7
Q
Nutritients/antinutritients in:
- Grasses
- Fabaceous plants
- Sour grasses
- Weeds
A
- Lower protein, higher carb., fiber depends on growing stage.
- Higher protein, Ca, P, vitamines. Antinutritive substances (cyanide, estrogenic substances, photosensitization).
- High fibre, silica->sharp leaves->mechanical damage. Low P, Ca, CH.
- a)Poisonous plants b)Stinging plants (sharp structures)
8
Q
What is grass teteny?
A
Deficiency of magnezium (and calcium)
- Low level in early spring – adding salts
- Slow habituation
