Autor: P. J. Tamayao, K. H. Ominski, S. Robinson, K. M. Wittenberg, G. Crow, E. J. McGeough

Publikováno v: Animal Production Science. 63:237-248

Context Dietary manipulation is an important means to mitigate methane emissions; however, relatively few options exist for forage-based diets. Aims This batch culture study evaluated the effects of crude protein (CP) and fat concentration on ruminal

Publikováno v: Canadian Journal of Animal Science. 102:396-400

This study evaluated the effects of seven biochar products at two levels of inclusion [2.25% or 4.50% diet dry matter (DM)] on DM disappearance (DMD), cumulative gas and methane (CH4) production, ammonia-nitrogen, and volatile fatty acid (VFA) produc

Relationship between residual feed intake and radiated heat loss using infrared thermography in young beef bulls

Autor: G. H. Crow, S. Thompson, A.L. Schaefer, J. Colyn, K. H. Ominski, John A. Basarab

Publikováno v: Journal of Thermal Biology. 78:304-311

Residual feed intake (RFI) has been used to select metabolically efficient cattle in beef breeding programs, particularly for sire selection. Adoption of genetic selection using RFI has been limited due to the cost and difficulty of measuring individ

BOARD-INVITED REVIEW: Quantifying water use in ruminant production1

Autor: E. J. McGeough, Stephan Pfister, Tim A. McAllister, Getahun Legesse, M. Martel, Arjen Ysbert Hoekstra, Roland Kroebel, Karen A. Beauchemin, K. H. Ominski, Marcos R. C. Cordeiro

Publikováno v: Journal of Animal Science. 95:2001-2018

The depletion of water resources, in terms of both quantity and quality, has become a major concern both locally and globally. Ruminants, in particular, are under increased public scrutiny due to their relatively high water use per unit of meat or mi

Effects of post-pyrolysis treated biochars on methane production, ruminal fermentation, and rumen microbiota of a silage-based diet in an artificial rumen system (RUSITEC)

Autor: A.M. Saleem, E. J. McGeough, Tim A. McAllister, K. H. Ominski, Erasmus Okine, Gabriel O Ribeiro, Paul Tamayao, Hee-Eun Yang

Publikováno v: Animal Feed Science and Technology. 273:114802

This study investigated the effects of including biochars, which differed in post-pyrolysis treatment, on nutrient disappearance, total gas and methane (CH4) emissions, rumen fermentation, microbial protein synthesis and rumen microbiota in an artifi

To determine the effect of supplementing dry-rolled corn during mid- to late-gestation in cows fed low-quality forage on feed intake, body weight (BW), and body condition score (BCS), plasma metabolites, and neonatal growth, 47 multiparous cows (661

344 Grazing behavior and performance of bred beef heifers grazing stockpiled perennial or annual forages in western Canada

Autor: Doug Cattani, E. J. McGeough, K. H. Ominski, J Dahmer, G. H. Crow, K. M. Wittenberg

Publikováno v: Journal of Animal Science. 96:171-172

This study compared grazing behavior and performance of bred beef heifers while stockpile grazing in late fall/early winter. Four stockpiled forage treatments were grazed for 2x28 d grazing periods near Brandon, Manitoba, Canada. Treatments included:
