Pigs with access to straw either as bedding and/or via their diet deposit less fat in their belly than pigs without access to straw (Trezona et al, 2007). There are at least two possible mechanisms for this. First, if pigs consume straw in addition to their food the energy density of their total intake may be less and this may depress their voluntary energy intake and lower the deposition of fat. Second, if pigs lie on straw that insulates them better they may respond by depositing less fat in the areas that are in contact with the ground. If less fat is deposited because endogenous synthesis is reduced then it is likely that the fatty acid (FA) profile of the fat will change and become less saturated.
