Published a new water medication simulator

April 24, 2012 - PRLog -- This tool calculates the quantity of drug to incorporate in the water when using a flow dispenser in swine production. In order to correctly medicate the water we need to know:

The dose of product per kg of live weight (coming up with the quantity per day).
The daily water consumption of the animals to be medicated.
Final concentration of the product in the drinking water.
Dispensing percentage of the stock solution (percentages lower than 2-4% can produce errors).
Quantity of stock solution needed.
Amount of product to add to the stock solution tank.
To calculate the stock solution, the farmer should enter the number of animals, their weight and the amount of water consumed by the pigs, the dosage, the product concentration and the regulation of the dispenser.

If the quantity of water consumed in the pig farm is not known, the simulator will provide an approximation based on number of animals, weight, temperature and quantity of water wasted. In any case, with the quantity of the stock solution consumed on the first day of medication, real water consumption can be calculated.

As seen in “Water medication in pigs”, before medicating the water we should know whether the product we are using is soluble. In practice slightly acidifying or neutralizing drinking water can be interesting when trying to improve the solubility of the products used. For example, in order to avoid problems with weak base molecules such as tetracycline, acidifying the drinking water would be a recommended measure in pig farming.

In the case of substances such as amoxicillin, ampicillin or phenoximeltilpenicillin, avoiding their use in acidified water (common these days in early phases like post-weaning) is recommended. Actually, strongly acidified waters with a pH < 5 could even limit the efficacy of these substances, affecting any possible results obtained from them.
