An assessment of the ability of the stay-green phenotype in lolium species to provide an improved protein supply for ruminants.

The stay-green phenotype results from a naturally occurring mutation in which senescent leaves retain their chlorophyll and the associated apoprotein, LHCPII. Protection of this protein pool could deliver grass with enhanced protein content and could decrease the extent of protein degradation by plant proteases in the rumen. This would enhance the… CONTINUE READING
