In some parts of the world M. gallisepticum has been eradicated from broiler breeder flocks, but still M. synoviae is relatively common. In some endemic areas, where there is a high population density of breeders and broiler producers, MG still is an important pathogen and needs preventing.
The Denagard breeder programme offers a proven economic protection in the face of chronic and acute MG infection challenges and, at a cost of only 1.25mg tiamulin/HH for the whole laying period.
- Increases egg production
- Increases hatchability
- Reduces hen mortality
- Produces more chicks (upto 26/HH) in chronically infected flocks.
Breeder layer programme
From point of lay this valuable programme for breeder layers has been developed:
Denagard is administered at 0.0125% (125ppm) in the water for 3 days each month.
The equivalent dosage in feed is 250ppm Denagard for 3 days / month (Link – Solubility / palatability), which is sometimes preferred, and gives approximately 12.5mg tiamulin/kg bodyweight.
|Breeder layer programme
Over the whole laying period (42 weeks) the hen receives a total of 1.25g of tiamulin, which is an approximate cost of 1-2 chicks. The return can be up to 26 chicks/HH depending on the severity of the infection. Denagard provides a very cost/effective approach to the control of mycoplasma infections in broiler breeders.
Comparative field trials
Three field trials were carried out using the Denagard Breeder programme in drinking water and comparing it to an untreated control, MG vaccinated (killed and live) controls
