milk yield breed immunoglobulins immunoglobulin a calves colostrum serum suckler cow

Cow serum and colostrum immunoglobulin (IgG1) concentration of five suckler cow breed types and subsequent immune status of their calves (2004)

Abstract The objective of this study was to determine the effect of cow breed type on (a) cowserum and colostrum immunoglobulin (IgG1) concentrations and (b) subsequent calfserum IgG1 concentration and zinc sulphate turbidity (ZST) units. Five cow breedtypes were examined: LF (Limousin × Friesian), LLF (Limousin × (Limousin ×Friesian)), L (Limousin), C (Charolais) and SLF (Simmental × (Limousin ×Friesian)). Three blood samples were taken by jugular venipuncture from the cows atapproximately 90, 60 and 30 days pre partum, at parturition and at 15 days or more postpartum and from the calves at 48 (40 to 56) h post partum. Prior to suckling a 20 mlsample of colostrum was obtained. Milk yield was estimated using the weigh-suckleweightechnique. The decrease in serum IgG1 concentration in cows between 90 dayspre partum and parturition was greater (P < 0.01) for LF cows than all other breedtypes, except SLF. There was no difference between LLF, L, C and SLF cows. There wasno effect of cow breed type on colostrum IgG1 concentration. Milk yield was higher (P< 0.001) for LF cows than all other breed types, while that of SLF was higher than thethree remaining breed types, which were similar. Calf serum IgG1 concentration andZST units were higher (P < 0.01) for the progeny of LF cows than all others exceptSLF. There was no difference between the progeny of LLF, L, C and SLF cows. Calfserum IgG1 was affected by cow breed type and showed a positive relationship with cowserum IgG1 decreases in late pregnancy.
