Magnesium Bioavailability Update
What have we learned about magnesium nutrition in animals during the past few years? Several research reports have been published which increase our understanding of Mg utilization. While an earlier generation of researchers concentrated more of their efforts on solving the grass tetany problem, recent research has emphasized the areas of absorption, bioavailability of Mg sources, the effects of ...

Agricultural Manure Drying Machine for Cows
Manure drying machines are utilized in agricultural settings to remove moisture from wet manure. The drying process breaks down manure, kills bacteria and creates pathogen-free bedding. The drying process also cuts down on storing and disposing of bulk manure and the costs associated with both activities. Dried Manure Solids (DMS) can be used as bedding for the dairy industry. A lactating ...

Pressure Measurement For Agricultural Applications
A couple months ago we took a brief look at how the agriculture industry is turning to automation and data to help monitor product and resource levels, enabling farmers and ranchers to be proactive, rather reactive, about the needs and conditions of their businesses. We all agreed that there are plenty of opportunities for level measurement in the modern agriculture industry. But what of ...

Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows
Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

Effects of reducing dietary nitrogen on ammonia emissions from manure on the floor of a naturally ventilated free stall dairy barn at low (0–20°C) temperatures
Received for publication December 30, 2008. This study was conducted to determine the potential for reducing ammonia (NH3) emissions from manure deposited on the floor of a naturally ventilated free stall barn by mid-lactation dairy cows fed reduced or normal N diets. Two crude protein (CP) diets (178 g kg–1 [high] and 159 g kg–1 [low] dry matter ), were used. The diets were fed to 48 Holstein ...
