Vilofoss' Stalosan F evaluated on commercial dairy farm in Turkey
The effects of Vilofoss' Stalosan F on somatic cell count was investigated by Namık Kemal University in Tekirdağ, Turkey, the company said.
Results showed decreased mastitis problems and cows that stay at the feed alley for a longer time.
Commercial dairy farms in the Trakya region often face a high somatic cell count related to subclinical mastitis. To minimise the problem, it is important to research alternatives solutions under local Turkish conditions, Vilofoss noted. In this regard, keeping bedding area dry and reducing pathogen load appear to be an effective method.

During the trial, Stalosan F was applied to stalls, manure alley and the area of water supply on day 1, 2, 3, 10, 17, 24 and 31 at 50g/m2.
Trial results
For the determination of somatic cell count (SCC), milk samples were taken from the tank five times at seven-day intervals and analysed using De Laval SCC device.

Conclusion
At the end of the trial, SCC was decreased significantly in the treatment (Stalosan F) group. Most of the cows with subclinical mastitis was placed in the Stalosan F group (with, initially, high somatic cell count). It was observed that cows in the treatment group produced more milk than the control.
Milk pH is a parameter which indicates mastitis incidence. At the end of the four weeks, milk pH value at close to ideal limits was seen in the Stalosan group.
The results showed that Stalosan F decreased mastitis problems. Cows were also observed to stay at the feed alley for a longer time, Vilofoss said.
