O planejamento do uso e cobertura da terra visa subsidiar um manejo adequado da bacia hidrográfica com vistas a evitar a sua degradação. Para melhor entender e prever os sedimentos exportados têm sido proposto o software InVest (Integrated Valuation of Ecosystem Services and Tradeoffs) no módulo SDR (Sediment Delivery Ratio). O objetivo do estudo foi espacializar e estimar os sedimentos exportados em diferentes solos e usos na área de estudo da bacia hidrográfica do rio Iquiri (Ituxi) em Acrelândia- AC. As maiores taxas de sedimentos exportados foram em áreas de Argissolo vermelho amarelo com 267,19 Mg/ano em seguida com menores valores as áreas de Latossolo vermelho 53,72 Mg/ano e Argissolo vermelho 35,02 Mg/ano. As áreas de Argissolo vermelho amarelo com pastagem sem invasora e lavoura perene são mais susceptíveis a exportação de sedimentos. |

ABSTRACT: Two hundred seventeen grass-finished Braford steers were assessed by ultrasonic scanning and subsequently harvested with their pistol hindquarters fabricated into boneless wholesale cuts. The Longissimus thoracis muscle area and subcutaneous fat depths were measured. The objectives of this study were: 1) to develop prediction equations for weights of the pistol hindquarter and high-value commercial cuts, and 2) to estimate sample size needed for experiments comparing pistol hindquarter retail product weight using either physically or ultrasonically measured carcass traits. Carcass measurements explained 44 % to 94 % of the variation in weights of individual cuts, whereas, measurements that were made using ultrasound explained 42 % to 90 % of the variation in the weights. Models used to predict the weight of pistol hindquarter retail product with carcass measures and ultrasound measures showed high coefficient of determination (R2 = 0.92 and 0.97, respectively). Whether based on carcass or ultrasound measures, models used to estimate weight percentage of fat trimmed from the pistol hindquarter had lack of fit. In general, models for individual cuts weights that used traits measured with ultrasound as independent variables approached the accuracy of models using carcass traits. Thus, only slightly greater samples sizes were required to have equivalent power to detect differences in retail product weights using ultrasound measures. For experiments of equivalent power, differences in the number of animals required may be offset by avoiding costs for slaughter and fabrication. Keywords: cattle, carcass, models, ultrasound MenosABSTRACT: Two hundred seventeen grass-finished Braford steers were assessed by ultrasonic scanning and subsequently harvested with their pistol hindquarters fabricated into boneless wholesale cuts.
