“…The feeding of the calves was carried out within 2 h after the birth at an amount of 3 l. Around day 3-5 of their age, blood was taken from the jugular vein for the control of total proteins. This method was the same as the method of Jagoš and Bouda (1980) who recommended determining immunoglobulins between days 2 to 7 of the calf's age. The blood was centrifuged and, the value of serum proteins in particular calves was determined using a refractometer (PEN-PRO, Atago, USA) and recorded.…”

Passive transport of colostral immunoglobulins is essential for calves to maintain optimal health. There are many factors that influence the absorption of immunoglobulins such as colostrum density, timing of ingestion, volume of colostrum but also the method of feeding. This study compares two manners of feeding calves – the esophageal tube feeder (n = 97) and the nipple bottle (n = 97), and their effect on the number of all absorbed immunoglobulins (IgG, IgM, IgA, IgD, and IgE). It was statistically proven that absorption of immunoglobulins is better with the nipple bottle (P < 0.0001). The feeding of calves through a nipple bottle is more beneficial because the content of total protein is the higher than by the feeding through an esophageal tube feeder.

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.
