Abstract

The invention discloses a preparation method of sweet sorghum stretch film wrapped silage for dairy cow feeding, belonging to the technical field of silage preparation. The preparation method comprises the following steps: with fresh sweet sorghum, whole-plant corn, whole-plant soybeans and marigold as main raw materials, adding rumen-protected vitamins, table salt, a chrome amino acid complex, fulvic acid, astragalus membranaceus and other auxiliary materials into the main raw materials; adjusting the moisture content of the mixed raw materials to 60-70%, and compacting, winding and bundlingthe obtained mixed raw material to enable a density to reach 700-850 kg / m<3> and the number of winding layers to be 4-6; wrapping the bundled feed with a special silage stretch film, wherein the number of coating layers during wrapping is 4-8 and the stretch film must be overlapped by 50% or above layer by layer during wrapping, and carrying out fermentation within 6-8 weeks to form the silage. The silage prepared by using the method disclosed by the invention has wine aroma and sour taste, is green in color and luster, is popular among cows, and can relieve the heat stress reaction of the cows.

Description

technical field [0001] The invention relates to a method for making silage wrapped with sweet sorghum stretch film for dairy cow feeding, and belongs to the technical field of silage preparation. Background technique [0002] Sweet sorghum stalks are rich in sugar, with high nutritional value and tall plants, which can produce 6,000 kg to 10,000 kg of green fodder per mu. It is known as a "high-energy crop". It has strong drought resistance, good palatability, and high feed conversion rate. Sweet sorghum can be directly fed green, but the green leaves of sweet sorghum contain cyanoglycosides. It is hydrolyzed during the growth stage to produce harmful substance hydrocyanic acid. Livestock is rich in Hydrocyanic acid in sorghum presents a poisoning hazard. After the sweet sorghum is made into silage, the toxic components will be degraded, so there will be no poisoning, and the sweet and sour are suitable, and the livestock generally like to eat it. According to the feeding ...
