Technology of obtaining cow colostrum aseptic concentrates and their application to postpartum calves
The aim of the study was an analysis of the possibility of bacterial flora reduction in cow colostrum using the thermal method, ultraviolet waves, focused electromagnetic field, pulse electric field and filtration on ceramic membranes, as well as an assessment of immunoglobulin availability from dried and lyophilized colostrum protein concentrate obtained as a result of filtration. It was noted that total reduction of E. coli and coliforms from cow colostrum may be attained as a result of filtration on ceramic membranes. Other methods appeared to have little effect and not to be useful in this range. Calves in the first days of life, instead of colostrum, were fed with dried or lyophilized colostrum protein concentrate obtained as a result of membrane filtration. It was found that an application of dried and lyophilized cow colostrum concentrate instead of maternal colostrum caused significantly higher absorption of class G immunoglobulins in calves with regard to maternal colostrum. This was established as a result of the study conducted that dried or lyophilized cow colostrum concentrates, obtained as a result of filtration, can be used in supplementation and support of calves’ immunity, while their aseptic and concentrated form (dried material) allow better storage and distribution, as well as application in various herds.
