Under normal feeding conditions, the feed cost of dairy cows accounts for more than 60% of the production cost of fresh milk. Therefore, the rationality of diet matching not only relates to the performance of dairy cows' health and production performance, but also the utilization of feed resources, and directly affects the economic benefits of dairy cow production. The factors affecting dairy cows' diet include: cow weight, milk production, milk composition (percentage of milk fat, milk protein), milk lactation stage, and cow parity. The following factors can affect the use of nutritionally balanced diets by dairy cows: 1Pacability of diets; 2 Number of feedings per day; 3 Feeding methods; (eg Complete mix feeding method, computer controlled concentrate feeding method and Coarse rear fine feeding method, etc.); 4 feeding methods; (alone feeding or group feeding). The basic principles for dairy cows' rations: 1 Based on feeding standards, and for specific conditions (such as ambient temperature, feeding methods, feed quality, processing conditions, etc.), make necessary adjustments. 2 We must make full use of local feed resources and properly match feed. For example, malt roots, corn germ cakes, etc. can be used to reduce the cost of feed and save fine material. 3 We must pay attention to the overall balance of nutrition, according to the quality of the feed price or season, feeding methods, and properly adjust the ratio of relevant raw materials in the feed formulation. In addition, we must choose raw materials with suitable volume and good palatability.

Dynamic disinfection is a process of disinfection and cleaning of air and surfaces in indoor Spaces. A
new method of safe disinfection that does not cause harm or interference to people and the environment on
site.The charged particles and active oxygen components produced by the low-temperature plasma in the
equipment play a major role in the process of killing bacteria and viruses, and have the effect of
broad-spectrum sterilization. It can not only inactivate aerosol plankton in the air and bacteria
and viruses on the surface of object but also effectively decompose formaldehyde and volatile organic
compounds, degrade all kinds of bad smell and purify it Air environment.A small amount of high purity
zone.
Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in air purifiers that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.
