Contenido: | ABSTRACT.- Potential trade-off among weaning (WWT) and yearling weights (YWT), greasy fleece weight (GWT) genetic resistance to gastrointestinal nematodes assessed by faecal worm egg account (FEC), residual feed intake (RFI) and methane (CH4) and carbon dioxide (CO2) emissions were investigated in 217 Corriedale female lambs. Improving RFI was strongly associated with lower dry matter intake (DMI) and independent of metabolic body weight (MWT) and average daily gain (ADG). Person correlation coefficients were also no significant (P>0.05) with WWT, YWT, GFW and FEC expected progeny differences (EPD). FEC EPD was not correlated with any of the traits investigated here. Both CH4 and CO2 were not associated with RFI, although the moderate correlations with DMI. Higher EPD for WWT, YWT and GFW were correlated with higher DMI, CO2 and CH4. Optimising higher productivity and environmental sustainability requires further research for a more comprehensive understanding of these associations.
