Problems solved by technology

Secondary fermentation can increase the sugar loss of silage by 10% to 24%, and also produce toxins. If cattle and sheep eat such feed, they will not only fail to achieve the desired effect, but will also cause their production performance and milk and meat quality to decline.
However, in actual production, silage is mostly after opening. Due to the reduction of the nutritional level of silage due to secondary fermentation, which affects the feed intake and production performance of livestock, the protection and improvement of the quality of silage after opening is particularly important. important
However, there are not many researches on the protection of silage quality after opening, and it is urgent to develop additives that can effectively protect the quality of silage after opening.

[0025] Experimental Example Secondary Fermentation Inhibitor Effect Verification

[0026] 1. Test material

[0027] Whole-plant corn silage: The mixed and chopped whole-plant corn silage used in a dairy farm in Luoyang City, Henan Province was selected in this experiment, with a dry matter content of about 75%. Sampling was taken from the silage pit, and the part about 10 cm thick at the mouth of the pit was discarded. The sample was corn silage raw material that had been crushed to 1-2 cm by a grinder.

[0028] Acid: 3 kinds of organic acids (formic acid, dehydroacetic acid, propionic acid) to be mixed, all of which are chemically pure or above, with a purity of 99%.

[0029] 2. Experimental design

[0030] Formic acid, dehydroacetic acid, propionic acid are mixed according to the ratio of table 2, form the product of 25 different proportionings, wherein the numbering of embodiment 1 is 9, the numbering of embodiment 2 is 24, the numbering of embodiment 3 is 25, the embodim...

Abstract

The invention provides a silage secondary fermentation inhibitor, and the silage secondary fermentation inhibitor capable of inhibiting secondary fermentation of silage contains formic acid, dehydroacetic acid and propionic acid, can effectively inhibit proliferation of saccharomycetes and molds in the silage and significantly improve aerobic stability of the silage, thereby inhibiting aerobic fermentation after cellar opening, slowing down mildewing and deteriorating and loss of nutrient substances of the silage, and improving the nutrition level and the storage time of the silage. The inhibitor disclosed by the invention is readily available in raw materials, relatively low in cost, simple in preparation method and capable of remarkably inhibiting secondary fermentation of the silage and protecting the quality of the silage after cellar opening, with a good large-scale application prospect.

Description

technical field [0001] The invention belongs to the field of animal feed, and in particular relates to the processing and preservation of silage. Background technique [0002] With the continuous improvement of people's living standards, the proportion of meat, eggs, and milk in the diet structure is increasing, which promotes the rapid development of animal husbandry. Among them, cattle and sheep breeding require a large amount of forage, and silage such as corn silage ( Whole plant corn silage, corn stalk silage, etc.) have the characteristics of softness, juiciness, aroma, good palatability, high nutrient retention rate of raw materials, less loss of carotene and protein, and high digestibility. Quality plays a very important role. [0003] However, in the practical application of silage, secondary fermentation is a serious problem. The secondary fermentation is the entry of aerobic microorganisms (mainly fungi and yeast) with the air during the taking process after the...
