Beef cattle is suitable for vitamin A supplement

During the growth and development of beef cattle, vitamin A deficiency is a common issue, especially during late autumn. As the grass begins to lignify, its crude fiber content increases while the carotene levels drop significantly. Feeds such as wheat straw, corn stalks, and dried sage grass are low in carotene. Moreover, when cattle are fed more concentrates, which typically have very low carotene content, the risk of deficiency rises further. During the fattening phase, cattle gain weight rapidly, which increases their demand for vitamin A. If the supply of this essential nutrient is inadequate, their feed intake may decrease, and their weight gain will slow down. Therefore, it's crucial to start supplementing vitamin A early in the autumn season to support optimal growth and health. The recommended method is to administer 100,000 units of vitamin A daily, every three days, and then continue with a cyclical pattern. Alternatively, an intramuscular injection of 500,000 to 1,000,000 units can be given every ten days, also following a cycle. These methods not only help maintain good health but also improve feed conversion efficiency and promote better growth in beef cattle. This approach is especially beneficial for farmers looking to maximize productivity during the colder months.

Integrated Roughness Profilometer

Roughness Profilometer, also known as surface roughness meter, surface smoothness meter, surface roughness tester, roughness measurement meter, roughness tester, and other names. It has the characteristics of high measurement accuracy, wide measurement range, easy operation, portability, and stable operation. It can be widely used for the detection of various metal and non-metal processing surfaces. This instrument is a pocket instrument that integrates sensors and hosts, with handheld characteristics, making it more suitable for use in production sites. The exterior design is sturdy and durable, with significant resistance to electromagnetic interference, in line with current design trends.

The application fields of roughness meters include:

1. Mechanical processing and manufacturing industry, mainly metal processing and manufacturing. Roughness meters were originally developed to detect the surface roughness of machined parts. Especially, stylus type roughness measuring instruments are more suitable for detecting hard metal surfaces. For example, the automotive parts processing and manufacturing industry, the mechanical parts processing and manufacturing industry, and so on. As long as these processing and manufacturing industries involve the surface quality of workpieces, the detection application of roughness meters is essential.

2. In the non-metallic processing and manufacturing industry, with the progress and development of technology, more and more new materials are applied to processing processes, such as ceramics, plastics, polyethylene, etc. Some bearings are now made of special ceramic materials, and pump valves are made of polyethylene materials. These materials have a hard texture, and some applications can replace metal materials to make workpieces. During production and processing, their surface roughness also needs to be tested.

3. With the continuous strengthening and improvement of the technology and functions of roughness meters, as well as their in-depth promotion and application, more and more industries have been found to require roughness detection. In addition to mechanical processing and manufacturing, roughness evaluation is also required in the production and processing of power, communication, electronics, such as couplings on switches, integrated circuit semiconductors, and even stationery, tableware, and other products used in people's daily lives The surface roughness of human teeth needs to be tested.
