Embodiment 1

[0030] An animal feed prepared by using threonine fermentation waste, which is prepared according to the following method:

[0031] Step 1) Filtration and decolorization of threonine fermentation broth: the threonine fermentation broth is sterilized by microfiltration membrane filtration, and the retentate and filtrate are collected respectively; Permeate: Combine the above-mentioned retentate and concentrated solution into feed liquid A for later use; pump the permeate into the decolorization tank for decolorization treatment, add activated carbon accounting for 1% of the permeate mass in the decolorization tank, and control the temperature in the decolorization tank to 45°C , after decolorization for 30 minutes, remove activated carbon by plate and frame filtration to obtain feed solution B; wherein, the microfiltration membrane is an inorganic ceramic membrane with a molecular weight cut-off of 2000MW, and the microfiltration temperature is 40°C; the ultrafiltration membrane...

Embodiment 2

[0043] An animal feed prepared by using threonine fermentation waste, which is prepared according to the following method:

[0044] Step 1) Filtration and decolorization of threonine fermentation broth: the threonine fermentation broth is sterilized by microfiltration membrane filtration, and the retentate and filtrate are collected respectively; Permeate: Combine the above-mentioned retentate and concentrated solution into feed liquid A for later use; pump the permeate into the decolorization tank for decolorization treatment, add activated carbon accounting for 1% of the permeate mass in the decolorization tank, and control the temperature in the decolorization tank to 45°C , after decolorization for 30 minutes, remove activated carbon by plate and frame filtration to obtain feed solution B; wherein, the microfiltration membrane is an inorganic ceramic membrane with a molecular weight cut-off of 2000MW and a microfiltration temperature of 40°C; the ultrafiltration membrane ha...

Embodiment 3

[0056] Feed effect test prepared by the present invention:

[0057] 1. Select 300 pigs infected with classical swine fever, the age of which is between 2 and 4 months; the symptoms are: unknown high fever, loss of appetite or disappearance, conjunctivitis with purulent secretions, and purulent mucus often flow out of the nasal cavity , with vomiting and blood in the stool; there are often many spot-like bleeding or large red spots on the skin of the base of the ear, abdomen, and medial thigh. Mesenteric lymph nodes are swollen, often with hemorrhagic enteritis, and button ulcers in the mucosa of the large intestine. They were randomly divided into three groups, 100 in each group; all three groups were treated with Qingwenbaidu powder, 20g per 1kg of body weight, for 7 consecutive days.

[0058] Experimental group: given the feed prepared in Example 1 of the present invention; control group 1: given Tongwei medium and large pig compound feed; control group 2: given the feed of...

Abstract

The invention belongs to the amino acid fermentation waste liquid processing field and discloses a feed prepared by threonine fermentation waste, the preparation method comprises the steps as follows: 1) filtering the threonine fermentation liquid and decolorizing, 2) separating the crystal and the mother liquor, 3) hydrolyzing, 4) preparing composite medicine powder, 5) preparing the main material, and 6) preparing the feed. The preparation method for the feed is also provided. The feed effectively uses the threonine fermentation waste for greatly reducing the feed preparation cost, improving the nutritional ingredient and turning waste into treasure.

Description

[0001] technical field [0002] The invention belongs to the field of amino acid fermentation waste liquid treatment, and discloses a feed prepared by using threonine fermentation waste and a preparation method thereof. [0003] Background technique [0004] Threonine is an essential amino acid, which is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed. With the wide application of lysine and methionine synthetic products in compound feed, threonine has gradually become an The main limiting factor for the growth of livestock and poultry. Threonine is mainly used as a feed additive. Its production steps are concentration, crystallization, and extraction of bacterial protein. However, the processing of bacterial protein and mother liquor produced in the process is difficult and costly, and it is difficult to obtain cost-effective by-products. [0005] In recent years, the price of livestock feed has continued to rise, which has red...
