Cows must have hay in their feed

Dry grass refers to the timely harvesting of wild grasses or cultivated grasses that have been dried and dried. High quality hay is characterized by its dark green color, rich in protein, minerals and vitamins, aromatic and palatable. Compared with juiciness and concentrates, hay is bulky, contains many celluloses, and is difficult to digest. However, it is an important part of the diet, in addition to supplying dairy cows with nutrients, it also plays a balancing role in physiology, it is an important raw material for the formation of milk fat, and can promote gastrointestinal motility. Studies have shown that the dry matter content of dairy cows varies from 3% to 5%, which is called the balance material—that is, about 1% of the cellulose of the filling material. Hay is an important raw material for the formation of milk fat, which produces volatile fatty acids such as acetic acid, propionic acid, butyric acid, and fatty substances in the process of breaking down cellulose by rumen microorganisms. These substances are important raw materials for the synthesis of milk fat. If the amount of hay fed is too low, the fat rate will decrease. Therefore, hay is the most important forage for dairy cows. Dairy cows have a large rumen volume and special features that use a lot of hay. The daily feeding amount can reach more than 3% of the cow's weight. The hay content in the diet should generally be not less than 5 kg. Modulation of grass hay should be cast at the heading stage; legumes or other hay can be castrated during flowering. The moisture of green hay should be below 15%, green, aromatic, soft stems, more leaves, less impurities. After drying, it should be tied and set up for storage to prevent nutrient losses. When feeding cows, the cut length should be 3 to 5 cm.

Stainless Steel Wire Mesh

Stainless Steel Wire Mesh


The stainless steel mesh is classified according to the varieties: stainless steel plain mesh, stainless steel twill mesh, stainless steel bamboo mesh, stainless steel mat mesh, contrast mesh, stainless steel paper net, etc.
The stainless steel mesh is made of metal wires such as 302, 304, 304L, 316, 316L, 310, 310s, etc. The surface is smooth, rust-free, corrosion-resistant, non-toxic, hygienic and environmentally friendly. Uses: hospitals, pasta, meat barbecue, life flower baskets, fruit basket series mainly stainless steel wire mesh, using electropolishing technology for surface treatment, the surface is bright as a mirror.
Stainless steel is heat resistant, acid resistant, corrosion resistant and wear resistant. Because of these characteristics, stainless steel mesh is widely used in mining, chemical, food, petroleum, pharmaceutical, etc., mainly for gas, liquid filtration and other media separation.
