The value of serum IgG at 96 h of life was 9.8 and 7.6 mg/mL to LBC and GC, respectively. These values are similar to those found by Castro et al. (2005), 5.4 and 7.6 mg/mL, respectively, in goat kids fed four meals of frozen or lyophilized goat colos- trum containing 16 and 22.9 mg/mL of IgG, respectively. Lima et al. (2009), in turn, offering four meals of high quality goat colostrum (89.3 mg/mL of IgG) within 36 h of life of goat kids, observed high serum concentration of IgG on the fifth day of life, approximately 24 mg/mL, a value close to that seen in adult animals, approximately 31.6 mg/mL.
