- 2. in the first ___ days after shearing greatest risk of hypothermia. Can be vulnerable to summer/autumn unexpected storms. Vulnerability decreases after around 2 weeks. Can put in sheltered paddock/shed or feed out before cold weather.
- 6. _______ season is not a good opton for shearing. Too cold, would hav e to eat more to support, so would have to feed more (but winter is feed limiting time)
- 7. one theory for shearing in winter would be that mothers would find shelter in which to give birth to _____s, thus increasing _____ survival rates. Still not a good idea to shear in winter – mother put more energy into keeping warm rather than pregnancy.
- 10. _________ and strength of wool fibres varies season to season depending on nutrition. Want the skinny bits on the ends and the fat bit in the middle. This coincides wth protein in grass. However, in spring ewes lactating will have weak points. Average over time – no change in staple strength.
- 13. shear merino wool _____ a year, other wool breeds (carpet wool etc) twice a year.
- 14. aim to sell surplus sheep right after shearing, in mid/late _______, before grass runs out. Sell older ewes (cast for age). So autumn shearing time not great from this perspective – have to keep old sheep over feed shortage season _______ until shearing.
- 15. shearing in winter can increase _____ requirement up to 75% more in ewes (non pregnant). Can have a higher stocking rate if not shorn in winter.
- 16. “_____”wool: some months of wool growth
Down
- 1. blowflies active in warm ______ conditions. late spring, early autumn.
- 3. ‘____’ wool: ready to shear
- 4. overall, shearing time may vary because one season doesn’t have ALL the benefits. Overall, either December or _________ shearing is probs the best. Depends on farm, blowfly activity, grass seeds etc.
- 5. _______ strike develops in males into body strike. Due to moisture around ______.
- 8. the main wool length that is at risk of developing fleece rot (major risk for body strike) is not short wool (dries out) or long wool (moisture cant penetrate down to skin) but _______ length wool.
- 9. _________ strike develops due to moisture/feaces and urine around ____ area attracts flies, lay eggs, maggots, dermatitis, septicaemia.
- 11. ______ strike: bacterial infection on skin due to moisture exudates attracts flies lay eggs, maggots irritate skin, severe dermatitis septicaemia.
- 12. merino sheep grow around ___ cm of wool in 12 months
