Equiplas® Plus (Equine IgG) is USDA-licensed equine plasma with a high IgG level. Plasma contains a minimum IgG level of 2800 mg/dl and one bag will increase a normal foal’s IgG by about 400 mg/dl.
This product is available in 950-ml bags · Foals that are ill will not show the IgG increases indicated above because of rapid utilization of the transfused antibodies · The half-life of administered immunoglobulins is about 21 days in the normal foal and as low as 8 days in the sick foal · The amount of IgG required to confer protection on the young foal is very dependent on the environment and has been reviewed extensively · We recommend a minimum of 400 mg/dl in some situations and over 800 mg/dl in others
