“…Previous studies carried out on forced etiolated Belgian endive showed linoleic acid (C 18:2) as the most abundant fatty acid, and reported slightly higher total fatty‐acid content compared to the data in the present study on chicons .…”

The fatty‐acid contents of five chicory cultivars commonly produced in Slovenia (‘Treviso’, ‘Verona’, ‘Castelfranco’, and autochthonous ‘Anivip’ and ‘Monivip’) were investigated. Mineral and organic fertilisers were used to produce the leaf mass for analysis. Hydroponic forcing of developed chicory roots was performed in three nutrient solutions with nitrogen, phosphorus and/or potassium at three different concentrations. The fatty‐acid analysis with gas chromatography (GC) revealed the contents of the C 16:0, C 18:0, C 18:1, C 18:2, C 18:3 and C 20:0 fatty acids. The total fatty‐acid content of the chicory produced by conventional and organic practices ranged from 170 to 500 mg/100 g fresh weight, and of the hydroponically forced chicons, from 60 to 160 mg/100 g fresh weight. The highest fatty‐acid content for both the chicory and chicons was α‐linolenic acid (≤63%), followed by linoleic (≤45%) and palmitic (≤24%) acids. The n‐6/n‐3 ratio was <1.0 for most of the samples. Practical applications: The study contributes to the knowledge of the impact of fertilisers on fatty acids profiles in chicory and chicon plants which has not been published in scientific literature so far. The aim of the present study was to evaluate the fatty‐acid composition of five chicory cultivars (red, red‐spotted, green) produced as cultivated (organically, conventionally) chicory leaves/ heads and as forced chicons. The present analysis demonstrates that the majority of the fatty acids in chicory and chicon consist of the PUFAs, among which the main ones are α‐linolenic acid (C 18:3, n‐3) and linoleic acid (C 18:2, n‐6). The fertilizers significantly impact fatty acid formation. The chicory and chicon both have an n‐6/n‐3 ratio < 1 and they thus represent a food that follows the current nutritional recommendations.

“…MGDG = monogalactosyldiacylglycerol; DGDG = digalactosyldiacylglycerol; PC = phosphatidylcholine; PE = phosphatidylethanolamine; PG = phosphatidylglycerol; PI = phosphatidylinositol; SL = sulpholipid (sulphoquinovosyl diglyceride).

Nichols (1963) reported that lipid classes are found in different proportions in different plant organs (i.e., leaves versus stems), with leaves having a higher GL content than stems.…”

“…Hay evidencia de que metabolitos secundarios presentes en plantas forrajeras no gramíneas, pueden limitar la biohidrogenación ruminal (Khiaosa-Ard et al, 2009) y la producción de metano (Jayanegara et al, 2011;Tan et al, 2011). Adicionalmente, existe variación en la composición lipídica de los forrajes frescos (Krebsky et al, 1996;Addis et al, 2005;Cabiddu et al, 2009), que puede afectar la cantidad de ATV producido en el rumen.…”

El objetivo del presente trabajo fue determinar el efecto de los forrajes sobre los ácidos grasos de cadena larga, fermentación ruminal y producción de metano de un sistema silvopastoril intensivo de Leucaena leucocephala. La investigación se desarrolló en el laboratorio NUTRILAB–GRICA, perteneciente a la Facultad de Ciencias Agrarias, de la Universidad de Antioquia, Medellín–Colombia, en julio del 2013. Se utilizó la técnica de producción de gas in vitro, utilizando como sustrato de fermentación las gramíneas (C. plectostachyus y/o M. maximus cv. Tanzania) y leucaena (L. leucocephala), solas o en sus combinaciones, con una relación forraje:concentrado 70:30 y gramínea: leucaena 56:14, para un total de siete tratamientos. No se encontró efecto de los forrajes (p>0,05), sobre el contenido de ácido linoleico conjugado (ALC, C18:2 c9t11) o ruménico en la digesta. La inclusión de 14% de leucaena aumentó el contenido de ácido linoleico (C18:2 c9, 12) y linolénico (C18:3 c9, 12, 15) en el alimento y de transvaccénico (ATV, C18:1 t11), esteárico (C18:0), linoleico y linolénico en la digesta (p<0,05), y no afectó la cinética de fermentación, digestibilidad de la materia seca (MS), pH, total y proporción de ácidos grasos volátiles, ni redujo la producción de metano. Las gramíneas, C. plectostachyus y M. maximus, se comportaron similar en las variables evaluadas (p>0,05). Los sistemas silvopastoriles pueden ser una opción para aumentar los ácidos grasos benéficos en la leche.
