Moringa oleifera leaf improves meat quality by modulating intestinal microbes in white feather broilers

Exploring effects of dietary coffee pericarp addition on growth, meat quality, gut flora in white-feather broilers

The incorporation of coffee pericarp into poultry diets enhances chicken meat quality by modulating intestinal flora. This study investigates the effects of coffee pericarp on chicken meat quality through an analysis of growth performance, physical parameters, chemical composition, volatile compounds, and gut microbiome. The results demonstrate that adding coffee pericarp to the diet reduces drip loss and pH while improving meat color and increasing the levels of crude protein, amino acids, unsaturated fatty acids, and volatile compounds. Furthermore, coffee pericarp influences the metabolism of these compounds by increasing the relative abundance of beneficial bacteria, such as Firmicutes and Bacteroidetes, thereby enhancing meat quality. In conclusion, incorporating 2.5 % fermented coffee pericarp effectively regulates beneficial bacteria and significantly boosts the volatile compound content in white feather broilers, which is crucial for improving meat flavor and the economic viability of poultry production.

Effects of Qiamagu (Brassica rapa L.) polysaccharide on growth performance, immunity and gut health of yellow-feathered broilers

This study aimed to investigate the effects of adding Qiamagu polysaccharides to feed on the growth performance, immunity and gut health of yellow-feathered broilers. A total of 240 healthy, day-old, male yellow-feathered broiler chickens with similar body weights were randomly divided into four groups, each with six replicates and 10 chickens per replicate. The groups consisted of a control group (CON) and three treatment groups: TP1 (250 mg/kg), TP2 (500 mg/kg), and TP3 (1000 mg/kg) of Qiamagu polysaccharide in the diet, with a feeding period of 64 days. The average daily weight gain of all experimental groups were significantly higher than those of the CON group (P < 0.05) in 1-21 days. The average daily gain of TP1 and TP2 groups was increased (P < 0.05), and the ratio of feed to gain was decreased (P < 0.05), at 43-63 days. The levels of IgM, IgA, IgG, IL-1β, IL-2 and TNF-α in the serum of broilers in the TP1 and TP2 groups exhibited a consistent increase at 21,42 and 63 day (P < 0.05). At 22-42 days, the villus length of duodenum and ileum and the ratio of Villus height to crypt depth ratio were increased in TP2 group (P < 0.05). The ileal mucosa IL-1β and IL-2 mRNA levels of broilers in TP3 group were down-regulated in 1-42 days (P < 0.05). The mRNA levels of MUC2, ZO-1 and Occluding in ileum mucosa of broilers in TP3 group were up-regulated in 1-63days (P < 0.05). The total number of cecal flora species in TP1, TP2 and TP3 groups was higher than that in control group (P < 0.05). The relative abundance of Lactobacillus in TP2 group was increased (P < 0.05). In conclusion, this study showed that the addition of Qiamagu polysaccharide improved the growth performance, enhanced the immune response and had better impact on intestinal health of yellow-feathered broilers.

Dietary Pleurotus citrinopileatus Polysaccharide Improves Growth Performance and Meat Quality Associated with Alterations of Gut Microbiota in Arbor Acre Broilers

Adding edible fungal polysaccharides to animal diets improves growth performance, meat quality, intestinal health, and immunity without adverse effects. This study aimed to evaluate the impact of Pleurotus citrinopileatus polysaccharide (PCP, including PCP250, PCP500, PCP750, and PCP1000 mg/kg) on the growth performance, meat quality, and microbial composition of Arbor Acre (AA) broilers (total 180) by metabolomics and high-throughput sequencing. The results showed that adding PCP enhanced chicken meat tenderness, redness (a*), and water retention and raised essential amino acids and flavor amino acids (such as umami and sweet amino acids) content. The metabolomics revealed that IMP, creatine, betaine, sarcosine, and taurine were related to improving meat quality in broilers by PCP addition. In addition, amino acid, purine, and lipid metabolism were the main metabolic pathways. Moreover, PCP could regulate muscle metabolism by increasing the relative abundance of Lachnospiraceae and Lactobacillus and the content of short-chain fatty acids (SCFAs). Therefore, PCP may become a promising new dietary supplement in the future, which may improve the yield and quality of broiler chickens.

Comparison, optimization and antioxidant activity of ultrasound-assisted natural deep eutectic solvents extraction and traditional method: A greener route for extraction of flavonoid from Moringa oleifera Lam. leaves

To develop an environmentally sustainable and efficient extraction method for flavonoids from Moringa oleifera Lam. (M. oleifera) leaves, natural deep eutectic solvents (NADES) with ultrasound-assisted extraction was utilized in this study. After optimization of extraction parameters of NADES, including ultrasonic power, ultrasonic time, and liquid-solid ratio, the extraction yield of ultrasound-assisted NADES (UAN) composed of betaine and urea (Bet-Urea) reached 54.69 ± 0.19 mg RE/g DW, which made a 1.7-fold increase compared to traditional ultrasound-assisted traditional solvent (UATS). UPLC-Q Exactive/MS analysis revealed that M. oleifera leaves flavonoids (MOLF) was mainly composed of Quercetin 3-β-D-glucoside, Rutin, Kaempferol-3-O-glucoside, Vitexin and Quercetin. Furthermore, the COSMO-RS model was employed to verify the optimal compatibility of solubility and activity coefficient between Bet-Urea and the five primary flavonoids in MOLF. In vitro antioxidant assays verified that MOLF extracted by UAN exhibited superior antioxidant activity compared to MOLF extracted by UATS. Overall, the devised process not only augmented the extraction yield of MOLF but also effectively preserved the bioactive compounds, thus promoting the utilization of green extraction solvents in the food industry.

Walnut meal improves meat quality by modulating intestinal microbes in white feather broilers

Improving the number of amino acids and unsaturated fatty acids in the diet is a good way to raise the quality of the meat. Currently, most research on the quality of broiler meat focuses on genetic traits; nevertheless, it is unclear how meat quality is regulated. This experiment was conducted to investigate the effects of different supplemental levels of walnut meal (WM) on growth performance, amino acid and fatty acid composition, microbial composition, and meat quality of white feather broilers. 1 week old white feather broilers (n = 120; Body weight 83.76 ± 2.32 g), were randomly divided into 3 treatments and 4 replicates. Walnut meal of basic diet (CK), 5 %(WM-L) and 10 %(WM-H) were added to the diets of white feather broilers, respectively. The results showed that walnut meal could increase L* 24 h (24 h brightness) of breast muscle of white feathered broilers (p < 0.05). The amount of essential amino acids (e.g., isoleucine, methionine, leucine, tryptophan, and phenylalanine), umami amino taste acids (glutamic acid), and PUFA/SFA (polyunsaturated fatty acid) (n-3PUFA and n-6 PUFA) in breast muscle increased as the dose was increased. Furthermore, walnut meal regulated amino acid flavour metabolism by increasing the relative abundance of Bacteroides, bifidobacterium, and enterococcus faecalis, according to 16S rRNA sequencing and functional prediction analysis. The correlation showed that amino acid and fatty acid composition was one of the key factors affecting pH value, meat color and tenderness of chicken. In conclusion, dietary addition of walnut meal can increase the content of essential amino acids and unsaturated fatty acids and the relative abundance of beneficial bacteria of broilers, which is of great significance for improving meat quality of white feather broilers.

Effects of Moringa oleifera Leaf Powder on the Growth Performance, Meat Quality, Blood Parameters, and Cecal Bacteria of Broilers

The effect of dietary inclusion of Moringa oleifera leaf powder (MLP) on the growth, meat quality, carcass characteristics, hematobiochemical profile, and cecal bacteria of broiler chicken was investigated in this research trial. In this study, 192-day-old Arbor Acre broiler chicks were assigned in a completely randomized design to three groups: control, antibiotic, and MLP. A standard basal diet was given to the control group, while the antibiotic group received 75 mg/kg chlortetracycline, and the MLP group received 100 mg/kg M. oleifera leaf powder supplemented basal diet. Each group was further divided into eight replicates consisting of eight birds each, and the trial ran for 35 days. Among the groups, the MLP-fed broilers achieved the highest final body weight (FBW), average daily gain (ADG), and average daily feed intake (ADFI). Notably, the FCR for the whole experimental period was lower in the MLP group, indicating a more efficient use of feed for growth. Supplementation of MLP with basal diet significantly increased (p < 0.05) the weight of thighs and drumsticks relative to live weight %, while the spleen and abdominal fat weight (% of live weight) were significantly decreased (p < 0.05). Adding MLP to the diet improved the meat quality of broilers, as indicated by the highest pH of meat at 45 min and the lowest cooking loss (%) observed in this group. MLP exhibited hypocholesterolemic and hypolipidemic effects, with the lowest total cholesterol and triglyceride levels compared to non-supplemented groups. The hematological profile revealed that the MLP group exhibited the highest RBC count and Hb level, while also showing the lowest H/L ratio. Moringa supplementation significantly (p < 0.05) modulated the cecal bacterial population, reducing pathogenic E. coli and Shigella spp. while increasing beneficial Lactobacillus spp. and the total aerobic plate count (TAPC). In conclusion, Moringa oleifera leaf powder (MLP) can be used as a natural feed supplement for promoting the growth, meat quality, healthy blood, and sound health of broilers.
