Problems solved by technology

[0003] Excessive addition of trace elements in pig feed is a common problem in the prior art. The utilization rate of inorganic trace elements in animals is low, and the discharge amount is large, causing heavy metal pollution such as copper, iron, mercury, lead, etc. Organic trace elements should be used instead of inorganic Trace elements, improve the utilization rate of trace elements, save mineral resources and reduce environmental pollution
[0004] In addition, the pig feed in the prior art generally uses wheat bran as one of the main components, because wheat bran is rich in cellulose and vitamins, so wheat bran is very important to the growth of pigs and to improve the nutritional value of pork, but wheat bran is maintaining It is very easy to get damp during the process, and its storage time is short. The general storage time is one month, and after the wheat bran is harvested, it is easy to mold and produce aflatoxin. If the wheat bran containing aflatoxin is continued to be used to feed pigs, the Not only is it harmful to the growth of pigs, it is easy to cause pigs to get sick or die, and if people use these pork containing aflatoxin, it is easy to dissolve in human body poisoning or carcinogenic,

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a pig feed. Background technique [0002] At present, the pig industry has developed rapidly and has become an important part of my country's animal husbandry. The environmental problems caused by the pig industry are becoming more and more serious. Pigs excrete a large amount of undigested and absorbed nutrients such as nitrogen and phosphorus through feces and urine every day. Balancing nutrient needs, improving feed utilization and reducing nutrient discharge are of great significance for improving the economic benefits of the entire pig production and reducing environmental pollution. [0003] Excessive addition of trace elements in pig feed is a common problem in the prior art. The utilization rate of inorganic trace elements in animals is low, and the discharge amount is large, causing heavy metal pollution such as copper, iron, mercury, lead, etc. Organic trace elements should...
