Soil biological quality of grassland fertilized with adjusted cattle manure slurries in comparison with organic and inorganic fertilizers [PDF]

open access: yes, 2009
We studied the effect of five fertilizers (including two adjusted manure slurries) and an untreated control on soil biota and explored the effect on the ecosystem services they provided.

Selenium supplementation of lactating dairy cows: effects on milk production and total selenium content and speciation in blood, milk and cheese [PDF]

open access: yes, 2008
Forty-multiparous Holstein cows were used in a 16-wk continuous design study to determine the effects of either selenium (Se) source, selenized yeast (SY) (derived from a specific strain of Saccharomyces cerevisiae CNCM I-3060 Sel-Plex®) or sodium ...

Effects of Incremental Dietary Levels of Ground Flaxseed on Milk Production, Ruminal Metabolism, and Enteric Methane Emissions in Organic Dairy Cows [PDF]

open access: yes, 2012
Ground Flaxseed (Linum uitatissimum) is a lipid supplement that is commonly fed to dairy cows. It is believed that supplemental lipid can change the Fatty Acid (FA) composition in the milk, and decrease methane production. Twenty lactating organic Jersey

Influence of live cells or cells extract of Saccharomyces cerevisiae on in vitro gas production of a total mixed ration [PDF]

open access: yes, 2015
In vitro gas production An interaction effect was observed (P=0.009) between treatment type and treatment dose for the asymptotic GP without interaction effects (P>0.05) for the rate of GP and the initial delay before gas production begins.

Particle size evaluation of total mixed rations in intensive beef production systems

open access: yesItalian Journal of Animal Science, 2007
AbstractSamples of total mixed ration (TMR) were collected periodically in 15 beef cattle farms and submitted to a nutritional and particle size evaluation. Samples of faeces were taken and analysed for pH, consistency, colour and visually ranked for corn residues (Corn Residue Index) from 4 (totally digested) to 0 (very high presence of maize residues)
