Pigs have a relatively simple digestive system, and the hay, silage, or pasture grass are not available for pigs to utilize. So the farm-grown grains, such as the wheat bran, rice bran and corn meal, etc. are frequently used as the single feed, or the compound feed by mixing them with a nutrients supplement that includes protein, vitamin and minerals, etc. According to feed appearance, the compound feed can be divided into feed meal, pellet feed, crushed feed, extruded feed, compressed feed, liquid feed, floating feed, cubed feed, etc. Animal feed pellet machine can produce premium feed pellets which greatly help pig grow healthily and it can be divided into two types: flat die feed pellet mill and ring die feed pellet mill.
Uses Of Pig Feed Pellet
Pig feed plays different roles for pig production. Piglets eat the feed mainly for growth and maintenance, mature pigs use feed primarily for maintenance and reproduction, the digested feed that is not for growth, maintenance, or reproduction is reserved as body fat. 1. For growth: feed helps the increase in size of bone, muscle and skin cells. 2. For maintenance: feed supplies the energy for normal pig activities and recover of worn body tissue. 3. For reproduction: feed supports the growth and development of unborn pigs during the gestation, from mating to farrowing. And high-quality feed helps pigs lactation performance. 4. For fattening: feed facilities the formation and deposition of fat tissue under the skin, around muscles and in the body cavity. The ring die feed pellet mill machine can make high-quality pig feed pellets.
Pig Feed Pellet Size And Pellet Quality
Pig feed pellet size has two dimensions: the feed pellet diameter and the feed particle size (the grinding fineness of ingredients). The conventional wisdom shows that small pigs prefer feed pellets with small diameter and large pigs prefer feed pellets with large diameter. But a lot of experiments indicate that pellet diameter has no significant influence on pig performance, the particle size is a leading factor affecting feed quality.
Impact Of Feed Pellet With Different Particle Size On Pig Performance
Particle size is the mean geometric diameter of particles measured in microns and the geometric mean standard deviation of the particle distribution. 1. Impact on pig gastrointestinal tract and digestive function Experimental results express that coarse grinding will lead adverse reaction, cornification and damage to pig gastrointestine, thus affecting the nutrients absorption. However, fine grinding will increase feed process cost and may result in feed bridging, dust problems and the incidence of gastric ulcers (increase of gastric acid and pepsin activity is the origin) in swine. 2. Impact on feed efficiency When the particle size of feed ingredients is reduced, the surface area of the cereal is increased. This will allow greater interaction with digestive enzymes, which helps a lot with the improvement of feed conversion rate. Fusmar Machinery not only provide a full set of pig feed pellet production line but also provide a single machine in each production process.
Optimum Particle Size for Pig Feed Pellet
Application of make swine pellet feed with the optimum particle size would be featured by maximum feed utilization rate, best pig performance & health condition, and high economic benefit. The optimum particle size for pig feed pellet is determined based raw material varieties and pig growth stages, taking physiological characters of pigs, effect of crude fiber on pig physiology, and the situation of pig raising and pig feed producing into consideration. In a word, the effects of particle size on pig performance are the interactions between age of the pig, grain type, and particle size.
