farm flock vs. range flock breeds
FARM FLOCK:
Dorset
Suffolk

RANGE FLOCK:
Rambouillet
Rambouillet
cream - white, wool on legs
rams usually horned
closed faces
large (rams ~300 lbs)

STRONG:
flocking instincts
hardy
fine wool
longevity

WEAK:

medium staple length
Dorset
white color, wool on legs (shorter than Rambouillet)

medium size (rams ~250lbs)
good mutton type

Finnsheep
(from Finland)
white, no wool on face and legs. small to medium size
medium wool and staple length (3-5 in). poor carcass, frail. very prolific (avg. 2.5 lambs) early puberty, easy lambing. mainly used in crossbreeding programs
Romanov
imported to improve genetics. because...
early sexual maturity - fertile by 7 mos old.
prolific - typical 4-5 lambs
ewes breed any month
wanted for high fertility
Textel
imported for:
amt of muscle and high lean-tofat ratio.
small amt of intermuscular fat
high lamb survival rates. for increased muscling leanness in crossbreeding
how to hold a sheep
left hand under chin
right hand holding dock or flank
catching a sheep
NEVER pull by their wool. will bruise muscles - carcass damaged. grabbing wool separates the "fell" from muscle
