“…Previous research has suggested supplementing sows with fish oil during lactation may accelerate the maturation of the piglet immune system [18]. However, in agreement with Leonard et al [19], the present study observed no effect of oil type on piglet IgG blood serum concentrations at weaning.…”

This study investigated the effect of salmon oil in lactating sow diets and offering these diets in a phased dietary regimen to increase the energy density of the diet in late lactation. Sow and piglet productivity to weaning, the fatty acid profile of milk, piglet blood and tissues at weaning were the main parameters measured. Multiparous sows (n = 100) (Landrace × Large White) were offered dietary treatments from day 105 of gestation until weaning. Dietary treatments (2 × 2 factorial) included oil type (soya or salmon oil) and dietary regimen (Flat 14.5 MJ/kg DE diet offered until weaning or Phased 14.5 MJ/kg DE diet offered to day 14 of lactation then a second diet containing 15.5 MJ/kg DE offered from day 15 until weaning). Salmon oil inclusion increased the total proportion of n-3 fatty acids in colostrum (p < 0.001), milk (p < 0.001), piglet plasma (p < 0.01), adipose (p < 0.001), liver (p < 0.001) and muscle (p < 0.001). Increasing sow dietary energy level in late lactation increased the total n-3 fatty acids in milk (p < 0.001), piglet adipose (p < 0.01) and piglet muscle (p < 0.05). However, piglet growth to weaning did not improve.

“…In contrast, FO supplementation induced an increase in mRNA expression of the pro-inflammatory cytokines, IL-6 and IL-1α in colonic tissue and tended to increase mRNA abundance of the anti-inflammatory IL-10 in ileal tissue. Lou et al ( 52 ) reported that dietary provision of FO during the PW phase induced an up-regulation of splenic IL-6 and IL-10 mRNA expression in pigs. Although IL-6 is generally considered a pro-inflammatory cytokine, IL-6 plays an important role in mediating B-cell activation and antibody production ( 53 ) .…”

Effect of dietary seaweed extracts and fish oil supplementation in sows on performance, intestinal microflora, intestinal morphology, volatile fatty acid concentrations and immune status of weaned pigs

A 2 £ 2 factorial experiment (ten sows per treatment) was conducted to investigate the effect of maternal dietary supplementation with a seaweed extract (SWE; 0 v. 10·0 g/d) and fish oil (FO; 0 v. 100 g/d) inclusion from day 109 of gestation until weaning (day 26) on pig performance post-weaning (PW) and intestinal morphology, selected microflora and immune status of pigs 9 d PW. The SWE contained laminarin (10 %), fucoidan (8 %) and ash (82 %) and the FO contained 40 % EPA and 25 % DHA. Pigs weaned from SWE-supplemented sows had higher daily gain (P¼ 0·063) between days 0 and 21 PW and pigs weaned from FO-supplemented sows had higher daily gain (P,0·05) and gain to feed ratio (P,0·01) between days 7 and 14 PW. There was an interaction between maternal SWE and FO supplementation on caecal Escherichia coli numbers (P,0·05) and the villous height to crypt depth ratio in the ileum (P,0·01) and jejunum (P,0·05) in pigs 9 d PW. Pigs weaned from SWE-supplemented sows had lower caecal E. coli and a higher villous height to crypt depth ratio in the ileum and jejunum compared with non-SWE-supplemented sows (P,0·05). There was no effect of SWE on E. coli numbers and villous height to crypt depth ratio with FO inclusion. Maternal FO supplementation induced an increase in colonic mRNA abundance of IL-1a and IL-6 (P,0·05), while SWE supplementation induced an increase in ileal TNF-a (P,0·01) and colonic TFF3 mRNA expression (P,0·05). In conclusion, these results demonstrate that SWE and FO supplementation to the maternal diet influenced the gastrointestinal environment and performance of the weaned pig.

“…It is reported that dietary FO supplementation could exert a beneficial effect on anti-inflammatory activity [36,37]. Moreover, maternal FO supplementation potentiated an anti-inflammatory response in suckled piglets and accelerated the piglet immune system maturation [38,39]. Also, a recent study demonstrated that maternal supplementation with FO modulated inflammation-related microRNAs and genes in sucking lambs [40].…”

This study aimed to investigate the effects of maternal lipopolysaccharide (LPS) challenge and dietary fat sources on colostrum quality and inflammatory response in sows. Sixty Landrace × Yorkshire sows were randomly assigned to three dietary treatments supplemented with 3% soybean oil (SO), 3% coconut oil (CO) or 3% fish oil (FO), respectively, from Day 90 of gestation until parturition. On Day 112 of gestation, half the sows from each dietary treatment were challenged with LPS (10 μg/kg BW) or saline. The results showed that maternal LPS challenge decreased colostrum yield and dry matter content. A similar pattern of changes was observed for body weight gain and colostrum intake in piglets from LPS-challenged sows. Maternal LPS challenge increased the levels of tumor necrosis factor α (TNFα), interleukin 1β (IL1β) and IL6 in colostum, and the mRNA abundance of IL6, IL1β and TNFα and the phosphorylation level of p65 in mammary glands. However, the responses of these variables to LPS treatment were lower in sows fed a FO diet. In conclusion, maternal immune challenge reduced the growth performance of piglets by decreasing colostrum yield and intake by piglets, and dietary supplementation with FO in sows attenuates the LPS-induced inflammatory response in mammary glands.
