Assessing amino acid uptake and metabolism in mammary glands of lactating dairy cows intravenously infused with methionine, lysine, and histidine or leucine and isoleucine [Appendix]
(2020-12-02)The objective of this study was to evaluate the effect of jugular infusions of 2 groups of AA on essential AA (EAA) transport and metabolism by mammary glands. Four Holstein cows in second lactation (66 ± 10 days in milk) ... -
Contributions of dairy products to environmental impacts and nutritional supplies from United States agriculture
(2020-11-01)Questions regarding the balance between the contribution to human nutrition and the environmental impact of livestock food products rarely evaluate specific species or how to accomplish the recommended depopulation. The ... -
Inter-Comparison of Gauge-Based Gridded Data, Reanalysis and Satellite Precipitation Product with an Emphasis on Hydrological Modeling
(MDPI, 2020-11-20)Precipitation is essential for modeling the hydrologic behavior of watersheds. There exist multiple precipitation products of different sources and precision. We evaluate the influence of different precipitation product ... -
Using Owner Return as a Reinforcer to Operantly Treat Separation-Related Problem Behavior in Dogs
(2020-07)Separation-related problem behavior in dogs is a challenging behavioral issue, often manifesting as destructive behavior or excessive vocalization when the dog is left alone. More knowledge is needed on effective treatments. ... -
What’s in Your Water? Development and Evaluation of the Virginia Household Water Quality Program and Virginia Master Well Owner Network
(Mississippi State University, 2016)Approximately one-fifth of Virginians (about 1.7 million people) rely on private water supplies (e.g., wells, springs, cisterns) for their household water. Unlike public water systems, the Environmental Protection Agency ... -
Local persistence of novel regional variants of La Crosse virus in the Northeast USA
(2020-11-11)Abstract Background La Crosse virus (LACV) (genus Orthobunyavirus, family Peribunyaviridae) is a mosquito-borne virus that causes pediatric encephalitis and accounts for 50–150 human cases annually in the USA. Human cases ... -

Endophytic Burkholderia sp. SSG as a potential biofertilizer promoting boxwood growth
(2020-07-16)Background. Burkholderia sp. SSG is a bacterial endophyte isolated from boxwood leaves showing a resistant response to infection by the boxwood blight pathogen Calonectria pseudonaviculata. SSG acted as a protective and ... -
Changes in Non-Nutritive Sweetener Consumption Patterns in Response to a Sugar-Sweetened Beverage Reduction Intervention
(MDPI, 2020-11-08)Data are lacking on whether non-nutritive sweeteners (NNS) can be used as a strategy to support decreases in sugar-sweetened beverage (SSB) consumption. The purpose of this secondary analysis of a 6-month SSB-reduction ... -
