Data on feed composition, animal characteristics, methane emissions and nitrogen excreta from sheep.
The data will be used to expand on findings from a collaboration between AgResearch and UCDavis in which structural equation modelling (SEM)  techniques have been used to quantify possible trade-off or synergy between traits. As proof of concept, a trade-off analysis of CH4 emissions and N excretion in cattle using a comprehensive database collected over the last 40 years has been conducted and published. 
We would like to explore if the insights gained from the analysis of cattle data apply to sheep fed fresh forages.
Approval to share the data from the following trials is sought:
BRC: initial Brassica study (PGgRc)
CPT21: animal to animal variation study (PGgRc, possibly co-funded by NZAGRC)
FB: fodder beet study (PGgRc/NZAGRC)
gRAP: grazing study with forage rape (SLMACC)
HSG: 'high sugar' grass study (SLMACC)
RAP02: forage rape study (PGgRc/NZAGRC)
SBRC02: summer brassicas study (SLMACC).
