Method for increasing feed value of straw and reducing methane emission from ruminant livestock

Abstract

The present invention discloses a method for increasing a feed value of straw and reducing a methane emission from ruminant livestock. The straw is air-dried, the air-dried straw is cut into straw sections with a length of 1.5-2.5 cm by a straw cutter; urea and ammonium nitrate are dissolved distilled water and prepared into a solution, the solution is evenly sprayed on the cut straw sections, thestraw sections are fully stirred evenly, the stirred straw sections are put into a fermentation bucket, the straw sections are compacted tightly layer by layer, a fermentation bucket lid is tightly sealed, a mouth sealing is conducted using a sealing film, and the sealed straw sections are preserved at a temperature environment of 20-25 DEG C; the straw sections are preserved after set days and taken out from the fermentation bucket, the straw sections are air-dried, at the same time, residual ammonia is dispersed, and the treated straw sections can be used for feeding the ruminant livestock.The product has advantages of being suitable in additive amounts, free of toxin to the livestock, easily obtained in raw materials, simple in operation processes, low in costs, stable in quality, easy for preservation, easy for industrialized production, etc. At the same time, a use of the straws can effectively alleviate environment pollutions caused by a direct combustion.

Description

technical field [0001] The invention relates to the technical field of agricultural resource utilization, in particular to a method for increasing the feeding value of rice straw and reducing the methane emission of ruminant livestock. Background technique [0002] Rice is one of the most important food crops in my country. While providing food, about 200 million tons of straw are produced every year. These straws are valuable crop resources. However, the current management and utilization methods are relatively extensive, and the harvested straws have not been fully utilized. The direct field burning of a large amount of rice straw has caused serious environmental pollution and caused a series of social problems. Rice straw is an important traditional roughage resource for ruminant livestock, but it is not easy to degrade and has low nutritional value. At the same time, methane is one of the most important greenhouse gases. Excessive consumption of low-quality roughage by r...

Problems solved by technology

[0003] The main purpose of the current chemical treatment methods for crop straw is either to increase the value of straw forage or to reduce methane emissions from ruminant livestock. In combination, this technology combines the needs of improving feed value and reducing methane emissions into one, achieving a good double effect

At the same time, the additive amount of urea and ammonium nitrate is the focus and key, if the additive amount is too low, it will have no effect, but if the additive amount is too high, it will poison livestock
