For use in drinking water. The recommended dosage rates are:
Pigs
3.33 mg lincomycin and 6.67 mg spectinomycin/kg bw/day, for 7 days. This amounts to 15 mg powder/kg bw/day for 7 days.
Chickens
16.65 mg lincomycin and 33.35 mg spectinomycin/kg bw/day, for 7 days. This amounts to 75 mg powder/kg bw/day for 7 days.
Treatment should be initiated as soon as first clinical signs occur.
For the preparation of drinking water, the incorporation rate of the veterinary medicinal product in water will depend on the bodyweight of the animals and their actual daily intake of water.
To ensure a correct dosage and avoid underdosing, mean bodyweights in the group of animals and daily water consumption should be determined as accurately as possible.
The medicated drinking water should be the sole source of drinking water for the treatment duration. Any medicated water which is not consumed within 24 hours should be discarded.
In case of disease accompanied with significant decrease in water intake, parenteral treatment may have to be initiated.
Use the following indications as a basis for the precise calculation of incorporation rate of the veterinary medicinal product in drinking water.
Pigs
To determine the volume of dilution (in litres of drinking water) required for 150 g of the veterinary medicinal product, use the following formula:
Volume (L) for 150 g of the veterinary medicinal product | = | 10,000 x [daily water consumption per animal (L)] average bodyweight of one pig (kg) |
In pigs 150 g of the veterinary medicinal product corresponds to the dose for 10,000 kg of bodyweight per day. As an indication, standard water intake varies around 0.15 L/kg bw/day. The table below shows the volume of water to be used for dilution of 150 g of the veterinary medicinal product.
Water consumption | 150 g of powder = 100 g antibiotic activity which should be diluted in: |
0.1 L/kg bw/day | 1,000 L of drinking water |
0.15 L/kg bw/day | 1,500 L of drinking water |
0.2 L/kg bw/day | 2,000 L of drinking water |
0.25 L/kg bw/day | 2,500 L of drinking water |
Chickens
To determine the volume of dilution (in litres of drinking water) for 150 g of the veterinary medicinal product, use the following formula:
Volume (L) for 150 g of the veterinary medicinal product | = | 2,000 x [daily water consumption per bird (L)] average bodyweight of one bird (kg) |
150 g of the veterinary medicinal product corresponds to the dose for 2,000 kg of bodyweight per day.
