Rumen development and weight gain in lactating calves is a problem in weight gain which leads to increased cost of production. The objective of the present study was to evaluate the effect of tributyrin inclusion in milk fed to lactating calves up to 30 days of age on rumen development and weight gain. Calves were not used because the animals would be slaughtered at the end of the study and their high productive value made this option impossible. Nine lactating calves were used, which were distributed in three treatments, T0: base diet without tributyrin in milk, T1: base diet with 5g of tributyrin in milk and T2: base diet with 10g of tributyrin in milk. The work was carried out at 3404 meters above sea level in the DJ dairy located in the province of Julcán, department of La Libertad, Peru. Our results showed that the use of tributyrin increased the length of rumen papillae (p=0.0001) and omasal papillae (p<0.0001), significantly increased the relative rumen weight (p=0.0116) and omasum (p=0.0037). However, it did not affect the epithelial thickness of the rumen and omasum (p>0.05) and significantly reduced the relative weight of the reticulum (p=0.0013) and abomasum (p<0.0001). The use of tributyrin significantly improved (p<0.05) average weight gain and daily weight gain; however, it did not statistically affect final weight or feed intake (p>0.05). Therefore, we conclude that the inclusion of tributyrin in milk increases rumen development and does not negatively affect the performance of lactating calves up to 30 days of age
