  1. The effects of postexercise consumption of a kefir beverage on performance and recovery during intensive endurance training

    Journal of Dairy Science 98(11):7446 (2015) PMID 26298752

    This study was designed to determine whether kefir accentuates the positive health benefits assessed by measures in fitness, body composition, or both, as a measure of cardiovascular disease risk as well as the biomarker C-reactive protein (CRP). Sixty-seven adult males and females age...
  2. Maternal consumption of organic trace minerals alters calf systemic and neutrophil mRNA and microRNA indicators of inflammation and oxidative stress

    Journal of Dairy Science 98(11):7717 (2015) PMID 26319761

    Organic trace mineral (ORG) supplementation to dairy cows in substitution of sulfate (INO) sources has been associated with improvement in immune function during stressful states such as the peripartal period. However, the effect of supplemental ORG during pregnancy on the neonatal cal...
  3. Survey of facility and management characteristics of large, Upper Midwest dairy herds clustered by Dairy Herd Improvement records

    Journal of Dairy Science 98(11):8245 (2015) PMID 26319764

    A survey of management practices was conducted to investigate potential associations with groupings of herds formed by cluster analysis (CA) of Dairy Herd Improvement (DHI) data of 557 Upper Midwest herds of 200 cows or greater. Differences in herd management practices were identified ...
  4. Effects of intramuscular administration of folic acid and vitamin B12 on granulosa cells gene expression in postpartum dairy cows

    Journal of Dairy Science 98(11):7797 (2015) PMID 26298749

    The fertility of dairy cows is challenged during early lactation, and better nutritional strategies need to be developed to address this issue. Combined supplementation of folic acid and vitamin B12 improve energy metabolism in the dairy cow during early lactation. Therefore, the prese...
  5. Treatment of grain with organic acids at 2 different dietary phosphorus levels modulates ruminal microbial community structure and fermentation patterns in vitro

    Journal of Dairy Science 98(11):8107 (2015) PMID 26299164

    Recent data indicate positive effects of treating grain with citric (CAc) or lactic acid (LAc) on the hydrolysis of phytate phosphorus (P) and fermentation products of the grain. This study used a semicontinuous rumen simulation technique to evaluate the effects of processing of barley...
  6. Production parameters of autumn-calving cows offered either a total mixed ration or grazed grass plus concentrate during early lactation

    Journal of Dairy Science 98(11):7917 (2015) PMID 26342978

    The objective of this experiment was to measure the milk yield and composition from cows offered a total mixed ration (TMR) compared with those grazing grass and offered different quantities of concentrates during the first 6wk of lactation when the experimental diets were offered, and...
  7. Suspension of milking in dairy cows produces a transient increase in milk lactoferrin concentration and yield after resumption of milking

    Journal of Dairy Science 98(11):7823 (2015) PMID 26319762

    Lactoferrin is a multifunctional glycoprotein with a range of antimicrobial and immune-related properties that is found at >10-fold higher concentration in human milk (~1.7g/L) relative to bovine milk (~0.15g/L). Consumer demand is increasing for bovine lactoferrin through a wide range...
  8. Effect of forage level and replacing canola meal with dry distillers grains with solubles in precision-fed heifer diets: Digestibility and rumen fermentation

    Journal of Dairy Science 98(11):8054 (2015) PMID 26299163

    Objectives of this study were to determine the effects of feeding differing forage-to-concentrate ratios (F:C) and inclusion rates of corn dry distillers grain with solubles (DDGS) on digestion and rumen fermentation in precision-fed dairy heifer rations. A split-plot design with F:C a...
  9. Modification of the Kjeldahl noncasein nitrogen method to include bovine milk concentrates and milks from other species

    Journal of Dairy Science 98(11):7510 (2015) PMID 26298747

    The objective of our research was to modify the current indirect casein method for bovine milk to enable it to be applied to bovine milk, bovine milk concentrates, and milks of other species that contain a protein concentration up to 9% (wt/wt). Our work used a series of bovine milk co...
  10. Risk factors for the occurrence of new and chronic cases of subclinical mastitis in dairy herds in southern Brazil

    Journal of Dairy Science 98(11):7675 (2015) PMID 26298754

    The aim of this research was to evaluate the risk factors for new and chronic subclinical intramammary infections (IMI) using the monthly somatic cells count of dairy cows. The study took place at 30 dairy herds with approximately 1,700 cows in lactation. Data characterizing the dairy ...
