| Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet. The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous enzymes, provided from live prey, are necessary for early stages. The organogenesis of marine fish larvae is not completely achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental changes over... |

| The feasibility of fish oil (FO) replacement by vegetable oils (VO) was investigated in gilthead sea bream (Sparus aurata L.) in a growth trial conducted for the duration of 8 months. Four isolipidic and isoproteic diets rich in plant proteins were Supplemented with L-lysine (0-55%) and soya lecithin (1%). Added oil was either FO (control) or a blend of VO, replacing 33% (33VO diet), 66% (66VO diet) and 100% (VO diet) of FO. No detrimental effects on growth performance were found with the partial FO replacement, but feed intake and growth rates were reduced by about 10% in fish fed the VO diet. The replacement strategy did not damage the intestinal epithelium, and massive accumulation of lipid droplets was not found within enterocytes. All fish showed... |

| El objetivo de esta reseña fue destacar la importancia que tiene la presencia de las grasas y los aceites vegetales en la dieta para niños. En el trabajo se exponen las características fundamentales de ambos grupos de lípidos. Se compara la grasa láctea y la grasa materna en cuanto a composición, haciendo énfasis en esta última debido a que los alimentos para infantes deben mantener la relación de ácidos grasos esenciales en el mismo orden en que se encuentran en la grasa materna. Se resumen los requerimientos de grasa del niño en distintas etapas de su vida, la composición de los aceites vegetales más utilizados en la elaboración de los alimentos, así como algunos aspectos a tener en cuenta al seleccionar una grasa para utilizar en la alimentación infantil. |
