Abstract

•Effect of maternal laminarin and fucoidan supplementation on pig performance was investigated.•Maternal laminarin supplementation increased villous height in the ileum of pigs post-weaning.•Maternal laminarin supplementation reduced intestinal cytokines mRNA of pigs post-weaning.•Maternal laminarin supplementation improved pig growth during grower-finisher period.

The study investigated the effects of maternal dietary supplementation (n 10 gilts/treatment) of laminarin (0 and 1.0 g/d) and fucoidan (0 and 0.8 g/d) from day 107 of gestation until weaning (day 24) on pig growth performance from birth to slaughter (n 10 pigs/treatment group), and aspects of intestinal health at weaning (n 7 pigs/treatment group) and day 8 post-weaning (PW) (n 7 pigs/treatment group). Pigs were individually penned during days 0–26 PW, and penned in groups of 10 (based on maternal dietary treatment) during days 26–117. There was an interaction between laminarin and fucoidan on sow faecal Enterobacteriaceae gene copy numbers (GCN) (P<0.05). Fucoidan-sows had increased faecal Enterobacteriaceae CGN compared with basal-sows (P<0.05). However, there was no effect on Enterobacteriaceae CGN when laminarin was combined with fucoidan. Piglets suckling the fucoidan-sows had shorter villus height (VH) and down-regulated SGLT1 mRNA in the ileum at weaning compared with those suckling the non-fucoidan-sows (P<0.05). Pigs from the laminarin-sows had longer VH in the ileum on day 8 PW compared with those from the non-laminarin-sows (P<0.05). Pigs from the laminarin-sows had IL-6 mRNA down-regulated in the colon at weaning and IL-8 down-regulated in the ileum on day 8 PW compared with those from the non-laminarin-sows (P<0.05). Pigs from the fucoidan-sows had increased body weight (BW) on day 26 PW compared with those from the non-fucoidan-sows (P<0.05). Pigs from the laminarin-sows had increased BW on day 67 and gain:feed ratio during days 26–117 PW compared with those from the non-laminarin-sows (P<0.05). In conclusion, maternal laminarin supplementation resulted in positive response in aspects of intestinal health PW and pig growth performance during the grower-finisher period.
