“…In general, differences between subcutaneous fat and intramuscular fat were observed. This result is in agreement with the findings of Marchello et al (1983), but is in contrast to the results of Miller et al (1990) where no differences between subcutaneous and intramuscular fat were detected. Monounsaturated fatty acids (MUFAs) ( Table 9) corresponded mainly to oleic acid (Table 8) and were high in subcutaneous fat and belly intermuscular fat.…”

Dietary fat influences the physico-chemical properties of meat, and fatty acid (FA) composition may have implications on human health. The objectives of the experiment were to study tissue FA partitioning and the effect of dietary fat source on tissue FA composition. Seventy crossbred gilts (61.8 6 5.2 kg BW average) were fed one of seven treatments: a diet containing a very low level of fat (no fat (NF)) and six fat-supplemented diets (10%: tallow (T), high-oleic sunflower oil (HOSF), sunflower oil (SFO), linseed oil (LO), fat blend (FB: 55% tallow, 35% SFO, 10% LO) and fish oil blend (FO: 40% fish oil, 60% LO). Differential tissue FA depositions were observed, with flare fat being the most saturated, followed by intermuscular, and subcutaneous being the least saturated. Monounsaturated fatty acid (MUFA) deposition showed an opposite tissue pattern. Subcutaneous fat showed the highest MUFAs, intermuscular fat showed intermediate values and flare fat showed the lowest MUFAs. Intramuscular polyunsaturated fatty acid (PUFA) content was less susceptible to dietary treatment modifications compared with other depots. Significant tissue FA modifications were observed due to dietary treatments, mainly in diets rich in PUFA. The saturated fatty acids (SFA) were high in NF-fed and low in HOSF-fed animals, MUFA were high in HOSF-fed and low in SFO-, LO-and FO-fed animals, while PUFA were high in SFO-and LO-fed and low in HOSF-, T-and NF-fed animals. Pigs fed LO and FB showed detectable levels of EPA, which depended on the linolenic content of the diet. The only effective way to increase tissue DHA contents was to add DHA in the diet through FO feeding. Araquidonic acid was high in SFO diets and low in LO and FB diets, and also high in intramuscular fat compared with other tissues. EPA and DHA were also high in intramuscular fat compared with other fat depots. The deposition of oleic and linoleic acids depended on the composition of dietary fat, as their deposition varied between diets, even at similar levels of intake of each FA. The NF diet resulted in the greatest proportion of SFAs (palmitic and stearic) of all treatments tested. SFAs were less susceptible to modification than MUFA in response to the different PUFA levels supplemented in the diet. T resulted in less fat deposition in some of the fat depots and more in others, suggesting that T could partition fat differently among fat depots.

“…These results agreed with previous results obtained in the pig [1,20,25] and in rat adipose tissue ([25]; review by Chilliard [6]) but contrast with those obtained in the rodent liver ([25]; review by Chilliard [6]; review by Clarke and Jump [7] Clarke and Jump [7]). Buller and Enser [2] [16,20]. This lower percentage of oleic acid could be related both to the lower oleic acid content of diet M and to the lower A9-desaturase activity in the adipose tissue of pigs fed diet M.…”

-The effects of three diets were compared: a high linoleic acid diet (diet M containing 4 % maize oil), diet T containing 4 % beef tallow, and C, a conventional control diet, on A9-desaturase activity and lipogenesis in pig subcutaneous adipose tissue. Diet M increased lipogenesis (estimated from the activities of acetyl-CoA-carboxylase, malic enzyme and glucose-6-phosphate dehydrogenase), and decreased A9-desaturase activity, in comparison to the other diets. Linoleic acid content was higher in the pigs fed diet M than in the other pigs (amounting to 26 % of total tissue fatty acids versus 15 %, respectively). The lower monounsaturated fatty acid content in adipose tissue of pigs fed diet M compared to pigs fed other diets could be associated with the lower A9-desaturase activity and the lower oleic acid content of diet M. The present study suggests that A9-desaturase could be involved in the regulation of monounsaturated fatty acid con-

Efecto de la dieta de cerdos ibéricos sobre la composición en ácidos grasos del tejido adiposo y muscular Effect of diet on the fatty acid composition of adipose and muscular tissue in Iberian pigs Se ha estudiado la composicion en £cidos grasos de la fracci6n total, apolar y polar de la grasa procedente del tejido adiposo y muscular de cerdos ib6ricos alimentados en regimen de montanera, recebo o cebo. En el tejido muscular, los acidos grasos mayoritarios de la fraccion total y apolar fueron C,,, (39-5T'/.,), CIOII (21-27'X.), 0,~(11-21&dquo;..), C1H2 7 (3-7 m ~~) y C1H:1 (1,7-5,-!'~';.), Sólo se observaron diferencias significativas en algunos de ellos. En la fracción de lipidos totales del tejido muscular, se observaron diferencias significativas (y ~ 0,05) entre los tres lotes para el Clf> 1 y para el C181 y el C1H:1I entre el lote cebo y los otros dos. En el caso de la fracci6n total del tejido adiposo, las diferencias significativas afectaron al C1hl y CIH.:> entre los tres lotes; para el Clh y CIH solo se observaron entre el lote montanera y los otros dos. En la fracción apolar y polar las diferencias entre lotes fueron menos marcadas yue en la fracc16n total. A pesar de estas diferencias debidas sin duda a la dieta, no se lograron clasificaciones correctas del 100% cuando se aplic6 el an6lisis discriminante por pasos sucesivos.Pall1bms ilaur: cerdo iberico, Acidos grasos, dieta, análisis discriminanteThe fatty acid composition of total, apolar and polar lipid fractions from adipose and muscular tissues of Iberian pigs was determined.
