For this, a 50-fold dilution of samples and SCFA calibration standards was made. Deuterated SCFA (acetic, propionic, butyric, and valeric acid) were added as internal standards. Sample/internal ...

Figure 4 shows that compared with CON and ANT groups, adding IMO in broiler diet can significantly increase the content of valeric acid (p < 0.05). LC, YD, ZS, HZ, and XH designed the experiment and ...

Standing five feet away, I could smell it in the air. Acrid, damp, toe-curling—a memory from my past. The nose is a powerful historian, so it took only a few seconds to place it: the stench of the rat ...
