Biochemical differences between crop tissue and crop milk of pigeons (Columba livia)
1997
Bharathi, L. | Shenoy, K.B. | Hegde, S.N.
Biochemical differences between crop tissue (CT) and crop milk (CM) of pigeons were evaluated in terms of activity of certain enzymes, content of protein and nucleic acids and mitogenisity in vitro. Whereas the activities of aspartate transaminase, alanine transaminase, maltase, trehalase and cellobiase were significantly higher in CT, those of alkaline phosphatase, leucine aminopeptidase, gamma glutamyl transpeptidase, acid phosphatase and lactase were greater in CM. The CM also showed significantly higher levels of protein, DNA and RNA than CT. In contrast, the in vitro mitogenic effect of CT was greater than that of CM, and this property was enhanced during the breeding period. The biochemical composition of crop milk did not differ significantly in the first 4 days of secretion. It appears that certain factors responsible for growth stimulation accumulate in the crop tissue of pigeons during incubation.
