Gelatinized starch urea with zeolite powder as carrier and preparation method

Abstract

Belonging to the technical field of ruminant feed, the invention discloses a gelatinized starch urea with zeolite powder as the carrier and a preparation method. The gelatinized starch urea comprises,by mass percentage, 20% of urea, 75% of corn flour, and 5% of zeolite powder. The invention employs zeolite powder to replace the bentonite of other products to serve as the carrier so as to acquirea gelatinized starch urea product with better quality. No melamine is detected in the gelatinized starch urea product, and the melamine content is 90.2mg / kg, therefore the gelatinized starch urea belongs to safe product. The starch gelatinization degree is 88.3%, the gelatinization degree and stability are both obviously higher than those of similar products on the domestic market. The degradationamount of the urea product in rumen increases gradually along with the extension of fermentation time, no rapid degradation phenomenon occurs in a short time, and the slow-release effect is good. Theratio of nitrogen supplied by gelatinized starch urea is less than 20% of the feedstuff total nitrogen, the gelatinized starch urea increases the daily gain and feed intake of fattening cattle, lowers the feed conversion rate, and has obvious economic benefits.

Description

technical field [0001] The invention belongs to the technical field of ruminant feed, and in particular relates to a gelatinized starch urea with zeolite powder as a carrier and a preparation method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] 1. my country's protein feed resources are in short supply [0004] The shortage of protein feed resources is one of the bottleneck factors restricting the development of animal husbandry in my country. my country's protein feed raw materials mainly include soybean meal, rapeseed meal, cotton meal, fish meal, etc., of which soybean meal accounts for about 70% of protein supply. In 2017, my country imported 95.54 million tons of soybeans (the source of soybean meal), while the domestic soybean production in that year was about 13 million tons, that is, my country's soybean dependence on the international market reached 88%. In addition, my country ...

AI Technical Summary

Problems solved by technology

[0012] In summary, the existing problems in the prior art are: the quality and safety parameters of different gelatinized starch urea products in the prior art are quite different, and the release rate of ammonia nitrogen is relatively fast, and the release rate of ammonia nitrogen in some products is close to the limit. The release rate of treated pure urea shows that its sustained release effect is poor;
