Article Synopsis
- - The study compared two levels of forage allowance (high and low) for prepartum beef cows to assess their impact on metabolic, hormonal, productive, and reproductive variables, involving 40 primiparous (first-time mothers) and 42 multiparous (having had multiple births) cows.
- - High forage allowance improved cows' intake, energy balance, and body condition, leading to increased milk yield (5.4 kg/d vs. 4.6 kg/d) and higher calf growth rates (0.88 kg/d vs. 0.82 kg/d) compared to low forage allowance.
- - Results indicated that higher forage allowances led to better pregnancy rates (40% vs. 28%) and highlighted
This experiment was to evaluate a suite of biological traits likely to be associated with genetic variation in residual feed intake (RFI) in Angus cattle. Twenty nine steers and 30 heifers bred to be divergent in postweaning RFI (RFIp) and that differed in midparent RFIp-EBV (RFIp-EBVmp) by more than 2 kg DMI/d were used in this study. A 1-unit (1 kg DM/d) decrease in RFIp-EBVmp was accompanied by a 0.

The study was conducted on a single farm with samples taken on 3 days during the spring of 2007. Four anatomical hide sites (perineum area, flank, back, and shoulder) of 10 steers were individually swabbed each sampling day at the farm environment (n = 120).
