The aími of this study was to compare the in vivo apparent protein digestibility method in rats and the ín vitro pepsin ( EC: 3.4.23.1) digestibility method; as weil as to determine the correlation between these two methods. Three protein sources used in commercial dog foods were assessed: Soybean mea¡ (HS), meat mea¡ (HC) and chicken mea¡ (HP); in addition, three commercial adult dog foods (Al, A2 and A3) as weil as three commercial puppy foods (C1, C2 and C3) were evaluated and sodium caseinate was used as a control group. For the in vivo assay, 60 twentythreedayo1d albino laboratory rats (Rattus norvegícus) were used; the in vítro method tested was the standard method used at the Biochemistry, Nutrition and Animal Feed Laboratory, in the Faculty of Veterinary Medicine, UNIVISM. Each ín vivo and in vitro assay was performed six times and the resuits were reported as means ± Standard Deviation. The ANOVA test was used and significance difference between means was identified using the Tukey Test (p<0.05); simple correlation and regression analyses were also used. As a result, the correlation coefficient between the in vivo and the in vítro methods was 0.94 (p<0.05); where the in vítro digestibility was statistically higher than the ín vívo digestibility. The regressíon equation was Y, ín vivo = 11.037 + 0.804 (X, ín vitro). it is concluded that there is a high correlation between both protein digestibility methods when assessing protein sources and commercial dog foads.
