ABSTRACT
The effect of intramammary injection of rbG-CSF (4×105 units/10 ml saline) on quarter milk
levels of CL activity and SCC and shedding patterns of total bacteria and S. aureus in an udder
suffering from S. aureus subclinical mastitis was investingated. The cytokine injection induced
significant increases in milk CL activity and SCC and significant decrease in milk S. aureus count.
