Poplar tree extract feed additive and preparation method thereof

Abstract

The invention discloses a poplar tree extract feed additive and a preparation method thereof. The preparation is prepared by making extract of flowers and barks of poplar trees by various means and mixing the extract with a carrier uniformly. The preparation method comprises the following steps: 1, performing primary extraction on flowers and barks of poplar trees; and 2, performing secondary circulating extraction on residue obtained after the extraction in the step 1, subjecting the extract obtained at two times to spray drying treatment, and uniformly mixing the dried extract with the carrier uniformly to obtain the poplar tree extract feed additive. The feed additive has antibacterial, antiphlogistic and animal immunity-improving functions.

Description

technical field [0001] The invention relates to a poplar extract feed additive and a preparation method thereof, which has the functions of antibacterial, anti-inflammatory and improving animal immunity, and belongs to the technical field of natural plant additives. Background technique [0002] Pigs of all ages, especially piglets, are characterized by respiratory diseases, which have become one of the main diseases in large-scale pig farms. Among them, the most important porcine respiratory disease syndrome (PRDC) is a disease characterized by reduced growth rate, reduced feed utilization rate, loss of appetite, cough, dyspnea, and diarrhea. Although the overall mortality rate is not high, it can seriously affect pig farms. economic benefits. At present, some new features have appeared in the respiratory disease syndrome. First, the pathogens of mixed infection have changed compared with previous years. The pathogens are Mycoplasma pneumoniae, reproductive and respiratory...
