  1. On the analysis of Canadian Holstein dairy cow lactation curves using standard growth functions

    Journal of Dairy Science 98(4):2701 (2015) PMID 25648814

    Six classical growth functions (monomolecular, Schumacher, Gompertz, logistic, Richards, and Morgan) were fitted to individual and average (by parity) cumulative milk production curves of Canadian Holstein dairy cows. The data analyzed consisted of approximately 91,000 daily milk yield...
  2. Microfiltration: Effect of retentate protein concentration on limiting flux and serum protein removal with 4-mm-channel ceramic microfiltration membranes

    Journal of Dairy Science 98(4):2234 (2015) PMID 25682139

    The objective of our study was to determine if the limiting flux and serum protein (SP) removal were different at 8, 9, or 10% true protein (TP) in the microfiltration (MF) retentate recirculation loop using 0.1-µm ceramic graded permeability membranes with 4-mm-channel diameters opera...
  3. Social influences on the duration of antibiotic treatment of clinical mastitis in dairy cows

    Journal of Dairy Science 98(4):2369 (2015) PMID 25682148

    Clinical mastitis of dairy cows is a visible inflammation of the udder, which is usually caused by bacteria and treated with antibiotics. Although pressure is increasing to reduce antibiotic usage in livestock in the European Union, feedback from the field suggests that clinical mastit...
  4. Short communication: Difructose anhydride III promotes calcium absorption from the duodenum in cattle

    Journal of Dairy Science 98(4):2533 (2015) PMID 25648815

    Difructose anhydride (DFA) III promotes the intestinal absorption of calcium via a paracellular pathway in rats. In dairy cows, DFA III reaches the duodenum without being degraded by ruminal bacteria and hence could be used to control hypocalcemia. The aims of the present study were to...
  5. Inferring causal relationships between reproductive and metabolic health disorders and production traits in first-lactation US Holsteins using recursive models

    Journal of Dairy Science 98(4):2713 (2015) PMID 25622875

    Health disorders in dairy cows have a substantial effect on the profitability of a dairy enterprise because of loss in milk sales, culling of unhealthy cows, and replacement costs. Complex relationships exist between health disorders and production traits. Understanding the causal stru...
  6. Phenotypic and genetic associations of milk traits with milk coagulation properties

    Journal of Dairy Science 98(4):2079 (2015) PMID 25682130

    The aim of this study was to examine milk composition and rennet-induced coagulation properties of milk from 892 individual Danish Holstein and Danish Jersey cows and determine the genetic influences on these properties by determining heritability and genomic correlations with single n...

  8. A rapid HPLC method for indirect quantification of β-lactamase activity in milk

    Journal of Dairy Science 98(4):2197 (2015) PMID 25660746

    To circumvent the strictly regulated limits of antibiotics in milk, illegal addition of β-lactamase to lower the antibiotic levels in milk has been reported recently in China. Herein, we describe a fast, sensitive, and robust HPLC-UV method for the determination of β-lactamase activity...
  9. Effects of whole-plant corn silage hybrid type on intake, digestion, ruminal fermentation, and lactation performance by dairy cows through a meta-analysis

    Journal of Dairy Science 98(4):2662 (2015) PMID 25648819

    Understanding the effect of whole-plant corn silage (WPCS) hybrids in dairy cattle diets may allow for better decisions on hybrid selection by dairy producers, as well as indicate potential strategies for the seed corn industry with regard to WPCS hybrids. Therefore, the objective of t...
  10. Estimating organic, local, and other price premiums in the Hawaii fluid milk market

    Journal of Dairy Science 98(4):2824 (2015) PMID 25704978

    With retail scanner data, we applied hedonic price modeling to explore price premiums for organic, local, and other product attributes of fluid milk in Hawaii. Within the context of revealed preference, this analysis of organic and local attributes, under a single unified framework, is...
