Effects of Dietary Energy Levels on Rumen Fermentation, Microbial Diversity, and Feed Efficiency of Yaks (Bos grunniens)

Frontiers in Microbiology, 2020
The microbial community of the yak (Bos grunniens) rumen plays an important role in surviving the harsh Tibetan environment where seasonal dynamic changes in pasture cause nutrient supply imbalances, resulting in weight loss in yaks during the cold ...

Effects of leucaena and yeast on rumen fermentation and methane emissions in cattle [PDF]

, 2008
Este trabalho foi realizado com o objetivo de avaliar os efeitos do uso de leucena e levedura em dietas para bovinos sobre o metabolismo ruminal, incluindo o pH e as produções de ácido graxos voláteis (AGV), amônia e gás metano. Quatro bovinos machos com

Invited review: Plant polyphenols and rumen microbiota responsible for fatty acid biohydrogenation, fiber digestion, and methane emission: Experimental evidence and methodological approaches.

Journal of Dairy Science, 2019
The interest of the scientific community in the effects of plant polyphenols on animal nutrition is increasing. These compounds, in fact, are ubiquitous in the plant kingdom, especially in some spontaneous plants exploited as feeding resources ...

A heritable subset of the core rumen microbiome dictates dairy cow productivity and emissions

Science Advances, 2019
Cow genes dictate environmentally friendly microbiomes: a step towards reducing greenhouse gas emissions. A 1000-cow study across four European countries was undertaken to understand to what extent ruminant microbiomes can be controlled by the host ...

In vitro effect of pH on resistance of ruminal bacteria to intracellular potassium depletion, and effect of pH and ionophores on ammonia and microbial protein production Efeito do pH in vitro sobre a resistência de bactérias do rúmen à perda de potássio intracelular e efeito do pH e de ionóforos sobre a produção de amônia e proteína microbiana

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2005
Ruminal fluid from steers fed on pasture was incubated with artificial media at pH 5.5 and 7.0 in two experiments. In the first, the effect of monensin level on resistance of ruminal bacteria to potassium depletion was evaluated; in the second, effects ...

Ruminal silage degradability and productivity of forage and grain-type sorghum cultivars Degradabilidade ruminal das silagens e produtividade de cultivares de sorgo de tipo forrageiro e granífero

Scientia Agricola, 2003
Forages for feeding dairy cows should conciliate the potential for high dry matter yield per unit area, maximizing animal stocking rate, with high nutritive value, which enables decreasing the amount of concentrate feedstuffs per milk unit produced ...

Addressing Global Ruminant Agricultural Challenges Through Understanding the Rumen Microbiome: Past, Present, and Future

Frontiers in Microbiology, 2018
The rumen is a complex ecosystem composed of anaerobic bacteria, protozoa, fungi, methanogenic archaea and phages. These microbes interact closely to breakdown plant material that cannot be digested by humans, whilst providing metabolic energy to the ...
