 0.2-0.3 parts of fir fruit extract, and the use effect of the obtained synbiotic feed additive is better, so that the feed conversion rate of beef cattle is better.
[0066] The test results of Application Examples 2 and 14-20 show that after feeding beef cattle with the beef cattle feed obtained by using Saccharomyces boulardii, Lactobacillus gasseri and Lactobacillus rhamnosus as probiotics in feed additives in Application Example 14-20, the average daily feed intake and average daily weight gain of beef cattle were increased, and the feed-to-meat ratio was decreased; further comparison found that the feed-to-meat ratio of beef cattle fed with the beef cattle feed obtained in Application Example 14-18 was 6.85-6.98 (≤7.00); while the feed-to-meat ratio of beef cattle fed with the beef cattle feed obtained in Application Examples 19-20 was 7.18-7.31 (>7.00). Therefore, it is explained that the present application further uses Saccharomyces boulardii, Lactobacillus gasseri and Lactobacillus rhamnosus in a weight ratio of 1: (2-3): (0.5-1) as probiotics, and the synbiotic feed additive prepared has a better growth-promoting effect on beef cattle, and can make the feed conversion rate of beef cattle better.

[0072] The broiler feeding test was conducted using the broiler feed provided in Application Examples 21-40 and Comparative Application Examples 5-8. The immune organ indexes (thymus index, bursa index and spleen index) of the broilers in the above broiler feeding test were then tested. The results are shown in Table 4 below.
[0073] The test method is as follows: (1) A total of 100 one-day-old AA+ white-feathered broiler chickens (half male and half female) were randomly divided into 25 groups, with 4 chickens in each group (half male and half female). The experimental period was 42 days.
[0074] (2) Among them, 20 groups were fed with the animal feed provided in Application Examples 21-40 (experimental groups 1-20); 5 groups were fed with the animal feed provided in Comparative Application Examples 5-8 (control groups 1-4); and 1 group was fed with commercial feed (purchased from Shandong Jiju Biotechnology Co., Ltd.) as a blank control group. During the experiment, all conditions were basically the same, immunization and deworming were carried out according to routine procedures, feeding was carried out twice a day, food and water were freely available, feces were cleaned once a day, and the sink was scrubbed once a day.
[0075] (3) After the broiler feeding experiment, the broilers were weighed, dissected, and their thymus, bursa of Fabricius, and spleen were collected and weighed. The immune organ index was then calculated and the average value of the immune organ index of each group was obtained. The immune organ index calculation formula is as follows: Immune organ index (mg / g) = immune organ weight / total chicken weight Table 4 Test results of broiler immune organ index
[0076] According to the test results in Table 4, the various immune organ indexes of broilers fed with the broiler feed provided in Application Examples 21-40 are greater than the various immune organ indexes of broilers fed with the broiler feed provided in Comparative Application Examples 1-4 and commercially available feed. Therefore, it is shown that the synbiotic feed additive provided in this application can improve the immunity of animals, thereby improving the health level of animals, increasing breeding benefits, and has good economic value and application prospects.
