Fat Metabolism in Growing Swine: A Review

Abstract: At birth, piglets have little body fat that can be mobilized. The influx of high-fat milk causes a rapid increase in body fat stores and a depression of lipogenic enzyme activity. Conversely, lipolytic enzyme activity increases after birth. Changing the fat intake of sucking piglets affects the amount of fat deposition. The length of the sucking period also influences body composition at weaning. Weaning produces a pronounced but temporary decrease in total body lipid, despite an increase in fat synthesis.

“…Although it is usually accepted that fatty acid synthesis is limited in suckling newborn mammals [4,15,38], the present data indicate that lipogenesis is not limited by enzyme activities or glucose transporter and that these parameters are regulated by early nutrition. The activities of lipogenic enzymes are lower in this study than in weaned pigs [3,28] but they are significant.…”

“…Body fat in the neonate is thought to be primarily derived from dietary fat since it is usually accepted that fatty acid synthesis is negligible in suckling newborn mammals [4,15,38]. Nevertheless, the detection of lipogenic enzymes in adipose tissue [27] and in skeletal muscle [28] of suckling pigs suggests that the activities of these enzymes may be significant for fatty acid synthesis.…”

“…Limiting the concentration of linoleic acid (C18:2n-6) in pig fat improves fat consistency, decreases the susceptibility to oxidation and development of undesirable flavor and reduces the incidence of technological problems, such as those related to water migration (López-Bote, 1998;López-Bote et al, 2002;Isabel et al, 2003). A reduction in C18:2n-6 concentration is achieved through the incorporation of saturated fats or other ingredients that enhance endogenous fat synthesis during the fattening diets period (Farnworth and Kramer, 1987;Wood et al, 2004;Duran-Montgé et al, 2008).…”

“…In sow-reared piglets the time between birth and weaning is one of rapid fat accretion (Farnworth and Kramer, 1987) when adipocytes increase in size and lipid content (Moody et al, 1978). By using an artifi-icial rearing system using milk replacer, in which the level and type of fat can be controlled, feeding regimes may be developed that optimize desired growth or compositional characteristics.…”
