Oregano Essential Oil

Abstract Essential oils are plant-derived aromatic volatile oils, and they contain bioactive compounds that have been shown to improve poultry nutrition. In this study, we investigated the effects of oregano essential oil (OEO) on intestinal antioxidative capacity, immunity, and gut microbiota of young yellow-feathered chickens. A total of nine hundred and sixty 1-d-old female Qingyuan partridge chickens were randomly allocated to four treatment groups with six replicates of 40 birds each, and the feeding trial was lasted for 30 d. The controls were fed on a basal diet without in-feed antibiotics; the birds in the antibiotic group were fed the basal diet supplemented with 20 mg/kg virginiamycin; the remaining birds were fed the basal diet containing 150 or 300 mg/kg OEO, respectively. Dietary supplementation with 150 or 300 mg/kg OEO increased average daily feed intake (P = 0.057) and average daily gain (P < 0.05). The activities of glutathione peroxidase and total antioxidative capacity in plasma, jejuna, and ileal mucosa were increased by OEO supplementation (P < 0.05), with a trend of lower jejunal content of malonaldehyde (P = 0.062). Moreover, dietary OEO increased the content of secretory immunoglobulin A (P = 0.078) and the relative expression of Claudin 1, Mucin 2, and Avain beta-defensin 1 in ileum (P < 0.05). Sequencing data of 16S rRNA indicated that dietary OEO increased the relative abundance of Firmicutes phylum, and Clostridium and Lactobacillus genera, and decreasing that of Romboutsia. Functional analyses indicated that microbial amino sugar and nucleotide sugar metabolism, replication, and repair systems were higher in OEO groups than those of controls and antibiotic treatment. In conclusion, dietary supplementation with OEO enhanced growth performance, alleviated local oxidative stress in intestine, improved production of natural antibodies, and favorably modulated intestinal microbiota composition.

Oregano Essential Oil

This study investigated the effects of supplementing oregano essential oil (OEO) to a reduced-protein diet on growth performance, nutrient digestibility, intestinal bacteria, intestinal morphology, and antioxidative capacity of growing-finishing pigs. Forty-eight barrows were randomly allotted to four treatments including normal-protein diet (NPD), reduced-protein, amino acid-supplemented diet (RPD), the same RPD supplemented with chlortetracycline (RPA), and RPD supplemented with OEO (RPO). The data showed that dietary OEO supplementation increased the average daily gain of pigs compared with NPD and RPD. The gain:feed in RPO- and NPD-fed pigs was higher than those in RPD- and RPA-fed pigs. Increased average daily feed intake and 10th-rib backfat thickness were detected in RPA-fed pigs. Pigs fed the RPO had higher apparent total tract digestibility (ATTD) of crude protein than those fed the other diets. The RPD and RPA treatments showed reduced counts of Lactobacillus spp. in ileal digesta of pigs. The RPA and RPO treatments also showed lower Escherichia coli counts in ileal digesta than the NPD and RPD treatments. Dietary OEO supplementation increased villous height of the jejunum and the ileal and plasma total antioxidative capacity of pigs. In conclusion, dietary OEO supplementation could improve the growth performance and nutrient digestibility of pigs by modulating intestinal bacteria, intestinal morphology, and antioxidative capacity.

Randomized Design

Abstract This study evaluated the functional effects of two chemotypes of oregano essential oil (OEO): Lippia Origanoides (LO) and a comercial product Synergy Essence (SE). Broilers were randomly assigned to one of eight dietary treatments: 1) Basal diet (BD); 2) BD+ antibiotic growth promoters (AGP) (bacitracin 50g/ton); 3) BD+LO125 (125g/ton); 4) BD+LO250 (250g/ton); 5) BD+LO500 (500g/ton); 6) BD+SE125 (125g/ton); 7) BD+SE250 (250g/ton); 8) BD+SE500 (500g/ton). At the time of slaughter (42 d), five birds per treatment were slaughtered. A portion of the breast was minced and stored at -4 ºC for 3, 6, and 9 days. Lipid peroxidation was determined by measuring of malondialdehyde (MDA), data were analyzed as a completely randomized design with a factorial arrangement of treatments (8x4). Broilers fed SE250 had greater average daily gain (ADG) compared to broilers fed BD (P<0.05). Broilers fed LO500 had greater (P<0.05) organic matter digestibility than the ones fed BD. As days of storage increased, MDA concentration increased (P<0.05). Broilers fed SE500 had lower (P<0.05) MDA concentration than those fed BD and AGP. These data indicate that birds fed OEO grow faster than those fed a BD, similar to birds fed AGP. Some of these responses are possibly explained by increased digestibility and energy utilization. In addition, providing OEO from SE at 500g/ton resulted in lower lipid peroxidation in ground breast meat throughout the tested storage time.

AbstractThe objective of this experimental study was to investigate the effects of essential oils of oregano, laurel and their combination on growth performance, intestinal microbiota and intestinal morphology as replacers of antibiotic growth promoters, as well as on the antioxidant capacity and mineral content of breast and thigh meat. A total of 256 day-old broiler chickens were randomized into 4 groups with 4 replicates. Control group received a basal corn-soybean diet, whereas the other experimental groups received the basal diet plus 25 mg/kg oregano essential oil, 2.5 mg/kg laurel essential oil or their combination, respectively. Chickens had free access to water and feed. Body weight gain and feed to gain ratio was calculated for the total fattening period and mortality was daily recorded. Intestinal microbiota was enumerated by conventional techniques with selective agar media at the end of the trial at both ileum and caecum. Also, evaluation of intestinal morphology was carried out in small intestine and caecum. At the end of the trial, birds were slaughtered, their carcasses were processed and samples of breast and thigh meat were analyzed for moisture, fat and protein content. Total phenolic content was determined in feeds and breast and thigh meat in order to assess its antioxidant capacity. Mineral content of breast and thigh meat was evaluated by ICP-MS. The results of the trial showed that the group that received oregano or the mixture of oregano and laurel presented better BW and FCR and mortality compared to control group. Bacterial counts for the Lactobacilli and Bifidobacteria were higher in the experimental groups compared to the control group at both ileum and caecum, and total coliforms were lower in caecum in the experimental groups compared to control. Higher values for villus height were found for the oregano supplemented groups compared to control or laurel ones. Oregano supplemented groups showed higher antioxidant capacity of breast and thigh meat compared to control and laurel groups, however no changes in mineral content were noted among the different groups. In conclusion, oregano essential oil alone or as a mixture with laurel essential oil can be used to improve growth performance and gut health in broiler chickens.

This experiment aimed to investigate effects of the different dietary levels of vitamin E (VE) on the growth performance, immunity and antioxidant capacity of goslings. A total of 240 1-day-old, male Jiangnan white goslings were selected and randomly divided into 6 groups. Each treatment included five replicates. The basal diet was supplemented with 6 concentrations of VE (0, 12, 24, 36, 48 and 60 mg DL-α-tocopherol acetate/kg). The results were as follows: (1) The α-tocopherol content in the serum and liver of goslings increased linearly as supplemental VE increased in diet (p < 0.05). (2) The body weight (BW) and average daily gain (ADG) increased quadratically with increasing dietary VE supplementation (p < 0.05). Dietary VE supplementation could significantly reduce the feed/gain ratio (F/G) (p < 0.05). (3) Dietary supplementation with VE could significantly improve the contents of immunoglobulin A (IgA) and immunoglobulin G (IgG) in the serum of the goslings (p < 0.05). The content of interferon-γ (IFN-γ) in the serum was significantly reduced with VE supplementation (p < 0.05). (4) Dietary supplementation with VE could significantly improve serum and liver catalase (CAT), superoxide dismutase (SOD) activities and liver total antioxidant capacity (T-AOC) (p < 0.05); Serum and liver MDA contents were significantly reduced with VE supplementation (p < 0.05). In summary, dietary supplementation with VE could improve growth performance, immunity and antioxidant capacity. Based on broken-line regression analysis, the dietary VE supplementation level for ADG was 12.51 mg/kg, but higher supplementation level should be considered to improve immunity and antioxidant capacity.

Abstract This study aimed to evaluate the effects of supplemental Bacillus licheniformis derived-protease in diets on growth performance, apparent total tract digestibility (ATTD), and fecal microbial shedding in post-weaned growing pigs. In total, 90 crossbred (Landrace × Yorkshire × Duroc) weaner pigs with an initial average BW of 6.61 ± 1.73 kg were randomly allotted into 2 treatments with 9 replicate pens of 5 pigs for a 4-phase feeding trial (0 to 1, 1 to 3, 3 to 6, and 6 to 11 weeks). The treatments were: CON, corn-soybean meal based basal diet; PROT, basal diet + 0.05% protease. The basal diet contained 16.32, 15.91, 15.49, and 14.91 MJ/kg digestibility energy respectively and 1.50, 1.40, 1.30, and 1.00% lysine respectively for phase 1, 2, 3, and 4. All data were statistically analyzed by Student’s t-test of SAS 9.4 (SAS Institute Inc., Cary, NC, USA). Variability in the data was expressed as mean ± standard deviation, differences with P &lt; 0.05 were considered to be statistically significant. During phase 3, average daily gain, and gain: feed ratio was increased (P &lt; 0.05) in pigs fed PROT diet compared with those fed CON diet. Pigs fed PROT diet had higher (P &lt; 0.05) ATTD of dry matter and crude protein than pigs fed CON diet. No differences were observed in fecal microflora counts between CON and PROT groups. Dietary supplementation of Bacillus licheniformis derived-protease increased growth performance at phase 3 and increased the digestibility) of dry matter and crude protein (insert mean values for both Con vs Treat) in growing pigs.

This study investigated the effects of dietary supplementation with fermented Mao-tai lees (FML) on growth performance, plasma metabolites, and intestinal microbiota and metabolites of weaned piglets. A total of 128 Duroc×Landrace×Yorkshire piglets (28-days old) were randomly assigned to one of four groups, feeding a basal diet (control group), a basal diet supplemented with 2, 4 or 6% FML, respectively, for 42days. The results showed that dietary 4% FML supplementation had higher (p&lt;0.05) average daily gain (ADG) and plasma triglyceride concentration during days 1–14 of the trial than the other FML supplemented groups. In addition, dietary 2 and 4% FML supplementation increased (p&lt;0.05) the ADG during days 15–28 of the trial and plasma total protein concentration on day 42 of the trial compared with the 6% FML supplement. The plasma concentrations of arginine, ethanolamine, histidine, isoleucine, lysine, methionine, proline, taurine, threonine, and tyrosine were increased (p&lt;0.05) in the 4% FML group compared with the other three groups on day 14 of the trial. Dietary supplementation with 2–6% FML decreased (p&lt;0.05) the plasma urea nitrogen concentration on day 14 of the trial and the abundance of Escherichia coli in the colon, and dietary 2 and 4% FML supplementation decreased (p&lt;0.05) the abundance of sulfate-reducing bacteria compared with the control group. In the intestinal contents, a higher concentration of FML (6%) supplementation decreased (p&lt;0.05) the colonic acetate concentration compared with the control and 2% FML groups, while 4% FML supplementation increased (p&lt;0.05) the colonic cadaverine concentration compared with the other three groups. In conclusion, dietary 4% FML supplementation might contribute to the increased amino acids metabolism without affecting the growth performance of weaned piglets. Moreover, dietary 2 and 4% FML supplementation were also beneficial to intestinal health via decreasing the abundances of specific pathogens and increasing the concentrations of microbial metabolites in the gut, which provides the theoretical basis and data support for the application of FML in pigs.
