 NOTE for Guideline for Anthelmintic Dosages in Goats

 The attached chart was developed by Ray M. Kaplan, DVM, PhD (University of Georgia) and modified by Patty Scharko DVM, MPH (University of Kentucky.)  It is provided as a possible guideline for anthelmintic (deworming) dosages for goats.  Producers should consult their veterinarian for advice on their specific management situation for determining dosages for their herd.    With the exception of fenbendazole administered at the 5 mg/kg dose, these drugs are not approved by the Food and Drug Administration (FDA) for use in goats, and when used in goats are considered extra label use (fenbendazole at the recommended dose rate of 10 mg/kg is considered extra-label usage).  The FDA regards extra-label use of drugs as an exclusive privilege of the veterinary profession and is only permitted when a bona fide veterinarian-client-patient relationship exists and an appropriate medical diagnosis has been made.  The following chart is intended to serve as guideline for improving accuracy when dosing goats with an anthelmintic, but these drugs should be used in goats only when appropriate veterinary advice has been received.

 Drug resistance in parasites of goats is extremely common. The effectiveness of an anthelmintic should always be tested before being used by performing a FECRT (Fecal Egg Count Reduction test) or larval development (DrenchRite) assay if available.

 ** The current recommendation is to use the Cydectin cattle injectable formulation and NOT the pour-on formulation (orally) or the sheep oral drench. When administered by subcutaneous injection, moxidectin provides improved drug levels as compared to when administered orally.

[1] Valbazen Suspension (11.36 % or 113.6 mg/ml): Do NOT use in pregnant does in the first trimester of pregnancy.  Meat withdrawal time is 9 days and 7 days for milk (FARAD).

[2] Safe-Guard/ Panacur Suspension (10% or 100 mg/ml): Approved in goats at 5 mg/kg with meat withdrawal time of 6 days and no withdrawal period for milk. Although the label dose in goats is 5 mg/kg, it is generally recognized that 10 mg/kg dosage is required for good efficacy. At 10 mg/kg dosage, meat withdrawal is 16 days and 4 days for milk (FARAD).

[3] Ivomec Sheep Drench (0.08% or 0.8 mg/ml): Protect from light. Coughing may occur during and following drenching. Meat withdrawal time is 14 days (FARAD).

[4] Levasole Soluble Drench Powder (Sheep): Oral solution ONLY. To prepare use 1 packet (13 gm/11.7 gm active ingredient) dissolved in 262 ml water (44.7 mg/ml) {or 52 gram packet dissolved in 1048 ml water.}  NOTE: This is different dilution from the label directions for administration.  Meat withdrawal time is 4 days (FARAD).

[5] Cydectin Injectable for cattle (10mg/ml): GIVE SQ. Meat withdrawal time is 30 days. Not for use in lactating dairy goats.
