In a buffalo herd in Venezuela, absorption crosses to the Mediterranean breed have been carried out for 30 years. The semen used in the artificial insemination programs comes from Italy. Each year, the buffalo used are selected based on the available germplasm supply. A Pearson correlation analysis was conducted to determine the degree of association between the traits evaluated in the ANASB (Associazione Nazionale Allevatori Specie Bufalina) genomic index and the internal genetic evaluation carried out within the herd under study. The estimated genetic values of 10 buffalo with evaluated progeny were used; the number of offspring born ( ♂ and ♀) for each of them ranged from 12 to 154, and the number of completed lactations of their daughters was from 10 to 249 for the buffalo with the lowest and highest number of records of their daughters, respectively. The correlation analysis considered the estimated breeding value for weight at birth (WB), weaning weight adjusted to 270 days (W270), and milk production per lactation (MPL). The 2023 Buffalo and Bull Genomic Index of the ANASB, the RESA, and IgBMI indices were obtained for these same buffalo, in addition to the genetic estimates for milk (M), % protein (%P), % fat (%F), extremities (feet - EF) and mammary gland (MG). The correlation between MPL and M was high (0.80) and (p≤0.01). Negative correlations were obtained between MPL and %P, %F, and RESA with values of -0.25, -0.13, and -0.22, respectively. None of them present statistical significance. Although positive, the correlation between MPL with IgBMI, EF, and MG was low and insignificant (0.17, 0.03, and 0.16, respectively). The correlations of WB with the IgBMI and EF were 0.59 and 0.65, respectively (p≤0.05). The WB and W270 correlation were 0.76 (p≤0.05). The ranking of the ten buffalo by their estimated genetic value for milk in both tests, the first and second place coincided, and the last three. The data suggested that Mediterranean buffalo semen can be selected based on genetic indices for milk generated in Italy.
