Embodiment approach

[0017] Experiment 1. Effects of different additions of lactic acid bacteria on the quality of fermented dry rice straw

[0018] In this experiment, three additions of lactic acid bacteria were set, which were 2.5×10 5 , 5×10 5 , 1×10 6 . Set up two controls, respectively blank control 1 (without adding molasses and lactic acid bacteria), and control 2 (only adding molasses group).

[0019] Experimental design: cut dry straw to 5cm, add water, lactic acid bacteria with different contents, and 3% sugarcane molasses to mix evenly to make the water content 60%, weigh 200g and put it into a 40cm×30cm polyethylene bag, 3 for each group 3 repetitions, a total of 3*5=15 groups, sealed with vacuum sealer, and stored in the dark at room temperature.

[0020] The micro-storage time was 14 days, and samples were taken from bags to analyze the quality of fermented rice straw.

[0021] Experiment 2. Effects of different molasses and different additions on the quality of fermented dry r...

Abstract

The invention discloses a preparation method of dry straw fermented feed, which comprises the following steps of: uniformly mixing dry straws, lactic acid bacteria and molasses, and starting sealed stacking fermentation to obtain the fermented feed; wherein the fermentation conditions comprise a first condition and a second condition, wherein the first condition is that the fermentation time is 7-14 days at a temperature of 20-35 DEG C, and the second condition is that the fermentation time is 14-28 days at a temperature of 10-20 DEG C; when the fermented feed is obtained through the fermentation under the first condition, the fermented feed is used within 60 days after the fermentation is started; when the fermented feed is obtained through the fermentation under the second condition, thefermented feed is used within 90 days after the start of the fermentation. The method can obviously improve the content of crude protein and soluble sugar of the fermented dry straws, improve the nutritional quality and digestibility of the dry straws, increase the content of organic acids such as lactic acid, acetic acid and the like, improve the palatability of the straws, and is beneficial toimproving the intestinal tract health of animals.

Description

technical field [0001] The invention belongs to the field of recovery and utilization of by-products of agricultural production, and in particular relates to a method for preparing dry rice straw fermented feed. Background technique [0002] Rice straw is the main by-product of agriculture in my country. Due to the lack of effective utilization methods, a large amount of rice straw is discarded or burned on the spot, which not only wastes a lot of resources, but also causes environmental pollution. In recent years, as people pay more and more attention to the ecological environment, how to use straw as a resource to alleviate the burning phenomenon has become a hot research direction. Rice straw feeding is an important way to utilize rice straw as a resource, and it is also an important means to solve the shortage of roughage in herbivore feeding. [0003] In the utilization of straw feed, crushing, ammoniation, and silage are the main technical means for fresh straw; direc...
