“…On the other hand, variations that could characterize a peak of concentration were not observed in OC. In accordance with the present study, Lima (2008) observed the highest serum IgG concentration in newborn goat kids fed bovine colostrum at 48.75 ± 0.72 h of life. The author did not observe maximum value in the animals fed caprine colostrum.…”

“…In the present study, the highest serum IgG concentrations were observed in BC animals, with the maximum value at 24 h. Pauletti et al (2003), Machado Neto et al (2004 and Lima (2008) observed similar pattern in calves and goat kids that received colostrum with high antibody concentration. On the other hand, variations that could characterize a peak of concentration were not observed in OC.…”

“…In addition, the ovine colostrum can transmit pathogens like maedi-visna virus, so suckling is not recommended (Álvarez et al, 2005). In both conditions, a bank of bovine colostrum is an important management practice for small ruminants, ensuring the supply of adequate quantities of immunoglobulins to newborns and preventing the transmission of pathogens through maternal colostrum (Houwers et al, 1983;Lima, 2008).…”

The objective of this study was to investigate immunoglobulin G (IgG) and total serum protein (TP) acquisition in newborn Santa Ines lambs fed Holstein bovine or Santa Ines ovine colostrum as well as the cell proliferation rate in the animals' intestine epithelium. At 0 h and 6 h of life, 12 newborn lambs received 250 mL of bovine 1st milking colostrum (BC) and another 12 animals received 250 mL of ovine 1st milking colostrum (OC). Blood samples were collected at 0, 6, 24, and 72 h of life. Six animals were randomly slaughtered just after birth, without colostrum intake. The other animals were randomly slaughtered at 24 and 72 h. The IgG serum concentration at 6, 24 and 72 h were significantly higher for BC, 16.32 ± 6.19; 33.80 ± 5.68 and 27.95 ± 5.46 mg/mL respectively, compared with OC, 11.31 ± 6.08, 21.02 ± 6.53 and 19.88 ± 7.31 mg/mL. BC showed higher (P < 0.05) TP values (7.29 ± 0.87 and 6.89 ± 0.30 g/100 mL) at 24 and 72 h in relation to OC (5.73 ± 1.35 and 5.69 ± 0.57 g/100 mL). At birth, the animals showed 32.52%, 45.47% and 30.60% cells in division for the duodenum, jejunum and ileum, respectively. At 24 h, the OC animals showed lower (P < 0.0001) mitotic cell percentage in the duodenum (42.12%) and ileum (35.66%) in relation to the BC animals, 46.44% and 39.74%, respectively. At 72 h, a lower (P < 0.0001) rate of proliferation was observed in the duodenum crypts of the OC animals (36.28%) compared with BC (43.18%). The results indicate that this lacteal secretion can accelerate the epithelium renovation process and can be used as an alternative source of IgG for newborn lambs.

“…Nos bovinos, a concentração de IgG representa 35 a 47% da fração protéica, apresentando alta relação entre as duas variáveis (MACHADO NETO et al, 2004;PAULETTI et al, 2007). Nos ovinos e caprinos, em média 35% da proteína total sérica corresponde a imunoglobulinas (HALLIDAY, 1974;LIMA, 2008). A correlação da flutuação de IgG e proteína total neste período de vida do animal pode chegar a 0,81 em ovinos e 0,78 nos bovinos (HALLIDAY, 1974;PACKER, 1986;PAULETTI et al, 2002;KINDLEIN et al, 2007).…”

Dinámica de la transferencia de inmunoglobulina G en el binomio madre-cría de la especie caprina

La placenta de la cabra impide el pasaje de anticuerpos desde la circulación materna a la fetal. Por tanto, éstos son transferidos luego del nacimiento a través del calostro ingerido. Los objetivos del ensayo fueron establecer la cinética de la concentración de inmunoglobulina G (IgG) en cabritos durante sus primeros 5 meses de vida y relacionar la concentración de IgG en suero y calostro de cabra con la concentración en suero del cabrito, así como evidenciar si existen diferencias en la cinética de la concentración de IgG de cabritos respecto al tamaño de la camada. Se utilizaron 16 cabras Anglo Nubian y 26 crías divididas en dos grupos según el tamaño de la camada. Las concentraciones de IgG en calostro y suero se valoraron por inmunodifusión radial. Los resultados mostraron que las concentraciones de IgG en suero y calostro de cabras fueron de 1749 y 3720 mg/dl (p<0,001). En los cabritos los valores fueron no medibles a las 0 h y máximos a las 18 h (1814 mg/dl). A los 21 días, la concentración sérica de IgG en cabritos fue de 1677 mg/dl, valor significativamente diferente al de las cabras y al de los cabritos a las 18 h (p<0,001). Con respecto al tamaño de la camada no se encontraron diferencias en las concentraciones de IgG en suero y calostro de cabras (p = 0,77), al igual que en la cinética en suero de los cabritos (p = 0,48). Se concluye que los niveles de IgG en cabritos se mantienen en valores similares a los de sus madres desde las 6 h hasta los 150 días y que el tamaño de la camada no influye en la concentración de IgG de los cabritos.
