China is accustomed to refer to pigs weighing less than 15 kg as suckling pigs. The feed used in this stage is called suckling pig feed. With the improvement of pig raising level, the accelerated development of the feed industry and the rapid development of large-scale pig farms, the pig feed has been subdivided into two stages in the market for pig-producing areas, namely high-grade suckling pigs (also known as teaching materials). ) and general suckling pigs. It is generally considered that the feed material refers to the feed used when the pig starts feeding 5 days after the birth and until 10 days after the weaning. Generally, the piglet feed refers to the feed used by the piglets after weaning for 10 days to 15 kg. Qqm China Feed Industry Information Network - based on feed, serving animal husbandry

In order to produce good quality piglets, it is best to measure starch gelatinization rate, soluble protein, fishmeal freshness, peroxide value and some health indicators such as Salmonella. Qqm China Feed Industry Information Network - based on feed, serving animal husbandry

The quality control and processing of suckling pigs are almost the same as those of other pigs. There is not much speciality. Only some heat-sensitive raw materials are used. Special attention should be paid to controlling the granulation temperature and quenching time. The quenching and tempering temperature has a great influence on starch gelatinization. It is reported that there is a negative correlation between the tempering temperature and the degree of gelatinization. The greater the difference between the temperature of the granulator and the pellets, the higher the degree of gelatinization.

The suckling pig pellets cannot be made too hard, too hard and seriously affect the palatability. Due to the physiological characteristics of the digestive tract of the suckling pig and the digestibility of the feed, the degree of starch gelatinization is required to be higher. Therefore, other methods are needed to appropriately reduce the hardness of the suckling pig material. Therefore, it is particularly important to choose a suitable compression ratio ring mode. Generally, the granulation ring mode compression ratio is 6-8. If the bulking material is used much, the compression ratio is 3, and the material made in this way is crisp, but the powder rate is higher.

After the pulverized corn and soybean are pulverized, there is generally no problem with the particle size. From the comprehensive consideration of various factors, the particles are suitable at 400-600 microns. Qqm China Feed Industry Information Network - based on feed, serving animal husbandry

If making powder, pay attention to mixing uniformity. According to reports, when the feed mixing variation coefficient of piglets decreased from 106.5% to 28.4%, the average daily gain increased by 41%, feed utilization increased by 18.52%, and feed intake increased by 18.33%. Therefore, the feed mixing time of weaned piglets should reach 4-6 minutes, and the coefficient of variation should be no more than 10% according to the requirements of China's compound feed standard to ensure the feed is fully mixed and the nutrient composition is evenly distributed. Therefore, it is best to take 2 pulverization processes (mixed and smashed once), so that the appearance of the product looks like a single raw material, and it will be more uniform.

The gelatinization rate of the particles has a huge impact on the performance of the animal. According to reports, increasing the gelatinization rate by 5%-10% can increase the animal performance by 3%-5%, and has the same effect on suckling pigs.
