FIG 1.

Innate immune components in bovine colostrum products (BCP). Growth hormone (GH) (A), insulin growth factor 1 (IGF-1) (B), tumor necrosis factor alpha (TNF-α) (C), and lactoferrin (D) were measured by ELISA in BCP resuspended in PBS-Tween (at a final concentration of 16 mg/ml) as described in Materials and Methods. Samples tested included ProMilk powders and tablets, IMM-124E 1-9 individual powders, IMM-124E powder and tablets, and Travelan (Table 2). Data represent the mean of duplicates when a single lot was tested (ProMilk or blended IMM-124E powder) or mean plus standard deviation (SD) (error bar) when multiple lots were available (IMM-124E HBC 1-9 [representing nine different lots of HBC powder] and two batches each of ProMilk, IMM-124E, and Travelan tablets), as listed in Table 2. Values that are statistically significantly different (P < 0.05) between HBC and ProMilk tablets by two-sample two-sided t test are indicated by an asterisk.
