ornamental birds (all CMS except FR)

ORNICURE, powder for use in drinking water for racing pigeons and ornamental

birds (FR)


Per 1 gram

Active substance:

Doxycycline hyclate 150.0 mg, equivalent to 130.0 mg of doxycycline base


For the full list of excipients, see section 6.1.


Powder for use in drinking water.

A fine, light yellow to yellow powder.


4.1 Target species

Racing pigeons and ornamental birds, particularly Psittaciformes (e.g. African grey

parrots, Goffin's cockatoos, cockatiels)

4.2 Indications for use, specifying the target species

Treatment of infections caused by micro-organisms susceptible to doxycycline:

Racing pigeons:

Chlamydophila psittaci, Pasteurella multocida, Mycoplasma spp.

Ornamental birds:

Chlamydophila psittaci

4.3 Contraindications

Do not use in case of hypersensitivity to tetracyclines.

4.4 Special warnings for each target species

The uptake of medicated drinking water by animals can be altered as a consequence

of illness and should be monitored carefully. In case of insufficient uptake of water, it

is advised to administer doxycycline directly into the crop or to medicate parenterally.

AN 01487/2014

Doxycycline (re)absorption may be reduced when birds are given grit. It is therefore

recommended to suppress grit and mineral additives during the treatment in pigeons

and to limit calcium to a maximum content of 0.7% in pelleted feed in parrots.

4.5 Special precautions for use

Special precautions for use in animals

Due to variability (time, geographical) in the susceptibility of bacteria to doxycycline,

bacteriological sampling and susceptibility testing of micro-organisms originating from

diseased animals are strongly recommended.

Medication should be combined with good management practices, e.g. good hygiene

and ventilation and, as far as applicable, appropriate stocking density.

Use of the product deviating from the instructions given in the SPC/product literature

may increase the prevalence of bacteria resistant to doxycycline due to the potential

for cross resistance and may decrease the effectiveness of the treatment.

Use of the product should take into account official and local antimicrobial policies.

Avoid administration in oxidized drinking equipment.

See section 4.10 for additional warnings.

Toxic concentrations might also be reached in birds housed in hot, outdoor climates

where water consumption is increased. Birds undergoing treatment should be

monitored for signs of doxycycline toxicosis, including lethargy, inappetance,

inactivity, and passing yellow or green urine. Doxycycline toxicosis caused hepatic

damage and dysfunction that may result in high plasma AST, lactate dehydrogenase,

and bile acids. Doxycycline treatment should be discontinued and general supportive

care started if doxycycline toxicosis is suspected.

The quality of the drinking water may influence the bioavailability of the product. See

Section 4.9.

Special precautions to be taken by the person administering the veterinary medicinal

product to animals

People with a possible allergy to tetracyclines are advised not to handle this product.

Avoid direct skin contact with the drug and inhalation of dust particles during the

preparation and administration of the medicated drinking water to prevent

sensitisation and contact dermatitis.

It is recommended to wear impermeable gloves (e.g. rubber or latex) and an

appropriate dust mask (disposable half-mask respirator conforming to European

Standard EN 149 (FFP2) or a nondisposable respirator to European Standard EN

140 with a filter to EN 143) during the preparation and the administration of the

solution. In the event of eye or skin contact, rinse the affected area with large

amounts of clean water and if irritation occurs, seek medical attention. Wash hands

and contaminated skin immediately after handling the product. Do not smoke, eat or

drink while handling the product.

If you develop symptoms following exposure such as skin rash, you should seek

medical advice and show this warning to the physician. Swelling of the face, lips or

eyes, or difficulty with breathing are more serious symptoms and require urgent

medical attention.

In case of accidental ingestion, seek medical attention.

4.6 Adverse reactions (frequency and seriousness)

As for all tetracyclines, on rare occasions allergic reactions and photosensitivity may

occur. Intestinal flora may be affected if treatment is prolonged (> 10 days), and this

may result in digestive disturbance. If suspected adverse reactions occur, treatment

should be discontinued.

A slight weight loss may occur.

4.7 Use during pregnancy, lactation or lay

The safety of the veterinary medicinal product has not been established during the

reproduction period, i.e., the time period from mating until the end of feeding the

progeny. During this time period the use of the product is not recommended.

4.8 Interaction with other medicinal products and other forms of interaction

Concurrent administration of doxycycline with any divalent cations (e.g. Ca, FE, Mg,

Al, divalent ions of antacids) should be avoided as this may lead to decreased


Doxycycline may enhance the effect of anticoagulants.

Do not administer together with kaolin, iron preparations and antacids.

Do not use in conjunction with bactericidal antibiotics, such as penicillins,

cephalosporins and beta-lactam antibiotics due to antagonism of the mode of action.

4.9 Amounts to be administered and administration route

For oral use.

To be administered in drinking water.

Racing pigeons:

- Treatment of infections due to Chlamydophyla psittaci susceptible to doxycycline:

46 mg doxycycline hyclate/kg bodyweight for at least 30 days

- Treatment of infections due to other pathogens susceptible to doxycycline

(Pasteurella multocida, Mycoplasma spp): 20 mg doxycycline hyclate/kg

bodyweight for 5 days

The medicated drinking water can also be administered directly into the crop (once


Ornamental birds, particularly Psittaciformes (e.g. African grey parrots,

Goffin's cockatoos, cockatiels):

For the treatment of infections due to Chlamydophyla psittaci susceptible to

doxycycline, the drinking water should be medicated in:

Page 3 of 7

Issued July 2016

AN 01487/2014

African grey parrots:

at a dose of 800 mg doxycycline hyclate/L drinking water ad libitum for 42 days or

54 mg doxycycline hyclate/kg bodyweight;

Goffin’s cockatoos:

at a dose of 400 mg doxycycline hyclate/L drinking water ad libitum for 42 days or 24

mg doxycycline hyclate/kg bodyweight;


at a dose of 400 mg doxycycline hyclate/L drinking water ad libitum (or 40 mg

doxycycline hyclate/kg bodyweight via feeding tube into the crop) for 30 days.

Owing to physiological and pharmacokinetic differences between the wide range of

species for which this product is indicated, the dose rates above are for guidance

only. Depending upon the species of animal and the infection to be treated,

alternative doses may be appropriate using an evidence-based approach. However,

any change in dosing regimen should be based on a benefit:risk assessment by the

responsible veterinarian, as tolerance at higher doses has not been investigated.

The exact daily amount of the product can be calculated using the following formula

as guidance:

... mg product/kg

bodyweight/day*  mean bodyweight

(kg) of birds to be

treated = ... mg product per L drinking


Mean daily water uptake (L) per bird

* 10 mg doxycycline hyclate/kg bodyweight is equivalent to 67 mg product/kg


To ensure a correct dosage, the body weight should be determined as accurately as


The uptake of medicated drinking water depends on the clinical condition of the birds.

To obtain the correct dosage the concentration in the drinking water may have to be

adjusted accordingly.

The medicated drinking water is a clear, colourless to yellow solution.

The maximal solubility of the product in soft/hard water at 20°C is around 390 g/L and

in soft/hard water at 5°C around 190 g/L.

Warning: The solubility of the product depends on the pH-value; in hard alkaline

water the product can precipitate. Water with a hardness of > 19.2°d and a pH-value

of > 8.1 is not suitable for dissolving this product.

The use of suitably calibrated weighing equipment is recommended if parts of the

packs are used. The daily amount is to be added to the drinking water such that all

medication will be consumed in 24 hours. Medicated drinking water should be

replaced every 24 hours.

AN 01487/2014

No other source of drinking water should be available during the medication period.

Racing pigeons should be kept in the pigeon loft during treatment.

The water supply system should be cleaned appropriately after the end of the

medication period to avoid intake of sub-therapeutic amounts of the active substance.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

Gastrointestinal effects. Ornamental birds and racing pigeons can regurgitate after

administration of high dosages.

In Goffin's cockatoos at a dose of 30 mg doxycycline hyclate/kg bodyweight changes

in plasma biochemical analyses suggest mild hepatic damage which disappears

7 days after the end of the treatment.

4.11 Withdrawal period(s)

Not authorised for use in birds intended for human consumption. Not authorised for

use in birds producing eggs for human consumption.


Pharmacotherapeutic group: antibacterial for systemic use, tetracyclines.

ATCvet code: QJ01 AA 02.

5.1 Pharmacodynamic properties

Doxycycline is a semi-synthetic tetracycline derivative.

In vitro doxycycline is primarily a bacteriostatic drug. It exerts its action by inhibiting

the protein synthesis of the bacterial cell. Doxycycline specifically binds on the

receptors of the 30S ribosomal subunits, causing the access of aminoacetyl-tRNA to

the receptor location of the RNA-ribosomal complex to be disturbed.

Inhibition of bacterial protein synthesis results in disturbance of all functions

necessary for the life of bacteria. Especially cell-division and the formation of the cell

wall are impaired.

Doxycycline is a broad-spectrum antibiotic, active against a large number of Gram-

positive and Gram-negative, aerobe and anaerobe micro-organisms.

Based on bibliographic references: Chlamydophyla psittaci (2013) and Mycoplasma

spp ( 2008) demonstrated to be highly susceptible. Pasteurella multocida results

(2014) demonstrated a great variability from high to low susceptibility, depending on

the geographical region where isolates came from.

Four resistance mechanisms acquired by microorganisms against tetracyclines in

general have been reported: Decreased accumulation of tetracyclines (decreased

permeability of the bacterial cell wall and active efflux), protein protection of the

bacterial ribosome, enzymatic inactivation of the antibiotic and rRNA mutations

(preventing the tetracycline binding to ribosome). Tetracycline resistance is usually

acquired by means of plasmids or other mobile elements (e.g. conjugative

transposones). Cross resistance between tetracyclines has also been described. Due

to the greater liposolubility and greater facility to pass through cell membranes (in

comparison to tetracycline), doxycycline retains a certain degree of efficacy against

microorganisms with acquired resistance to tetracyclines.

5.2 Pharmacokinetic particulars

The following data are based on bibliographic source:

In general, doxycycline is quite rapidly absorbed from the gastrointestinal tract,

widely distributed in the organism, not metabolised to any significant extent and

excreted mostly via the faeces.

It was shown that doxycycline was well absorbed from the gastrointestinal tract of the

pigeons after an oral dosage of 60 mg/kg b.w. A maximum plasma concentration of

8.1 μg/mL was reached 6 hours after administration and a plasma half-life of 11.3 h

was estimated.

At a daily oral dosage of 30 mg doxycycline/kg b.w. divided into 2 equal doses over a

time period of 14 days, mean peak-values in the plasma of 2.4 μg/mL and mean

trough-values in the plasma of 1.8 μg/mL were measured”.

A distribution volume of 1.3-1.4 L/kg was identified in pigeons.

In the liver, a high accumulation (values 8-26 µg/g) was noted 2 h after the last

administration, and was slightly reduced after 7 h (single values 7 to 17 µg/g).

For the lung, concentrations significantly higher than in plasma were measured

(average plasma levels =1.8 µg/mL after 2 h and 1.4 µg/mL after 6h), although the

maximal concentration and the variability is substantially less than in the liver (3-7

µg/g after 2 h and 2 to 4 µg/g after 7 h).
