The aim of this study was to determine the correlation between the staple strength and the textile characteristics of black and brown fibres, as well as to evaluate the influence of colour, breed, location, age, and sex of alpaca on the staple strength properties. Staple strength was measured with the Staple Length & Strength instrument. Fibre characteristics were measured using an Optical-based Fibre Diameter Analyzer (OFDA 2000). Data did not show a normal distribution, as verified by the Shapiro-Wilk normality test. Spearman’s rank correlation coefficients between staple strength and fibre textile characteristics were calculated. The influence of colour, breed, location, age, and sex of alpacas on the staple strength properties were analysed separately by the Kruskal-Wallis rank sum test (α=0.05). The highest correlation was observed between peak force position and staple lengt...

Livestock in the Peruvian Amazon region is mostly produced in areas considered degraded pasturelands and associated with deforestation. Silvopastoral systems (SPS) are an alternative for sustainable livestock production. This article aims to provide information about progress in the development of SPS in the Peruvian Amazon region during the last 2 decades and opportunities to develop it further at the national level. The geographical characteristics and climatic conditions of the Peruvian Amazon are described, followed by a review of the experiences with SPS in the 5 most relevant departments of the region. Constraints for implementation of SPS practices in the country and the current initiatives at regional and national level to promote and develop more sustainable livestock production in the region are presented. There is a large variation in SPS practiced along the different departme...
