“…Thus, IgG absorption was related to apoptotic changes in enterocytes. Serum blood IgG was not recorded in the present experiment, but previous experiments (Castro et al, 2005(Castro et al, , 2007 demonstrated that the main period for IgG absorption in kid goats was the first 24 h of life. On d 2 of life, the cytoplasm and vascular villi of some enterocytes displayed marked IgG immunostaining (Figure 1; arrow in IgG on d 2).…”

Ten newborn kids were used to evaluate the relationship between apoptosis and passive immune transfer in neonatal enterocytes. Kids were slaughtered in groups of 2 at birth, 1, 2, 3, or 60 d postpartum, and samples of duodenal epithelium collected from each animal. Samples were fixed, dehydrated, and embedded in paraffin wax. Sections were assessed for apoptotic cells and immunostained for IgG. Our results suggest that IgG absorption is mediated by apoptotic enterocytes. Thus, delaying apoptosis may improve the success of passive immune transfer.

The effect of colostrum intake on blood plasma proteome profile in newborn lambs: low abundance proteins

et al. 2014

BackgroundColostrum intake by newborn lambs plays a fundamental role in the perinatal period, ensuring lamb survival. In this study, blood plasma samples from two groups of newborn lambs (Colostrum group and Delayed Colostrum group) at 2 and 14 h after birth were treated to reduce the content of high abundance proteins and analyzed using Two-Dimensional Differential in Gel Electrophoresis and MALDI MS/MS for protein identification in order to investigate low abundance proteins with immune function in newborn lambs.ResultsThe results showed that four proteins were increased in the blood plasma of lambs due to colostrum intake. These proteins have not been previously described as increased in blood plasma of newborn ruminants by colostrum intake. Moreover, these proteins have been described as having an immune function in other species, some of which were previously identified in colostrum and milk.ConclusionsIn conclusion, colostrum intake modified the low abundance proteome profile of blood plasma from newborn lambs, increasing the concentration of apolipoprotein A-IV, plasminogen, serum amyloid A and fibrinogen, demonstrating that colostrum is essential, not only for the provision of immunoglobulins, but also because of increases in several low abundance proteins with immune function.

“…After the initial increase in IgG serum concentrations between birth and d 1, there was a slight decrease in both experimental groups. Argüello et al (2004), Castro et al (2007), and Rodríguez et al (2009) reported similar blood serum peak times for IgG concentrations in Majorera kids. This temporal change in IgG concentration is in accordance with observations made by Logan et al (1978) in calves, where the maximum IgG level was reached between 16 and 48 h postpartum.…”

To investigate the use of sodium dodecyl sulfate (SDS) as a biocide on goat colostrum, 2 experiments were performed. In the first, 20 goat colostrum samples were divided into 3 aliquots. A different treatment was performed on each aliquot: pasteurization (56°C, 30 min) or addition of SDS to a final concentration of either 0.1 or 1% (36°C, 10 min). Immunoglobulin G and colony-forming units were evaluated before and after treatment. Both pasteurization and treatment with 1% SDS significantly reduced the colony-forming units in colostrum. Treatment with 0.1% SDS was not effective at reducing the colony-forming units in colostrum. The IgG concentration of pasteurized colostrum was significantly lower than that of untreated colostrum, whereas treatment with 1% SDS did not affect the colostrum IgG concentration. In the second experiment, the effects of SDS colostrum treatment on immune passive transfer were evaluated. Forty goat kids were fed either refrigerated colostrum or colostrum treated with 1% SDS twice daily for 2 d. Blood samples were obtained at birth and every day for 5 d. IgG, IgM, and IgA were measured in blood serum to monitor the passive immune transfer process. Creatinine, glucose, total cholesterol, blood urea nitrogen, bilirubin, and aspartate transaminase were also monitored to evaluate the health of kids. No differences in serum IgG, IgM, IgA, creatinine, glucose, total cholesterol, blood urea nitrogen, bilirubin, or aspartate transaminase levels were observed between groups. Our findings indicate that SDS is an efficient colostrum biocide that, unlike pasteurization, does not affect immune passive transfer or goat kid health.
