afs-6702	Misselbrook, Tom; Del Prado, Agustin; Chadwick, David	Opportunities for reducing environmental emissions from forage-based dairy farms	2013	15	.pdf	application/pdf	11660	572	49	For medium and extensive systems, enteric CH4 was reduced through a higher starch to fibre concentration in the diet (e.g. Beauchemin et al. 2008, Cottle et al. 2011), but soil N2O emissions were increased mainly caused by the replace- ment of grass with forage maize and the changes in manure application rates and timing. Wall et al. (2010) discuss the use of genetic selection tools for breeding schemes with the aims of improving productivity and efficiency and, potentially, selecting for inherently low CH4 emitting animals, although it is important that this selection is on the basis of multiple traits including feed efficiency, particularly for predominantly forage-fed animals, and yield to ensure that gains are realised as reduced emissions per unit product.	cache/afs-6702.pdf	txt/afs-6702.txt
