Preparation method for microbial straw micro-storage feeds

Abstract

The invention relates to the field of feeds for animal husbandry, and provides a preparation method for microbial straw micro-storage feeds. The method comprises the following steps of (1) activation of a straw fermentation and activation microbial agent; (2) dilution of a strain stock solution; (3) pretreatment of straws; (4) micro-storage of the straws; (5) pit sealing; (6) fermentation management. The feeds prepared by the method are low in cost, and have good benefits, the utilization rate of the straws is increased, the feeding amount of domestic animals is greatly increased, and remarkable economic benefits are created.

Description

technical field [0001] The invention relates to the field of animal husbandry feed, in particular to a method for preparing straw microbial micro-storage feed. Background technique [0002] At present, my country's animal husbandry is developing vigorously, the problem of feed shortage is prominent, and the contradictions between humans and animals competing for food and land are very prominent; straw refers to the general term for stems, leaves and ears of mature crops, usually wheat, rice, corn, potatoes, The remaining parts of oilseeds, cotton, sugarcane and other crops after harvesting seeds, my country is a large agricultural country, and crop straw resources are very rich, usually straw resources are ammoniated to obtain feed with high nutritional value, but per ton of straw ammoniated It needs 30-50kg of urea, which is costly and there is a conflict between animal husbandry and planting. Another method is to use microorganisms to convert straw fiber into enzymes with hi...

[0002] At present, my country's animal husbandry is developing vigorously, the problem of feed shortage is prominent, and the contradictions between humans and animals competing for food and land are very prominent; straw refers to the general term for stems, leaves and ears of mature crops, usually wheat, rice, corn, potatoes, The remaining parts of oilseeds, cotton, sugarcane and other crops after harvesting seeds, my country is a large agricultural country, and crop straw resources are very rich, usually straw resources are ammoniated to obtain feed with high nutritional value, but per ton of straw ammoniated It needs 30-50kg of urea, which is costly and there is a conflict between animal husbandry and planting. Another method is to use microorganisms to convert straw fiber into enzymes with high nutritional value that can be used by animals in an anaerobic environment. Protein feed, for grass-fed livestock as the main roughage, this method can reduce feed costs and improve economic benefits

However, due to improper fermentation process or method, the digestible protein content of straw is not high, the nutritional value is low, the feed intake of livestock is small, and other conventional feeds are required, or the steps are complicated, which is not suitable for large-scale applications, and the utilization rate of straw is low. Cannot meet the expected economic benefits
