“…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. Argüello et al (2004) described IgG concentrations of 5.19 mg/mL in kids with failure in immune passive transfer; neither group in the present experiment had IgG concentrations indicative of immune passive transfer failure.…”

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.

“…Maximum serum Ig concentrations were reached sooner after sucking for IgG than for IgM and earlier for IgM than for IgA. This difference could be due to different rates of transport across the epithelial cells or to different intravascular and extravascular distribution of the different Ig classes (97). The percentages absorption of IgG, IgM, and IgA have been 90, 59, and 48% (132).…”

Enteric and respiratory disorders are the main hazards to successful calf rearing. The many interrelated factors in the etiology of these disorders are reviewed, and an attempt has been to classify the factors into those of a microbiological, immunological, nutritional, genetic, physical, or psychological nature. No one would dispute that enteric and respiratory disorders are the two main hazards to calf health, but many would argue about the relative importance of specific pathogens and other predisposing factors in the etiology of these disorders.

“…Animais que dependem do colostro para aquisição da imunidade inicial nascem agamaglobulinêmicos ou com níveis insignificantes de anticorpos séricos. Após a ingestão do colostro essa concentração se eleva acentuadamente alcançando em ruminantes recém-nascidos níveis máximos na corrente sangüínea entre 12 e 48 horas de vida (McCOY et al, 1970;LOGAN et al, 1978;KRUSE, 1983;PACKER, 1986;PAULETTI et al, 2002).…”

“…Segue-se a esse período, um aumento gradativo da concentração, reflexo da atividade de produção endógena de imunoglobulinas que se estabelece. A flutuação de imunoglobulinas, especialmente de IgG, que se verifica na corrente sangüínea do recém-nascido, caracteriza a transição de imunidade passiva para ativa (TENNANT et al, 1969;BUSH et al, 1973;HUSBAND;LASCELLES, 1972;LOGAN et al, 1978;PACKER, 1986;PAULETTI et al, 2002).…”
