Calves must always be needled in the neck when giving an
intramuscular injection, as the neck is the least expensive cut of
veal. When needling in the hind you are damaging the most expensive
cut of veal.
Never give more than 10cc of any medication at any one-injection
site. If you have the option to give a medication subcutaneously,
that should always be the route of choice as there will be less
tissue damage. It is estimated that on average, more than $9.00
worth of trim per carcass marketed in Canada is removed because of
injection site lesions. One injection in the hind could result in a
fist size pocket of pus.
Choosing the correct needle size and length is very important for
proper entry and safety to the animal. Needles should be changed
every 10 to 15 injections unless they are bent or dull – then they
need to be changed immediately. For a subcutaneous (SQ) injection,
a 16 or 18-gauge needle, ½ or ¾” long is most appropriate.
For an intramuscular (IM) injection, an appropriate needle and
length would be also 16 or 18 gauge, but 1 to 1 ½“long. Fourteen
gauge needles are not recommended because the injection would cause
too much pain to the calf.
Vaccines and antibiotics are the most commonly used medications
on veal farms. Most products have labels and package inserts, which
describe the medication, the reasons for its use, its dosage, method
of storage, and withdrawal time. A list of all medication approved
for use in veal calves is included in the Veal Medication appendix
of this manual. Some have withdrawal times as long as 60 days. |
