preparation example Construction

[0022] A kind of preparation method of poplar extract feed additive, concrete steps are as follows:

[0023] Respectively shorten poplar flowers and bark, wash and pick them;

[0024] Put the raw materials into a multifunctional extraction tank, boil for 1 hour with 6 times the amount of water, and process with a steam pressure of 1Mpa, filter to obtain the first filtrate and filter residue;

[0025] The filter residue was passed through 6 times the amount of water again, boiled for 1 hour, and the steam pressure was 1Mpa, and filtered to obtain the second filtrate and filter residue respectively; the filter residue was discarded;

[0026] Mix the first filtrate and the second filtrate and concentrate to D=1.19-1.2 to obtain the extract extract;

[0027] Put the extract into a container and keep it refrigerated at 1-4°C;

[0028] The extract enters the spray dryer, the air inlet temperature is 180°C, and the outlet air temperature is 70°C, and a dry powder of poplar extract ...

Embodiment 1

[0032] The present invention will be described in detail below in conjunction with the examples.

[0033] During 2008.09.20----2008.10.20, the experimental animals in Dongjiang Animal Husbandry Co., Ltd., Shantou City used the late-growing Du Da Sanyuan pigs. The results of the control addition test were carried out as follows

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...
