Influence of Formaldehyde and Propionic Acid on Composition and Microflora of Colostrum^{1 ,2,}

Department of Dairy Science, University of Illinois, Urbana 61801

ABSTRACT

Under laboratory conditions the effect of three percents of formaldehyde (.01, .05, and .1%) and three of propionic acid (.5, 1, and 1.5%) at two temperatures (21 and 37 C) on fermentation and preservation of colostrum was examined. Colostrum from second through fourth milkings postpartum was subdivided into 2.5-liter aliquots prior to addition of chemicals. Propionic acid maintained a low pH throughout the 28 days of fermentation. Formaldehyde held pH at its highest throughout fermentation. In control samples pH dropped initially and tended to increase between 7 and 14 days at both temperatures. Similar changes occurred for additions of formaldehyde at 37 C. Formaldehyde and propionic acid reduced protein degradation at 21 and 37 C compared to naturally fermented colostrum. Microbial growth, particularly coliforms, was retarded by additions of both propionic acid and formaldehyde.
