The purpose of this study was to determine the effect of 8 wk of bovine colostrum supplementation on body composition and exercise performance in active men and women. Subjects were randomly assigned to a placebo (whey protein) and colostrum group (20 g/d in powder form). Each subject participated in aerobic and heavy-resistance training at least three times per wk. Body composition was assessed via dual x-ray absorptiometry analysis. Treadmill time to exhaustion, one repetition maximum strength (bench press), and the total number of repetitions performed during one set to exhaustion at a submaximal load for the bench press (50% and 100% of body weight for women and men, respectively) were ascertained. The whey protein group experienced a significant increase (P < 0.05) in body weight (mean increase of 2.11 kg), whereas the colostrum group experienced a significant (P < 0.05) increase in bone-free lean body mass (mean increase of 1.49 kg). There were no changes in any of the other parameters measured. Thus, supplementation with bovine colostrum (20 g/d) in combination with exercise training for 8 wk may increase bone-free lean body mass in active men and women.
would also depend on where you got the colostrum and or how its processed.
there is also potential postive effects on URTIs because of the immunoglobulins within the colostrum

BACKGROUND: Anecdotal reports suggest that bovine colostrum may prevent upper respiratory tract infection (URTI). There is scant evidence to support such claims, although salivary IgA protects against URTI, and it was recently shown that bovine colostrum increases salivary IgA. AIM OF THE STUDY: The present invesigation examined whether concentrated bovine colostrum protein (CBC) affected the incidence or duration of self-reported symptoms of URTI in adult males. METHODS: We examined logbooks containing self-reported symptoms of illness from previous studies which examined physiological effects of CBC. In these double-blind, placebo controlled studies, subjects had been randomly allocated to consume 60g. day(-1) of CBC (n = 93) or whey protein (WP) (n = 81) for eight weeks. Symptoms were coded using established criteria to identify those related to URTI. Since the incubation period for an URTI is up to five days, symptoms reported during the first week of supplementation (PRE-EXP) were analysed separately to preclude those arising from infection prior to study commencement. RESULTS: During PRE-EXP, there was no difference in the proportion of subjects taking the different supplements who reported symptoms of URTI (CBC, 11%,WP, 5%; 95% Confidence Interval (95% CI) -14% to 2%; P = 0.16). During the subsequent seven weeks (i. e. the experimental period), a significantly lesser proportion of subjects taking CBC reported symptoms of URTI compared with those taking WP (CBC, 32%,WP, 48%, P = 0.03; 95 % CI -30 % to -2 %), but symptom duration did not differ (CBC, 6.8 +/- 4.2 days,WP, 6.0 +/- 4.4 days; P = 0.27). CONCLUSION: This study provides preliminary evidence that CBC may enhance resistance to the development of symptoms of URTI.
but that would also depend on the processing etc.
