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.
Short Communication: Prediction of body weight using morphometric measurements in Creole goats from Peru

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.
