Comparison of freezing and lyophilizing for preservation of colostrum as a source of immunoglobulins for calves

Lyophilizing was compared to freezing as a method of colostrum storage. Eight lots of colostrum from the first milking were divided into two equal parts; one was frozen, and the other was lyophilized. Twenty-two newborn calves were divided into two groups and fed either 2 L of frozen and thawed colostrum or 2 L of reconstituted lyophilized colostrum. The calves were bled at 12, 18, 24, and 72 h after feeding, and levels of the immunoglobulins IgG1, IgG2, IgM, and IgA were determined with a radial immunodiffusion assay, in colostrum and sera. The mean concentration of individual immunoglobulin isotypes in the sera of calves fed either frozen or lyophilized colostrum did not differ significantly. Calves fed from the same lots of colostrum had similar immunoglobulin concentrations in their sera, irrespective of the method of storage. All immunoglobulin isotypes were absorbed with equal efficiency from frozen and lyophilized colostrum as determined by calculation of the absorption coefficient.
