[0012] Plant polysaccharide, flavonoid extract feed additive Lepida (TF98) instead of antibiotics feeding AA broiler chicken experiment

[0013] 2,000 AA broiler chicks were selected for the test and divided into two treatment groups, one of which was an experimental group (the addition of plant polysaccharides and flavonoid extracts was 1.00 kg / ton respectively) and one control group. The control group used common antibiotic additives (100ppm arsanic acid + 600ppm aureomycin). 1000 1-day-old chicks were divided into 4 replicates per treatment group. The basal rations of each group were exactly the same, they had free access to food and water, and normal feeding management and immunization procedures were used. The test period was 6 weeks (July 10-August 21, 2001). See Table 2:

[0030] Effects of plant polysaccharides and flavonoid extract Yubite (TF100) on growth performance of fish

[0031] Experimental feed: the control group was basic commercial bait, and the test group was 0.2% plant polysaccharides and flavonoid extracts added to the basic bait. See Table 4:

[0032] Table four

[0033]

[0034] The results showed that:

[0035] (1) Adding 0.2% plant polysaccharides and flavonoid extracts to the bait can increase the growth rate of fish by an average of 11.9%, and the growth rate of freshwater pomfret is the most significant, reaching 35.5%;

[0036] (2) Plant polysaccharides and flavonoid extracts are used as aquatic feed additives to help enhance the physique of cultured species. The survival rate of fish in the test group is 100%, while the bream and crucian carp in the control group are both 95%;

[0037] (3) After using plant polysaccharides and flavonoid extracts, the bait coefficient dec...

Abstract

The present invention is one kind of feed additive comprising plant polysaccharide and flavonoid extracted from 11 kinds of Chinese medicinal materials including astragalus root, eucommia bark, pseudostellaria root, etc. The additive is one kind of green feed additive without toxic side effect and medicine residue and may be used to replace antibiotic. Compared with other feed additives, the present invention has low cost, good taste, and the functions of promoting animal's appetite, promoting animal growth, raising animal's immunity and improving quality of animal product.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a plant extract feed additive in livestock and poultry aquaculture feed. Background technique [0002] The top priority for the breeding industry is to improve quality, reduce drug residues, and gradually reduce or even ban antibiotics and other drugs as feed additives. This forces the farming industry to adopt green additives to improve the quality of animal products. [0003] The existing feed additives for livestock and poultry are mainly chemical drug additives. The disadvantage is that long-term use will lead to drug resistance in livestock and poultry, which will bring difficulties to the prevention and treatment of livestock and poultry diseases. Drug residues also bring unsafe factors to humans in addition. Therefore, feed safety is closely related to feed additives, and the safety of additives directly affects feed safety. Extract active ingredients from Chinese herbal med...
