Abstract Essential oils are potential antimicrobial alternatives and their applications in animal feeds are limited due to their fast absorption in upper gastrointestinal tract. This study investigated the effects of encapsulated cinnamaldehyde (CIN) at 50 mg/kg or 100 mg/kg on the growth performance, organ weights, meat quality, intestinal morphology, jejunal gene expression, nutrient digestibility, and ileal and cecal microbiota. A total of 320 male day-old broiler Cobb-500 chicks were randomly allocated to 4 treatments with 8 pens per treatment (10 birds per pen): 1) basal diet (negative control, NC); 2) basal diet supplemented with 30 mg/kg avilamycin premix (positive control, PC); 3) basal diet with 50 mg/kg encapsulated CIN (EOL); 4) basal diet with 100 mg/kg encapsulated CIN (EOH). Despite birds fed EOH tended to increase (P = 0.05) meat pH at 24 h, all pH values were normal. Similar to PC group, meat from birds fed EOL and EOH showed a reduced (P < 0.05) Warner-Bratzler force shear (WBFS) compared to the NC group. The highest villus to crypt ratios (VH/CD; P < 0.05) were observed in broiler fed either EOL or EOH, with an average being 14.67% and 15.13% in the duodenum and 15.13% and 13.58% in the jejunum, respectively. For jejunal gene expressions, only six out of the 11 studied genes showed statistically differences among the dietary treatments. Gene expressions of cationic amino acid transporter 1 (CAT-1) and neutral amino acid transporter 1 (B 0AT-1) were upregulated in EOH-fed birds compared to PC and NC-fed birds (P < 0.05), respectively; while expression of proliferating cell nuclear antigen (PCNA) were downregulated in EOL-fed birds when compared to NC birds (P < 0.05). Nonetheless, the expressions of cadherin 1 (CDH-1), zonula occludens 1 (ZO-1), and maltase-glucoamylase (MG) were all upregulated (P < 0.05) in EOH-fed birds compared to PC-fed birds. The apparent ileal digestibility (AID) of dry matter, crude protein, crude fat and of all 18 tested amino acids increased in EOL-fed birds (P < 0.01). Additionally, relative abundances (%) of ileal Proteobacteria decreased, while ileal and cecal Lactobacillus increased in EOH-fed birds (P < 0.05). In conclusion, dietary encapsulated CIN improved meat quality and gut health by reducing meat WBFS, increasing VH/CD in intestines, jejunal gene expressions, AID of nutrients and beneficially ileal and cecal microbiota composition.

Abstract Background: Essential oils are potential antimicrobial alternatives and their applications in animal feeds are limited due to their fast absorption in upper gastrointestinal tract. This study investigated the effects of encapsulated cinnamaldehyde (CIN) at 50 ppm or 100 ppm on the growth performance, organ weights, meat quality, intestinal morphology, jejunal gene expression, nutrient digestibility, and ileal and cecal microbiota. A total of 320 male day-old broiler Cobb-500 chicks were randomly allocated to 4 treatments with 8 pens per treatment (10 birds per pen): 1) basal diet (negative control, NC); 2) basal diet supplemented with 30 ppm avilamycin premix (positive control, PC); 3) basal diet with 50 ppm encapsulated CIN (EOL); 4) basal diet with 100 ppm encapsulated CIN (EOH).

Abstract This study aimed to evaluate the effects of supplementing broiler diets with a dietary protease on growth performance, digestive function, intestinal morphology, and meat quality as compared with feeding diets with or without an antibiotic growth promoter (AGP). A total of 240 1-day-old male chicks (Cobb 500, 48.3 ± 3.3 g) were distributed to three treatments with eight replicates (10 birds per replicate). Three treatments were: 1) corn–soybean meal basal diets (CTRL), 2) basal diets with 0.003% avilamycin (AB), and 3) basal diets with 0.0125% protease (PRT). The diets were provided as mash form, and birds were fed ad libitum during the whole experimental period. On day 45, birds were euthanized, and tissue and digesta samples were collected. On day 46, the remaining birds were processed in a commercial slaughterhouse, and breast muscle samples were collected. Despite a trend for a decreased feed conversion ratio (FCR) in the AB group during the whole phase (P = 0.071), no significant differences in growth performance parameters and relative weights of organs were observed (P &gt; 0.05) among the groups. The AB and PRT groups showed significantly greater apparent ileal digestibility of amino acids (AA) compared with the CTRL group (P &lt; 0.05). The PRT group significantly improved the morphology of duodenum and jejunum (P &lt; 0.05). No differences were detected for meat quality, white striping, and woody breast among the groups (P &gt; 0.05). For the gene expressions, the AB group showed a greater level of B0-system neutral amino acid co-transporter 1 and excitatory amino acid transporter 1 mRNA abundance compared with PRT group, while a significantly lesser level of cationic amino acid transporter 1 mRNA abundance was observed in the AB group compared with CTRL group (P &lt; 0.05). The PRT group had a lesser level of peptide transporter 1 mRNA abundance in the jejunum than the CTRL group (P &lt; 0.05). The highest mRNA abundances of zonula occludens-1 and cadherin 1 were observed in the CTRL group (P &lt; 0.05). In conclusion, supplementation of avilamycin tended to reduce FCR and significantly improved AA utilization, and supplementation of dietary protease significantly enhanced intestinal morphology and AA utilization in broilers. In that respect, exogenous protease use appears to be an interesting tool to be considered in AGP reduction strategies.

Abstract This study investigated the effects of encapsulated citral (CIT) and cinnamaldehyde (CIN) on growth performance, intestinal morphology and meat quality in broilers. A total of 320 0-day-age male broilers (Cobb 500) were allocated 32 pens with 8 pens per treatment. The treatments included: 1) Corn-wheat-SBM basal diet (negative control); 2) basal diet with 30 ppm avilamycin premix (positive control); 3) basal diet with 50 ppm encapsulated CIT and CIN (CCL); 4) basal diet with 100 ppm encapsulated CIT and CIN (CCH). There were no significant differences between treatments in growth performance (P &gt; 0.05) at each feeding stage. Additionally, birds had similar relative organ weights of heart, liver, spleen and bursa (P &gt; 0.05). The higher ratios of villus height to crypt depth (VCR; P ≤ 0.05) were detected in broilers fed either CCL or CCH, with an average being 14.67 and 15.13 in the duodenum, and 15.13 and 13.58 in the jejunum, respectively. Regarding meat quality, a higher pH value (pH = 6.21) in the breast was observed in 24-h post mortem chickens fed CCL (P ≤ 0.05). No significant differences of pH were detected in the breast in 96-h post mortem birds. The breast color (redness, yellowness, and lightness) in either 24-h or 96-h post mortem chickens was not significantly different among treatments (P &gt; 0.05). No change in purge loss (%) was observed in the breast after 48 h. The severity of white striping (WS) or woody meat (WB) was higher in the positive control (WS = 0.58; WB = 0.15) than in other treatments (P ≤ 0.05). In conclusion, dietary treatment with encapsulated CIT and CIN improved gut morphology and meat quality of broilers by increasing VCR in the small intestine and reducing the severity of WS/WB in the breast, respectively, without affecting growth performance.

Aim: The experiment was conducted to evaluate the effect of swine-origin probiotic Pediococcus acidilactici FT28 on growth, nutrient utilization, health status, meat quality and intestinal morphology in growing female pigs. Materials and Methods: Pigs (n=27) were distributed into three groups (3 replicates of 3 each) and supplemented with basal diet either without probiotics (C) or with a probiotic of dairy-based (Lactobacillus acidophilus NCDC-15; TLact) or swine based (P. acidilactici FT28; TPedic). The probiotics were fed as fermented feed at 200 g/pig/day. At the end of the trial, six pigs from each group were selected for metabolism trial and then sacrificed to determine meat quality and intestinal morphology. Results: Supplementation of both probiotics improved growth performance, whereas feed intake, digestibility of CP and N retention were better (p<0.05) in P. acidilactici FT28-fed group. However , the digestibility of dry matter (DM), organic matter (OM), ether extracts (EE), crude fibre and nitrogen free extract did not show any significant effect on probiotic supplementation. The serum A: G ratio, triglyceride, and cholesterol level were also improved (p<0.05) in TPedic group compared to other treatment groups. Both probiotic supplementations showed lower (p<0.05) serum glucose level with similar protein and albumin value, which indicated good utilization of feed as well as health status of growing pigs. Dressing percentage, vital organ weight, and EE of loin meat were higher (p<0.05) in probiotic-supplemented groups compared to control. However, P. acidilactici FT28-fed animals showed higher (p<0.05) CP and total ash percentage of meat without affecting pH, water holding capacity, and extract release volume of loin muscle. The villi height and crypt depth were better in both supplemented groups compared to control. Conclusion: Results of the present study revealed that P. acidilactici FT28 could serve as better probiotic source in swine production for the better utilization of CP and N-retention in meat with improved health status and intestinal morphology.

Abstract Background This study was conducted to explore the protective potential of Fructooligosaccharides (FOS) against Enterotoxigenic Escherichia coli (ETEC)-induced inflammation and intestinal injury in weaned pigs. Methods Twenty-four weaned pigs were randomly assigned into three groups: (1) non-challenge (CON), (2) ETEC-challenge (ECON), and (3) ETEC challenge + 250 mg/kg FOS (EFOS). On day 19, non-challenged pigs were orally infused with sterilized culture while pigs in other groups were orally infused with ETEC (2.5 × 1010 colony-forming units). After 3 days, pigs were slaughtered for sample collection. Results We show that ETEC-challenged significantly reduced average daily gain (ADG); however, FOS improved the ADG (P < 0.05) and apparent digestibility of crude protein (CP), gross energy (GE), and ash in the ETEC-challenged pigs (P < 0.05). FOS reduced plasma concentrations of IL-1β and TNF-α, and elevated the concentrations of immunoglobulin A (IgA) and immunoglobulin M (IgM) (P < 0.05). Interestingly, FOS elevated villus height in duodenum, and elevated the ratio of villus height to crypt depth in the duodenum and ileum in the ETEC-challenged pigs (P < 0.05). Moreover, FOS increased lactase activity in the duodenum and ileum (P < 0.05). The activities of sucrase and alkaline phosphatase (AKP) were higher in EFOS group than in the ECON group (P < 0.05). Importantly, FOS up-regulated the expressions of critical genes in intestinal epithelium function such as zonula occludens-1 (ZO-1), L-type amino acid transporter-1 (LAT1), and cationic amino acid transporter-1 (CAT1) in the duodenum and the expressions of ZO-1 and glucose transporter-2 (GLUT2) in the jejunum (P < 0.05). FOS also up-regulated the expressions of occludin, fatty acid transporter-4 (FATP4), sodium glucose transport protein 1 (SGLT1), and GLUT2 in the ileum (P < 0.05). FOS significantly increased the concentrations of acetic acid, propionic acid and butyric acid in the cecal digesta. Additionally, FOS reduced the populations of Escherichia coli, but elevated the populations of Bacillus and Bifidobacterium in the caecal digesta (P < 0.05). Conclusions These results suggested that FOS can improve the growth performance and intestinal health in weaned pigs upon ETEC challenge, which was associated with suppressed inflammatory responses and improved intestinal epithelium functions and microbiota.

Didancao (Elephantopus scaber L.) has been used as a traditional herbal medicine and has exhibited a beneficial role in animal health. This study aimed to investigate the effects of dietary supplementation with E. scaber on growth performance, meat quality, intestinal morphology, and microbiota composition in ducks. A total of 480 Jiaji ducks (42 days old, male:female ratio = 1:1) were randomly assigned to one of four treatments. There were six replicates per treatment, with 20 ducks per replicate. The ducks in the control group (Con) were fed a basal diet; the three experimental groups were fed a basal diet supplementation with 30 (T1), 80 (T2), and 130 mg/kg (T3) of E. scaber. After a 48-day period of supplementation, growth performance, meat quality, intestinal morphology, and microbiota composition were evaluated. The results showed that no differences were observed in the final body weight, average daily feed intake, and average daily gain among the four groups. Compared with that in the Con group, the feed conversion in the T1 and T2 groups was increased significantly; the T2 group was shown to decrease the concentration of alanine aminotransferase in serum; the T3 group was lower than the Con group in the concentration of aspartate aminotransferase and was higher than the Con group in the concentration of high-density lipoprotein-cholesterol. The highest concentration of creatinine was observed in the T1 group. The T2 group was higher than the Con group in the contents of Phe, Ala, Gly, Glu, Arg, Lys, Tyr, Leu, Ser, Thr, Asp, and total amino acids in the breast muscle. Moreover, the T2 group was higher than the Con group in the contents of meat C18:2n−6 and polyunsaturated fatty acid. The concentration of inosinic acid in the T1, T2, and T3 groups was significantly higher than that in the Con group. However, the Con group was higher than the T2 or T3 group in the Zn content. The T2 group was lower than the Con group in the jejunal crypt depth. The T3 group was higher than the Con group in the ileal villus height and the ratio of villus height to crypt depth. In addition, the T3 group had a trend to significantly increase the abundance of Fusobacteria. Compared with the Con group, the T1 and T2 groups displayed a higher abundance of Subdoligranulum. Collectively, dietary supplementation with 80 mg/kg of E. scaber improves meat quality and intestinal development in ducks.

This study is to evaluate the effects of mineral Detoxified nano-Sulfur Dispersion (DSD) on growth performance, fecal score, fecal microbial, gas emissions, blood profile, nutrient digestibility and meat quality in finishing pigs. A total of 160 pigs with an initial body weight of 54.90 ± 5.10 kg were randomly assigned to 2 treatments include basal diet and basal diet with 10ppm DSD. During 10 week trial there were no differences in body weight (BW), average daily gain (ADG), average daily feed intake (ADFI) and gain to feed ratio (G:F) between the control and DSD groups. Also, the fecal score, fecal microbiota, gas emission was not affected by DSD diet. Dietary inclusion of DSD tended to increase water holding capacity and decrease cooking loss and drip loss. At week 5, serum concentrations of glucose, calcium, total cholesterol, high-density level were increased, and triglyceride concentration was reduced in pigs fed with DSD than control diets. In summary, the inclusion of dietary DSD in the finishing pig diet has improved serum Ca, glucose concentrations and lipid profiles as well as it improves some meat quality traits.

The main objective of the investigation was to observe the growth performance, carcass yield, meat quality, and intestinal morphology of broiler chicks with respect to the dietary crude palm stearin (CPS). The study was conducted on 200 birds and dividing them into two experimental groups viz control and CPS treated group with 10 replications of 10 birds in each. Chicks under the control group were fed basal diet only, however in CPS treated group chicks were fed the basal diet supplemented with 3% CPS. Birds were reared for 42 days and data regarding different parameters of study was recorded. Data were analyzed by student T-test and differences were considered significant at P < 0.05.Results indicated CPS treated group pertaining to lower final body weight, daily weight gain, feed conversion ratio, feed intake, dressing percentage, fillets, thight+drumsticks, and wings percentages. CPS treated group possessed lower liver, spleen, gizzard, and abdominal fat weights. Breast meat holds lower values for shear force, drip loss in CPS treated group, while cooking loss found vice versa. Abdominal fat breast in the meat and thigh skin possessed higher a* (redness) and b* (yellowness) values in CPS treated chicks, while breast skin and thigh meat hold lower a* and b* values in CPS treated chicks compared to control. Intestinal villus height, villus area and crypts depth in duodenum found considerably higher in the CPS treated chicks. Jejunum in CPS treated group possessed higher crypt depth but villus height and villus area remained lower. In conclusion, CPS impairs overall growth performance, carcass yield and meat quality but supports the intestinal morphology.
