Real Science ExchangeEstimation of the nutrient variation in feed delivery and impacts on lactating dairy cattle with Dr. Paul Kononoff, University of Nebraska-Lincoln and Dr. Bill Weiss, The Ohio State University Professor EmeritusDr. Kononoff’s lab evaluated retrospective feed mixing records collected from eight commercial dairy farms. Data was divided into 28-day periods. Daily TMR nutrient deviation was automatically calculated from feed mixer data as the actual amount of a nutrient fed minus the target amount from the original diet formulation, divided by the target amount. (5:43)Crude protein, NDF, fat, and starch were the nutrients evaluated in the study. (13:40)Variation was positive for every nutrient on the vast majority of days. Dr. Kononoff attributes that to more feed being delivered than the diet formulation predicted animals would co...2024-09-2441 minReal Science ExchangeJournal Club Bach Changes in milk production and estimated income over feed cost of group-housed dairy cows when moved between pensGuests: Dr. Alex Bach, ICREA (Catalan Institution for Research and Advanced Studies), and Dr. Bill Weiss, The Ohio State UniversityIn this journal club episode, Dr. Alex Bach with the Catalan Institution for Research and Advanced Studies joins Dr. Bill Weiss from the Ohio State University. Dr. Weiss introduces the paper as one that's immediately applicable to the industry and answers a question he received a lot during his Extension career: What's the cost of moving cows?
