Introduction
• This lesson will help you to:– Identify the requirements of a VCPR– Understand the Food and Drug
Administration’s (FDA) requirement prohibiting extra-label use of drugs in medicated feeds
– Explain and understand over-the-counter, prescription, extra-label use and veterinary feed directive drugs

VCPR
• What is needed for a VCPR?– The veterinarian must:
Have assumed the responsibility for making medical judgments regarding the health of the animal(s) and the need for medical treatment
Have working knowledge of the animal and/or operation
Be readily available for follow-up and consultation
– The owner/caretaker of the animal agrees to follow instructions of the veterinarian

VCPR
• Benefits of a VCPR– Your veterinarian will be able to:
Readily follow-up Initiate a preliminary diagnosis
much faster Assist you with withdrawal times
and recordkeeping Provide “extra-label” drug use
when appropriate

VCPR
• Involve your veterinarian
– Regular herd checks
– Timely and accurate diagnosis
6Good Production Practice 2
Medication Use
• Label use– Using an animal health
product exactly as it is stated on the label
7Good Production Practice 2
Medication Use
• Extra-Label– When a veterinarian
changes the medication dosage or any other instruction on the medication label
8Good Production Practice 2
Medication Use
• Extra-Label– Your veterinarian may change:
1. Dosage
2. Frequency of administration
3. Route of administration
4. Duration of treatment
5. Indication or condition treated
6. Species or life stage treated
–No one, not even a veterinarian, can prescribe the extra-label use of a medicated feed

Medication UseExtra-label Use or Label-Use?
The label says to give 5 cc of the drug, your veterinarian says give 10 cc.
Your veterinarian suggests using a drug approved for cattle but not for swine on
your pig.
The label says treat your pig twice a day and you treat it at 8 a.m. and 8 p.m.

Medication Use
• Drug Compounding – – Mixing of two or more drugs to
make a different medication– Compounding can only be done by
your veterinarian and only when you have a VCPR
11Good Production Practice 2
Medication Use
• Medicated feed– Feed containing an animal health product– Must be fed according to the label
• Veterinary Feed Directive (VFD)– Category of antimicrobial drugs delivered
in feed– You cannot buy, store or use VFD
products unless you: Have a valid feed mill license Are a distributor of VFD feeds, or Have a valid VFD issued by your
veterinarian
12Good Production Practice 2
Medication Use
• Medicated Feed Tag– Purpose of the medication– Directions for use– Names and amounts of all active
drug ingredients – Withdrawal period– Warning against misuse
13Good Production Practice 2
Medication Use
• Do not give additional drugs to animals while on medicated feed without veterinarian approval
• Avoid contamination of medicated and non-medicated products
14Good Production Practice 2
Classes of Medication
• Over-the-counter (OTC) – Can be purchased by you from:
veterinary clinics feed or farm supply stores animal health salespeople
• Prescription (Rx) – Only available on order of a
veterinarian

Residue Testing
• When you have a question about withdrawal time, residue testing is necessary!
• Benefits– You keep your good reputation– Testing is lower cost than
the cost of giving the pork industry a bad reputation
– Helps satisfy export market requirements
