Pig premix feed and pig compound feed

Abstract

The invention discloses a pig premix feed and a pig compound feed. The pig premix feed comprises lignocelluloses with the mass percent content of 10 to 50 percent. According to the pig premix feed, the lignocelluloses replace bran to serve as a fiber source of the feed, according to growth and development characteristics of pigs in all stages, a proper amount of lignocelluloses is added in the premix feed, bran is not required to be additionally added during preparation of perfect compound feed, the operation is simple, the nutrient concentration of the feed is higher than that of the traditional recipe, and healthful and efficient breeding can be realized.

Description

technical field [0001] The invention relates to a premix and compound feed, in particular to a premix and compound feed for pigs. Background technique [0002] The importance of fiber nutrition to sows has been generally recognized and affirmed by pig farmers. With the in-depth understanding of fiber, people have found that adding an appropriate amount of fiber to the diet of piglets or fattening pigs can also help the healthy development of the digestive system, increase the volume of the stomach and intestines, form a good microbial flora, absorb toxins, and improve Feed digestibility. Cellulose plays a specific role in the digestion process, and a certain amount of cellulose in the feed is essential, but not all cellulose products can play the corresponding role. For example, bran, which is used as a conventional fiber source for feed, brings problems such as high mycotoxin content, unstable quality, occupying formula space, and reducing feed utilization to pig farms. ...

AI Technical Summary

Problems solved by technology

Traditional premixes are generally used with "premix + corn + soybean meal + bran (or other fiber sources)" in a certain proportion, and the operation is cumbersome

In addition, bran has the following disadvantages: a, easy to mold; b, large amount of addition, takes up too much formula space (10-20%), resulting in low feed energy value, and the protein in the feed is not fully utilized, resulting in waste , and due to the lack of feed energy, the growth rate of pigs is also limited to a certain extent; c. Contains a large amount of phosphorus, oxalic acid and fermentable fiber, which antagonizes the absorption of calcium and combines trace elements, so that the lameness of sows is serious. Decreased bone strength and increased elimination rate of sows. Due to the loss of calcium, the blood calcium concentration is low, which affects sows' delivery and prolongs delivery time; d. Hydrophilic substances in soluble fibers produce jelly, blocking digestive juice and nutrition The combination of substances reduces the digestibility (reports in the literature: for every 1% increase in fiber, the digestibility of energy and protein decreases by 1%); e, a large number of nutrients (energy and protein) that cannot be digested and utilized are absorbed by bacteria in the rear of the intestinal tract Utilization, a large amount of feces, producing a large amount of toxins and odor
