Oral stomach tubing effectively collects ruminal dissolved hydrogen

Rumen Cannula 2

A cannula allows access to the rumen for the research and analysis of the digestive system of cattle.

By Jamie Hawley, ASAS Communications Intern

June 20, 2016 – Ruminal gases include carbon dioxide, hydrogen, and methane. Hydrogen is an essential substrate for methanogens (methane-producing rumen bacteria) to produce methane, and also influences fermentation pathways in the rumen. Dissolved hydrogen is the form of hydrogen available to rumen bacteria.

Little is known about how sampling techniques, including oral stomach tubing with different insertion depths and sampling from different rumen sites through a cannula (see image), affect the measurement of ruminal dissolved hydrogen. Read more »

Heat stress affects pig’s digestive and absorptive capacity

PigBy Jamie Hawley, ASAS Communications Intern

June 13, 2016 – Pigs exposed to ambient temperatures high enough to provoke heat stress change their physiology, metabolism, and behavior to maintain a stable internal environment. As a result, exposure to heat stress may affect the gastrointestinal tract to impair the digestive and absorptive capacity of pigs.

Morales and colleagues at the Universidad Autónoma de Baja California and Evonik Nutrition & Care GmbH have found that heat stress negatively affects the digestive and absorptive capacity of pigs and that the metabolism of some amino acids (proteins) is modified in pigs to counteract the negative effects of the heat stress.
