Pasture-based livestock systems in the Peruvian Amazon region are characterized by degraded pastureland and their association with deforestation processes. Silvopastoral systems are an alternative to traditional tree-less pastures that has been recently developed and studied in this region of the country. This chapter provides information about the progress in the development of silvopastoral systems (SPS) in the Peruvian Amazon and the perspectives at national level for the next years. To accomplish these goals, we first review the experiences of establishing and evaluating SPS in five departments of the Peruvian Amazon. Then, we present a list of barriers for the implementation of SPS practices in the country and the current initiatives at the regional and national levels to promote and develop sustainable livestock production systems in the Peruvian Amazon region. We conclude that barriers such as available technology, capacity building, market access and associativity, financing and favorable environmental conditions need to be cleared first for the promotion and successful implementation of SPS in the Peruvian Amazon. Moreover, some of them need to be assumed by the producers, and others by the State at local, regional and national levels.

The objective of this study was to evaluate the growth (cm), yield (kg/m2), crude protein (CP %), crude fiber (CF %), ether extract (EE %), NDF (%), ADF (%), gross energy (GE kcal/kg), ELN (%), Ash (%), and in vitro digestibility (IVD %) of Brachiaria mutica grass; under three silvopastoral systems, guava (Inga edulis), poplar (Populus alba), and eucalyptus (Eucalyptus globulus labill) and a treeless system (TS) in the northeast of peru. These were analyzed under a completely randomized design (CRD) with four treatments and four repetitions, and the results were analyzed by analysis of variance (α = 0.05%) and Tukey’s means test (p ≤ 0.05). The SPS of guava showed higher growth at 30 days (59.57 cm), and the there was no difference between systems at 45 (98.43–107.14 cm), 60 (138.86–146.57 cm), and 75 days (159.81–165.67 cm); the highest yield at 30 days was for SPS with guava (0.41 kg/m2), at 45 and 60 days there was no difference (1.01–1.15 and 1.57–1.76 kg/m2), and at 75 days the highest yield was from TS (2.88 kg/m2); the nutritional composition was evaluated in two cut-off frequencies (30 and 75 days); for 30 days, the SPS with guava had a higher value for CP (16.03%), IVD (68.13%), and GE (4502 kcal/kg); the SPS with eucalyptus had a higher percentage for CF (21.08), NDF (33.17), FDA (56.42), and ash (7.74); the highest EE content was in the SPS with poplar (2.46%) and the TS presented the highest percentage of ELN (50.88); for 75 days, the SPS with guava presented a higher value for CP (13.61%), FDA (36.78), and GE (4504.33 kcal/kg), the SPS with eucalyptus had a higher percentage for CF (23.51) and ash (6.42), and the the SPS with poplar had the highest percentage of EE (2.24), ELN (59.18) FDN (62.67), and IVD (56.59).
