The effects of feeding a quebracho-chestnut tannin extract mixture on performance and nitrogen (N) utilization were assessed with 36 multiparous lactating Holstein cows (mean ± standard deviation; 706 ± 59 kg of body weight; 126 ± 20 d in milk) ra

Tools necessary for quantum simulations of $1+1$ dimensional quantum chromodynamics are developed. When formulated in axial gauge and with two flavors of quarks, this system requires 12 qubits per spatial site with the gauge fields included via non-l

The objective of this study was to determine the relative partitioning of N in individual feed within a diet (alfalfa silage [AS], corn silage [CS], corn grain [CG] and soybean meal [SBM]) into milk, urinary and fecal N in lactating dairy cows. For 1
