Embodiment 1

[0025] This example provides a wheat straw feed; the wheat straw used was taken from Jinchang City, Gansu Province, and harvested after the grains were harvested on June 30, 2015.

[0026] The wheat straw fermented feed is specifically prepared by the following steps: crush the wheat straw into segments of 2 to 3 cm, evenly spray 50 g of the enzyme-bacteria compound preparation per ton, adjust the water content to 70%, compact and bag the One layer of bag is made of polyethylene plastic film, and the second layer of bag is common woven bag), the bag is sealed tightly, and fermented for 45 days to get final product;

[0027] The enzyme-bacteria compound agent contains: cellulase 25,000 U / g, xylanase 250,000 U / g, β-glucanase 500,000 U / g, Lactobacillus plantarum 2.8×10 9 cfu / g, Lactobacillus Brucella 1.2×10 9 cfu / g.

Embodiment 2

[0029] This embodiment provides a rice straw fermented feed; the rice straw used is taken from Jilin City, Jilin Province, and the variety is Daohuaxiang, which was harvested after the grains were harvested in 2014.

[0030] The rice straw feed is specifically prepared by the following steps: crush the rice straw into a segment of 2 to 3 cm in length, spray 50 g of the enzyme-bacteria compound preparation evenly per ton, adjust the water content to 70%, compact it, and bag it (the first The first layer of bag is made of polyethylene plastic film, the second layer of bag is a common woven bag), the bag is tightly sealed, and fermented for 45 days to get final product;

[0031] The composition of described enzyme bacterium compound agent is with embodiment 1.

Embodiment 3

[0033]This example provides a corn stalk fermented feed; the corn stalks used are taken from Baoding City, Hebei, and the variety is Sanbei 21. On September 30, 2015, when some leaves were still green after picking the ears at the wax ripening stage, the corn stalks were mowed immediately. cut.

[0034] The corn stalk feed is specifically prepared by the following steps: crush the corn stalks into segments of 2 to 3 cm, evenly spray 50 g of enzyme-bacteria compound preparation per ton, adjust the water content to 70%, compact and bag (the first The first layer of bag is made of polyethylene plastic film, the second layer of bag is a common woven bag), the bag is tightly sealed, and fermented for 45 days to get final product;

[0035] The composition of described enzyme bacterium compound agent is with embodiment 1.

Abstract

The invention relates to crop straw-fermented feed. The crop straw-fermented feed is prepared by taking crop straw as a raw material through an enzyme-bacterium complexing agent of cellulase, xylanase, beta-dextranase, lactobacillus plantarum and lactobacillus buchneri. The invention further provides a mutton sheep total mixed ration containing the crop straw-fermented feed. According to the crop straw-fermented feed and the mutton sheep total mixed ration, the straw resource can be fully utilized, the raw materials are easy to obtain, the preparation steps are simple, the cost is low, the growth performance and slaughter performance of mutton sheep can be significantly improved, and the good practical application value is achieved.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a crop straw feed and a preparation method and application thereof. Background technique [0002] As an inevitable product of agricultural production, crop straw is a very valuable biological resource and a sustainable green resource. my country is a large agricultural country with rich straw resources, with an annual output of 700 million tons, ranking first in the world. The three main straws in my country are corn straw, wheat straw and rice straw, with annual output reaching more than 100 million tons respectively. However, due to the rough texture, poor palatability, and low nutrient digestion and utilization rate of crop straw, it has many limitations as feed. Monogastric animals generally cannot use straw, and the digestibility of ruminants to straw is only 20% to 30%. According to reports, only about 25% of my country's crop straw is used for feed, and the rest is used...
