Sorghum sudanense and corn mixed silage feed and manufacture method thereof

Abstract

The prevent invention discloses a sorghum sudanense and corn mixed silage feed and a manufacture method thereof, relates to the silage feed and the manufacture method thereof, and aims to solve problems that during manufacture or use processes, existing whole plant corn silage feeds are liable to produce aflatoxin. The silage feed is prepared from sorghum sudanense, corn stalk and corn cobs. The manufacture method is as follows: during a corn milky ripe stage, corn is harvested, crushing and soaking by using edible salt are conducted, the salt, corn stalk, corn cobs and sorghum sudanense are successively spread in a silage silo with a V-shaped cross section, and finally, sealing storage is conducted. The sorghum sudanense and corn cobs added to the corn stalk provide sufficient fermentation substrates for lactic acid bacterium fermentation and the corn cobs are beneficial to rapid and large-scale reproduction of lactic acid bacteria; edible salt water is used to soak the corn cobs to reduce the amount of air; the manufacture method is beneficial to compaction and air discharge of the silage raw materials; and corn cob crushed particles fill gaps to facilitate the discharge of the air in the raw materials. The manufactured silage feed is relatively good in sensory identification results. The manufacture method is suitable for preparing the sorghum sudanense and corn mixed silagefeed.

Description

technical field [0001] The invention relates to silage and a preparation method thereof. Background technique [0002] With the development of animal husbandry, silage corn has been paid more and more attention as a feed source for ruminants. Silage corn is rich in nutrients, high in non-structural carbohydrates, low in lignin, high in yield per unit area, has more dry matter yield at harvest, and has higher energy than other silages. [0003] Corn cob is the fruit shaft left after the corn cob is removed from the kernel. It is characterized by high crude fiber content, but poor palatability and low digestibility, which limit its application in animal breeding. The annual output of corncobs in my country is about 30 million tons, most of which are burned as fuel, causing environmental pollution and waste of resources. [0004] The winter in the north is relatively long, and fresh forage is scarce, so silage is the most economical feed for ruminant feeding. In the process ...
