This study was conducted to evaluate the effects of dietary supplementation with probiotics on growth performance, faecal microbiota, and serum profiles in weaned piglets. Large White × Landrace piglets (n = 144) weaned at 35–37 days of age were selected and divided into four groups, and the piglets from each group were assigned randomly to six pens (replicates) with six animals each. Each group was fed one of four diets for 5 weeks: a basal diet without antibiotics and probiotics (control), or the basal diet supplemented with Lactobacillus plantarum GF103, Bacillus subtilis B27, or a mixture of L. plantarum GF103 and B. subtilis B27. During the first 2 weeks of the supplementation, the piglets supplemented with probiotics had lower (P < 0.05) average daily feed intake than control piglets. The feed conversion ratio was improved (P < 0.05) in probiotic-supplemented groups compared with that of control. The population of E. coli in faeces of the piglets supplemented with L. plantarum GF103 was lower (P < 0.05) than that of control piglets. On day 14, dietary supplementation of the combination of L. plantarum GF103 and B. subtilis B27 increased (P < 0.05) the serum concentrations of total protein, globulin, and creatinine, but decreased (P < 0.05) the ratio of serum albumin to serum globulin, compared with the basal diet. On day 14, dietary supplementation with probiotics increased (P < 0.05) the serum IgM concentration compared with the basal diet. Supplementation of B. subtilis B27 or the combination of L. plantarum GF103 and B. subtilis B27 increased (P < 0.05) the serum IgA concentration at the end of the trial. These results suggest that dietary probiotics improved growth performance and enhanced immune responses at the early stage of the post-weaning period in piglets.

Abstract The objective of this study was to investigate the effects of dietary botanical supplementation on growth performance and frequency of diarrhea of weaned piglets experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Sixty weaned piglets (around 21 days old; 7.15 ± 0.97 kg) were individually housed and randomly allotted to one of five dietary treatments (n = 12): negative control (NC), positive control (PC), high dose of botanicals blend 1 (BB1, 100 ppm), low dose of botanicals blend 2 (BB2, 50 ppm), and high dose of botanicals blend 2 (BB2, 100 ppm). The experiment lasted 28 days: from day -7 to +21 relative to E. coli inoculation. All piglets except the pigs in the NC group were orally inoculated with F18 E. coli (1010 cfu per dose, 3 doses) for 3 consecutive days. Growth performance was recorded throughout the experiment and diarrhea scores were recorded daily. Data were analyzed by ANOVA using PROC MIXED of SAS with a randomized complete block design. E. coli challenge reduced (P &lt; 0.05) pig body weight and growth rate throughout the experiment. Pigs supplemented with high dose BB1 or BB2 tended (P &lt; 0.10) to have greater body weight (19.52 and 19.10 vs. 18.00 kg) on d 21 PI and greater average daily gain from d 0 to 21 PI (554 and 557 vs. 515 g/d) than PC. No differences were observed in pig performance between high dose BB1 or BB2 in comparison with NC. Supplementation of high dose BB1 or BB2 also reduced (P &lt; 0.05) frequency and severity of diarrhea of challenged pigs during the entire experimental period. In conclusion, dietary supplementation of botanicals reduced diarrhea and tended to improve growth performance of weaned pigs infected with E. coli.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Abstract Background: The effects of dietary supplementation with guava leaf extracts (GE) on growth performance, diarrhea and intestinal barrier function, as well as associated with its modulation of serum and fecal metabolic changes in weaned piglets challenged by enterotoxigenic Escherichia coli (ETEC) were investigated.Method: Fifty weaned piglets (Duroc × Yorkshire × Landrace) from 5 pens (2 piglets per pen) were randomly divided into five groups: blank control group (BC), negative control group (NC), or those supplemented with 50 mg kg-1 (S50), 100 mg kg-1 (S100), or 200 (S200) mg kg-1 diet GE, respectively. On day 4, all piglets (except for BC) were orally challenged with about 1.0 × 109 colony-forming units (CFU) enterotoxigenic ETEC. After 28-day trial, growth performance, diarrhea incidence, intestinal barrier function and metabolomics of serum and fecal were investigated.Results: We demonstrated that dietary supplementation with GE (50-200 mg kg-1) reduced diarrhea incidence of piglets and increased expression of intestinal tight junction proteins (ZO-1, Occludin, Claudin-1) (P < 0.05) and sodium hydrogen exchanger 3 (NHE3) (P < 0.05). Moreover, dietary supplementation with GE (50-200 mg kg-1) upregulated level of tetrahydrofolic acid (THF) and reversed higher level of nicotinamide-adenine dinucleotide phosphate (NADP) caused by ETEC in serum compared with NC group (P < 0.05), and enhanced antioxidant ability of piglets. In addition, dietary addition with GE (100 mg kg-1) reversed the lower level of L-pipecolic acid caused by ETEC in feces compared with NC group (P < 0.05), and decreased oxidative stress response of piglets. Further, there were no differences (P > 0.05) in the final weight, average daily feed intake (ADFI) and F/G among dietary groups during the overall period, and piglets in S50 group has the higher average daily gain (ADG). Conclusion: Dietary supplementation with 50-200 mg kg-1 GE reduced diarrhea incidence of weaned piglets challenged by ETEC and exhibited positive effect on improving intestinal barrier function. Meanwhile, dietary addition with GE organized and redistributed energy resources through similar or dissimilar metabolic pathways, and finally enhanced antioxidant ability of piglets challenged by ETEC.

Dietary Treatments

A total of 150 crossbred pigs [(Duroc × Yorkshire) × Landrace; body weight (BW) = 5.74 ± 1.15 kg; weaned at day 21 after birth] were assigned to one of five dietary treatments (six pens per treatment and five pigs per pen) by BW and sex (two barrows and three gilts) for a 6 wk experiment. The pen was considered the experimental unit in the statistical model. Treatments were corn–soybean meal diets supplemented with 0.0033% tiamulin as well as 0%, 0.05%, 0.10%, or 0.20% fermented garlic (FG). The average daily gain, average daily feed intake (ADFI), and feed conversion ratio were linearly (p < 0.05) increased by FG inclusion during days 21–42 and days 0–42. Dietary supplementation of FG linearly increased (p < 0.05) the coefficient of apparent total tract digestibility of dry matter, nitrogen, and gross energy as well as blood immunoglobulin G concentration during week 6. The fecal ammonia (NH3), total mercaptan emissions, and Escherichia coli counts were linearly (p < 0.05) reduced by FG in the diet. Dietary supplementation of FG increased (p < 0.05) ADFI during days 21–42 and days 0–42 and reduced (p < 0.05) fecal NH3 emissions compared with pigs fed tiamulin. In conclusion, the results indicate that FG can enhance growth performance and digestibility, and reduce fecal E. coli counts as well as fecal gas emissions in weanling pigs.
