  • What's the first sheep that was imported from?
    Merino - from Spain via Australia
  • What was the first breed to be developed?
    Corriedale - was a stabilized cross between Merino and several English breeds
  • What was the primary export function for most of sheep production history? What is it now?
    Wool, meat
  • What are the animal welfare reasons to harvest wool?
    Fly strike, heat, weight of fleece, welfare requires annual shearing
  • Lambs are born in Spring from matings which occur the previous Autumn
  • What's a ewes gestation length?
    ~145-150 days
  • Lamb only comes from sheep which have not erupted their first adult incisors (at around 1 year of age). Therefore, lambs will have been slaughtered or be two-tooths by June the following year.
  • In sheep the major income is from lamb sales, therefore efficiency and profit is determined by:
    Number of lambs born alive, number of lambs weaned, growth rates of lambs, mature weight of ewe
  • As lambs grow faster, they'll consume less herbage in total. How?
    Increasing growth rate causes dilution of maintenance, feed costs decrease associated operating costs as well
  • What are some benefits to faster growing lambs if they're going to slaughter?
    Lower feed requirements if destined for slaughter, reduced time on farm before slaughter, less labor requirements
  • What are some benefits to faster growing lambs if they're to be replacement ewes?
    Easier breeding as a hogget, allows some some flexibility in the growth curve later on in the season
  • What increases farm income?
    Increasing lambing percentage/weight
  • What decreases farm income?
    Increasing lamb growth rates
  • At higher lambing percentages the impact of increased weaning weights is greater than an additional increase in lambing percentages
