From: Methodologies on estimating the energy requirements for maintenance and determining the net energy contents of feed ingredients in swine: a review of recent work

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
  1. aDE: Digestiable energy; ME: Metabolizable energy; NE: Net energy; SID Lys: Standardized ileal digestible lysine
