The effect of porcine manure silage supplementation on productive indicators of Hartón del Valle heifers was evaluated. An Irresistibly Random design was used, distributive normality tests, analysis of variance and Tukey test were applied. The animals were randomly assigned to two experimental groups. Both groups consumed forage purple king grass (Pennisetum purpureum CV King grass) and silage supplied to heifers contained two levels of inclusion of manure 15% (T1) and 30% (T2). Twelve weaned females were selected from the Zanjón Hondo line, with a mean weight of 218 kg ± 6 kg, of 12 months of age, where were determined for a period of 45 days, productive indicators of consumption, weight change and feed conversion. The two levels of supplementation with porkase did not affect (P>0.05) voluntary dry matter intake (CVMS) 6.58 (T1) and 7.06 (T2) kg/d.m./animal/día. However, there were differences (P<0.05) in daily weight gain, which were 0.53 for T1 and 0.38 kg / day for T2. Feed conversion was estimated at 11.66 for T1 and 18.89 for T2 (P<0.05). It is concluded that the productive indicators of Hartón del Valle heifers are satisfactory by incorporating 15% of dehydrated pig manure in silage as the supplementary feed in the period of rising.
