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.

Peruvian Creole goats (PCGs) represent a unique genetic resource shaped by adaptation to diverse environments and traditional breeding practices. In this study, we performed a genomic analysis of six regional populations (Ancash, Ica, Lambayeque, Lima, Piura, and Tumbes) using high-density SNP genotype data. Principal component analysis revealed a moderate genetic structure, with the Ica population showing clear separation and northern populations exhibiting overlap. Runs of homozygosity were predominantly short, and specific regions on chromosome 6 were shared across populations. Inbreeding coefficients were generally low, with Ancash showing the highest values. Linkage disequilibrium decayed rapidly over genetic distance, especially in Piura, indicating higher genetic diversity. Estimates of effective population size revealed decreasing trends across populations, with Piura maintaining the largest recent population size. These findings offer valuable insights into the population structure of Peruvian Creole goats, providing guidance for conservation and sustainable breeding efforts.

Optimizing harvest stage and drying time to enhance yield and nutritive quality of whole-plant Tithonia diversifolia forage meal in arid tropics
(Frontiers Media SA, 2025-09-19) Temoche Socola, Victor Alexander; Sessarego Davila, Emmanuel Alexander; Rodríguez Vargas, Aníbal Raúl; Vásquez García, Cesar Alejandro; Riojas, Joel; Ruiz Chamorro, José Antonio; Cruz Luis, Juancarlos Alejandro
Introduction: Tithonia diversifolia, also known as Mexican sunflower, is a tropical shrub with high forage potential, but limited information exists on the optimal harvest stage to balance yield and nutritional value. Methods: A 3 × 3 factorial design was implemented under tropical dry forest conditions in northern Peru, combining three regrowth stages (30, 45, and 60 days) with three plant fractions (leaf, stem, and leaf–stem mixture), with four replicates per treatment. Agronomic traits, dry matter yield, proximate composition, and in vitro dry matter digestibility (IVDMD) were evaluated. Results: Biomass yield increased significantly with harvest age, reaching 11.93 kg fresh weight and 3.45 kg dry matter per plant at 60 days, although with reduced nutritional quality due to a higher stem proportion. Leaves harvested at 30 days had the highest crude protein (16.5%) and soluble carbohydrates (48.2%) with the lowest crude fiber (19.3%). In contrast, the 45-day leaf samples achieved the highest IVDMD (62.34 ± 1.42%). A strong positive correlation was observed between leaf area and biomass yield (r = 0.93), and a moderate negative correlation with digestibility (r = –0.42). Discussion: Harvesting at 45 days provided the best compromise between biomass production and nutritional value. These findings highlight the potential of T. diversifolia as a strategic forage alternative for sustainable feeding systems in tropical dry environments.
Seasonal and dietary effects on the hematobiochemical parameters of creole goats in the Peruvian Andes
(MDPI, 2025-07-23) Rodriguez Vargas, Anibal Raul; Sessarego Davila, Emmanuel Alexander; Castañeda Palomino, Katherine; Ormachea Sanchez, Huziel Héctor; Trillo Zarate, Fritz Carlos; Temoche Socola, Victor Alexander; Ruiz Chamorro, José Antonio; Cruz Luis, Juancarlos Alejandro
Creole goats have adapted to the harsh Andean environment, yet the physiological impacts of high-altitude production systems remain underexplored. This study assessed seasonal and dietary influences on the hematological and biochemical profiles of 45 Creole goats in the Peruvian Andes. The animals were assigned to three diets: D1 (grazing), D2 (grazing + 2000 g hay), and D3 (grazing + 400 g concentrate), across rainy and dry seasons. Biweekly blood sampling measured urea, cholesterol, total protein, albumin, ALP, ALT, WBCL, NeuP, LymP, HGB, and MCV. Season exerted the strongest influence (p < 0.001), with modest dietary effects and a consistent effect of sampling time. Urea, total protein, and albumin increased during the rainy season, though only urea responded significantly to diet. Leukocytosis rose in the dry season and with higher-protein diets, suggesting heightened immune activation under environmental stress. Hemoglobin peaked in the rainy season and early sampling, indicating better oxygenation. MCV and body weight were higher in the dry season, with weight unaffected by diet. These results underscore the complex interplay of environmental and nutritional factors in shaping goat physiology at high altitudes, emphasizing the importance of dynamic modeling in sustainable Andean livestock systems.
Short Communication: Prediction of body weight using morphometric measurements in Creole goats from Peru
(Society for Indonesian Biodiversity, 2025-07-15) Paredes Chocce, Miguel Enrique; Sessarego Davila, Emmanuel Alexander; Tafur Gutierrez, Lucinda; Temoche Socola, Victor Alexander; Salinas Marco, Jorge; Acosta Granados, Irene Carol; Ruiz Chamorro, Jose Antonio; Cruz Luis, Juancarlos Alejandro; Trillo Zarate, Fritz Carlos
Goats are an important component of smallholder family farms along the coast and highlands of Peru. The weight of an animal is an important indicator of the production and economy of farmers in rural areas. Therefore, this study aimed to develop predictive models for Body Weight (BW) using Morphometric Measurements (MM) of Creole goats (Capra hircus) in Perú. BW and five MM were collected from 356 goats from the coast and highlands of Peru. Variables were analyzed using correlation and stepwise regression analysis to select the best model based on the coefficient of determination (r²), adjusted r², Residual Standard Error (RSE), and Akaike Information Criterion (AIC) using the RStudio statistical software. The highest correlation was found between BW and TG (0.76), followed by RW (0.67), and RH (0.65). The combinations of MM selected as predictors of BW by stepwise regression were TG, RH, and RW, with r² 0.640. The selected candidate model met all established tests and, upon validation, reached an r² of 0.66 (p<0.001), indicating that the model can adequately predict the BW of Peruvian Creole goats and serve as a practical tool to support selection programs, feeding strategies, and market decision-making in smallholder systems.
