Abstract

The invention discloses an antibiotic-substituted feed additive. The additive comprises the following components in percentage by weight: 2-8% of bacterial xylanase, 3-5% of acid protease, 1-2% of phytase, 0.2-0.5% of thymol, 0.2-0.5% of cinnamyl aldehyde, 40-50% of citric acid and 35-45% of corn flour. Under the condition that antibiotics are not added at all, the additive can remarkably improvethe intestinal morphological development of pigs, effectively improve the growth performance and reduce the feed conversion ratio through reasonable compounding of an enzyme preparation and plant essential oil, can completely replace the antibiotics and has an important application prospect in the pig breeding industry.

Description

technical field

[0001] The invention belongs to the technical field of feed additives. More specifically, it relates to an antibiotic alternative feed additive. Background technique

[0002] Antibiotics, as traditional feed additives, have been widely used in the farming industry to prevent or treat livestock diseases. The use of antibiotics has greatly promoted large-scale farming. It mainly suppresses or kills pathogenic microorganisms, reduces the occurrence of animal digestive tract diseases, and improves the digestibility of animal nutrition, thereby promoting the growth of animals. However, the disorderly use and abuse of antibiotics for a long time, and its side effects are becoming more and more obvious. Problems such as drug residues and drug-resistant bacteria caused by the abuse of antibiotics have seriously affected the healthy development of animal husbandry, and even threatened food safety and human health. With the transformation of animal husbandry, the bre...
