Embodiment 1

[0097] A biological compound additive feed, which is characterized in that it is composed of raw materials of weight and proportion in the following table

[0098]

[0099] The premix was purchased from Tianjin Wufengnong Biotechnology Co., Ltd., and the product name is 4% Chinese pig compound premix feed (T334);

[0100] The crude extract mixture of mint, astragalus and licorice refers to a mixture of biologically active substances (from Tianjin Yunfeng Breeding Company) formed by natural plant mint, astragalus polysaccharide and licorice through a primary extraction process;

[0101] The organic trace elements refer to: protein copper, protein iron, protein zinc, protein manganese, yeast selenium and potassium iodide, using beer yeast powder as a carrier. Product guarantee value: copper 8.3~10.4g / kg, iron 50~63g / kg, zinc 50~63g / kg, manganese 12.5~15.7g / kg, selenium 250~313mg / kg, iodine 1000~1250mg / kg and moisture ≤ 10%; purchased from Tianjin Aoteqi Biological Products Co., Ltd.

Abstract

The present invention discloses a biological composite additive feed and an application thereof. The biological composite additive feed is characterized in that organic trace elements are used to replace some inorganic trace elements, Chinese herbal medicinal additives are used to improve immunity of animal body, at the same time, probiotics for promoting digestion are added, at the same time, addition of a finished product premix is reduced by 50%, use of antibiotics is reduced, and the composite additive (feed) suitable for growing and fattening pigs is prepared. The biological composite additive (feed) prepared by a method can significantly improve deposition of flavor amino acids (glutamic acid and aspartic acid) in pork, improves quality of the pork, maintains various growth performances of the growing and fattening pigs and maintains or improves feed nutrient digestibility under a premise of reducing the premix by 50%, plays a purpose of reducing use of the antibiotics, increasesbiosafety of live pig products, and has relatively high economic value and environmental benefits.

Description

Technical field [0001] The invention belongs to the technical field of pig breeding, and relates to a biological compound additive feed and a preparation method and application thereof. Background technique [0002] Glutamic acid and aspartic acid are the main savory amino acids, and the side chain R group is an acidic group, which is one of the important precursors for the formation of savory amino acids. At present, most studies on pork umami amino acids are focused on pig breeding, and there are few studies on using pig feed nutrition to promote the deposition of umami amino acids in muscle. It has been reported that adding Chinese herbal medicine additives to the diet can promote the deposition of umami amino acids in pork. The addition of wood vinegar to the diet can also promote the enrichment of umami amino acids to a certain extent. The rest of the research on dietary nutrition regulation of umami amino acids mainly focused on the addition of alfalfa meal and cellulase....
