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.
Goat producers’ perception of climate change and adaptation strategies in the tropical dry forest of Northern Peru

Climate change affects countries worldwide, challenging economies and livelihoods. It negatively impacts food production due to temperature variability, irregular precipitation, frost, and drought, increasing pressure on agrosilvopastoral resources and reducing agricultural and livestock productivity. In Peru, the tropical dry forest, an ecosystem highly vulnerable to climate change, supports traditional goat farming, a primary livelihood for many, with a population of approximately 256,860 goats in Piura. This ecosystem is particularly sensitive to temperature and precipitation changes, which directly affect forage availability and livestock productivity. This study aimed to determine goat producers' perceptions and adaptation strategies to climate change in Marcavelica, Lancones, and La Brea. Data from 130 goat producers were analyzed using descriptive and multivariate statistics (principal component analysis, multiple correspondence analysis, and cluster analysis). Results showed that goat farming occurs predominantly in extensive systems (84.62%). Most producers (56.9%) acknowledged climate change, perceiving changes in temperature (69.9%), precipitation patterns (100%), soil productivity (79.2%), and water availability (50%). Four producer clusters were identified based on adaptive capacity: excellent (6.16%), good (23.08%), regular (75.38%), and poor (24.62%). Producers with higher education, associativity, and training demonstrated better knowledge and adaptive capacity. Climate change is evident in the dry forest ecosystem, negatively affecting goat farming. These findings underscore the importance of education, technical support, and associativity to enhance producers' resilience and sustain livestock production under climate variability.
Morphometric and phaneroptic characteristics of creole goats in the dry forest of Peru

The study aimed to describe morphometric and phaneroptic parameters in goat herds from the northern region of Lambayeque, Peru. A total of 295 goats over two years old, without evidence of crossbreeding with specialized breeds, were used. For each animal, 19 morphometric and eight phaneroptic measurements were recorded, and zoometric indices were calculated using a scale, measuring tape, and zoometric stick. This was performed using R software version 4.3.1. The results showed an average live weight of 41 ± 7.5 kg and a proportionality index of 99.6, highlighting their suitability for meat or dual-purpose production (IDT: 13.4, ICO: 88.7), adapted to the local environment. Regarding phaneroptic characteristics, monochromatic coat colors predominated in 55.6% of the animals, 43.7% were hornless (72.7% of the horns observed were parallel), 20.7% had beards, and 10.5% presented wattles. Additionally, 14.7% had supernumerary teats, and 46% of males displayed testicular bifurcation. In conclusion, the Creole goat of the Dry Forest in northern Peru is medium-sized, with robust limbs and a meat-production aptitude, as reflected by the proportionality index. It is also characterized by predominantly dark coats and parallel horns when present. These features demonstrate their adaptation to this environment and their potential for meat production.
