Seed viability of feathertop Rhodes grass (Chloris virgata Sw.) affected by sheep rumen digestion

Abstract

Key findings • Feathertop Rhodes grass seed viability was reduced by more than 99% after feeding through sheep. • A low level of viable seeds (<1%) can still be detected 12 days after feeding, therefore, if sheep graze feathertop Rhodes grass, they should be quarantined for at least 8 days in order to prevent seed spread.
