Interpretive Summary: New Techniques Improve Agricultural Research. There is a growing concern over the effects of livestock production on the environment. Scientists continue to adapt new technologies into their research programs. Scientists from USDA-ARS (Bushland, Texas), Texas A and M AgriLife Research (Amarillo, Texas), and New Mexico State University (Las Cruces, New Mexico) have summarized the existing technologies used for conducting research on the environmental impacts of feeding beef cattle. These technologies include methods for measuring feed intake and methane emissions from individual animals, measuring greenhouse gas and ammonia emissions from manure, and identifying potential pathogens in manure. New technologies must be validated for accuracy.
Technical Abstract: With increased concern over the effects of livestock production on the environment, a number of new technologies have evolved to help scientists evaluate the environmental footprint of beef cattle. The objective of this review was to provide an overview of some of those techniques. These techniques include methods to measure individual feed intake, enteric methane emissions, ground level greenhouse gas and ammonia emissions, feedlot and pasture emissions and identify potential pathogens. The appropriate method to use for measuring emissions will vary depending upon the type of emissions, the emission source, and the goals of the research. These methods should also be validated to assure they produce accurate results and achieve the goals of the research project. In addition, we must not forget to properly use existing technologies and methods such as proper feed mixing, feeding management, feed/ingredient sampling, and nutrient analysis.
