Mean serum IgG concentrations from parturition through 8 weeks of age in kittens that ingested colostrum (n=55–125, closed circles), colostrum-deprived kittens that ingested milk from surrogate queens in mid-lactation (n=18, open circles), and colostrum-deprived kittens fed a milk replacer (n=39, open triangles). Error bars indicate one SD of the mean. *Colostrum-fed kittens were significantly different from colostrum-deprived kittens. †Colostrum-deprived kittens fed milk replacer were significantly different from colostrum-deprived kittens fostered on surrogate queens and colostrum-fed kittens.
