Effects of Dietary Crude Fiber Content on Sows Production Performance

Adding crude fiber to pig feed can reduce dietary digestive energy concentrations. In order to maintain DE food intake, pigs usually increase feed intake for this feed. However, when the crude fiber content in the diet exceeds 10% to 15%, the feed intake is reduced due to excessive volume or reduced palatability. Among them, we can determine the content of crude fiber in the diet through a fiber analyzer. At low temperatures, sows can increase feed intake so that low-energy (high-fiber) diets can maintain the pig's gestation and lactation needs to the same effect as high-energy diets, but at high temperatures, due to With feed intake limitations, low energy (high fiber) diets are generally difficult to meet for pregnancy and lactation needs. High-fiber diets increase heat stress. If sows are fed high-fiber diets in the summer, they will increase body heat and cause heat stress. In particular, sows in late pregnancy often suffer from wheezing, restlessness, anorexia, and fever due to heat stress, resulting in non-inflammatory breast edema, which is often overlooked by non-dairy, lactating, and pig farmers. The excessive content of crude fiber in the feed will affect the absorption and utilization of nutrients.

High-fiber feeds will accelerate through the gastrointestinal tract, resulting in reduced nutrient absorption and utilization, and poor feed efficiency. The reason is that the first reason is that the microorganisms at the end of the sow's intestine do not have enough time to digest the nutrients in the feed and affect pigs. Only use feed. The second is that under free-feeding conditions, as the crude fiber increases, the energy absorption also deteriorates. Tests have shown that the digestibility of 267.78 kJ can be reduced for every 1 kg of high-fiber feed intake. At the same time, too much cellulose will affect the absorption and utilization of minerals in the feed. The crude fiber analyzer can measure the crude fiber content in feed in a timely manner, helping us to timely adjust the crude fiber content in the feed according to the growth cycle of the sow. If the content of crude fiber in the feed is high, the phytic acid, oxalate, and citrates contained in the feed will form insoluble complexes with the minerals, which will affect the utilization of calcium and phosphorus. The sows themselves have a high demand for calcium and phosphorus. If the amount of crude fiber is too high, the absorption and utilization of calcium and phosphorus will affect the sow's malnutrition, abnormal lactation, and weakness of the sow hindlimb after weaning. If the content of crude fiber is too high, other nutrients in the feed will be relatively reduced, and the amount of single raw materials must be greatly increased, which is also inconsistent with economic principles.

Low levels of crude fiber in the diet can cause a series of problems for pregnant sows and lactating sows. If it is easy to cause sows constipation, the reason may be that the feed stays in the digestive tract for too long, the water absorbs too much, and the stool dries and causes constipation. In addition, digestive tract problems such as stomach ulcers in sows in factory farming may be related to too low dietary cellulose content. If sows in the first trimester of pregnancy are fed low-fiber diets and are limited by the amount of food they eat, it is difficult to feel full, causing problems such as jumps.

POM Sheet Rod

HONYÂ®POM material is usually called acetal (chemical name is polyoxymethylene). HONY can provide POM extruded sheets, bars and pipes, which can be used for machining. POM plastic is a semi-crystalline thermoplastic with high mechanical strength and rigidity. POM plastics have good sliding properties, excellent wear resistance and low moisture absorption. Good dimensional stability, excellent fatigue strength and excellent processing ability make POM material a highly versatile engineering material, even for complex components.

The performance of homopolyoxymethylene (POM-H) and copolyoxymethylene (POM-C) is different. Due to the higher crystallinity, the density, hardness and strength of POM-H materials are also slightly higher. However, compared to POM-H materials, POM-C materials have better chemical resistance, but have a lower melting point.
