“…Changes seen in colostrum during the first days of lactation were typical (Blum and Hammon, 2000). A decrease of γ‐GT and AP activities in colostrum after the onset of lactation has been shown repeatedly (Majumder and Ganguli, 1972; Linden and Maraval, 1979; Grün et al., 1992). There are only a few studies on AST activity in colostrum and their findings vary greatly (Slesinger, 1969; Bostedt, 1983; Kurz and Willett, 1991).…”

Enzyme activities of gamma-glutamyltransferase (gamma-GT), alkaline phosphatase (AP) and aspartate-aminotransferase (AST) were measured from birth to the age of 28 days in calves which were fed colostrum at 0-2, 6-7, 12-13, or 24-25 h after birth. Enzyme activities were also measured in colostrum (first to fifth milking) and in mature milk. Activities were highest in the first colostrum milking and decreased to the lowest activities in mature milk. Plasma gamma-GT activity transiently increased after first colostrum intake and was greater in calves fed first colostrum within less than 6-7 h than in those fed first colostrum later than 12 h after birth. Activity of gamma-GT reflected the absorption of colostral gamma-GT, which decreased with time after birth. The AP activity transiently increased after colostrum intake and was higher in calves fed colostrum within the first 12 h of life than in those fed later after birth. The transient rise of plasma AP activity also indicated absorption of colostral AP, although endogenous sources of AP could not be excluded. The activity of AST also transiently increased after colostrum intake but there was no association with time of first colostrum feeding, indicating that the rise of plasma AST activity was the consequence of enhanced endogenous production and was independent of colostrum intake. In conclusion, there are different causes leading to postnatal changes in enzyme activities.

Klimes J., P. Jagos, J. Bouda, S. Gajdusek: Basic Qualitative Parameters of Cow Colostrum and their Dependence on Season and Post ParIum Time. Acta vet. Hrno, 55,1986: 23-39.Under conditions of large scale' dairy unit for 2144 cows 19 physicochemical and biochemical parameters of cow colostrum and the influence of season and time after parturition on these parameters have been studied. Average samples of colostrum from the first milking, on the 3rd and 5th day post parturition were collected from cows -cross-breds of Bohemian Pied x Black Pied Lowland breeds. In summer (June) and winter (February) season colostrum of 13 and 24 cows, resp. was examined.In most parameters the highest values were found in colostrum from the first milking, the most pronounced decrease being observed for the first three days after parturition. Only the pH and lactose values were found to be lowest in colostrum from the first milking. The fat content, rennet coagulation time of colostrum and potassium concentration varied without a marked dependence upon the time elapsed after parturition. In summer season, significantly higher values of vitamin A, buffer capacity and dry matter were ob'served in at least two out of three investigated milkings; in winter, significantly higher phosphorus levels were found.• Approximately 1000 times higher GMT activity when compared with that in cow blood plasma was demonstrated in colostral whey.Higher titratable acidity, higher levels of protein, gamma globulins, sodium, GMT activity and lower lactose concentration were determined in colostrum samples from the first milking with a concentration of total protein in whey over 120 gil, when compared with colostrum with a decreased total protein content in whey.The determination of total protein concentration in colostral whey from the first milking could be regarded as a decisive criterion of the evaluation of colostrum quality. On the basis of colostrum quality the level of nutrition, maintenance, and health condition of mother in the last gravidity trimester may be assessed together with other factors which will influence further development of the calves.

“…Dans le lait de femme le phénomène est inverse, avec une très forte concentration dans le colostrum qui chute ensuite rapidement jusqu'à des taux très faibles dans le lait [ 118]. L'activité de la phosphatase alcaline chute de 267 à 41 llmol·min-I·kg-I entre la première et la huitième traite [80]. La N-acetyl-b-glucosarninidase est présente dans le colostrum à des taux 20 fois plus élevés que dans le lait [49,56] et son activité chute rapidement dans les jours qui suivent le part (figure 3).…”
