Animals fed with a high amount of a wide range of antioxidants in their diet are significantly protected against oxidative stress. Powerful antioxidant substances such as vitamin E, vitamin C, and carotenoids are present naturally in red-hot pepper (RHP). This study hypothesized that using RHP may provide protection against oxidative stress and enhance animal physiological responses. Thus, this study aimed to investigate the effect of feeding New Zealand white rabbits with RHP-supplemented diets on their physiological and biochemical responses. New Zealand White rabbits (age = 6 weeks, n = 48) were split equally into three groups (n = 16 in each group). One group was fed a basal diet only (control group), with the other two groups fed a basal diet along with 1 and 2% RHP. Mass spectrometric analysis for the RHP methanolic extract showed some phenolic compounds, such as p-coumaric, sinapinic acids, vanillic, and luteolin, as well as catechin and its isomers. Hepatic antioxidant enzymes (SOD, GSH, GSH-Px, and CAT) were significantly elevated (p < 0.05) by feeding rabbits diets supplemented with 1 or 2% RHP. The addition of RHP significantly enhanced immune-responses; phagocytic activity, chemotaxis, TIg, IgG, IgM, and IgA increased when growing rabbits were fed RHP compared with the control group. In conclusion, dietary supplementation of 1 or 2% RHP may play a role as an enhancer of growth and immune response in growing rabbits.

Oxidative stress is induced by excessive oxidative radicals, which directly react with biomolecules, and damage lipids, proteins and DNA, leading to cell or organ injury. Supplementation of antioxidants to animals can be an effective way to modulate the antioxidant system. Chitosan oligosaccharides (COS) are the degraded products of chitosan or chitin, which has strong antioxidant, anti-inflammatory, and immune-enhancing competency. Therefore, the current study was conducted to evaluate the hypothesis that dietary supplementation with COS alleviates the damage caused by oxidative stress in Sprague Dawley rats challenged with hydrogen peroxide (H2O2). The rats were randomly divided into three groups: CON, control group, in which rats were fed a basal diet with normal drinking water; AS, H2O2 group, in which rats were fed the basal diet and 0.1% H2O2 in the drinking water; ASC, AS + COS group, in which rats were fed the basal diet with 200 mg/kg COS, and with 0.1% H2O2 in the drinking water. In vitro, COS exhibited better radical scavenging capacity of 1, 1-diphenyl-2-picrylhydrazyl (DPPH), superoxide anion (O2−), H2O2, and ferric ion reducing antioxidant power (FRAP) than butylated hydroxy anisole (BHA). In vivo, dietary supplementation with COS alleviated the H2O2-induced oxidative damage, evidenced by comparatively increasing activity of SOD, CAT, GSH-Px, GSH, and T-AOC, and comparatively decreasing level of MDA in serum, liver, spleen, and kidney. COS also comparatively alleviated the H2O2-induced inflammation. In conclusion, COS supplementation reduced lipid peroxidation and restored antioxidant capacity in Sprague Dawley rats, which were challenged with H2O2.

Abstract Background Chlorella vulgaris (CV) is a natural source of functional antioxidants capable of protecting against oxidative stress; its dietary supplementation in animals can serve as a way of improving animals’ performance and productive output; on this background, the microalgae was supplemented to growing New Zealand white rabbits and its effects on performances and oxidative stress status were evaluated. Method Thirty-five (35) 6-week-old New Zealand White rabbits (935.48 ± 5.92 g) were divided into five groups (n = 7 per group) in a completely randomized design experiment; rabbits in control groups were fed only commercial rabbits feed, while rabbits in treatment groups were supplemented with 200, 300, 400, and 500 mg Chlorella vulgaris biomass per kilogram of the body weight along with commercial rabbits feed daily. Feed intake and body weight changes were recorded daily and weekly; at the end of the study, blood was collected and subjected to chemical assays for evaluation of serum oxidative stress markers and antioxidant activities. Results Dietary supplementation of the microalgae significantly increased the rabbits’ growth weights (p < 0.01) without significant increase or reduction in feed intakes (p < 0.56), but significantly enhanced feed to gain ratio. The microalgae supplementation significantly protected the rabbits against oxidative stress damages through the reduction of malondialdehyde concentrations (p < 0.001) and increased total antioxidant capacity (p < 0.003). It also led to higher superoxide dismutase activity (p < 0.001), increased catalase activity (p < 0.003), and higher concentration of reduced glutathione (p < 0.001). Conclusion It was concluded from outcomes of both performance and biochemical analysis of the rabbits that daily supplementation of Chlorella vulgaris between 200 and 500 mg per kilogram of the body weight in prepubertal rabbits significantly improved performances in forms of higher weight gains and enhanced feed utilization; it also protected against oxidative stress damages hence it was recommended as dietary antioxidant supplement for growing prepubertal rabbits.

Recent evidences suggest that gut microbiota plays an important role in regulating physiological and metabolic activities of pregnant sows, and β-carotene has a potentially positive effect on reproduction, but the impact of β-carotene on gut microbiota in pregnant sows remains unknown. This study aimed to explore the effect and mechanisms of β-carotene on the reproductive performance of sows from the aspect of gut microbiota. A total of 48 hybrid pregnant sows (Landrace × Yorkshire) with similar parity were randomly allocated into three groups (n = 16) and fed with a basal diet or a diet containing 30 or 90 mg/kg of β-carotene from day 90 of gestation until parturition. Dietary supplementation of 30 or 90 mg/kg β-carotene increased the number of live birth to 11.82 ± 1.54 and 12.29 ± 2.09, respectively, while the control group was 11.00 ± 1.41 (P = 0.201). Moreover, β-carotene increased significantly the serum nitric oxide (NO) level and glutathione peroxidase (GSH-Px) activity (P &lt; 0.05). Characterization of fecal microbiota revealed that 90 mg/kg β-carotene increased the diversity of the gut flora (P &lt; 0.05). In particular, β-carotene decreased the relative abundance of Firmicutes including Lachnospiraceae AC2044 group, Lachnospiraceae NK4B4 group and Ruminococcaceae UCG-008, but enriched Proteobacteria including Bilophila and Sutterella, and Actinobacteria including Corynebacterium and Corynebacterium 1 which are related to NO synthesis. These data demonstrated that dietary supplementation of β-carotene may increase antioxidant enzyme activity and NO, an important vasodilator to promote the neonatal blood circulation, through regulating gut microbiota in sows.

Aging is a neurological disease that is afforded by incidence of oxidative stress. Chitosan has received global interests due to its wide medical uses. Quercetin (Q) is a bioflavonoid and widely distributed in vegetables and fruits. Resveratrol is considered as a potent antioxidant and is a component of a wide range of foods. The using of either chitosan nanopartciles (CH-NPs), querectin (Q), and resveratrol (RV) to reduce the oxidative stress and biochemical alterations on brain and testicular tissues induced by D-galactose (DG) (100 mg/Kg) were the aim of the present study. This study investigated the probable protective effects of CH-NPs in two doses (140,280 mg/Kg), Q (20 mg/Kg) and RV (20 mg/Kg), against DG induced aging and neurological alterations. Brain antioxidant capacity as malonaldehyde (MDA), catalase (CAT), and glutathione reductase (GRx), as well as histopathological damages of the brain and testicular tissues were measured. The DG treated group had significantly elevated the oxidative stress markers by 96% and 91.4% in brain and testicular tissues respectively and lower significantly the antioxidant enzyme activities of both brain and testicular tissues than those of the control group by 86.95%, 69.27%, 83.07%, and 69.43%. Groups of DG that treated with a combination of CH-NPs in two doses, Q and RV, the levels of oxidative stress marker declined significantly by 68.70%, 76.64% in brain tissues and by 74.07% and 76.61% in testicular tissues, and the enzymatic antioxidants increased significantly by 75.55%, 79.24%, 62.32%, and 61.97% as compared to the DG group. The present results indicate that CH-NPs, Q, and RV have protective effects against DG-induced brain and testis tissue damage at the biochemical and histopathological levels. Mechanisms of this protective effect of used compounds against neurological and testicular toxicity may be due to the enhanced brain and testis antioxidant capacities.

Sodium propanoate is in the list of approved feed preservatives. However, there is dearth of information on its biological effects on the C. gariepinus. The present study investigated the effect of sodium propanoate-preserved feed on the hepatic histomorphometric changes, oxidative stress and inflammatory parameters of C. gariepinus juveniles. One hundred juveniles of mixed sexes, assigned into 5 groups of 20 fish per group, with each group consisting of 2 replicates of 10 fish, were used for the investigation. Group A juveniles were fed basal diet, while groups B-E received basal diet incorporated with sodium propanoate at the rate of 25, 50, 75 and 100 g/15 kg of feed respectively. Treatments were done two times daily for 8 weeks. Samples (sera and liver) were collected on the last day for evaluation of a few biochemical parameters (malondialdehyde values, catalase activity, C-reactive protein levels) and histomorphometric alterations in the liver. Results indicated that fish in groups D and E had higher catalase activities, lower serum levels of C-reactive proteins and an intact hepatic histomorphormetry when compared with the control group. There was no significant difference in the plasma malondialdehyde values in all the groups. It was concluded that preservation of fish feed with sodium propanoates improved antioxidant status of C. gariepinus and protected liver histology.

Abstract This study was performed to investigate the effects of dietary supplementation with garlic and turmeric powder as growth promoter agents on performance, carcass traits, serum biochemistry, and antioxidant enzyme activities of growing rabbits. A total of 112 New Zealand White rabbits (NZW) at 5 weeks of age were randomly assigned to seven treatments with four replicates. The dietary treatments consisted of 7 groups as follows; the basal diet as control, phytogenic additives groups were supplemented with 2, 4, and 6 g/kg garlic or turmeric powder added to the basal diet. There were no linear and quadratic differences (P<0.05) in growth performance after garlic or turmeric supplementation at all studied ages. Compared with the control group, supplementation of diets with garlic or turmeric linearly and quadratically elevated immunity biomarkers such as total protein (TP), albumin (AL) and immunoglobulin (IgG) levels and decreased (linearly and quadratically, P<0.05) aspartate aminotransferase (AST), alanine aminotransferase (ALT ), triglyceride (TG) and total cholesterol (TC) levels in rabbit serum. However, TP, AL, globulin (GL), IgG and IgM levels were linearly and quadratically enhanced with increasing turmeric levels versus the control diet. Hepatic superoxide dismutase (SOD), catalase (CAT ) and glutathione peroxidase GSH-Px activities as well as reduced glutathione (GSH) concentrations were linearly and quadratically (P<0.05) improved in garlic or turmeric additives fed groups. While MDA concentration was statistically (linearly, P= 0.022) reduced in comparison with the control group. It could be concluded that garlic or turmeric supplementation (2, 4 and 6 g/kg) did not linearly and quadratically affect growth performance but improved the immunity responses and lowered the lipid profile in blood and lipid peroxidation in liver and increased hepatic antioxidant activity in treated rabbits.

A study was conducted on 24 fifteen day old crossbred calves that were divided into 4 groups of 6 calves each. The calves were fed different dietary treatments viz T0 (control group) - basal diet, T1 (probiotic group) - basal diet + Lactobacillus acidophilus @ 1 g/calf/day (2 x 1010 cfu/ g), T2 (prebiotic group)- basal diet + Mannan oligosaccharide (MOS) @ 4 g per calf/day and T3 (synbiotic group) basal diet + Lactobacillus acidophilus @ 0.5 gm (2 x 1010 cfu/ g) + 2 g MOS per calf/day respectively for a period of 90 days. Blood samples were taken at monthly interval and serum was separated to estimate different biochemical parameters. The results of study indicated that probiotic (Lactobacillus acidophilus), prebiotic (MOS) and synbiotic supplementation were effective in reduction of serum cholesterol and triglycerides at 60th and 90th day. Serum creatinine, glucose, urea and bilirubin were unaffected by dietary supplementation of probiotic, prebiotic (MOS) and synbiotic. There was no effect of T1, T2 and T3 supplementation on Serum enzymes, Aspartate aminotransferase (AST) and Alanine Amino Transferase (ALT).

This study was conducted to investigate the effects of dietary supplementation with different types of Bacillus subtilis (B. subtilis) on the growth and gut health of weaned piglets. A total of 160 piglets were randomly assigned into four groups: control group (a basal diet), BS-A group (a basal diet supplemented with B. subtilis A at 1 × 106 CFU/g feed), BS-B group (a basal diet supplemented with B. subtilis B at 1 × 106 CFU/g feed), and BS-C group (a basal diet supplemented with B. subtilis C at 1 × 106 CFU/g feed). All groups had five replicates with eight piglets per replicate. On days 7, 21, and 42 of the trial, blood plasma and intestinal tissues and digesta samples were collected to determine plasma cytokine concentrations, intestinal morphology, gut microbiota community and metabolic activity, and the expression of genes related to gut physiology and metabolism. The results showed that dietary B. subtilis supplementation improved (P &lt; 0.05) the body weight and average daily gain (in BS-B and BS-C groups) of weaned piglets and decreased (P &lt; 0.05) the diarrhea rates (in BS-A, BS-B, and BS-C groups). In the intestinal morphology analysis, B. subtilis supplementation improved (P &lt; 0.05) the size of villus height and villus height to crypt depth ratio in the ileum of weaned piglets. Firmicutes, Bacteroidetes, and Tenericutes were the most dominant microflora in piglets' colon whatever the trial group and time of analysis. Dietary BS-C supplementation increased (P &lt; 0.05) the relative abundances of Anaerovibrio and Bulleidia and decreased (P &lt; 0.05) the relative abundances of Clostridium and Coprococcus compared with the control group. In addition, dietary B. subtilis supplementation increased (P &lt; 0.05) the indicators of intestinal health, including plasma levels of interleukin (IL)-2 and IL-10, as well as the colonic levels of short-chain fatty acids. Furthermore, dietary B. subtilis supplementation also up-regulated (P &lt; 0.05) the expression of genes involved in metabolic pathways related to intestinal microbiota maturation. In conclusion, these findings suggest that a diet containing BS-B or BS-C can efficiently promote growth performance, decrease diarrhea incidence, and ameliorate several indicators of intestinal health through the modulation of gut microbiota composition and metabolic activity in weaned piglets.

Abstract The objective of this study was to determine the effects of quercetin on oxidative stress and apoptosis induced by TPT in zebrafish. 240 fish were divided into 4 groups with three repeats. D1: fish fed with the basal diet as the control group. D2: fish fed with basal diet and exposed in 10 ng/L TPT. D3: fish fed diets containing 100 mg/Kg quercetin and exposed in 10ng/L TPT. D4: fish fed diets containing 100 mg/Kg quercetin. The results showed that quercetin could ameliorate oxidative stress, which decreased MDA, NO levels and improved antioxidant enzyme activities. The key apoptotic gene expressions, including caspase3, Bax and caspase9 mRNA expression were significantly induced by TPT exposure as compared with the control group, while notably decreased the Bcl-2 gene. However, dietary quercetin prevented a significant increase in Bax, caspase3 and caspase9 mRNA levels induced by TPT exposure, but increased Bcl-2 mRNA levels. The results of our study also demonstrated that 10 ng/L TPT significantly up-regulated TNF-α, IL-1β, IL-8, and NF-kB p65 gene expression and down-regulated IL-10 and IkB expression compared to the control group. However, TPT-induced inflammation was significantly mitigated in the quercetin treatment group. In conclusion, our findings suggested that quercetin might alleviate hepatic oxidative damage and apoptosis induced by TPT.
