Procedures to maintain sheep identification
-
Whenever you give a sheep a new eartag, record any other tag
numbers that the sheep has along with the new eartag number. A
clipboard with forms for this is in the break room.
-
All sheep must have at least two eartags. If you catch
a sheep with only one tag, give it at least one more (two,
if using paired metal tags).
-
Dorsets must have at least one metal tag with the correct
letter for the flock and have one plastic tag of the appropriate
color. If you catch a Dorset sheep without a plastic tag, give
it one of a color that corresponds with the letter of the metal
tag (see above). If you catch a Dorset without a metal
tag, give it a set of metal tags with the letter prefix corresponding
to the color of the plastic tag.
-
Crossbreds should have two tags.
-
Sheep found without any eartags automatically enter the crossbred
flock, even if they are obviously Dorset or Finnsheep. If
you catch a sheep without any eartags, give it a matched pair
of CXB metal tags.
-
More than 200 crossbred ewes are in the Johne's vaccination
trial. They must each have a roundish, purple, plastic
tag as well as at least one metal tag. If you catch a
crossbred sheep with a metal tag with a recent number (FDX
or CXB tags) or with a small, rectangular, pink tag, and if
it looks like it could be missing a plastic tag, check the
database or the JVT Trial Clipboard in the break room to see
if it is in the Johne's vaccination trial. If so, give
it another octagonal, purple, plastic tag and record the new
tag.
