Calibration and validation of the Mini-fiber EC image analysis instrument mean fiber diameter through direct or primary measurements
Abstract The Minifiber EC (MFEC) is a portable instrument for measuring the diameter of animal fibers. Its accuracy and precision have been estimated but by comparing its measurements with those of laboratory devices that had been calibrated on other devices in turn, not on a direct or primary measure of diameter. This work attempts to [...]
Development and preliminary validation of an automatic digital analysis system for animal fibre analysis
Conclusion An advanced driver assisted system (ADAS) called FIBER-EC was designed and developed. It is capable of performing AF, SDAFD, CVAFD, CF, PF and SF, derived in farm conditions, with a system of computer vision, implemented and associated with a mechanical structure for generating displacement of a sample holder in the XY plane. Environmental temperature [...]
Estudio de la diferencia post y pre descerdado de cinco características textiles de la fibra de llama (Lama glama) Cha’ku
RESUMEN Se tomaron muestras de 10 g de 7 regiones corporales (Cuello, Vellón anterior, Vellón central, Vellón posterior, Miembro anterior, Miembro posterior y Barriga), de lado izquierdo y derecho de 15 llamas Ch'aku adultas del Centro de Investigación y Desarrollo de Camélidos Sudamericanos - Lachocc de la Universidad Nacional de Huancavelica, ubicado entre 4100 y [...]
Effect of genotype and sex on fiber growth rate of alpacas for their first year of fleece production
RESUMEN La venta de la fibra de alpaca constituye el principal ingreso económico para miles de familias que viven en la zona altoandina de Perú. Por otro lado, la fibra que crece durante el primer año de vida de los animales resulta ser la más valorada, sin embargo en la actualidad, existe muy poca información [...]
Prediction of alpaca fibre quality by near-infrared reflectance spectroscopy
Prediction of alpaca fibre quality by near-infrared reflectance spectroscopy Abstract Rapid and efficient methods to evaluate variables associated with fibre quality are essential in animal breeding programs and fibre trade. Near-infrared reflectance spectroscopy (NIRS) combined with multivariate analysis was evaluated to predict textile quality attributes of alpaca fibre. Raw samples of fibres taken from male [...]
