Goat production in the dry forest of northern Peru is essential for rural livelihoods but remains poorly characterized regarding its productivity and sustainability. This study used multivariate techniques—a multiple correspondence analysis (MCA), principal component analysis (PCA), factor analysis of mixed data (FAMD), and hierarchical cluster analysis (HCA)—to analyze data from 284 producers in Tumbes, Piura, and Lambayeque. Surveys captured 48 variables (41 qualitative, seven quantitative) on productivity, socioeconomics, and management. The MCA explained 22.07% of the variability in two dimensions, while the PCA accounted for 63.9%, focusing on productivity and diversification. The FAMD integrated these variables, explaining 51.12% of variability across five dimensions, emphasizing socioeconomic and management differences. The HCA identified three clusters: cluster 1 featured intensive systems with advanced management and commercial focus, cluster 2 included extensive systems limited by water scarcity, and cluster 3 reflected semi-intensive systems with irrigation and diversified production. These findings provide a detailed understanding of goat systems in northern Peru, identifying opportunities to improve resource use and tailor strategies to enhance sustainability. The multivariate analysis proved effective in capturing the complexity of these systems, supporting productivity and improving livelihoods in rural areas.
Effects of conservation time and ingredient proportion on the nutritional composition and in vitro digestibility of Musa spp. silages for small ruminant feeding

This study evaluated the effects of conservation time and ingredient proportion on the nutritional composition and in vitro digestibility of Musa spp. silages intended for small ruminant feeding. A 3×3 factorial design was applied, considering three conservation periods (60, 90, and 120 days) and three ingredient proportions (100% fruit, 70% fruit–30% crop residues, and 50% fruit–50% crop residues). Silage samples were analyzed for dry matter, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract, ash, nitrogen-free extract (NFE), and in vitro dry matter digestibility (IVDMD). Ingredient proportion significantly affected CP content, which ranged approximately from 3.4 to 6.9% of dry matter, whereas IVDMD varied between 50.8 and 74.2%, with the highest values observed in silages produced with 100% fruit at 90 days of conservation (p < 0.05). NDF and ADF contents ranged from 30–40% and 15–35% of dry matter, respectively, showing a significant interaction between conservation time and ingredient proportion. Principal component analysis clearly discriminated treatments according to their nutritional composition and digestibility attributes. Overall, the results demonstrate that both conservation time and ingredient proportion play a decisive role in determining the nutritional and digestive quality of Musa spp. silages, supporting their potential use as a strategic feeding alternative for small ruminants in tropical production systems.
