Resum

L'objectiu d'aquest estudi era avaluar la deposició d'energia, nitrogen, greix i àcids grassos en pollastres d'engreix alimentats amb dietes que contenien diferents fonts d'oli vegetal. Quaranta femelles de pollets d'engreix van ser alimentades amb cinc dietes, amb diferents greixos [oli de coco, palma, oliva, soja (SO) i oli de llinosa (LO)] del 10% al 30-50 dies d'edat. Els animals que consumien la dieta LO presentaven el contingut més baix de greix corporal. No hi va haver diferències entre els tractaments pel que fa a l'equilibri de nitrogen. El major percentatge d'energia metabolitzable aparent es va obtenir amb la dieta LO. Tots els animals dipositaven més àcids grassos saturats i monoinsaturats del que digerien, però la quantitat d'àcids grassos poliinsaturats dipositats en els tractaments SO i LO era menor que la quantitat digerida. Aquests resultats indiquen que els pollastres que consumien les dietes altament poliinsaturats dipositaven menys greix a causa d'un guany inferior d'àcids grassos poliinsaturats.

abstract = "The objective of this study was to assess energy, nitrogen, fat and fatty acid deposition in broilers fed diets containing different vegetable oil sources. Forty female broiler chickens were fed five diets, with different fats [coconut, palm, olive, soybean (SO) and linseed oil (LO)] at 10\% from 30 to 50 days of age. The animals consuming the LO diet presented the lowest body fat content. There were no differences among treatments regarding nitrogen balance. The greater percentage of apparent metabolizable energy was obtained with the LO diet. All animals deposited more saturated and monounsaturated fatty acids than digested, however the amount of polyunsaturated fatty acids deposited in the SO and LO treatments was lower than the amount digested. These results indicate that chickens that consumed the highly polyunsaturated diets deposited less fat due to a lower gain of polyunsaturated fatty acids.",
