Weaned Pigs

One hundred eighty newly weaned pigs were used to inves tigate effects of feeding organic acids and herbal extracts on growth performance, gut morphology and microbiota, and immune response in newly weaned pigs during a 4-wk period. There were five dietary treatments: control, Acid 1 (acetic, propionic, phosphoric and citric acid; 1.1% inclusion), Acid 2 (Acid 1 + 1.0% lactic acid), herbal extracts (0.75% inclusion; containing cinnamon, thyme and oregano extract), and antibiotic (110 ppm lincomycin). As compared to the control, pigs on antibiotic and Acid 2 showed higher (P < 0.05) ADG only during week 2 post-weaning, whereas pigs on herbal extract showed lower (P < 0.05) ADG only during week 3 post-weaning. Fecal coliform counts were lower (P < 0.08) in pigs on Acid 1 and 2 on day 4 post-weaning and in pigs on antibiotic and herbal extract on day 14 post-weaning. Fecal lactobacilli counts were lower (P < 0.05) in pigs on antibiotic on day 14 post-weaning. Based on PCR-DGGE, treatment influenced the composition of gut microbiota. The pH of the colon was lower (P < 0.05) in pigs on acid treatments and serum IgG was lower (P < 0.05) in pigs on antibiotic. Dietary treatment did not affect (P > 0.10) intestinal morphology. These results show that the inclusion of antibiotic in the diet reduced the proliferation of both potentially harmful coliform bacteria and potentially beneficial lactobacilli in the pig’s gut, while herbal extract and organic acids appeared to reduce the proliferation of coliform bacteria. Blends of organic acids can serve as an alternative to in-feed antibiotics during the first few weeks post-weaning for pigs.

Abstract The aim of this trial was to determine the optimal supplementation mealworm on growth performance, apparent total tract retention of nutrients, hematological traits, immune response, and intestinal morphology in weaned pigs. A total of 180 weaned pigs (Landrace×Yorkshire×Duroc; 6.27 ± 0.15 kg) were randomly allotted to 3 treatments and 6 replicates on the basis of initial body weight and sex. The dietary treatments included a corn-based diet supplemented with 0, 2.5, or 5 % mealworm in 2 phases (0–14 and 15–28 d). The gain to feed ratio (G:F) was higher in pigs fed 2.5% mealworm compared with 2.5% during the first phase. Overall ADG was improved in pigs fed 2.5% mealworm compared with pigs fed 5% mealworm. No improvement in overall ADFI and G:F were observed. No digestibility responses were observed by adding mealworm to the diet, but the digestibility of DM and GE were tended to be higher in pigs fed 2.5% mealworm compared with control in phase 1. The number of monocytes tended to be increased in pigs fed 5% mealworm. The concentration of plasma IgG was higher in pigs fed mealworm, however, the plasma IL-6 was tended to be decreased when mealworm was added to the diet (P = 0.052). There was no change in intestinal morphology with increasing dietary levels of mealworm. The results showed that the dietary supplementation of 2.5% mealworm had beneficial effects on growth performance and immune system, however, no effects were detected on growth performance when 5% mealworm was added to the diet.

Marine algae polysaccharides have been shown to regulate various biological activities, such as immune modulation, antioxidant, antidiabetic, and hypolipidemic. However, litter is known about the interaction of these polysaccharides with the gut microbiota. This study aimed to evaluate the effects of marine algae Enteromorpha (Ulva) prolifera polysaccharide (EP) supplementation on growth performance, immune response, and caecal microbiota of broiler chickens. A total of 200 1-day-old Ross-308 broiler chickens were randomly divided into two treatment groups with ten replications of ten chickens in each replication. The dietary treatments consisted of the control group (fed basal diet), and EP group (received diet supplemented with 400 mg EP/kg diet). Results showed that chickens fed EP exhibited significantly higher (P &lt; 0.05) body weight and average daily gain than the chicken-fed basal diet. In addition, significantly longer villus height, shorter crypt depth, and higher villus height to crypt depth ratio were observed in the jejunal and ileal tissues of chickens fed EP. EP supplementation upregulated the mRNA expression of NF-κB, TLR4, MyD88, IL-2, IFN-α, and IL-1β in the ileal and jejunal tissues (P &lt; 0.05). Besides, we observed significantly higher (P &lt; 0.05) short-chain volatile fatty acids (SCFAs) levels in the caecal contents of the EP group than in the control group. Furthermore, 16S-rRNA analysis revealed that EP supplementation altered gut microbiota and caused an abundance shift at the phylum and genus level in broiler chicken. Interestingly, we observed an association between microbiota and SCFAs production. Overall, this study demonstrated that supplementation of diet with EP promotes growth performance, improves intestinal immune response and integrity, and modulates the caecal microbiota of broiler chickens. This study highlighted the application of marine algae polysaccharides as an antibiotic alternative for chickens. Furthermore, it provides insight to develop marine algae polysaccharide-based functional food and therapeutic agent.
