Abstract

The protein content and amino acid composition of the uterine milk of swine and cattle were analyzed using slaughterhouse-derived samples. For both species, the majority of the dry matter of uterine milk consisted of materials of protein nature (swine: 68.1%, cattle: 73.3%). Free amino acids constituted approximately 0.3% (swine) and 0.5% (cattle) of the dry matter. In the uterine milk of sows, the high ratio of serine, glycine and acidic amino acids (overall ratio: 65%) was remarkable. No such striking values were found for the bovine species; however, the uterine milk of cows was also characterized by the predominance of acidic amino acids. Total amino acid content of the uterine milk was compared with that of freshly milked colostrum. With the exception of glutamic acid in sows and methionine and glutamic acid in cows the uterine milk and the colostrum had identical amino acid content. It is concluded that the embryotroph can be considered a transition between the blood and the colostrum.
