ABSTRACT.- From a calibration trial involving computer tomography (CT) scanning and dissection of 45 lambs, a prediction equation was derived to estimate total internal fat weight in Scottish Blackface lambs from measurements taken on cross-sectional CT images. Using data from two cross-sectional images (at the hip and loin) internal fat can be predicted with relatively high accuracy (adjusted R2 = 62.2%, r = 0.79). The derived equation was then used to predict internal fat weights in a further 427 Scottish Blackface lambs from a separate trial. Phenotypic correlations were calculated between predicted internal fat weight and weights of total carcass fat, muscle and bone, predicted using previously derived equations. When considering absolute tissue weights, adjusted for fixed effects, internal fat showed the strongest positive correlation with carcass fat (0.58), followed by muscle (0.36), and then by bone (0.32). When tissue weights were adjusted for fixed effects and total carcass weight (so considering tissue weights relative to size), internal fat showed a lower correlation with carcass fat weight (0.36) and negative correlations with muscle (-0.35) and bone (-0.19). These results provide the basis for more complex studies of relationships (phenotypic and genetic) between internal fat in hill lambs and economically important traits, such as carcass composition and survival of lambs, and tissue levels in different depots in hill ewes.

Esta herramienta reúne en un solo lugar, de fácil acceso, literatura publicada sobre temas de interés, con énfasis en "Campo natural", además de otros temas relacionados.
Se proporciona un diagrama, donde luego de un breve diagnóstico de la situación del "Campo natural" y el uso del suelo, los usuarios tendrán opciones de acciones apoyadas por la literatura.
Este diagrama no está destinado a cubrir todas las situaciones posibles, pero proporciona un enfoque lógico para analizar los casos. Es una herramienta dinámica que permitirá añadir (o eliminar) literatura a lo largo del tiempo, con el fin de satisfacer las demandas de los usuarios. |
