Three monensin levels during a stocker phase (0, 800, 1600 g/ton in a free choice mineral) and two levels during finishing (0 [U] or 37.5 mg/kg diet DM [M]) were used to determine the effects of monensin supplementation during a stocker and subsequent finishing phase on beef calves. Steers (n = 605, BW = 278 ± 27 kg) were fed pearl millet hay with soybean hull and corn gluten feed supplement (0.5% BW daily [AF basis] Block 1) or grazed fall wheat (Block 2), spring wheat (Block 3), bermudagrass (Blocks 4 & 5) or wheat with mixed-grass baleage (Block 6). …

Background: Improving feed efficiency (FE) of pigs by genetic selection is of economic and environmental significance. An increasingly accepted measure of feed efficiency is residual feed intake (RFI). Currently, the molecular mechanisms underlying RFI are largely unknown. Additionally, to incorporate RFI into animal breeding programs, feed intake must be recorded on individual pigs, which is costly and time-consuming. Thus, convenient and predictive biomarkers for RFI that can be measured at an early age are greatly desired. In this study, we aimed to explore whether differences exist in the global gene expression profiles of peripheral blood of 35 to 42 day-old …
