Method for determining fermentation degree of pannage microbial fermentation bed padding

Abstract

The invention relates to a method for determining the fermentation degree of pannage microbial fermentation bed padding, which comprises the following steps of: mixing different batches of padding in the same amount with sodium chloride solutions at different concentrations, and obtaining the dry weight of the padding on the upper layer and the padding on the lower layer by conventional operation to calculate the suspension rates of the padding in the sodium chloride solutions at different concentrations; screening variables by taking a padding fermentation level (Y) as a dependent variable and the suspension rates of the padding in the sodium chloride solutions at different concentrations as independent variables through multivariate stepwise regression; and obtaining a regression equation by taking degree of freedom P of less than 0.05 as the introduction standard and degree of freedom P of more than 0.10 as the rejection standard and utilizing data processing system (DPS) version 7.05 analytic software to obtain a fermentation index model of the pannage microbial fermentation bed padding. The method has the advantages that: the quantitative measuring of the fermentation degree of the padding can be measured; the operation is simple; the relative error is low; and the reliability is excellent.

Description

【Technical field】 [0001] The invention relates to a method for discriminating in the field of agricultural breeding, in particular to a method for discriminating the degree of fermentation of pig-raising microbial fermentation mattress materials. 【Background technique】 [0002] Pig breeding in microbial fermentation bed is to lay thick bedding in the livestock house, the excrement of pigs is mixed with the litter and fermented and decomposed, and the feeding and excrement treatment are completed in the livestock house at the same time. It is under the action of beneficial microbial strains A new environmentally friendly pig raising technology with no pollution, zero emissions, and a virtuous circle. At present, more and more large-scale and formal pig breeding bases have adopted microbial fermentation bed technology. Compared with the traditional pig raising mode, this technology has many advantages, such as solving the problem of manure treatment, improving the growth envi...

Problems solved by technology

However, this ideal condition cannot be achieved in the general normal breeding process, so it is difficult to quantitatively characterize the fermentation degree of litter, lack of reliability and operability, and due to the lack of quantitative measurement indicators, it is very easy to cause subjective errors caused by human beings

Especially in the later stage of litter fermentation, the misjudgment rate is higher, which is not conducive to the scientific management of the fermentation bed
