  7. Comparison of rumination activity measured using rumination collars against direct visual observations and analysis of video recordings of dairy cows in commercial farm environments

    Journal of Dairy Science 98(3):1750 (2015) PMID 25622871

    Automated systems for monitoring the behavior of cows have become increasingly important for management routines and for monitoring health and welfare. In the past few decades, various devices that record rumination have been developed. The aim of the present study was to compare rumin...
  8. Hyperketonemia in early lactation dairy cattle: A deterministic estimate of component and total cost per case

    Journal of Dairy Science 98(3):2043 (2015) PMID 25622874

    The purpose of this study was to develop a deterministic economic model to estimate the costs associated with (1) the component cost per case of hyperketonemia (HYK) and (2) the total cost per case of HYK when accounting for costs related to HYK-attributed diseases. Data from current l...
  9. Reductions in milk Δ9-desaturation ratios to oral dosing of cobalt-acetate are accompanied by the downregulation of SCD1 in lactating ewes

    Journal of Dairy Science 98(3):1961 (2015) PMID 25547303

    Oral administration of cobalt has been proven to alter milk fatty acid (FA) composition consistent with an inhibition of mammary stearoyl-coenzyme A desaturase (SCD) activity in ruminants, but the mechanisms explaining its mode of action remain uncertain. In this study, Co (as Co-aceta...
  10. Milk production responses to dietary stearic acid vary by production level in dairy cattle

    Journal of Dairy Science 98(3):1938 (2015) PMID 25529423

    Effects of stearic acid supplementation on feed intake and metabolic and production responses of dairy cows with a wide range of milk production (32.2 to 64.4kg/d) were evaluated in a crossover design experiment with a covariate period. Thirty-two multiparous Holstein cows (142±55 d in...
