  Daily Rollercoaster of Blood and Milk Metrics 

  McArt, J.A.A.; Barbano, D.M. (2020-10)

  We often measure blood β-hydroxybutyrate and non-esterified fatty acids in early lactation cows to diagnose excessive energy deficit on the individual cow and herd levels. In this presentation, we will discuss diurnal ...

  Milk Urea Nitrogen: Precision, Accuracy, and Individual Animal Variability 

  Reed, K.F.; Wood, E.M.; Portnoy, M.; Barbano, D. (2020-10)

  MUN can be a useful metric for managing diets and assessing environmental impacts but it is difficult to interpret without knowledge of the expected variability or measurement error. I will discuss results from some recent ...

  Update on DCAD for dry and lactating cows 

  Overton, T.R. (2020-10)

  This presentation will update our understanding of the role in dietary cation anion difference (DCAD) in dairy cattle nutrition during both the prepartum and postpartum periods. During the prepartum period, decreasing the ...

  Trimethylamine N-oxide in Humans and Dairy Cows: Should We Be Concerned? 

  McFadden, J.W.; Myers, W.A. (2020-10)

  The gastrointestinal degradation of choline, betaine, and carnitine results in the formation of trimethylamine N-oxide (TMAO) in humans and dairy cows. In humans, TMAO has emerged as an associative biomarker for non-alcoholic ...

  Impact of Starch and Energy on Amino Acid Requirements of Lactating Dairy Cattle 

  LaPierre, P.A.; Fredin, S.; Ross, D.; Van Amburgh, M. (2020-10)

  Improved milk protein output and nitrogen use efficiency have been demonstrated in recent literature where cattle were given greater levels of glucogenic nutrients. This work evaluates this concept using optimal essential ...

  Valuating Nutritive Value of Alfalfa with Meadow Fescue Varieties for Optimal Quality in Dairy Production Systems 

  Tacoma-Fogal, R. (2020-10)

  Dairy forage production in New York State is unique because over 85% of alfalfa sown in the state is done in combination with a perennial grass. Introducing a grass species into the alfalfa (Medicago sativa L.) stand can ...

  Association Between Haptoglobin and Cow and Herd Level Outcomes 

  Kerwin, A.L.; Overton, T.R. (2020-10)

  Haptoglobin is an inflammation marker which is virtually non-existent in healthy cows but increases over 100-fold at the onset of an inflammation event. Previous studies have reported an association between elevated ...

  Exploratory Analysis of Haylage Quality Variability at Harvest 

  Barrientos-Blanco, J.A.; Reed, K. (2020-10)

  There are many factors during grass and alfalfa production and ensiling that influence variability in haylage quality. Better management of forage quality variability can improve the accuracy and precision of delivering ...
