  • Science and Industry Work to Improve Phosphorus Management on New York Dairy Farms 

    Chase, L. E.; Reed, K. F. (2020-07-12)
    Phosphorus (P) is a key mineral in dairy cattle rations and farm nutrient management. In the dairy cow, P is essential for bone growth and repair, nerve function muscle contraction and acid-base buffering in blood and the ...
  • Science and Industry Work to Improve Nitrogen Management on New York Dairy Farms 

    Chase, L. E.; Reed, K. F. (2021-05-25)
    Nitrogen (N) is a key nutrient for dairy cattle and is the building block of amino acids and proteins in animals and plants. Nitrogen in feed is either used to support milk and milk protein production or it is excreted via ...
  • Palmitic Acid, Milk Fat, and Hard Butter - What's All of the Fuss About? 

    Overton, Thomas R.; Barbano, David M.; Van Amburgh, Michael E.; McFadden, Joseph W. (2021-03)
    The purpose of this fact sheet is to provide information on how milk fat is synthesized and to provide additional context for the consumer and those involved in the discussion.
  • SAS Code for Technical note: Comparison among three methods for evaluating clinical mastitis frequency in dairy cows: cow-level risk, cow-level rate, and quarter–level rate 

    Alanis, Valeria M.; Tomazi, Tiago; Santisteban, Carlos; Nydam, Daryl V.; Ospina, Paula A. (2020-11-06)
    The lack of standardization in reporting clinical mastitis incidence limits the ability to compare results across multiple studies without additional calculations. There is both a biological and statistical rationale for ...
  • 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 ...
  • 2020 Cornell Nutrition Conference Proceedings 

    Cornell University Department of Animal Science; Harvatine, K.J.; Jenkins, T.; McGee, D.; Place, S.; Ballou, M.; Davis, E.M.; Adesogan, A.T.; Arriola, K. G.; Harvatine, K.J.; Smith, K.M.; Grant, R.J.; Obata, A.; de Ondarza, M.B.; Emanuele, S.M.; Sniffe, C.J.; McArt, J.A.A.; Barbano, D.M.; Elrod, C.C.; Boyd, R.D.; Jackman, J.A.; Miller, M.D.; Tylutki, T.P.; Grant, R.J.; Molano, R.A; Ortega, D.; Drackley, J.K.; James, R.; Van Amburgh, M.E.; Morrison, S.Y.; Fontoura, A.B.P.; McFadden, J.W.; Barrientos-Blanco, J.A.; Reed, K.F.; Kerwin, A.L.; Overton, T.R.; Tacoma-Fogal, R.; LaPierre, P.A.; Fredin, S.; Ross, D.; Van Amburgh, M.E.; McFadden, J.W.; Myers, W.A.; Overton, T.R.; Chase, L.E.; Reed, K.F.; Wood, E.M.; Portnoy, M.; Barbano, D.

  • 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 ...
