Dynamics of the transfer of immunoglobulin G in the binomial mother-newborn of llama (Lama glama)
The transfer of immunity by colostrum in llama is a critical event in the survival of the newborn (teke).

Llama (Lama glama) crías calostro IgG sérica placenta epiteliocorial Llama (Lama glama) newborn colostrum IgG epitheliochorial placenta The transfer of immunity by colostrum in llama is a critical event in the survival of the newborn (teke). The objective of this work was to establish the kinetics of the concentration of immunoglobulin G (IgG) in tekes during the first 5 months of life and to relate the concentration of IgG in serum and colostrum of the llamas with the concentration in serum of the tekes. A cohort, observational and analytical study was designed. Twenty-five llamas and their respective offspring were studied. The concentration of IgG in colostrum and serum of the mothers was determined, and in tekes from birth to 150 days of life, using the simple radial immunodiffusion technique. The results showed an average concentration of IgG in llama serum of 4311.47 mg/dl and in colostrum of 23254.9 mg/dl. In the tekes at 0 h, the concentration of IgG was not measurable, reaching maximum values between 18 and 24 h, (4094.06 and 4197.95 mg/dl respectively), not finding in this period differences with the concentration of the maternal serum IgG (p 0.694). From 24 hours to 120 days a decrease in IgG levels was observed (p<0.0001), registering an increase at 150 days (p 0.0001). It is concluded that the values of colostral IgG are independent of the serum concentration in llamas and tekes, there being no association between them (p<0.0001). Colostrum provides levels of IgG that achieve a serum concentration in the tekes similar to those of their mothers at 24 hs postpartum. En las llamas la transferencia de la inmunidad pasiva a través del calostro es un evento crítico para la supervivencia de la cría (teke). El objetivo de este trabajo fue establecer la cinética de la concentración de inmunoglobulina G (IgG) en tekes durante los primeros 5 meses de vida y relacionar la concentración de IgG en suero y calostro de las llamas con la concentración en suero de los tekes. Se diseñó un estudio de cohorte, observacional y analítico. Se estudiaron 25 llamas y sus respectivas crías. Se determinó la concentración de IgG en calostro y suero de las madres y en tekes según una cinética establecida desde el nacimiento hasta los 150 días de vida, empleando la técnica de inmunodifusión radial simple. Los resultados mostraron una concentración media de IgG en suero de llamas de 4311,47 mg/dl y en calostro de 23254,9 mg/dl. En los tekes -a las 0 h posparto- la concentración de IgG fue no dosable, alcanzando valores máximos entre las 18 y 24 h (4094,06 y 4197,95 mg/dl respectivamente) no encontrando en este periodo diferencias con la concentración de la IgG sérica materna (p 0,694). Desde las 24 h hasta los 120 días se observó un descenso en los niveles de IgG (p<0,0001), registrándose un incremento a los 150 días (p 0,0001). Se concluye que los valores de IgG calostral son independientes de la concentración sérica tanto en llamas como en tekes, no existiendo asociación entre los mismos (p<0,0001). El calostro aporta niveles de IgG que en los tekes logran concentraciones séricas similares a las de sus madres a las 24 h posparto.

The transfer of immunity by colostrum in llama is a critical event in the survival of the newborn (teke). The objective of this work was to establish the kinetics of the concentration of immunoglobulin G (IgG) in tekes during the first 5 months of life and to relate the concentration of IgG in serum and colostrum of the llamas with the concentration in serum of the tekes. A cohort, observational and analytical study was designed. Twenty-five llamas and their respective offspring were studied. The concentration of IgG in colostrum and serum of the mothers was determined, and in tekes from birth to 150 days of life, using the simple radial immunodiffusion technique. The results showed an average concentration of IgG in llama serum of 4311.47 mg/dl and in colostrum of 23254.9 mg/dl. In the tekes at 0 h, the concentration of IgG was not measurable, reaching maximum values between 18 and 24 h, (4094.06 and 4197.95 mg/dl respectively), not finding in this period differences with the concentration of the maternal serum IgG (p 0.694). From 24 hours to 120 days a decrease in IgG levels was observed (p<0.0001), registering an increase at 150 days (p 0.0001). It is concluded that the values of colostral IgG are independent of the serum concentration in llamas and tekes, there being no association between them (p<0.0001). Colostrum provides levels of IgG that achieve a serum concentration in the tekes similar to those of their mothers at 24 hs postpartum. |
