The present study investigated the effects of microbial additives producing antimicrobial and digestive-enzyme activities on the growth performance, blood metabolites, and fecal microflora of weaning pigs from 21 to 42 d of age. A total of 144 weaning pigs (1:1 ratio of gilt and boar; 21 d of age; 7.40 ± 0.53 kg of average body weight) were randomly distributed into four supplementary levels of microbial additive (0 vs. 0.5 vs. 1.0 vs. 1.5% of fresh weight) with three pens of replication, consisting of 12 weaning pigs per pen. All weaning pigs were maintained with the same basal diet for 21 d. Blood and feces were subsampled at day 21. Feed efficiency tended to increase linearly (p = 0.069) with an increasing supplementation level. Insulin, insulin-like growth factor 1, and blood glucose presented a quadratic effect (p < 0.05) with an increasing supplementation level, and these blood metabolites were highest at the 1% supplementation level. Immunoglobulin G in blood increased linearly by (p < 0.05) increasing the supplementation level. Salmonella and Escherichia coli in feces were decreased linearly by (p < 0.05) increasing the supplementation level. In conclusion, supplementation of microbial additive at 1.0% improved the feed efficiency, blood metabolites, and fecal microflora of weaning pigs.

Present study was undertaken to evaluate the effect of zinc supplementation on growth performance and nutrient utilization in kids. Twenty four goat kids (4-6 month age) were randomly divided into 4 groups (T1, T2, T3 and T4) having 6 kids each. Kids in the group T1 were fed basal diet which contained 29.02 mg Zn/kg DM from ingredients of ration without any additional Zn supplementation. Kids in the T2, T3 and T4 groups were fed the same basal diet with additive 20, 50 and 100 ppm Zn (as ZnSO4) in their diets, respectively. The study was conducted for 90 days. Digestion trial of 7 days was conducted towards the end of experiment to assess the digestibility of the nutrients. Results indicated significantly higher average body weight gain, crude protein (CP) digestibility and better feed efficiency in kids fed diet supplemented with 50.0 mg Zn/kg DM. From the results it was concluded that the Zn supplementation @ 50.0 mg/kg DM in basal diet significantly improved body weight (BW) gain, CP digestibility and feed efficiency ratio (FER) of kids.

Abstract The objective of this study was to evaluate the effects of dietary supplementation of coated omega-3 fatty acid (n-3 CFA) by corn cob power silica on performance of weaning pigs. A total of 200 weaned pigs [(Landrace x Yorkshire) x Duroc, average initial body weight at 6.97 ± 1.22 kg] were randomly assigned to four experimental treatments in a 6-week experiment in 3 phases as follows: CON, basal diet; 2) 0.3CFA, CON + phase 1(0.3% n-3CFA), phase 2(0.2% n-3CFA), phase 3(0.1% n-3CFA); 3) 0.6CFA, CON + phase 1(0.6% n-3CFA), phase 2(0.4% n-3CFA), phase 3(0.2% n-3CFA); 4) 0.9CFA, CON + phase 1(0.9% n-3CFA), phase 2(0.6% n-3CFA), phase 3 (0.3% n-3CFA). Each treatment had 10 replicates with 5 pigs (three gilts and two barrows) per replicate. The data were analyzed using the GLM procedure of SAS as a randomized complete block design. Pen served as the experimental unit. Linear, quadratic and cubic polynomial contrasts were used to examine effect of dietary treatment with coated n-3FA in the basal diet. Variability in the data was expressed as the standard error of means and P&lt; 0.05 was considered to statistically significant. Increasing the level of n-3CFA in the diet linearly increased ADG and G/F of pigs (Table 1). Increasing the level of n-3CFA showed a linear increment in the digestibility of DM (83.59, 84.38, 85.13, 85.89 %) whereas nitrogen digestibility (81.79, 82.38, 82.96, 83.64 %) showed a trend (linear effect, p=0.0594) at the end of experiment. The fecal lactobacillus count was increased (7.22, 7.27, 7.33, 7.35 log10cfu/g) with the increase in the supplemental level of n-3CFA (linear effect; p&lt; 0.05). However, there were no differences in the concentration of serum haptoglobin, or fecal E. coli, Clostridium and Salmonella counts despite the increase in n-3CFA levels in the diet. Supplementation of the diet with coated n-3 fatty acids positively affected growth performance and digestibility of dry matter and nitrogen, and enhanced the count of lactobacillus in weaning pigs.

AbstractThe present study was conducted to investigate effects of Bacillus subtilis on growth performance, serum parameters, digestive enzymes, intestinal morphology, and colonic microbiota in piglets. A total of 72 piglets were weighed and randomly allotted into three treatments (four replication pens per treatment with six piglets/pen) for a 28-day experiment. The dietary treatments were as follows: basal diet (control group, CTR), basal diet supplementation with antibiotic (antibiotic group, ABT), and basal diet supplementation with 0.1% Bacillus subtilis (probiotic group, PBT). The average daily gain of body weight increased in both the ABT and PBT groups, and dietary antibiotics decreased the feed:gain ratio (F:G), as compared to the CTR group (P < 0.05). Both ABT and PBT piglets had increased serum triglycerides and lipase, amylase, maltase activities and villus height:crypt depth ratio (V/C) in ileum (P < 0.05). The PBT group also showed an increase in serum glucose and villus height in the ileum (P < 0.05). Dietary antibiotics increased Lactobacillus johnsonii, as compared to the CTR group, but decreased bacterial diversity and increased Escherichia coli, as compared to the PBT group (P < 0.05). Piglets dietary with B. subtilis modulated the microbiota by increasing the abundance of Firmicutes (L. johnsonii, L. reuteri) and decreasing the abundance of E. coli, as compared to the control group (P < 0.05). These results indicate that dietary of B. subtilis improves growth performance and intestinal health and can be a promising alternative to antibiotics in piglets diet.

AbstractPasteurella multocida causes fowl cholera, a highly contagious poultry disease of global concern, causing significant ecological and economic challenges to the poultry industry each year. This study evaluated the effects of novel multi-strain probiotics consisting of Lactobacillus plantarum, L. fermentum, Pediococcus acidilactici, Enterococcus faecium and Saccharomyces cerevisiae on growth performance, intestinal microbiota, haemato-biochemical parameters and anti-inflammatory properties on broilers experimentally challenged with P. multocida. A total of 120 birds were fed with a basal diet supplemented with probiotics (108 CFU/kg) and then orally challenged with 108 CFU/mL of P. multocida. Probiotics supplementation significantly (P < 0.05) improved growth performance and feed efficiency as well as reducing (P < 0.05) the population of intestinal P. multocida, enterobacteria, and mortality. Haemato-biochemical parameters including total cholesterol, white blood cells (WBC), proteins, glucose, packed cell volume (PCV) and lymphocytes improved (P < 0.05) among probiotic fed birds when compared with the controls. Transcriptional profiles of anti-inflammatory genes including hypoxia inducible factor 1 alpha (HIF1A), tumor necrosis factor- (TNF) stimulated gene-6 (TSG-6) and prostaglandin E receptor 2 (PTGER2) in the intestinal mucosa were upregulated (P < 0.05) in probiotics fed birds. The dietary inclusion of the novel multi-strain probiotics improves growth performance, feed efficiency and intestinal health while attenuating inflammatory reaction, clinical signs and mortality associated with P. multocida infection in broilers.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.

Abstract The objective of this experiment was to investigate dietary supplementation of oligosaccharide-based polymer on growth performance, diarrhea, and fecal β-hemolytic coliforms of weaned pigs experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Forty-eight pigs (7.23 ± 1.11 kg BW) were individually housed in disease containment rooms and randomly allotted to one of four treatments with 12 replicate pigs per treatment. The four dietary treatments were a nursery basal diet (control), and 3 additional diets supplemented with 50 mg/kg Mecadox (AGP), 10 or 20 mg/kg of oligosaccharide-based polymer. The experiment lasted 18 d [7 d before and 11 d after the first inoculation (d 0)]. The doses of F18 E. coli inoculum were 1010 cfu/3 mL oral dose daily for 3 days. Growth performance was measured on d -7 to 0 before inoculation, and d 0 to 5 and 5 to 11 post-inoculation (PI). Diarrhea score (DS; 1, normal, to 5, watery diarrhea) was daily recorded for each pig. Fecal samples were collected on d 2, 5, 8, and 11 PI to test the percentage of β-hemolytic coliforms in total coliforms. All data were analyzed by ANOVA using the PROC MIXED of SAS with pig as the experimental unit. Inclusion of oligosaccharide-based polymer linearly increased (P &lt; 0.05) ADFI on d 0 to 5 PI, and feed efficiency on d 0 to 5 PI and d 5 to 11 PI (P = 0.07), compared with the control. Supplementation of AGP or oligosaccharide-based polymer reduced (P &lt; 0.01) frequency of diarrhea of pigs from d 0 to 11 PI. No differences were observed in overall growth performance and percentage of fecal β-hemolytic coliforms on d 8 PI among pigs in AGP and oligosaccharide-based polymer treatments. In conclusion, supplementation of oligosaccharide-based polymer enhanced feed efficiency and reduced diarrhea of weaned pigs infected with a pathogenic E. coli.
