In today's livestock industry, the widespread use of broad-spectrum antibiotics as growth promoters has led to a significant reduction in intestinal bacteria. This decline in microbial populations affects the synthesis of various vitamins within the gut, potentially leading to vitamin deficiencies in animals.
With the advancement of breeding technologies, the productivity of different animal breeds continues to improve. As a result, the metabolic rate of substances in their bodies increases, which in turn raises the demand for essential vitamins. This means that animals now require more nutrients than ever before to maintain optimal health and performance.
Modern animal husbandry is heavily influenced by commercial interests. To maximize economic returns, animals are often kept in conditions that may cause stress—such as overcrowding, fluctuating temperatures, poor air quality, and other environmental challenges. Under these stressful conditions, the metabolic processes in the body speed up, increasing the need for vitamins. If this increased demand isn't met, animals may enter a subclinical disease state, affecting their growth and development. In severe cases, diseases can develop. However, adding extra vitamins to the diet is a cost-effective solution compared to the potential losses from illness, aligning well with modern business practices.
During specific physiological stages, such as pregnancy, lactation, or recovery from illness, animals have a higher requirement for vitamins. These periods demand additional nutritional support to ensure proper development and health.
In summer, high temperatures often lead to reduced feed intake. At the same time, the body’s need for certain vitamins increases due to the heat stress. Therefore, it becomes necessary to increase the vitamin content in feed by a certain multiple to compensate for these losses.
The quality of single vitamins used in feed mills can vary significantly, leading to some degree of loss during storage, mixing, and transportation. Factors like expiration, static electricity, and poor mixing uniformity contribute to this issue. Additionally, the uniform distribution of micronutrients in feed plays a crucial role in ensuring consistent nutrient delivery. Vitamins, in particular, are vital because they are needed constantly in metabolic processes, yet water-soluble vitamins are not stored in the body. Currently, there is no unified standard for testing water-soluble vitamins in China, making it harder to ensure consistency and quality.
Moreover, the quality of raw materials used in feed can also affect vitamin absorption. For example, soybean meal with high urease activity may interfere with the absorption of other nutrients. To counteract this, a safety factor is often applied when determining the amount of vitamins to add. When considering all these factors, it's important to balance the cost of adding more vitamins against the benefits of improved animal health and growth. Finding the optimal benefit-to-cost ratio can enhance feed conversion efficiency and ultimately improve farm profitability.
Planar Beam Load Cells
Planar beam load cells, otherwise known as planar force sensors, are designed for compact solutions where there's limited space. They can be effectively used as single units or as a part of a multi-load cell structure for platform scales.
These innovative sensors are most utilized in applications that require three or four units per instance, focusing on point-of-sale scales or weighing systems ranging from 10 to 400 pounds. Their sleek, low-profile design makes them a preferred choice for a wide spectrum of uses. They find application in medical settings for weighing hospital beds, chairs, infants, and equipment within incubators.
Furthermore, their usage extends to retail sectors, incorporated in checkout counters and retail scales. Agricultural setups also benefit from these sensors for various devices, bench scales being a prime example.
Among these, the ultra-thin flat sensor is a popular choice owing to its portability and aluminum alloy construction. Primarily, it caters to the needs of weight scales, postal scales, and other handheld ultra-thin countertop electronic scales, enhancing convenience and accuracy in the weighing process.
