Journal Article
Use of sugar beet silage in feedlot cattle diets
TL;DR: En Ensiling offers a means of preserving the feeding value of beets for cattle, but the beets must be competitively priced to ensure feed costs per kilogram of liveweight gain are not increased.
Journal ArticleDOI
Animal Feed Science and TechnologyAssociations among nutrient concentration, silage fermentation products, in vivo organic matter digestibility, rumen fermentation and in vitro methane yield in 78 grass silages
Kim Viggo Weiby,Sophie J. Krizsan,M. Eknæs,Angela Schwarm,Anne Cathrine Whist,Ingunn Schei,Håvard Steinshamn,Peter Lund,Karen A. Beauchemin,Ingjerd Dønnem +9 more
TL;DR: In this article , the impact of silage quality on methane (CH4) production is largely unknown, but the authors expected that silage nutrient concentrations and silage fermentation products would affect CH4 yield and that these factors could be used to predict the methanogenic potential of the silages.
Journal ArticleDOI
Effect of kernel processing and particle size of whole-plant corn silage with vitreous endosperm on dairy cow performance.
G.G.S. Salvati,W.P. Santos,J.M. Silveira,V.C. Gritti,B.A.V. Arthur,Pedro Augusto Ribeiro Salvo,L. Fachin,A.P. Ribeiro,N.N. Morais Júnior,Luiz F. Ferraretto,João Luiz Pratti Daniel,Karen A. Beauchemin,Flávio Augusto Portela Santos,Luiz Gustavo Nussio +13 more
TL;DR: Evaluating for lactating dairy cows the effects of kernel processing and TLOC of WPCS with vitreous endosperm found cows fed SP6 had lower chewing time and tended to have greater levels of serum amyloid A compared with PT6, which is an indication of more complete biohydrogenation in the rumen.
Journal ArticleDOI
Postnatal differential expression of chemoreceptors of free fatty acids along the gastrointestinal tract of supplemental feeding v. grazing kid goats
T. Ran,Yan Liu,J. Z. Jiao,C.S. Zhou,Shaoxun Tang,M. Wang,Zhixiong He,Zhiliang Tan,W.Z. Yang,Karen A. Beauchemin +9 more
TL;DR: Results suggest that enhanced expression of chemoreceptors for FFAs might be one of the benefits of early supplemental feeding offered to young ruminants during early development.
Journal ArticleDOI
Forage proportion and particle length affects the supply of amino acids in lactating dairy cows1
TL;DR: The results indicate that increasing dietary F:C ratio decreased overall AA supply because flow to the duodenum and intestinal digestibility of AA were decreased, however, increasing FPL had no effect on AA supply.
