At the moment when the epidemic situation has not subsided, this grand meeting is still held in the form of an online round table. In addition to invited experts, animal husbandry people from all over the world also picked up their mobile phones or computers to participate in the industry grand gathering online. According to the live data statistics of the four major platforms, as of June 10, the cumulative number of online viewers of Yunfeng meeting for feed industry development 2020 was 157 000 And set a new high in the industry.

As a special guest of the summit, Feidi group was represented by Chairman Liu Chunhai and general manager Tao Chunwei of Additives Division. At the meeting, general manager Tao Chunwei explained the topic of "practical application of plant essential oil to ruminants under double epidemic situation", analyzed the essence of plant essential oil, explained the function characteristics of plant essential oil for ruminant, and explained the action principle of plant essential oil for ruminant according to ruminant rumen characteristics.

1. In recent years, there have been various dilemmas in the feed industry, such as African swine fever, which are greatly affected by the market. Many people say that the feed industry has been devastated by the market. So, how to stabilize the R & D team of the enterprise and ensure the survival and development of the enterprise at present and in the future?

Hello, everyone. Our Feidi group was founded in 1996 and has always been led by technology research and development. I am also responsible for R & D work. We are the first company that has done rumen research and formed products in China. In 2004, we obtained the production license of rumen passing series products of the Ministry of agriculture. The technologies of rumen passed methionine, rumen lysine and rumen choline of ruminant animals have filled in the domestic blank, rumen glucose and rumen vitamin technology have filled in the world gap, and rumen glucose has been obtained in China China and the United States invented patents, and put forward the theory of postpartum glucose metabolism imbalance for the first time in the world, which made up for the defects of the theory of negative energy balance in the perinatal period, and made a significant contribution to the development of dairy industry. In addition, we are also the first enterprise to apply coating technology to plant essential oil, so our plant essential oil has always been at the forefront of China in recent years, which is inseparable from our emphasis on scientific and technological innovation and constant adjustment of coating technology. Although it is very late to enter the international market, we have opened up markets in Southeast Asia, European Union, South America and other regions. At present, more than 30 countries are using our essential oil products. We are positioning ourselves as a technology-based enterprise focusing on technology R & D, with R & D personnel as the leader. In terms of stabilizing the R & D team, we use a sense of achievement and bonus to motivate employees.

2. What is the amount of essential oil added to ruminants, and can it be used at young stage?

Our ruminant essential oil has been researched and developed since 12 years ago. So far, the technology has been very mature. At present, our ruminant essential oil has also been put into the production of sheep feed, cow feed and beef cattle feed. Generally, we add 200g. In general, calf and lamb can also use the essential oil of pig. The essential oil we use in the teaching material is jingli'an type I, and the added amount is 300g, which can prevent diarrhea.

3. What is the application value of plant essential oil in the aspect of anti-tumor? How to choose essential oil as plant feed factory?

We've been working on this plant essential oil for 14 years. Plant essential oil can be used together with antibiotics when there are antibiotics. In addition to its antibacterial effect, it can increase the bioavailability of antibiotics by 3-5 times. In addition, our experiments show that plant essential oil can strengthen the four intestinal barrier, for example, in the microbial barrier, it can increase the number of lactic acid bacteria and bifidobacteria, reduce the number of Salmonella and Escherichia coli, in the chemical barrier, it can improve the activity of amylase, trypsin and lipase, in the mechanical barrier, it can maintain the integrity of intestinal mucosa, improve The height of the villi... And so on. After the prohibition of resistance in Europe, plant essential oil has been selected as the first choice of plant additives. After the next prohibition in China, plant essential oil will play an irreplaceable role. As for the selection of plant essential oil by feed factory, it is suggested to screen through these processes: first, operate in the laboratory to see whether the smell is strong or light. If the smell is strong, the stability is not very good. If it is a light fragrance, then the stability is much better. The second is to evaluate the particle size. The third is to put the plant essential oil into the bottom of the bottle and keep it open. The content is measured once a week to evaluate the stability. Plant essential oil can be added to the premix and checked once a month to see what changes in its retention rate are. It can also be added to the granular material to observe the difference between before and after granulation, and so on. The stability of plant essential oil can be evaluated by these changes. In addition, it is also a good way to check the quality of plant essential oil through treatment, such as whether the animal diarrhea can be controlled in time. Finally, the evaluation of production performance is done, which is a complete evaluation process of plant essential oil quality.
