Problems solved by technology

At present, there are hog feeds developed using cassava as raw materials. For example, CN105010879A discloses hog feed obtained by fermenting cassava dregs and other raw materials and mixing them with premixed materials. Most of the raw materials used are processing waste products. It is not applicable to underdeveloped areas, and the sources of raw materials are few; as CN107960541A discloses cassava flour and rice bran, wheat bran, corn stalks, sweet potato leaves, alfalfa, radish leaves, shepherd's purse, mineral matter, iodized salt, the meat of the premix proportioning Special feed for pigs, but the proportion of cassava flour in its feed formula is small, and cassava cannot be fully utilized

Abstract

According to the pork pig feed with the cassava as the main raw material and the preparation method of the pork pig feed, the problem that the cassava tuberous roots are low in protein content is solved by adding the cassava leaves, the soybeans and the rat beans into the cassava tuberous roots, and the corn and the mixed bran are added to supplement dietary fibers, so that the pork pig feed is prepared. Bone meal and lysine are added to improve the amino acid mode of cassava tuberous roots, meanwhile, mountain flour, thymin, multivitamins and zinc-containing auxin are added, so that nutritional ingredients in the formula feed are more balanced, the feeding performance is better, different proportions are adopted for pork pigs with different weights, and the formula feed is more scientific; the cassava tuberous roots, the cassava leaves and the rat beans are treated, so that the content of toxic substances contained in the cassava tuberous roots, the cassava leaves and the rat beans is reduced to be within a safe range, meanwhile, antinutritional factors in the soybeans are reduced, the feed conversion efficiency is improved, and the working procedure that the cassava and the soybeans need to be cooked thoroughly in the traditional feeding process is omitted.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a pig feed with cassava as the main raw material and a preparation method thereof. Background technique [0002] Traditional pig feeds focus on high protein and high energy, which can easily lead to indigestion in pigs, and the feed utilization rate is low, nutrients cannot be fully absorbed, pigs grow slowly, high breeding costs, and low economic benefits. [0003] The root tuber of cassava is a kind of feed material rich in starch, low in protein and high in energy, which has the advantages of low cost and fast weight gain. However, due to its insufficient protein content, it can only make pigs grow fat, not lean meat, and lack minerals and vitamins such as calcium and phosphorus in cassava. Feeding pigs with single cassava for a long time will affect the growth and development of pigs and cause pigs to lose weight. Slow growth and early fattening. Cassava is a cost-effec...
