Oxy Tetra-A Indications

Oxy Tetra-A is an animal and poultry formula which may be used to:

1. Give newborn animals and birds a healthy start.

2. Prevent setbacks from stress.

3. Prevent or treat specific diseases.

4. Improve weight gain.

Administration: Oxy Tetra-A may be given in 3 ways:

1. As a Drench - for individual treatment

2. In Water - for entire herd or flock.

3. In Feed - sprinkled on or mixed.

Contents: Each 400 grams of Oxy Tetra-A contains 22 grams Oxytetracycline Hydrochloride in a soluble base. This is the same as 55 mg/g or approximately 250 mg per teaspoon.


Milk taken from treated animals within 60 hours after the latest treatment must not be used in food. Eggs taken from treated birds within 60 hours after the latest treatment must not be used in food. Treated animals must not be slaughtered for use in food for at least 7 days for poultry and 10 days for swine and cattle, after the latest treatment with this drug. Do not medicate bees with this drug for at least 4 weeks prior to the main honey flow. Honey or syrup stored during medication periods in combs for surplus honey, should be removed following final medication of the bee colony and must not be used for human food.

Directions for use: Swine: Scours - For treatment use 4 grams per 45 kg body weight in 2 1/4 kg of feed or 4.5 L of water. Treat for 4 to 5 days. In case of newborn pigs mix 4 to 6 grams per 30 mL water and give 2 grams of this mixture twice daily for 3 days. Prevention levels should be half those for treatment.

Respiratory Diseases - For treatment use 8 grams per 45 kg of body weight or 4.5 L of water and give for 4 to 5 days.

Atrophic Rhinitis - As an aid in maintaining weight gain in the presence of this disease, mix 4 to 8 grams per 4.5 L of water and give continuously (Oxy Tetra-A will not act on the organism causing this disease).

Leptospirosis - Mix 12 grams per 4.5 L of water and give continuously, as an aid reducing urinary shedding of leptospiral organisms, reducing incidence of abortion, increasing survival, and weaning of healthier pigs.

1 teaspoon per 4.5 L = 400 grams per 4000 litres

2 teaspoons per 4.5 L = 400 grams per 2000 litres

Equivalents: 4 g of powder = 1 level teaspoonful, 1 Imperial gallon = 4.5 L, 280 L = 62 Imperial gallons.

Cattle and calves: Scours: For treatment use 4 grams per 45 kg in 60 to 90 mL of water or milk as a drench. For herds use 2 grams per 4.5 L of water, treat for 4 to 5 days. For prevention use half the treatment level.

Respiratory Diseases - For treatment or prevention use 4 to 8 grams per 45 kg of body weight in drinking water or in 60 to 90 mL water or milk as a drench. For herds use 2 to 4 grams per 4.5 L of drinking water.

Bees: Dusting - Mix 4 g with 35 g or 400 g (1 pouch) with 3.5 kg of powdered sugar. Apply the mixture on the outer parts or ends of the frames at the rate of 35 g per colony.

Syrup - Mix 4 g, dissolved in a small quantity of cold water, with 3 kg of a one part sugar, one part syrup mixture (or 400 g/300 kg). Bulk feed the syrup at the rate of 2.5 kg per colony using feeder pails or division board feeders, or by filling the combs.

General - For both methods, usually 3 applications at 4 or 5 day intervals a re required in the Spring and/or Fall. Honey from bee colonies like to be infected with foulbrood should not be used for preparation of medicated syrup supplements since it may be contaminated with spores of foulbrood and may result in spreading the disease.

Chickens and turkeys: Chronic Respiratory Disease - Use 4 grams per 4.5 L of drinking water or 2 1/4 kg of feed and administer from onset until a few days after the symptoms disappear.

Blue Comb - For treatment 4 grams per 4.5 L drinking water or 2 1/4 kg feed for 5 days or until a few days after symptoms disappear. For prevention use half the treatment level.

Synovitis - Mix 4 grams per 4.5 L of drinking water or 2 1/4 kg of feed.

Stress Conditions - When moving birds, vaccinating or when birds are exposed to extreme temperature changes, give 2 grams per 4.5 L of drinking water. This is recommended as an aid in preventing diseases caused by susceptible organisms.

Note: Bees: Medicated syrup should be used immediate and should be consumed within one week. Chickens, Turkeys, Swine, Sheep and Cattle: Fresh solutions should be prepared daily. It is also important to ensure adequate fluid intake, as amounts are based on average daily intakes. This also applies to feeds, where adequate intake is needed to ensure proper dosing. If symptoms persist after using this product as outlined, consult your veterinarian.
