It grows in all types of soil, especially sandy soil and fertile soil.
It is found in disturbed places such as road reserves, gardens and cultivated lands.
General: A short, mat-forming perennial grass, which spreads by means of slender stolons and rhizomes. It is a pioneer that will grow on bare soil and begin to rebuild the soil in disturbed places.
Leaves: The leaves point upwards.
Flowers: The inflorescence consists of 4 - 7 digitately arranged racemes and the spikelets are flat and without awns. September - May.
• One possiblity is that ergot-infected seedheads (Claviceps cynodontis)
could be responsible for the kweek tremors.
• Another possibility is that an endophyte may produce tremorgenic mycotoxins.
Kweek tremors, ABPE (Acute Bovine Pulmonary Oedema and Emphysema).
Central nervous and respiratory systems.
Kweek tremors have been observed in calves and sheep that have been grazing in pastures of predominantly Cynodon dactylon. Latent period of 1-2 days. Stimulation and exertion (exercise) often precipitate signs.
All stages of nervous derangement seen from:
• Mild involuntary trembling to spastic tremors of individual muscle groups
• Nodding of head, shaking of limbs or trunk
- stiff-legged gait,
- side-ways progression,
- falling and inability to get up to complete prostration (recumbency)
Some cases show hypersensitivity and paddling movements like heartwater. Adopt position of sternal recumbency.
• Except for outspoken cases, animals remain alert and retain their appetites.
• When withdrawn from infected pastures recover rapidly over a few days.
• Usually a non-fatal syndrome.
• Nothing specific
• For ABPE return to ABPE file
• Remove from infected pasture and allow recovery.
