Preparation method of half-dried forage and half-dried forage and feed

Abstract

The application of the invention relates to the technical field of animal feeds, and discloses a preparation method of half-dried forage. The preparation method comprises the steps of performing steamheating treatment on fresh forage so as to obtain intermediate forage; and performing dehydrating treatment on the intermediate forage to obtain the half-dried forage so that the preparation of the half-dried forage is completed. According to the half-dried forage obtained in a preparation manner disclosed by the embodiment of the invention, the total quantity of digestible nutrients in the half-dried forage of unit mass is increased, so that when the half-dried forage is used as a feed, meeting nutritional requirements of herbivorous livestock type animals is facilitated. Besides, the steamheating treatment is free from climatic influence, and time is controllable, so that the purpose of quickly reducing moisture in the fresh forage can be realized, and the half-dried forage can be quickly obtained in south regions in China. The invention also discloses the half-dried forage and a feed containing the same.

Description

Technical field [0001] This application relates to the technical field of animal feed, for example, to a preparation method of semi-dry forage and semi-dry forage and feed. Background technique [0002] Traditional forage processing methods are mainly hay preparation (air drying and drying) and silage. Due to the rainy days and high air humidity in southern my country, it is difficult to dry the pasture, and even if it is dried into dry grass, it is easy to regain moisture and rot. Therefore, silage is the main method of forage storage and transportation in southern my country. However, southern pastures, such as emperor bamboo grass, hybrid pennisetum, sweet sorghum and other grasses have high water content, and the mechanical harvesting and crushing are carried out at the same time, making the water content of silage raw materials generally reach 80% or more. High-moisture silage not only does not guarantee the quality of the silage, but also has a large volume, requiring mor...
