In order to produce high-quality piglets, it is essential to monitor several key factors such as the starch gelatinization rate, soluble protein content, freshness of fishmeal, peroxide value, and health indicators like Salmonella. These elements play a critical role in ensuring that the feed supports optimal growth and development in young pigs.
The quality control and processing of feed for suckling pigs are largely similar to those used for other pigs, with only minor differences. However, certain heat-sensitive ingredients require special attention. Controlling the granulation temperature and quenching time is especially important, as these factors significantly affect the starch gelatinization process. Research suggests that there is a negative correlation between tempering temperature and the degree of gelatinization. A greater temperature difference between the granulator and the final pellets can lead to higher gelatinization levels, which is beneficial for digestibility.
Suckling pig pellets should not be too hard, as excessive hardness can reduce palatability and negatively impact feed intake. Due to the sensitive digestive system of newborn pigs, the feed must have a high level of starch gelatinization. To achieve this while maintaining an appropriate texture, it’s crucial to select the right compression ratio ring mode. Typically, a compression ratio of 6-8 is recommended. If bulking agents are used, the compression ratio can be reduced to 3, resulting in a crisp texture but potentially increasing the powder rate.
After grinding corn and soybean meal, particle size is generally well-controlled. Considering various factors, a particle size range of 400–600 microns is usually ideal for weaned pigs, as it balances digestibility and efficiency.
When producing powdered feed, mixing uniformity is vital. Studies show that reducing the feed mixing variation coefficient from 106.5% to 28.4% can increase average daily gain by 41%, improve feed conversion by 18.52%, and boost feed intake by 18.33%. Therefore, it is recommended that mixing time for weaned pig feed be at least 4–6 minutes, with a coefficient of variation no higher than 10%, as required by China's compound feed standards. To ensure even distribution of nutrients, it is advisable to use two grinding processes—mixing and grinding once—to create a more uniform appearance, resembling a single raw material.
The gelatinization rate of the feed particles has a significant impact on animal performance. Reports indicate that increasing the gelatinization rate by 5–10% can enhance animal performance by 3–5%, with similar benefits observed in suckling pigs. This makes it a crucial factor in formulating high-quality feed for young livestock.
flashlight is a handheld electronic lighting tool, usually consisting of battery powered bulb and focusing mirror. The history of the flashlight can be traced back to the early development of human society, from torches, oil lamps, candles to electric lamps, and finally developed into the modern LED flashlight. The invention of the flashlight combined the invention of the battery and the light bulb, and despite its relatively simple design, it was not widely used until the late 19th century. Early flashlights have a Flashlight that doesn't hold enough battery power, and it's called a "flashlight," meaning a short light. With the advancement of technology, flashlights have undergone many changes, from incandescent bulbs to xenon bulbs, and finally developed to modern LED flashlights.
There are many types of modern flashlights, including strong flashlights, rechargeable flashlights and so on. The strong flashlight uses light-emitting diode (LED) as the light source, which has the advantages of power saving, durability and strong brightness. Rechargeable flashlight is a handheld electronic lighting tool that can be used for repeated charging, usually using LED bulbs, long life, suitable for night out, power outage lighting. In addition, there are multi-function hand flashlight, using the principle of hand power generation, can be used for emergency lighting or for mobile phones and other digital products charging.
Flashlights are not only used for daily lighting, but also play an important role in emergency situations. For example, multifunctional hand torches generate electricity by hand, providing lighting and charging functions for environments without power. Military flashlights (also known as tactical flashlights) are widely used in military and police operations because of their high brightness, high illumination and strong light suppression.
