Digestion Takes Time

David R. Mertens, Ph.D, Mertens Innovations & Research LLC Understanding digestion kinetics is relevant because time and potential extent of digestion are becoming crucial limitations for high-producing animals. When animals produce more, they eat more, and this pushes digesta through the stomach and intestines more rapidly. Faster rates of passage through the digestive tract result in […]

Heat Stress and Forage Feeding Approaches

Rick Grant William H. Miner Agricultural Research Institute Summer’s heat and humidity are just around the corner. We need to be prepared with effective heat abatement systems that will cool our cows and allow them to respond to the diets fed. Unless a cow is properly cooled, adjusting dietary ingredients and feeding highly digestible forages […]

Forage NDFd Variability and the Cow Response

Rick Grant William H. Miner Agricultural Research Institute Chazy, NY 12921 Recently, I was asked the question of whether you should worry about day-to-day variation in forage NDF digestibility. Like any nutrient, NDF and its digestibility may vary across days as the forage inventory is fed out. The important question is whether or not it […]
