Questions

Question 1. What is the difference between resistance and resilience to worms?

Sheep that are resistant to worms can prevent some or all worms from establishing and as a result have lower worm egg counts. Resistance can be readily bred into stock by selecting rams with lower WEC ASBV. Sheep that are resilient to worms can grow and produce with less ill effects from worms.  Resilience is not able to be directly selected, but by choosing better performing sheep this indirectly selects for resistance.

Question 2. Name a factor that affects louse numbers to drop?

Shearing directly removes 30–50% of lice and many more die subsequently because of exposure to environmental influences. Louse numbers are lowest 30­–60 days after shearing, but an effective chemical treatment will still be needed to eradicate lice completely.

Question 3. Do you know five recommended steps to treat fly struck sheep?
  1. Shear struck wool and a 5 cm barrier of clean wool around the strike close to the skin to remove maggots

  2. Collect the maggot-infested wool into a maggot-proof (plastic) bag and leave the bag in the sun for a couple of days to kill all maggots

  3. Apply a registered flystrike dressing to the shorn area to prevent re-strike

  4. Remove struck sheep from the mob

  5. Cull struck sheep from breeding programs

Question 4. Worms (internal parasites) are currently estimated to cost the Australian goat industry: a. $100,000 per year b. $1 million per year c. $2.5 million per year

$2.5 million per year across the industry, though an individual farm following the WormBoss program could be saving up to $5 per ewe per year.
