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

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

Key messages

• 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.
