Natural feed additive for improving feed conversion rate and meat quality of livestock and poultry and application thereof

Abstract

The invention discloses a natural feed additive for improving feed conversion rate and meat quality of livestock and poultry and application thereof. The additive is prepared from a folium cortex eucommiae extract, a rosemary extract, mangosteen polyphenol and a mulberry leaf extract. Further, the mass ratio of the folium cortex eucommiae extract to the rosemary extract to mangosteen polyphenol to the mulberry leaf extract is (2-4): (3-5): (0.5-1.5): (1-3); and preferably, the mass ratio of the folium cortex eucommiae extract to the rosemary extract to mangosteen polyphenol to the mulberry leaf extract is 3: 4: 1: 2. Plant extracts which are wide in source and low in price are compounded according to different components and functional characteristics of the plant extracts, and the compound which has antioxidant, anti-inflammatory and bacteriostatic physiological functions and can improve the feed conversion rate and meat quality of livestock and poultry is screened out; and a small amount of additive is added into the basic ration, so that the daily gain of the broiler chicken in the early stage can be obviously increased, the feed-gain ratio in the whole period can be reduced, and the drip loss of pectoralis muscles and the cooking loss of leg muscles can also be reduced.

Description

technical field [0001] The invention relates to livestock and poultry breeding and production of livestock and poultry feed, and specifically discloses a natural feed additive for improving the conversion rate of livestock and poultry feed and meat quality and its application. Background technique [0002] In the last century, antibiotics have long been used in livestock and poultry feed as a class of antibacterial and growth-promoting feed additives. With the development of the economy and the improvement of living standards, people's awareness of the hazards caused by antibiotic residues and drug resistance has deepened, and the demand for high-quality livestock and poultry products has become increasingly strong. The production of safe, healthy and high-quality livestock and poultry products has become a reality. It has become the top priority for the development of my country's aquaculture industry. As my country bans the use of antibiotics in feed, it is of great signif...
