“…Piglets suckling from sows consuming the high-18:3n-3 diet had higher total lipid levels of 18:3n-3 and 22:6n-3 in the plasma, liver, and brain, whereas 20:4n-6 was decreased in all of these tissues except the brain. This is consistent with previous findings of piglets suckling from sows consuming fish oils and receiving 18:3n-3 from artificial formula, but has not been reported previously in pigs suckling from sows receiving 18:3n-3 supplementation (16)(17)(18)(19)(20)(21)(22)(23)(24). Rat pups suckling from dams consuming a high-18:3n-3 diet have lower brain total lipid 20:4n-6 with no changes in brain or whole body 22:6n-3 (28).…”

“…In contrast to what has been reported in rats (28), but similar to what has been observed with sows consuming fish oil and piglets consuming 18:3n-3 (16,18,20,22), this study suggests that during pregnancy and lactation, 18:3n-3 can increase both the 18:3n-3 and 22:6n-3 content of the piglet tissues.…”

“…Several studies have reported that feeding artificial formula rich in 18:3n-3 to piglets increases the n-3 PUFA composition of the piglet tissues (19)(20)(21). In addition, several studies have reported that pigs born to sows consuming fish oil during pregnancy have an increased n-3 PUFA content (16,(22)(23)(24). However, it is not known whether a raised 18:3n-3 intake in the sow affects n-3 PUFA accumulation in the tissues of the suckling piglet.…”

alpha-Linolenic acid (18:3n-3) is a precursor to DHA (22:6n-3), which is essential for normal growth and development in the infant. This study was undertaken to assess how a raised 18:3n-3 intake in sows affects the n-3 PUFA content of the suckling piglet. Sows consumed a high-18:3n-3 or control diet (n-3 PUFA/n-6 PUFA, 0.5 vs. 0.05, respectively) for 10 d prior to parturition and for 14 d postpartum. Piglets suckled from their mothers until 14 d of age, when they were sacrificed. Sows consuming the high-18:3n-3 diet had 141% more 18:3n-3 and 86% more 22:6n-3 in their milk compared to control sows. There was no difference in the proximate composition of the piglets. The n-3/n-6 PUFA ratio was 82% higher in the milk of sows consuming the high-18:3n-3 diet compared to controls. Piglets suckling from sows consuming the high-18:3n-3 diet had 423% more 18:3n-3 in the carcass as well as a 460% higher n-3/n-6 PUFA ratio than controls. The piglets suckling from sows consuming the high-18:3n-3 diet had 333% more 18:3n-3 and 54% more 22:6n-3 in the liver, as well as a 114% higher n-3/n-6 ratio than control piglets. Piglets suckling from sows consuming a high-18:3n-3 diet also had 24% more 22:6n-3 and a 33% higher n-3/n-6 ratio in the brain compared to control piglets. A high 18:3n-3 intake in the sow increases not only the 18:3n-3 but also the 22:6n-3 content of sow's milk and the tissues of the suckling piglet.

“…There are several reasons to suggest that colostrum consumption had little or no effect on the composition of piglet tissue fatty acids. First, in a subsequent study (Rooke et al 1998) in which colostrum consumption was prevented, similar changes in tissue composition were observed. Second, when birth order within a litter and time from sucking to slaughter, both of which would be indices of colostrum intake, were included as covariates in the ANOVA of the effect of diet on tissue composition, these covariates were not significant.…”

To investigate whether long-chain n-3 polyunsaturated fatty acids could cross the porcine placenta in late pregnancy and alter neonatal piglet tissue composition, multiparous sows (seven per diet) were fed on diets containing a supplement (30 g/kg) of either soyabean oil or tuna oil for the last 21 d of pregnancy and the first 7 d of lactation. The proportions of all fatty acids, except 18:1n-7, differed between diets: in particular, the tuna-oil-containing diet supplied more 22:6n-3 and less 18:2n-6 fatty acids than the soyabean-oil-containing diet. The proportions of n-3 fatty acids, particularly 22:6n-3 (g/100 g total fatty acids) in sow plasma, colostrum and milk were increased and the proportion of 18:2n-6 was decreased by feeding tuna oil. Piglet tissue n-3 fatty acid proportions (particularly 22:6n-3), obtained shortly after birth, were increased in piglets born to tuna-oil-fed sows compared with progeny of soyabean-oil-fed sows. The increase in the proportion of n-3 fatty acids (g/100 g total fatty acids) in piglet tissues as a result of tuna-oil feeding, compared with soyabean-oil-feeding, was in the order plasma>liver>erythrocytes>spleen>brain>retina. Piglets born to tuna-oil-fed sows had a lower viability score at birth than the progeny of soyabean-oil-fed sows. The proportions of long-chain n-3 fatty acid in tissues of new-born piglets were increased by feeding tuna oil to the sow in late pregnancy; however no improvements in piglet viability were observed.
