    Autor: Ibacache G., Antonio

    Serie Documental: Tierra Adentro

    N° Publicación: no. 63

    Con el propósito de determinar el contenido de aceite y la composición de ácidos grasos de los frutos de nuez mas interesantes para el norte chico, en el año 2003 se enviaron muestras de frutos de nogal (Serr), pecano (Wichita) y almendro (Non Pareil) del huerto de Llimpo (Salamanca, cuarta región) al Instituto de Nutrición y Tecnología de Alimentos (INTA) de la Universidad de Chile; el presente articulo presenta los resultados de los análisis

    Pasture type effects over beef quality: A comparison

    The beef is one of the main sources of nutrients for a balanced diet. In this context, several authors have reported that grass-fed beef presents low levels of intramuscular fat and high levels of polyunsaturated fatty acids. Some studies have noted that forage fatty acid content is variable between species and their varieties, and that can affect fatty acid profile in beef. The aim of this study was to evaluate beef quality from three different types of pastures in southern Chile. A group of 45 Holstein Friesian steers were finished in the spring months with three different types of pastures from temperate rainy climate: Improved pasture (P), Lolium perenne L.-based pasture (LT), and Lolium multiflorum Lam.-based pasture (LM). The steers were separated into groups of 15 for treatment. Nonsignificant differences were found in carcass measurements and P treatment showed a higher intramuscular content than LM treatment (2.26% vs. 1.42%) and greater presence of SFA: 42.4% vs. 40.3% reported in LM treatment. While LM presented a higher n-6 fatty acids: 4.42% related to P treatment: 3.13%. Regardless of the type of pasture, it can be confirmed that meat from pasture systems presents low intramuscular fat and a better ratio of n-6/n-3
