Embodiment 1

[0052] Stevia original plant is 95wt% stevia stalks and 5wt% stevia leaves which are pulverized into granules or powder preparations

[0053] The preparation method of stevia extract:

[0054] 1) put stevia powder raw material in water according to the solid-liquid ratio of 1:16, the stevia powder raw material contains 95wt% stevia stalks and 5wt% stevia leaves for extraction, wherein the water bath extraction temperature is Above 95°C, the water bath extraction time is 107min, the ultrasonic-assisted extraction time is 20min, and the ultrasonic intensity is 53kHz;

[0055] 2) The extract obtained after the step 1) is mixed, heated, vacuum-concentrated, and concentrated to Brix 25;

[0056] 3) The concentrated solution obtained after the step 2) was fermented in September to obtain the Stevia rebaudiana extract, and some of its nutritional components are shown in Table 1.

[0057] Table 1 Partial nutritional composition analysis of every 100 grams of Stevia rebaudiana extrac...

Embodiment 2

[0082] The preparation method of Stevia rebaudiana extract:

[0083] 1) put stevia powder raw material in water according to the solid-liquid ratio of 1:16, the stevia powder raw material contains 95wt% stevia stalks and 5wt% stevia leaves for extraction, wherein the water bath extraction temperature is Above 95°C, the water bath extraction time is 107min, the ultrasonic-assisted extraction time is 20min, and the ultrasonic intensity is 53kHz;

[0084] 2) The extract obtained after step 1) is mixed, heated and concentrated in a vacuum until it is concentrated to Brix 25, which is the stevia extract. The stevia extract contains phenols, flavonoids and potassium ions, but the phenols do not include allyl-6-methoxyphenol.

Embodiment 3

[0086] Feed cattle with feed containing stevia

[0087] In the same batch of cattle, some symptoms of malnutrition may appear due to individual differences, manifested as: rough and dull coat, sluggish movement, weakness, less subcutaneous fat, and vitamin deficiency (vitamin A).

[0088] 1. Test method

[0089] 10 cows of malnourished cows in the same batch of cows were set as test group, and were fed the feedstuff that added 0.2% Stevia rebaudiana extract of embodiment 1 in common cattle feedstuff, and the test period of this feedstuff was set as 30 days, during this period , all the cattle were fed at the same time, and the feeding was stopped at the same time, and only the common cattle feed was fed before and after the test period. 10 healthy cows in the same batch of cows were set as a comparison group, fed with the feed that added 0.2% of the stevia extract of Example 2 to the common cattle feed, and the rest were consistent with the test group. 10 healthy cows in the...

Abstract

The invention provides stevia rebaudiana-containing feed and application thereof, and belongs to the technical field of feed. The stevia rebaudiana-containing feed contains original plants of stevia rebaudiana and / or stevia rebaudiana extract, and the stevia rebaudiana original plants are stalks and / or leaves. The stevia rebaudiana extract is prepared by fermentation and cooking of stevia rebaudiana extraction liquid. The stevia rebaudiana extract is rich in antioxidant components, effectively strengthens the immune system functions of a body, effectively reduces the degree of oxidation of fatand cholesterol in muscle, improves the intestinal flora of livestock, increases appetite, and is used for promoting the growth and development of the livestock and / or improving the meat quality of the livestock and / or enhancing the autoimmunity of the livestock and improving the delivery performance of female livestock or improving the growth / productivity of young livestock after birth. The stevia rebaudiana extract can further improve the effects of histamine allergy on the growth of aquatic products, improves the hypoxia tolerance of the aquatic products, and is used for repairing histamine damage to aquatic organisms or improving the antiviral ability of the aquatic organisms or improving the hypoxia tolerance of the aquatic organisms or promoting the aquaculture growth of the aquaticorganisms.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to feed containing stevia and stevia extracts and uses thereof. Background technique [0002] Feed safety affects animal and plant food safety, and affects human health, and even affects the ecological balance of the environment. Feed additives are the key to ensuring feed safety. With the continuous improvement of people's living standards, the requirements for the safety of livestock and poultry products are getting higher and higher, which will inevitably put forward higher requirements for the quality of feed products. It is an inevitable trend of development to replace traditional antibiotics, anti-mildew, antioxidants and other common feed additives with green feed additives with the advantages of disease prevention, health care, growth promotion, no drug resistance, no toxic side effects, and no residues, and has become a worldwide major issues. There are many typ...
