Correlation1 among carbon dioxide, growth, and feed efficiency traits in BIN steers
| Trait | ADG2 | FCR2 | RFI2 |
|---|---|---|---|
| Body weight (BW) | 0.43 | 0.18 | −0.01 |
| Dry matter intake (DMI) | 0.59 | 0.30 | 0.66 |
| Carbon dioxide production rate (CPR) | 0.59 | −0.01 | 0.16 |
| Carbon dioxide yield (CY) | −0.09 | −0.40 | −0.67 |
| Carbon dioxide intensity (CI) | 0.30 | −0.24 | 0.24 |
| Carbon dioxide to gain ratio (CGR) | −0.66 | 0.73 | 0.02 |
| Residual carbon dioxide production from DMI (RCPD) | 0.28 | −0.31 | −0.38 |
| Residual carbon dioxide production from BW (RCPB) | 0.42 | −0.22 | 0.28 |
| Residual carbon dioxide production from MBW3 (RCPM) | 0.42 | −0.21 | 0.28 |
| Residual carbon dioxide production from MBW3 and ADG (RCPMA) | −0.01 | 0.15 | 0.27 |
1Correlation coefficients with absolute values greater than 0.11 are significantly (P < 0.05) different from zero.
2ADG, FCR, and RFI denote average daily gain, feed conversion ratio, and residual feed intake, respectively.
3MBW = Metabolic body weight.
