Problems solved by technology

Appropriate VFA is beneficial to the development of rumen epithelial cells, but excessive VFA accumulation in the rumen can easily cause a decrease in rumen pH and cause rumen acidosis
[0006] In ruminant nutrition research, there are problems such as high manpower and material resources input, high test intensity, large individual differences, and lagging adjustment of feeding management measures. The i

[0055]Literature search and data screening

[0056]The literature search uses databases such as China HowNet to screen relevant literature data for the past 10 years. The acceptance criteria are: the experimental animals are dairy cows, beef cattle, sheep and goats; the literature reports the composition and nutritional components of the diet (additives, RDS, peNDF, etc.); the experimental indicators are the rumen fermentation parameters (pH, TVFA content, molar ratio of VFA, propylene acetate Acid ratio). The RDS in the diet is based on the reported value in the literature. If the data is not reported in the article, use the CPM-Dairy software to estimate these parameters. A total of 55 articles and 78 sets of valid data were obtained.

[0058]Stepwise regression analysis modeling

[0059]Using stepwise regression analysis, stepwise regression calculations were performed on the 9 indicators of diet formula and animal information and the corresponding 10 rumen fermentation parameter indicators, and the equations and determination coefficients related to 10 rumen fermentation parameter indicators were obtained respectively (Table 1). R2max=0.50, which does not meet the modeling requirements.

Abstract

The invention provides a rumen volatile fatty acid prediction method, system and equipment and a medium, and belongs to the technical field of nutrition regulation and prediction. By analyzing existing data, a rumen volatile fatty acid prediction model is constructed, and then rumen fermentation is predicted according to daily ration information and animal information. The optimal prediction modelis obtained through screening, the ruminant nutrition law is effectively disclosed, and the ruminant nutrition test result is predicted. The method and system play a pre-test role to a certain extent, effectively avoid invalid test risks before the test is carried out, also can provide reference in the test period to timely adjust feeding management, and improve the research efficiency, so that the method and system have a good practical application value.

Description

technical field [0001] The invention belongs to the technical field of nutrition regulation and prediction, and in particular relates to a method, system, equipment and medium for predicting rumen volatile fatty acids. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] When the feed enters the rumen, carbohydrates such as cellulose, hemicellulose, and starch in the feed are fermented and digested by bacteria and decomposed into glucose, which is continuously degraded by microorganisms and finally degraded into volatile fatty acids (VFA). The VFAs produced in the rumen are mainly acetate, propionate and butyrate. They are rapidly converted to acetate, propionate and butyrate...
