Technical Field

the invention belongs to the field of feeds, and particularly relates to a pig feed capable of promoting digestion and reducing pig manure odor and a preparation method thereof.

background

with the continuous development of breeding technology, the mouthfeel and the nutritional value of the feed become more important, and in order to promote the growth of pigs, some feeders add some artificial growth promoters and antibiotics for preventing digestive tract diseases into the feed, so that the quality of the feed is greatly reduced by the components, and hidden troubles are left for the health of people.

in the process of breeding pigs, the important points of raising are to improve the utilization rate of feed, accelerate daily gain and reduce the retention and fermentation time of the digested feed in the pigs as far as possible, so that the odor of pig manure is reduced and the environment is beautified. The feed with balanced and comprehensive nutrition needs to be prepared according to each growth stage of the pigs so as to improve the feed absorption, and the existing pig feed has the problems of too high energy raw material ratio, trace element deficiency, few antibacterial and disease-resistant elements and the like.

currently, in existing patents in the field of pig feed formulations; it is important to note that the pig feed for reducing pig manure odor and the preparation method thereof (application number: 201710048259.7) and the deodorized pig feed and the preparation method thereof (application number: 201710044835.0) are reported by Guangxi Shenlongwang farming-pastoral food group Limited, and these patents have focused on the reduction of pig manure odor through the formulation of pig feed formulations, particularly the addition of a certain amount of probiotics to the feed, but considering that the metabolic mode and pathway of microorganisms during the digestion of the feed in the pig body are difficult to control effectively, as a more effective feed formulation is required to ensure that the trace elements and nutrients are completely digested and the pig manure odor is reduced when the pig eats the feed.

most of pig feed formulas or heavy nutrition supply or heavy nutrition absorption are beneficial to fattening by adding probiotics or traditional Chinese medicine components in the formulas, and flavoring agents are used for improving meat quality and taste, so that the pig feed formulas are more. However, the original formulas do not measure the relationship between the odor of the pig manure and the nutrition absorption from the perspective of the physiology of livestock, and how to scientifically prepare the components of the feed to promote digestion and reduce the odor of the pig manure is not considered.
