Embodiment 1

[0026] This embodiment relates to a motherwort extract feed additive; its preparation specifically includes the following steps:

[0027] Step 1. Naturally dry the motherwort leaves, remove impurities, dry at 60°C for 6 hours, crush them, pass through a sieve with a pore size of 0.6mm, add 12ml of ethanol solution per gram of motherwort, add 80wt% ethanol solution for immersion for 4 hours; add an ultrasonic extractor In the process, ultrasonically extract at room temperature and 115KHz for 45min; after the extraction is completed, filter to obtain the filtrate and solid residue a; evaporate under reduced pressure to remove the ethanol in the filtrate to obtain the first extract;

[0028] Step 2, add 8 times the amount of water to the solid residue a, boil for 5 hours, and filter at a steam pressure of 0.5 MPa to obtain the second extract and solid residue b;

[0029] Step 3, add 6 times the amount of water to the solid residue b, boil for 3 hours, and filter at a steam pressu...

Embodiment 2

[0040] The purpose of this example is to consider the influence of pH value on the dry paste rate and the extraction rate of active components in the water extraction step after ultrasonic extraction. The preparation of this example is the same as in Example 1, the difference is that in step 2, acetic acid is added to adjust the pH value of water to 5.5, 6.0, and 6.5, and in step 3, saturated sodium hydroxide is added to adjust the pH value of water to 8.0 and 8.5 , 9.0, forming 9 experimental groups; the pH values ​​of the experimental groups 1 to 9 corresponding to steps 2 and 3 are 5.5, 8.0, 5.5, 8.5, 5.5, 9.0, 6.0, 8.0, 6.0, 8.5, 6.0, 9.0, 6.5, 8.0, 6.5, 8.5, 6.5, 9.0.

[0041] With motherwort medicinal material 100g, the present embodiment, embodiment 1 and comparative example 1 are carried out comparative test; Details are as follows:

[0042] Determination of dry paste rate: Mix and concentrate the first, second, and third extracts obtained in the above nine experiment...

Embodiment 3

[0049] This embodiment relates to a kind of motherwort extract feed additive; Its preparation is the same as embodiment 1, the difference is:

[0050] Step 1. Pass through a sieve with a pore size of 0.5 mm, add 10 ml of ethanol solution to each gram of Motherwort, add 85 wt % ethanol solution and soak for 5 hours; ultrasonically extract for 35 minutes under the condition of 110KHz;

[0051] Step 2, boil for 4 hours, steam pressure 0.4MPa;

[0052] Step 3: Boil for 5 hours, and the steam pressure is 1.7MPa.

Abstract

The invention discloses a feed additive with motherwort herb extract and a preparation method of the feed additive. The feed additive adopts the motherwort herb extract and a carrier as materials; the motherwort herb extract is prepared by adopting ultrasonic-assisted water extraction method. In the preparation process of the feed additive, the material waste is less, the content of active components in the extract is high, the extract yield is high, and the benefit to improving the feed effect and reducing the production cost is achieved; the prepared feed additive has good adjusting function for endless lochia and retained fetal membranes and the like after delivery of female animals.

Description

technical field [0001] The invention belongs to the field of Chinese herbal medicine feed, and in particular relates to a motherwort extract feed additive and a preparation method thereof. Background technique [0002] With the advancement of the industrialization of the aquaculture industry, the promotion of improved breeds and the improvement of breeding levels, the extensive use of antibiotic growth-promoting drugs, and the continuous increase of various stress effects, various viruses, bacteria and non-bacteria caused diarrhea, Symptoms such as diarrhea and various respiratory diseases are increasing day by day. With the increasing drug resistance of viruses and bacteria, the large-scale invasion of various bacteria and viruses has caused outbreaks of diseases. Blue ear disease, unknown high fever, various vaginitis, endometritis, postpartum retained placenta, endless lochia, various respiratory diseases, and postpartum sows with no milk or less milk have seriously affe...
