Table 7 Summary of validation research published in the past decade
Authors | Ingredients | BW, kg | Methods | Experimental designa | Conclusion |
|---|---|---|---|---|---|
Wu et al. (2007) [28] | Tallow | 23–98 | Caloric efficiency | Keep the NE to SID Lys ratio constant | The NE efficiency was not influenced by fat level, but DE and ME efficiency decreased |
Eastwood et al. (2009) [51] | Flaxseed meal | 32–115 | Gain to feed ratio | Keep NE and SID Lys constant | The NE of flaxseed meal was correctly estimated |
Montoya et al. (2010) [46] | Canola meal and full-fat canola seeds | 30–60 | Gain to feed ratio | Keep NE and SID Lys constant | The NE of canola meal was correctly estimated, but slightly underestimated for full fat canola seed. |
Adeola et al. (2013) [47] | Soybean oil and tallow | 6–25 | Caloric efficiency | Keep the ME to SID Lys ratio constant | The NE of soybean oil from the 2012 NRC was accurate. NE of tallow were underestimated |
De Jong et al. (2014) [48] | Wheat middlings | Nursery pigs | Caloric efficiency | Keep the SID Lys constant and isocaloric | The INRA NE of wheat midds appears to be a more accurate energy value than the ME obtained from the NRC |
Graham et al. (2014) [39] | Medium-oil corn DDGS | 69–126 | Caloric efficiency | Keep the SID Lys constant and isocaloric | The NE of corn DDGS was accurate |
Nitikanchana et al. (2015) [49] | Medium-oil corn DDGS and fat | 57–124 | Caloric efficiency | Keep the SID Lys constant and isocaloric | The NE of corn DDGS was overestimated and fat was underestimated |
Wu et al. (2016) [52] | 4 corn DDGS sources | 22–115 | NRC growth model; prediction error and bias | Keep NE to SID Lys ratio similar | The NE predicted by a commercial service resulted in suboptimal prediction of NE among corn DDGS sources |
Li et al. (2017) [12] (MAFIC work) | Corn, SBM, rapeseed meal | 36 | Caloric efficiency | Keep NE to SID Lys ratio similar | The NE measured was correctly estimated |
