In vitro ruminal degradation of Tithonia diversifolia

open access: yes, 2021
Introduction. The Mocache canton (Ecuador) is a humid tropical zone, with a dry season of six months, which affects the availability and quality of forage, a situation that reduces the productive and reproductive capacity of ruminants. Objective. To evaluate the apparent in vitro ruminal degradation parameters of dry matter ...

In vitro methods to determine rate and extent of ruminal protein degradation

open access: yes, 2010
Rates of ruminal protein degradation are required in most of the current nutritional models; however, protein degradation in the rumen is very complex and difficult to measure reliably using simple in vitro and in situ methods.

Genetic Variability of Ruminal Starch Degradation of Corn Harvested at Two Silage Maturities [PDF]

open access: yes
This trial was carried out to determine the influence of genotype and maturity stage on ruminal starch degradation of corn harvested at silage maturity. Two types of corn (Zea mays L.), differing in their endosperm texture, flint or dent, were harvested ...

Changes in in vitro ruminal and post-ruminal degradation of tropical tannin-rich legumes due to varying levels of polyethylene glycol.

open access: yes, 2017
We evaluated the effects of tannins from Flemingia macrophylla (CIAT 17403) and Calliandra calothyrsus (San Ramón CIAT 22310 and Patulul CIAT 22316) on in vitro ruminal and post-ruminal dry matter and apparent protein degradation. For each tannin source (

Effect of Calcium Supplementation on Ruminal Soluble Calcium Concentration and Ruminal Fermentation.

open access: yes, 2006
Two experiments were conducted to determine the effect of Ca source and concentration on ruminal soluble Ca concentration and microbial fermentation. In the first study, experimental diets (14 g DM/d) were added to continuous flow culture fermentors in ...
