Agriculture contributes approximately 6 to 7% of the total U.S. greenhouse gas emissions. Anim. NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. The grinding and pelleting of forages can reduce emissions by 40%, however the costs associated with this practice may be prohibitive. Agricultural land use by the dairy industry . Livestock represents 31% of the total methane emissions produced from human activities in the U.S., with beef and dairy cattle as the major contributors. Harper, J. Oh, F. Giallongo, M.E.

There has been a lot of research conducted in Canada, Australia, Europe, and the U.S. on strategies to reduce methane emissions from dairy and beef operations. In this article, we review why methanogenesis in dairy cows arises, and how the use of phytogenic product Activo Premium can help achieve efficient energy use and reduced climate impact. When focus was on minimizing GHG emissions, both traits were equally important on each level of efficiency. To substantially reduce GHG emissions from dairy production,a combination of strategies is required. This book offers an introduction to the microbes and microbial activity of the rumen. Sun, L. L.
