The objective of the present study was to evaluate the productive potential, acceptance and preference of three tropical forage legumes and their effectiveness to improve the nutritional status of growing heifers from protein supplementation using a protein bank. This study was carried out at the Selva Regional Development Institute (IRD-Selva), belonging to the La Molina National Agrarian University (UNALM), located in the Banda de Shilcayo district, Tarapoto province, San Martín region. To achieve the general objective, 3 experiments were carried out. 1) Establishment and productivity of three legumes (Stylosanthes guianensis, Centrosema macrocarpum and Arachis pintoi) with phosphorus supplementation. 2) Acceptance and preference in the consumption of forage legumes in calves. 3) Heifer growth rate in response to protein bank supplementation. In the legume establishment, emergence (%), plant height (cm), soil cover (%), Leaf/Stem ratio, forage availability (KgMS/ha), and presence of pests or diseases were evaluated. In acceptance and preference, the intake rate (g/min) was evaluated. In the third experiment, the availability of forage in the pastures and protein bank, activity budget, nutritional values of the diet and growth rate (g LW/day) were evaluated. The results were: 1) Stylosamthes guianensis cv and Centrosema macrocarpum cv were easier to establish and achieved greater productivity than Arachis pintoi, likewise the species presented a significant positive response to phosphorus fertilization. 2) A. pintoi and S. guianensis presented greater acceptance and preference. 3) The heifers with access to S. guianensis as a protein bank presented a gain of 481g/day and 421g/day for the group without access to the protein bank. It is concluded that the use of Stylosanthes guianensis as a protein bank significantly improved energy and crude protein intake, resulting in a greater increase in the growth rate.
