A micellar casein‐alginate blend is wet‐spun into fibers using a calcium‐rich coagulation bath. Fibers with different levels of casein are dried and tested. Swelling tests showed increased stability in decalcifying media with micellar casein. Mechanical properties remained largely unchanged, except after treatment with citric acid, where the breaking ...

ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Abstract Twinning in dairy cattle is an unavoidable outcome of reproduction and is undesirable because it reduces the overall profitability of a dairy operation through negative effects on cows calving twins as well as on calves born as twins. Cows calving twins are at greater risk for many periparturient reproductive and metabolic disorders than ...

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Energy Metabolism of Dairy Cattle
Energy metabolism research during the past 25 yr has resolved many uncertainties of energy use by lactating cows. Use of metabolizable energy for milk production essentially is unaffected by milk yield but is slightly influenced by its source. Estimates of efficiency of use for milk production (60 to 64%) are lower than earlier estimates (69 to 70 ...
