Embodiment 1

[0018] Example 1. Adding Tangyin Beiai mixed silage and whole plant corn stalks to ferment the feed quality for 60 days

[0019] The present invention selects 60 days as a fermentation cycle to consider the effect of adding Tangyin Beibei Ai on whole plant corn stalk silage.

[0020] Fermentation raw materials: whole plant corn stalks (moisture content 73%) in the milky stage are cut into 2cm segments, and the whole plant (aboveground part) of Tangyinbei Ai in the fully ripened stage is crushed and passed through a 20-mesh sieve for later use.

[0021] 1. Preparation of fermented whole plant corn stalk feed

[0022] Experimental settings: ck (blank group, whole plant corn stalks), 6aa (whole plant corn stalks + 6% Tangyin Bei AI) and 12aa (whole plant corn straw + 12% Tang Yin Bei AI), with 3 repetitions in each group . Put on gloves and grab and mix the whole plant corn stalk and Tangyin Beiai to make it evenly mixed, weigh 100g and put it into a special bag for fermentatio...

Embodiment 2

[0037] Example 2. Feed quality after adding Tangyin Beiai mixed silage whole plant corn stalks fermented

[0038] The present invention selects 60 days as a fermentation cycle to consider the effect of adding Tangyin Beibei Ai on whole plant corn stalk silage.

[0039] Fermentation raw materials: whole plant corn stalks (moisture content 80%) in the milky stage are pulverized through a 30-mesh sieve, and the whole plant (aboveground part) of Tangyin Beibei in the flowering stage is cut into 2cm pieces for later use.

[0040] 1. Preparation of fermented whole plant corn stalk feed

[0041] Experimental settings: ck (blank group, whole plant corn stalks), 6aa (whole plant corn stalks + 6% Tangyin Bei AI) and 12aa (whole plant corn straw + 12% Tang Yin Bei AI), with 3 repetitions in each group . Put on gloves and grab and mix the whole plant corn stalk and Tangyin Beiai to make it evenly mixed, weigh 100g and put it into a special bag for fermentation, then use a vacuum packagi...

Embodiment 3

[0052] Example 3. Analysis of total flavonoid content after fermentation of whole plant corn stalks by adding Tangyin Beiai mixed silage and whole plant corn stalk

[0053] The present invention selects 60 days as a fermentation period to consider the effect of adding Tangyin Beibei Ai on whole plant corn stalk silage.

[0054] Fermentation raw materials: the whole plant corn stalk (moisture content 60%) in the wax ripening stage is cut into 2cm sections, and the Tangyinbei Ai plant (aboveground part) in the flowering stage is cut into 2cm sections for later use.

[0055] 1. Add Tangyin Beiai and mix to prepare fermented whole plant corn stalk feed

[0056] Experimental settings: ck (blank group, whole plant corn stalk), 3aa (whole plant corn stalk + 3% Tangyin Bei AI) and 15aa (whole plant corn straw + 15% Tang Yin Bei AI), with 3 repetitions in each group . Put on gloves and grab and mix the whole plant corn stalk and Tangyin Beiai to make it evenly mixed, weigh 100g and p...

Abstract

The invention relates to the field of biological fermentation feeds, in particular to a method for improving quality of whole-crop corn straw silage by adding Tangyin artemisia vulgaris to improve contents of probiotics, organic acids and flavones. According to the method, artemisia vulgaris is added into whole-crop corn straw for mixed fermentation, according to the mixed fermentation, whole-crop corn straw powder or cut sections and artemisia vulgaris powder or cut sections are stirred and mixed evenly, adding amount of artemisia vulgaris in the whole-crop corn straw is 1-50%, artemisia vulgaris is an overground part of Tangyin artemisia vulgaris in any stage, the artemisia vulgaris is cut into small sections of 2-20 mm, and the artemisia vulgaris powder is obtained by drying and smashing artemisia vulgaris whole plants and then sieving the artemisia vulgaris whole plants through a 10-120-mesh sieve. By adding Tangyin artemisia vulgaris to ferment the whole corn straw, the contents of probiotics, organic acids and flavones are increased, ammoniacal nitrogen is reduced, and flavones are increased; especially in an unsealing stage when the silage is opened after fermentation for feeding, quality of the feed can still be well improved.

Description

technical field [0001] The invention relates to the field of biologically fermented feed, in particular to a method for improving the quality of whole plant corn stalk silage by adding Tangyin Beiai to increase the content of probiotics, lactic acid and flavonoids. Background technique [0002] Corn is one of the most widely planted popular crops in the world, including China. Corn stalks harvested at the milk or wax stage contain good nutrients and are suitable for feeding ruminants. The use of corn stover as animal feed has proven to be economically viable, not only as a way to dispose of corn stover residue, but also as an option for feeding livestock in areas where corn is a major crop. As a result, maize is no longer grown exclusively for human consumption, but increasingly as a valuable feed crop. At present, the national annual output of straw is 259 million tons (2017 data), but only 30% of corn straw is used, which also includes returning to the field with high uti...
