AUAD, J. et al. Concentración de inmunoglobulina G en suero y calostro de cabras de acuerdo al número de crías de la camada. Rev. vet. [online]. 2016, vol.27, n.1, pp.11-13. ISSN 1669-6840.

The goat´s placenta is syndesmochorial, which does not allow the passage of immunoglobulins, and the goat kids are dependent of colostrum antibodies. Therefore, the colostrum is a vital event and no data is available on the impact of the concentration of immunoglobulin G (IgG) serum and colostrum regarding efficiency in multiple calving. The objectives were to establish the serum concentration of IgG levels in goats and its relationship to the concentration of IgG in colostrum, and to determine if the litter size influences in the maternal concentration of IgG. Sixteen Anglo Nubian goats were included in the study. Goats were divided into two groups according to litter size. Group 1: goats that gave birth to a single kid, and group 2 goats that gave birth two kids. IgG were measured by single radial immunodiffusion. Significant difference between the serum concentration and the colostrum IgG concentration was found (p 0,0001). Litter size did not influence sera and colostrum IgG concentrations (p 0,68).
