“…Further, a moderate overdispersion is consistent with the intra-herd mortality clustering as detected via the widened confidence intervals in the gee-Poisson model. Mortality clustering has been described in calf and dairy cattle holdings (Moore et al, 2002;Bähler et al, 2012;Shahid, 2013). This corresponds to the view that mortality levels in holdings are multifactorial and often management-dependent (Welfare Quality, 2009;de Vries et al, 2011de Vries et al, , 2013.…”

“…Ranches raising dairy calves in the western US have become a large industry and it is not uncommon for bull calves arriving at these ranches to have inadequate passive transfer [24]. In spite of that, calves are successfully raised with survival in the first 4 weeks of life greater than 86% [24].…”

“…In spite of that, calves are successfully raised with survival in the first 4 weeks of life greater than 86% [24]. However, calves with failure of passive transfer experience greater morbidity and require additional treatments for health problems, which might impair performance and increase the use of antibiotics [3].…”

Effect of feeding live yeast products to calves with failure of passive transfer on performance and patterns of antibiotic resistance in fecalEscherichia coli

-Fifty-two newborn Holstein calves with serum IgG concentrations less than 0.73 g·dL -1 were randomly assigned to one of four treatments: no added live yeast (control), 0.5 g of live yeast added to the grain for 84 d (SC; Saccharomyces cerevisiae), 0.5 g of live yeast added to the milk for 42 d (SB; S. cerevisiae, spp. boulardii), and 0.5 g of live yeast added to the grain for 84 d and to the milk for 42 d (SCSB). Calves were offered 440 g of milk replacer DM for the first 42 d and grain for ad libitum intake throughout the study. Plasma was analyzed weekly for concentrations of glucose and β-hydroxybutyrate. Escherichia coli isolated from fecal samples collected every 2 weeks were used for determination of antibiotic resistance patterns. Calves receiving SC consumed more grain DM, had increased weight gain prior to weaning, and increased plasma glucose concentrations compared to controls. Days with diarrhea were reduced by feeding live yeast to calves. Antibiotic resistance in fecal E. coli was associated with the age of calves with highest levels of resistance observed in the 3 d calves. While calves receiving SCSB had higher levels of antibiotic resistance than controls, this effect was not associated with any of the other treatments. Improvements in performance of calves with failure of passive transfer were observed when live yeast was added only to the grain. Saccharomyces cerevisia / yeast / failure of passive transfer

“…The study was approved by the University of California, Davis (UC Davis) Institutional Animal Care and Use Protocol (Protocol Number 17630). Sample size calculation was based on a 50% mortality rate attributed to calves not ingesting sufficient colostrum (Tyler et al, 1999), alpha of 5%, power of 80% and a mortality rate of up to 13% during the first 4 weeks of life in calves failing to ingest sufficient colostrum at birth, in California (Moore et al, 2002). The total sample size required was 27 calves.…”

In calves, passive immunity of immunoglobulins can be acquired through ingestion of colostrum or colostrum replacers. Plasma can been used to supplement immunoglobulins in healthy or sick calves. Serum half-life of colostral derived immuglobulin G (IgG) is estimated to be 20 days. Half-life of IgG is important in determining response to antigens and timing of vaccination in calves. To date studies evaluating half-life of colostrum replacer or plasma derived IgG are lacking. The objectives of this study were to compare the serum half-life of IgG derived from colostrum, colostrum replacer and plasma in dairy calves reared up to 35 days of age. Thirty Jersey calves were randomly assigned to receive colostrum or colostrum replacer by oroesophageal tubing or plasma by intravenous administration. Serum samples were collected at 2, 5, 7, 10, 14, 21, 28 and 35 days. Serum IgG concentrations were determined by radial immunodiffusion. The results indicated that half-life for IgG in colostrum fed (28.5 days) or plasma transfused calves (27.3 days) was longer than colostrum replacer fed calves (19.1 days). Further studies are required to evaluate pathogen specific immunoglobulins in order to recommend vaccination timing in calves fed colostrum replacers.
