Problems solved by technology

However, fresh potato starch slag cannot be fully utilized as animal feed due to its high water content, low nutritional value, poor palatability, etc., and most of it is discarded as waste, which not only causes waste of resources, but also causes more serious problems. polluted the environment

Embodiment 1

[0013] Embodiment 1, a kind of potato starch dregs mixed silage, is formed by mixing the following components by mass percentage: potato starch dregs 48%, whole plant corn 48%, wheat bran 4%;

[0014] The production method is: chop the whole plant corn with a grinder, and the length is 2-3cm. After wilting and dehydration, add potato starch residue and wheat bran according to the above ratio, mix evenly, add them into the silage pit in layers, and control the water content to 60 -65%, then compacted, sealed, and opened after 45 days.

[0015] For feeding dairy cows:

[0016] A group control experiment was adopted, and the animals were divided into two treatment groups, which were composed of two different silage feeds, and the other feed compositions were the same. All the silage in the control group was whole plant corn silage, and the mixed silage in Example 1 was used in the test group.

Abstract

The invention relates to potato starchy residue mixed silage and application of the potato starchy residue mixed silage. The potato starchy residue mixed silage is characterized by being formed by mixing the following components in percentage by mass: 46-48 percent of potato starchy residues, 46-48 percent of complete stool corns and 4-6 percent of wheat bran. A preparation method comprises the following steps of: chopping the complete stool corns by using a pulverizer to ensure that the length is 2-3cm; adding the potato starchy residues and the wheat bran to be uniformly mixed in the proportion after the corns are withered and water in the corns is removed; adding an ensiling moat layer by layer to control the water content to reach 60-65 percent; compacting and sealing; and unsealing after 45 days. 50 percent of complete stool corns are replaced by the potato starchy residues, and the wheat bran is added again, so that the ensiling is easily carried out, the nutritive value of ensiling stocks is improved, and the milk output of a dairy cow and the milk quality are increased. The dairy cow is fed by using the potato starchy residue mixed silage, so that the milk output of the dairy cow is averagely increased by 10.4 percent, the ensiling raw material cost can be reduced by ** / m3; and mutton sheep is fed by using the potato starchy residue mixed silage, the average daily gain control group is increased by 0.136kg.

Description

technical field [0001] The invention belongs to the field of feed, in particular to potato starch residue mixed silage and application thereof. Background technique [0002] my country is a country that is relatively short of food. According to statistics, in 2010, the feed gap in my country was 100 million tons. Therefore, it is an inevitable choice to develop various non-grain competitive feed resources and develop grain-saving animal husbandry. The use of silage in ruminant feed can not only improve its production performance, but also improve the utilization value of various agricultural and sideline products, thereby alleviating the problem of human and livestock competition for food in our country. At present, the silage in most places in my country only uses corn stalks (or whole plant corn) as raw material, which is limited by the number of corn planted and the area, and the economic cost of aquaculture is increased. [0003] Potato starch residue is a by-product p...
