title: [Serum gammaglobulin titer in goat kids after colostrum administration: effect of commercial colostrum replacers].
abstract: Seven commercially available colostrum replacers were tested for their ability to substitute for goat colostrum as a source of gammaglobulin for goat kids. One hundred kids were fed with goat colostrum or colostrum replacer after separation from their mothers at birth. Blood samples were taken from ten kids at birth, and from all kids at 48 hours after birth. Samples were used to measure the total protein content and gammaglobulin concentration of serum. Kids fed with goat colostrum had higher gammaglobulin concentrations than newborn kids or kids fed with replacer. For three replacers, the gammaglobulin concentrations were the same as those of newborn kids. For three other replacers, the gammablobulin concentrations were similar but higher than those of newborn kids. For one replacer, the levels of gammaglobulin were higher than those of in newborn kids and higher than those measured after feeding of the other replacers. None of the replacers was an adequate substitute for goat colostrum as a source of gammaglobulins.
