Livestock in the Peruvian Amazon region is mostly produced in areas considered degraded pasturelands and associated with deforestation. Silvopastoral systems (SPS) are an alternative for sustainable livestock production. This article aims to provide information about progress in the development of SPS in the Peruvian Amazon region during the last 2 decades and opportunities to develop it further at the national level. The geographical characteristics and climatic conditions of the Peruvian Amazon are described, followed by a review of the experiences with SPS in the 5 most relevant departments of the region. Constraints for implementation of SPS practices in the country and the current initiatives at regional and national level to promote and develop more sustainable livestock production in the region are presented. There is a large variation in SPS practiced along the different departments of the Amazon region. It is imperative that the Peruvian Government continues promoting SPS for recovering degraded lands through generating enabling conditions for farmers to adopt and/or scale up SPS.

(Instituto Nacional de Innovación Agraria (INIA), 2024-03-31) Durand Chávez, Luz Marlene; De Paz Hizo, Benjamín Alberto; Carrasco Chilón, William Leoncio
El Instituto Nacional de Innovación Agraria (INIA) pone a disposición la “Guía de manejo de botón de oro para sistemas ganaderos sostenibles en trópico”, que será de gran utilidad para los grandes y pequeños criadores de animales menores y mayores. En esta guía se encuentran datos relevantes referidos a la instalación y manejo del banco forrajero de botón de oro como alternativa tecnológica para el establecimiento de sistemas silvopastoriles intensivos en el trópico.

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).
