Mixed silage feed and preparation method
Technical field
The invention belongs to technical field of animal, in particular to a kind of mixed silage feed and preparation method.
Background technique
In northern China, as soon as crops are mostly that a season is ripe, therefore autumn and winter will appear the phenomenon that fodder grass lacks, especially
It is fresh green fodder grass.Peasant's majority is fed with hay, this feed mode, significantly reduces the nutritional ingredient of forage grass and agreeable to the taste
Property.If being processed by ensiling, the ensilage being made into is not only similar to the nutritive value of green forage, but also palatability is good.
In addition, ensilage can solve the problems, such as that northern area winter greenfeed lacks with long-term preservation.
Feeding sugar grass is a mutation for grain sorghum, has the advantages that high photosynthetic efficiency, high biological yield and high sugar content,
As the energy, feed and sugar source the crop most attention by countries in the world.Feeding sugar grass cauline leaf is rich in amino acid, dimension life
Element, minerals etc., full of nutrition, leaf juice content is more, and soluble sugar content is high in stem, and high conversion rate, palatability is good, is animal husbandry
The important feed crop of development is the preferred forage crop for making ensiling.
Although feeding sugar grass is easy production ensiling since soluble sugar content is abundant, feeding Sweet sorghum silage feed
Crude fiber content higher its nutritive value is caused to be affected.In addition, domestic animal eats the digestibility of hemicellulose or cellulose
