Dosage and administration
Chickens, turkeys and ducks
The product is administered in the drinking water. Prepare the solution with fresh tap water immediately before use. Once opened, use the contents of one sachet immediately. Any unused medicated water which should be discarded after 12 hours
In order to ensure consumption of the medicated water, animals should not have access to other water supplies whilst being treated.
The following formula may be used to calculate the amount of product required per day (in grams):
Number of birds x average live weight (kg)
25 (for 20 mg/kg) or 33 (for 15 mg/kg)
To ensure a correct dosage, bodyweight should be determined as accurately as possible to avoid underdosing. The uptake of medicated water depends on the clinical condition of the birds. In order to obtain the correct dosage the concentration of amoxicillin has to be adjusted taking into account water intake.
The recommended dosage is 15 mg amoxicillin trihydrate per kg bodyweight. The total period of treatment should be for 3 days or in severe cases for 5 days.
Recommended dosage is 20 mg amoxicillin trihydrate/kg bodyweight for 3 consecutive days.
Recommended dosage is 15-20 mg amoxicillin trihydrate/kg bodyweight for 3 days or in severe cases for 5 days.
For the medication of Pigs, Amoxinsol 50 may be administered in the drinking water or administered by addition to liquid feeds produced with commercial feed. It may not be used in dry feeds.
Administration via the drinking water
a. Administer in the drinking water to give 20mg/kg bodyweight daily. The dose should be divided and administered at approximately 12 hourly intervals for up to 5 days. Dissolve the contents of one sachet (150g of the product) in the requisite quantity of water immediately before use.
b. For administration via the drinking water, the solution should be prepared with fresh potable water.
i. Any medicated water which is not consumed within 12 hours should be discarded.
ii. In order to ensure consumption of the medicated water, animals should not have access to other water supplies whilst on treatment
Administration in liquid feed
a. Administer in the liquid feed, to give 20mg amoxicillin trihydrate/kg bodyweight daily for up to 5 days. Medicated feed should be freshly prepared on at least 3 occasions per day over the treatment period. The daily dose should be calculated based on the number of animals and average weight and then divided by the number of feed lots prepared in the day.
b. Medicated liquid feed should be prepared with fresh potable water.
c. Dissolve the required amount of Amoxinsol 50 in water at a rate of 25g/L before addition to the feed. This may be done by dissolving the contents of one sachet (150g of the product) in approximately 6L of water immediately before use.
d. After adding the product to some or all of the water needed to make the liquid feed, ensure the product is fully dissolved. Dissolution of the product can take up to 10 minutes. This medicated water can then be mixed with the dry complete meal and if appropriate, the remaining water. The system used should ensure that the medicated water is evenly distributed into the feed. Once prepared the final medicated liquid feed should be fed to the pigs immediately.
e. The medicated liquid feed should not be fermented and should not be stored.
f. Stability of amoxicillin in all commercial feeds has not been established. In order to ensure that any loss of amoxicillin activity is minimized, the quantity of medicated liquid feed prepared should not exceed the amount of feed which will be consumed within 4 hours.
i. Any medicated liquid feed which is not consumed within 4 hours should be discarded
ii. Although restricted access to other water supplies would help ensure medicated liquid feed is consumed, separate clean potable water should remain available at all times for welfare reasons.

Further information
Amoxicillin is a bacterial semisynthetic penicillin with a broad spectrum of activity against Gram positive and Gram negative bacteria.  It owes its activity to the inhibition of the development of the peptidogylcan network structure in the bacterial cell wall.
Amoxicillin is well absorbed following oral administration and it is stable in the presence of gastric acids. Excretion of amoxicillin is mainly in the unchanged form via the kidneys to give high concentration in renal tissue and urine. Amoxicillin is well distributed in body fluids.  
Studies in birds have indicated that amoxicillin is distributed and eliminated more rapidly than in mammals. Biotransformation appeared a more important route of elimination in birds than in mammals.
