AbstractThe objectives of this study were (i) to characterise clinical health in dairy calves on an Irish research farm during the artificial calf-rearing period and (ii) to determine whether calves’ pre-weaning intakes and feeding behaviour, recorded by electronic calf feeders, changes in response to incidents of bovine respiratory disease (BRD). Holstein-Friesian (H-F) and Jersey (J) calves were fed by automatic milk replacer (MR) and concentrate feeders. Feeding behaviour, including MR consumption, drinking speed, number of rewarded and unrewarded visits to the feeder as well as concentrate consumption, was recorded by the feeders. A modified version of the Wisconsin calf health scoring criteria chart was used to score calves’ clinical measurements and identify incidences of BRD. Thus, 40% of calves were found to have at least one incident of BRD. Feeding behaviour was altered during incidents of BRD. The number of unrewarded visits to the feeder was reduced, by approximately four visits, for calves with BRD during the 3 d prior to the identification of BRD(P< 0.05) and tended to be reduced during the 7 d following the identification of BRD(P= 0.05), compared with healthy calves. Additionally, calves with BRD had a tendency for reduced net energy intake (approximately 8%) during the 3 d prior to the identification of BRD, compared with healthy calves. Therefore, calf feeding behavioural data, recorded by electronic feeders during the pre-weaning period, can indicate cases of BRD.

AbstractA pilot study was performed to evaluate the safety and serological responses after co-administration of two multivalent inactivated vaccines to pregnant cattle. One vaccine was directed against bovine respiratory disease (BRD) and contained antigens of bovine respiratory syncytial virus (BRSV), parainfluenza 3 virus (PI3) and Mannheimia haemolytica (Mh). The second vaccine targeted neonatal calf diarrhoea (NCD) and was composed of inactivated antigens of bovine rotavirus (BRV), bovine coronavirus (BCV) and E. coli. The use of these combinations have been used more and more by veterinary practitioners as there exist some clear evidence that both vaccines improves the passive protection via the colostrum for the relevant pathogens. However, up until now, no safety or efficacy data has been available concerning such co-administrations. The safety of both vaccines and the serological responses to the BRD vaccine has been evaluated when used at the same time, but without mixing and compared to the responses to the administration of each vaccine independently. There was no evidence of any negative effect on calving or calf health in any of the vaccinated animals. The antibody levels against BRSV and Mh in the sera of the calves from cows vaccinated with both vaccines were not significantly different from the levels in the sera of calves vaccinated with the BRD vaccine alone. The results from this pilot study demonstrated that the co-administration of the two multivalent inactivated vaccines had no detrimental effect on the safety or serological responses to the BRD vaccine compared to the independent use of the vaccines.

Abstract Neonatal calf survival and health is predominantly dependent on sufficient consumption of immunoglobulin G (IgG) and the resulting transfer of passive immunity (TPI). In this study we investigate the potential for continued IgG secretion and temporal kinetics of mammary IgG output in sequential milkings performed at 0, 4, 16, 28, 40 and 52 hours post-calving in Holstein dairy cows. For colostrum (0 hour), we also scrutinize the relationships between IgG concentration, volume, refractometer readings (˚Bx values, Brix ®) and concentration of sugars (lactose and glucose). Mammary transcripts postpartum (0 hour) indicated that active IgG secretion continues beyond the first milking (colostrum; n=4-5). IgG measurements at the different timepoints indicated that colostrum represents only 25.1% of the total IgG produced across the six sequential milking timepoints, with a substantial 48.9% being secreted into transition milk over the next three timepoints (4-, 6- and 28-hour) combined. The differences on the basis of IgG concentrations across 0-, 4- and 16-hour milking timepoints were not statistically significant (p=0.1522; n=9). For colostrum, volume remained highly variable, even with induced let-down prior to milking (n=27). Nonetheless, colostrum IgG secretion was significantly co-regulated with volume (R 2=0.915; p&lt;0.001; n=18), an association that was stronger than that measured for lactose (R 2=0.803; p&lt;0.001; n=18) and glucose (R 2=0.467; p=0.002; n=17). Comparing colostrum ˚Bx values to absolute IgG concentrations showed no correlation (R 2=0.127; p=0.07; n=27); biochemical separation of colostrum components indicated that both proteins and non-protein solutes could affect ˚Bx values (p&lt;0.0001 for both; n=5). This suggests that ˚Bx values do not reasonably indicate IgG concentration to serve as a measure of “colostrum quality.” Additionally, our finding that early transition milk (4-, 6- and 28-hour) can contribute substantially more IgG than colostrum forces a rethink of existing feeding paradigms and means to maximize TPI in calves. Collectively, our results reveal the remarkable value of early transition milk and caveats to colostrum assessments that could advance application in enhancing neonatal calf health.
