Abstract
A whole series of factors affect the degree of absorption of colostral immunolobulins. One of the most important factors is the time of feeding of newborn calves with colostrums in the first hours following birth. The objective of these investigations was to determine the effect of immunoglobulin concentration in colostrum on the process of immunoglobulin absorption during the first day of life of calves. A farm of Holstein-Friesian cows was selected for these investigations. The examinations covered 35 cows. For the examination of total immunoglobulin concentration, colostrum was taken two hours after calving. The immunoglobulin concentration was determined using the method of paper electrophoresis and RID-partigen immunodiffusion plates (INEP, Zemun). The amount of immunoglobulin in blood serum of calves was determined using the method of the zinc sulphate turbidity test (ZST). The average concentration of immunoglobulin in colostrum two hours after calving was 65.95?15.80 g/l. The biggest reached average concentration of immunoglobulin in blood serum of calves was determined following the absorption of immunoglobulin during the first day, and it amounted to 27.18?10.2 g/l, which presents 1.91? 0.72 g/kg of the body mass of calves. The straight-line linear equation is _ =0.595+0.25xi. The correlation coefficient between taken and resorbed immunoglobulins amounts to r=0.80. It can be concluded on the grounds of the obtained results that the amount of immunoglobulin in colostrum in the first drinking is of primary importance for the health status of the calves and that resorption is increased by 0.25 grams with every gram of immunoglobulin taken with colostrum.
Highlights
Na stepen apsorbcije kolostralnih imunoglobulina, uti~e ~itav niz faktora
Na osnovu dobijenih rezultata moe se zaklju~iti da je koli~ina imunoglobulina u kolostrumu pri prvom napajanju od primarnog zna~aja za zdravstveni status teladi i da se sa svakim gramom imunoglobulina unetih kolostrumom pove}ava resorpcija za 0,25 grama
Na osnovu podataka o koncentraciji gamaglobulina u kolostrumu, popijenoj koli~ini kolostruma, koncentraciji imunoglobulina u krvnom serumu, telesnoj masi teladi na ro|enju i koli~ini njihove plazme, izvr{ena je procena koli~ine kolostruma i imunoglobulina unetih i resorbovanih od strane novoro|ene teladi, {to je izraeno kao procenat (%) ili g/kg telesnu masu (TM) teladi
Summary
Na stepen apsorbcije kolostralnih imunoglobulina, uti~e ~itav niz faktora. Jedan od najvanijih faktora je vreme napajanja novoro|ene teladi kolostrumom u prvim ~asovima posle dolaska na svet. Koli~ina imunoglobulina u krvnom serumu teladi odre|ena je metodom zamu}enja zink sulfata (ZST). Na koli~inu apsorbovanih kolostralnih imunoglobulina, koja se meri na osnovu nivoa imunoglobulina u krvnom serumu teladi, uti~e ~itav niz faktora.
