Undi, M., Wilson, C., Ominski, K. H. and Wittenberg, K. M. 2008. Comparison of techniques for estimation of forage dry matter intake by grazing beef cattle. Can. J. Anim. Sci. 88: 693 701. Four techniques were compared for their ability to estimate forage dry matter intake (DMI) of grazing animals. In the Cage technique, 10 grazing cages were placed within each pasture, and forage inside and ou...

tidepressants that are widely used clinically. As shown in Fig. 1, IMI is oxidized by cytochrome P450 (CYP) mainly via two pathways: side-chain N-demethylation and aromatic ring 2-hydroxylation, forming DMI and 2-hydroxyimipramine (2OH-IMI), respectively. DMI and 2-OH-IMI further undergo 2-hydroxylation and N-demethylation, respectively, forming 2-hydroxy-DMI as the common metabolite (Fig. 1). ...

A simulation technique involving 100 hypothetical experiments (24 pens each for control and treated groups) for each of 3 cases was used to evaluate the statistical sensitivity of dietary NE concentrations calculated from performance data. In case 1, the treated population had a 12-kg increase in mean shrunk final BW (FBW) and no change in DMI; in case 2, the treated population had a 19-kg incr...

Previous results suggest that extracellular dopamine (DA) in the rat cerebral cortex originates from dopaminergic and noradrenergic terminals. To further clarify this issue, dialysate DA, dihydroxyphenylacetic acid (DOPAC) and noradrenaline (NA) were measured both in the medial prefrontal cortex (mPFC) and in the occipital cortex (OCC), with dense and scarce dopaminergic projections, respective...

Background Patient-reported outcomes are important measures when assessing the efficacy of aesthetic procedures. Objective To compare outcomes between 2 volumizing hyaluronic acid fillers. Materials and Methods Subjects with moderate-to-severe volume loss in the cheeks were randomized in a split-face design to malar enhancement with Cohesive Polydensified Matrix 26 mg/ml HA (CPM-26) and Vyc...

The present study was conducted to study the effect of protected-glutamine (Gln) supplementation on dry matter intake (DMI), milk yield (MY) and composition, somatic cell counts (SCC) and blood parameters in fresh cows. Forty Holstein cows at zero day of parturition (calving day = day 0) were divided into four groups (n=10), and fed (ad libitum) with one of the diets including: basal d...

To examine the effect of trace mineral (TM) status and TM injection on growth performance and carcass characteristics in beef cattle, 40 steers were used in a growing and finishing study. Steers were stratified by weight (323 ± 14.8 kg) and assigned to 1 of 2 treatments for an 84-d depletion period: 1) a corn silage-based diet supplemented with Cu, Mn, Se, and Zn to meet or exceed NRC recommend...
