During a two-day seminar held in Istanbul, Turkey, animal health company Huvepharma officially launched its new product Pharmasin 100% Water Soluble Granules (WSG).
The product is built around the macrolide antibiotic tylosin, to be used for pigs and poultry, for veterinary purposes. It had already been existing as a powder variety, to be used in premixes, but the company has now added a soluble variety to its portfolio, to cover all parts of the market.
Poultry & pigs
In poultry (broilers, pullets, turkeys), the product has received indications for use to prevent or cure respiratory infections caused by Mycoplasma gallisepticum and Mycoplasma synoviae; and also against necrotic enteritis caused by Clostridium perfringens.
In pigs, the product can be used to prevent or cure Porcine Intestinal Adenomatosis (PIA) associated with Lawsonia intracellularis and also enzootic pneumonia caused by Mycoplasma hyopneumoniae and Mycoplasma hyorhinitis.
Value of antibiotics
Several speakers in Istanbul focused on the value of antibiotics use – despite a tendency in some European countries to cut back on antibiotic use in Europe. Not surprisingly, one of the take home messages was that veterinarians need the widest variety tools of possible to help their livestock to stay healthy – and antibiotics should be among these.
On Wednesday, May 3, Prof Pascal Richez, spoke about pharmacokinetics, explaining the mode of action of tylosin – and explaining why soluble antibiotics may sometimes be more desirable – as antibiotics in water provide a constant intake even when animals are on a restricted feeding pattern.
He also presented ‘formulas’ so veterinarians can easily decide how much of the product to add to the water of certain target animals.
Gut health in chickens
Prof Filip Van Immerseel, University of Ghent, Belgium dived into the topic of gut health in chickens. In necrotic enteritis the key pathogen is the toxin producing bacteria Clostridium perfringens. Its effect is similar, as its presence may induce a lot of other secondary pathogens to also launch an attack on the animal’s gastro-intestinal tract.
Other speakers included Prof Steven McOrist (University of Nottingham, UK), Dr Anneke Feberwee (University of Utrecht, Netherlands), and Prof Erik Van Vooren (DM Institute, Belgium).
In the presentations it was emphasised that the soluble tylosin both is metabolised extensively and eliminated very quickly. In addition, it was stressed that managing the stall climate is also a very important tool to prevent the occurrence of pathogens.
As from January 1, 2006, the use of antibiotics as growth promoters has been forbidden in the European Union to avoid the risk of creating resistant bacteria.
