Effect of Different Dietary Lipid Sources on Growth Performance, Nutrient Digestibility, and Intestinal Health in Weaned Pigs

To investigate the effects of lipid sources on growth performance and intestinal health, 72 weaned pigs were randomly allocated to three treatments. Pigs fed with a corn–soybean meal diet containing 2% soybean oil (SO), or fish–palm–rice mixture (FPRO), coconut–palm–rice (CPRO). The trial lasted for 28 days; blood tissue samples collected. results showed that crude fat digestibility FPRO group was higher than SO CPRO groups (p < 0.05). also had dry matter, ash, gross energy 0.05); compared group, serum interlukin-6 (IL-6) concentration decreased. Interestingly, villus height in jejunum ileum, respectively Moreover, Lactobacillus abundance colon cecum Importantly, expression levels tight junction protein ZO-1, Claudin-1, Occludin duodenal ileal mucosa nutrient transporters such as CAT-1, PepT1, FATP1, SGLT1 improved epithelium functions, well reduced inflammatory cytokines, suggest mixed source deserves further attention.
