Autor: Meng M. Li, S. Ghimire, B.A. Wenner, R.A. Kohn, J.L. Firkins, B. Gill, M.D. Hanigan

Publikováno v: Journal of Dairy Science, Vol 105, Iss 11, Pp 8879-8897 (2022)

ABSTRACT: To investigate the effects of acetate, propionate, and pH on thermodynamics of volatile fatty acids (VFA) in the rumen, a dual-flow continuous culture study was conducted to quantify production of major VFA, interconversions among the VFA,

Metatranscriptomic analyses reveal ruminal pH regulates fiber degradation and fermentation by shifting the microbial community and gene expression of carbohydrate-active enzymes

Autor: Meng M. Li, Robin R. White, Le Luo Guan, Laura Harthan, Mark D. Hanigan

Publikováno v: Animal Microbiome, Vol 3, Iss 1, Pp 1-17 (2021)

Abstract Background Volatile fatty acids (VFA) generated from ruminal fermentation by microorganisms provide up to 75% of total metabolizable energy in ruminants. Ruminal pH is an important factor affecting the profile and production of VFA by shifti

USING NUTRITIONAL STRATEGIES TO MITIGATE RUMINAL METHANE EMISSIONS FROM RUMINANTS

Autor: Jian SUN, Guangyong ZHAO, Meng M. LI

Publikováno v: Frontiers of Agricultural Science and Engineering, Vol 10, Iss 3, Pp 390-402 (2023)

● Microbial fermentation in the rumen is a main source of methane emissions.● Nutritional strategies can effectively mitigate methane emissions by manipulating biochemical reactions in the methanogenesis pathways.● Mitigation practices must be

Thiocyanate increases the nitrous oxide formation process through modifying the soil bacterial community

Autor: Jian Gao, Meng M. Li, Guangyong Zhao

Publikováno v: Journal of the science of food and agricultureREFERENCES. 102(6)

BACKGROUND Nitrous oxide (N2 O) is a potent greenhouse gas depleting the stratospheric ozone. Previous studies reported that the thiocyanate (TC) excretion in the urine of cattle fed rapeseed meals containing glucosinolates was positively correlated

Using artificial neural networks to predict pH, ammonia, and volatile fatty acid concentrations in the rumen

Autor: Srijan Sengupta, Meng M. Li, Mark D. Hanigan

Publikováno v: Journal of Dairy Science. 102:8850-8861

The objectives of this study were (1) to predict ruminal pH and ruminal ammonia and volatile fatty acid (VFA) concentrations by developing artificial neural networks (ANN) using dietary nutrient compositions, dry matter intake, and body weight as inp

A revised representation of ruminal pH and digestive reparameterization of the Molly cow model

Autor: Meng M. Li, Mark D. Hanigan

Publikováno v: Journal of dairy science. 103(12)

Ruminal pH is a critical factor to regulate nutrient degradation and fermentation. However, it has been poorly predicted in the Molly cow model, and recent improvements in the representation of nitrogen cycling across the rumen wall altered some of t
