Effects of chicory (Cichorium intybus L.) distillation wastewater on antioxidant status, immune response, cecal microbial population, growth performance and meat quality in broiler chickens

Chicory (Cichorium intybus L.) distillation wastewater (CDWW) is a dark viscous liquid obtained as a by-product of the processing of industrial chicory (Cichorium intybus). The current study aimed to investigate the influence of dietary CDWW on growth performance, oxidative status, immune response, meat quality, and cecal microbial population of broiler chicken. In total, 400 one-d-old male chickens (Ross 308) were allotted into four groups in ten replicates of 10 chickens each. The 1st group was fed a basal diet without CDWW (control), whereas the 2nd, 3rd, and 4th groups were fed diets containing CDWW (15, 30, and 45 mL/kg diet, respectively) for 42 days. At day 42 of age, CDWW significantly increased body weight gain (P < 0.01), improved feed efficiency, and reduced mortality rate (P < 0.05). Treatments did not have a significant effect on feed intake. The 30 and 45 mL of CDWW groups showed an increase in hematological values than other groups (P < 0.05). The ALT, AST, ALP, triglyceride, and cholesterol concentration in serum were lower and immunoglobulins (IgA, IgG, IgM) were greater in 30 and 45 mL /kg of CDWW groups than other groups (P < 0.05). The malondialdehyde (MDA) content in serum, liver, breast, and lipid peroxide (LPO) in breast decreased by 30 and 45 mL of CDWW supplementation (P < 0.05). The oxidative enzymes activities in serum, liver, and breast were greater in 30 and 45 mL /kg of CDWW than other groups (P < 0.05). Also, quality properties and composition of beast were improved and ceceal harmful microbial counts were decreased by the 30 and 45 mL /kg of CDWW (P < 0.05). In conclusion, the CDWW at 30 and 45 mL /kg improved the broiler's performance, meat quality, as well as blood indices and cecal microbial load by enhancing antioxidant activities and suppressing lipid peroxidation in meat.

Characterization of the Effects of Low-Sodium Salt Substitution on Sensory Quality, Protein Oxidation, and Hydrolysis of Air-Dried Chicken Meat and Its Molecular Mechanisms Based on Tandem Mass Tagging-Labeled Quantitative Proteomics.

The effects of low-sodium salt mixture substitution on the sensory quality, protein oxidation, and hydrolysis of air-dried chicken and its molecular mechanisms were investigated based on tandem mass tagging (TMT) quantitative proteomics. The composite salt formulated with 1.6% KCl, 0.8% MgCl2, and 5.6% NaCl was found to improve the freshness and texture quality scores. Low-sodium salt mixture substitution significantly decreased the carbonyl content (1.52 nmol/mg), surface hydrophobicity (102.58 μg), and dimeric tyrosine content (2.69 A.U.), and significantly increased the sulfhydryl content (74.46 nmol/mg) and tryptophan fluorescence intensity, suggesting that protein oxidation was inhibited. Furthermore, low-sodium salt mixture substitution significantly increased the protein hydrolysis index (0.067), and cathepsin B and L activities (102.13 U/g and 349.25 U/g), suggesting that protein hydrolysis was facilitated. The correlation results showed that changes in the degree of protein hydrolysis and protein oxidation were closely related to sensory quality. TMT quantitative proteomics indicated that the degradation of myosin and titin as well as changes in the activities of the enzymes, CNDP2, DPP7, ABHD12B, FADH2A, and AASS, were responsible for the changes in the taste quality. In addition, CNDP2, ALDH1A1, and NMNAT1 are key enzymes that reduce protein oxidation. Overall, KCl and MgCl2 composite salt substitution is an effective method for producing low-sodium air-dried chicken.

Growth performance, meat quality and hematological parameters of broiler chickens fed safflower seed.

The aim of the current study was to determine the effects of dietary supplementation of safflower seed (SS) on the growth performance and hematological parameters of broiler birds along with the physicochemical, textural and sensory attributes of chicken meat. A total of 200 male chickens (7-days-old) were distributed into 5 groups (40 chickens in each) with 5 replicates of 8 chicks in a 42-day experiment. Each group was allocated to one of 5 dietary treatments, i.e., 0, 2.5, 5, 7.5, and 10% SS. The experimental diets were formulated for starter (7 to 21 days) and finisher (22 to 42 days) phases. Inclusion of SS in the diet improved growth performances in treatment groups between 7 and 42 days. The highest and lowest body weights were observed at the 5% SS and 0% SS levels, respectively. The physicochemical attributes of breast and thigh meat were found (P > 0.05) except for crude fat. The crude fat was significantly (P < 0.05) increased with increasing levels of SS in the diet. The inclusion of SS in the diet did not negatively impact the textural properties, i.e., hardness, cohesiveness, springiness, gumminess, chewiness, and shear force of breast and thigh meat. There was no significant difference in the sensory parameters of cooked chicken meat with increasing levels of SS in the diet. The results demonstrated a significant (P < 0.01) improvement in hematological parameters in the blood samples of broiler chickens fed diet supplemented with various levels of SS for five weeks. These findings suggest that, SS may be used as an oil seed for broiler chicken feed.

Novel insights into heat tolerance: the impact of dwarf and frizzled feather traits on crossbreed chicken performance under thermal stress

Heat stress (HS) poses significant challenges to broiler production, negatively influencing growth performance and meat quality. This study explores the resilience and the meat quality of hybrid chickens with dwarf size and frizzled feather traits to HS. We investigated F1 progeny derived from a crossbreed of dwarf yellow chickens (DYCs) with Yuexi frizzled feather chickens. Following a rearing period of 12 weeks, we randomly assigned 72 chickens into two distinct environmental conditions: a HS group subjected to 35 ± 1 °C for 8 h per day, and a control group (CN) maintained at 26 ± 1 °C. Seven days post-HS, multiple tissue samples were collected to assess meat quality attributes and measure expression levels of heat shock proteins (HSPs), muscle growth-related genes and cytokines. The results demonstrated a substantial reduction in weight gain of the F1 chickens exposed to HS, along with decreased expression of insulin-like growth factor-1 (IGF-1) and its receptor (IGF-1R) in the liver. Furthermore, HS exposure significantly increased muscle shear force and the expression of HSP70 in both liver and pectoral muscle tissues (p < .05). Despite these changes, there were no significant alterations in the other meat quality indices, or indicators of splenic and hepatic tissue injury. Likewise, expression levels of growth hormone receptor (GHR) and cytokines remained stable, implying a lack of heightened inflammation. These observations suggest an inherent thermotolerance in the chickens possessing dwarf size and frizzled feather traits, warranting further exploration for their potential in heat-stress-prone poultry production environments. Highlights Dwarf and frizzled feather traits in crossbreed chickens show potential for improved heat tolerance in poultry production. Heat stress had limited impact on meat quality parameters, suggesting resilience of these local chicken traits. Understanding the genetic basis of thermotolerance can inform breeding strategies for climate-resilient chickens.

The effects of cricket meal (Gryllus sigillatus) on the meat quality, growth, and internal morphology of broiler chickens

Cricket ( Gryllus sigillatus) meal (CM) was fed to Ross 308 broiler chickens ( n = 624 total; 26 birds/pen) at dietary inclusion rates of 0% (non-medicated control; NM), 0% (medicated control; 0.05% virginiamycin, 0.03% monensin; M), 5%, 10%, 15%, and 20% CM (non-medicated) for 35 days to determine the impact of this novel feed ingredient on the growth, feed intake, organ indices, and meat quality of these chickens. The final average live weight of broilers fed 5% CM was lower than broilers fed the 10% CM ( P &lt; 0.05) and the 0% NM diets ( P &lt; 0.05). Total weight gain was lowest in chickens fed 5% CM ( P &lt; 0.05) and the % ratio of the weight of the small intestine to body weight of the chickens fed 5% CM was significantly higher on day 20 than that of the other treatments ( P &lt; 0.05). Meat texture and colour were not affected by dietary treatments. Cooking loss in birds fed the 10% CM diet was significantly higher than that of birds fed the 0% NM control. Feeding up to 20% CM did not alter the growth, organ indices, or meat quality of broiler chickens, although further research is required to determine whether including &gt;20% CM in the diet will produce similar results.

The variables observed were broiler chicken carcasses, physical properties of chicken meat (commercial cuts, and the chemical quality of meat (protein, fat, cholesterol) and the microbial content (TPC) marketed. obtained. Research result had a not significantly different (P&gt;0.05) on carcass weight, percentage carcass, and meet microba of broiler. From this study, it can be concluded that the carcass production of broiler chickens sold in Lapak in Denpasar North, Denpasar, Timur, Denpasar Barat and Denpasar Selatan had no effect on the weight of the cut, carcass fracture of the back, wing, and percentage of broiler chicken fracture.

A machine learning approach to uncover nicotinamide and other antioxidants as novel markers for chicken meat quality assessment

This study analyses various chicken cuts (breast, leg, and thigh) in terms of ten biocompounds: nicotinamide, anserine, carnosine, malondialdehyde, and biogenic amines (putrescine, cadaverine, histamine, tyramine, spermidine, and spermine). The analysis is conducted on refrigerated chicken meat cuts using three different packaging solutions: modified atmosphere packaging (MAP), vacuum skin packaging (SKIN), and permeable O2 plastic film (STRETCH). Our results show that nicotinamide was the most discriminant compound followed for cuts and time. Remarkably, its concentration decreases over time, unaffected by any of the packaging solutions. The collective contribution of all the examined biocompounds is highlighted through multivariate statistical analysis, utilizing partial least square discriminant analysis (PLS-DA) and the support vector machine (SVM) algorithm. Both machine learning models demonstrate high classification accuracy: for cut, storage time, and packaging, PLS-DA yields classification accuracy rates of 87%, 85%, and 70%, respectively. SVM achieves even higher accuracy rates of 97%, 99%, and 94% for cut, storage time, and packaging, respectively. These results underscore the importance of considering the combined influence of all the biocompounds investigated in this study for a finer classification of chicken meat cuts and packaging. Furthermore, our findings highlight the efficacy of SVM as a discriminant multivariate approach in food classification.

Effects of intermittent cold stimulation on growth performance, meat quality, antioxidant capacity and liver lipid metabolism in broiler chickens

Intermittent cold stimulation (ICS) enhances broilers’ resistance to cold stress. Nonetheless, further research is needed to investigate the underlying mechanisms that enhance cold stress resistance. A total of 160 one-day-old male Ross 308 broilers were randomly divided into two groups (CC and CS5), with the CC group managing temperature according to the standard for broiler growth stages, while the CS5 group were subjected to cold stimulation at a temperature 3℃ lower than the CC group for 5 h, every two days from 15-35 day. Sampling was conducted at 36 day (36D), 50 day (50D) and after acute cold stress for 24 h (Y24). First, we examined the effects of ICS on broiler growth performance, meat quality, antioxidant capacity, and lipid metabolism. The results demonstrated that ICS enhanced the performance of broilers to a certain degree. Specifically, the average weight gain in the CS5 group was significantly higher than that of the CC group, and the feed conversion ratio significantly decreased compared to CC at 4 W and 6 W (P ≤ 0.05). Compared with the CC group, cold stimulation significantly reduced drip loss, shearing force, and yellowness (a* value) of chicken meat, while significantly increased redness (b* value) (P ≤ 0.05). At Y24, the levels of T-AOC and GSH-PX in the serum of the CS5 group were significantly higher than those of the CC group, while the level of MDA was significantly lower (P ≤ 0.05). The content of TG, FFA, and VLDL in the serum of the CS5 group was significantly elevated, whereas the level of TC and HDL was significantly lower (P ≤ 0.05). In addition, we further explored whether AMPK-mTOR pathway is involved in the regulation of changes in lipid metabolism and the possible regulatory mechanisms downstream of the signaling pathway. The results showed that ICS significantly upregulated the expression levels of AMPK mRNA and protein in the liver of the CS5 group at 36D and Y24, while significantly down-regulating mTOR (P ≤ 0.05). Compared with the CC group, ICS significantly down-regulated the mRNA expression levels of lipid synthesis and endoplasmic reticulum stress-related genes (SREBP1c, FAS, SCD, ACC, GRP78 and PERK) at 36D and Y24, while significantly up-regulating the mRNA expression levels of lipid decomposition and autophagy-related genes (PPAR and LC3) (P ≤ 0.05). In addition, at Y24, the protein expression levels of endoplasmic reticulum stress-related genes (GRP78) in the CS5 group were significantly lower, while autophagy-related genes (LC3 and ATG7) were significantly higher (P ≤ 0.05). ICS can affect meat quality and lipid metabolism in broilers, and when broilers are subjected to acute cold stress, broilers trained with cold stimulation have stronger lipid metabolism capacity.

Effects of Dietary Lycopene on the Growth Performance, Antioxidant Capacity, Meat Quality, Intestine Histomorphology, and Cecal Microbiota in Broiler Chickens.

The experiment aimed to investigate the effects of dietary lycopene on the growth performance, antioxidant capacity, meat quality, intestine histomorphology, and cecal microbiota in broiler chickens. We randomly divided five hundred and seventy-six one-day-old male broilers into four groups each with six replicates and 24 chickens in each replicate. The control group (CG) was fed the basal diet, and the other groups were given powder lycopene of 10, 20, and 30 mg/kg lycopene (LP10, LP20, and LP30, respectively). Compared with the control group, (1) the dietary lycopene increased (p = 0.001) the average daily gain and decreased (p = 0.033) the feed conversion ratio in the experimental groups; (2) the glutathione peroxidase enzyme contents in LP20 were higher (p =< 0.001) in myocardium; (3) the crude protein contents were higher (p = 0.007) in the group treated with 30 mg/kg dietary lycopene; (4) the jejunum villous height was higher (p = 0.040) in LP20; (5) the Unclassified-f-Ruminococcaceae relative abundance was significantly higher (p = 0.043) in LP20. In this study, adding 20 mg/kg dietary lycopene to the broiler chickens' diets improved the growth performance, antioxidant capacity, meat quality, intestine histomorphology, and cecal microbiota in broiler chickens.

Effects of Acacia mearnsii tannins on growth performance, footpad dermatitis, nutrient digestibility, intestinal permeability, and meat quality of broiler chickens

An experiment was conducted to evaluate the effects of increasing dietary supplementation of tannins from Acacia mearnsii on broiler growth performance, footpad dermatitis, litter moisture, and ileal digestibility as well as on intestinal permeability, jejunal morphometric, and lipid oxidation measurements. A total of 1620 Cobb 500 one-day-old male chicks were fed 6 experimental diets with 10 replicate pens of 27 birds each in a 4-phase feeding program. Dietary treatments were as follow: non-challenged control, challenged control, and challenged supplemented with 300, 500, 700, or 900 mg/kg tannin from Acacia mearnsii. All birds on challenged groups were challenged with Eimeria spp. on day 1 and Clostridium perfringens on days 11, 12, and 13. Performance was evaluated weekly until day 43. On day 21, blood samples were collected for biochemistry analyses and the intestinal permeability was evaluated using FITC-d as marker. Ileal digestibility and jejunal morphometric were also determined on day 21. Footpad dermatitis, litter moisture, and litter pH were evaluated on days 28, 35, and 43. On day 44, carcass and commercial cuts weights were evaluated and thigh samples were collected for lipid oxidation (TBARS) through a 6 months storage period. Broilers under intestinal challenge had lower growth performance, higher intestinal permeability, and lower serum albumin, cholesterol, glucose, and triglycerides compared to non-challenged birds (P < 0.05). From day 1 to 43, increasing tannin supplementation for broilers under intestinal challenge led to quadratic increases (P < 0.05) in body weight gain, with optimal supplementation at 310 mg/kg as well as optimized estimations for feed conversion ratio at 444 mg/kg tannin. Dietary tannin supplementation that reduced intestinal permeability at 21 days was 466 mg/kg (P < 0.05). Tannin supplementation that improved protein and energy digestibility were at 374 and 294 mg/kg, respectively (P < 0.05). No effects of tannin were observed on blood biochemistry, crypt depth, litter pH, carcass measurements, and lipid oxidation until the storage day 60. However, increasing levels of tannin supplementation led to a linear (P < 0.05) decrease on lipid oxidation of broiler meat after 90 days of storage. In conclusion, low levels of supplemental tannins from Acacia mearnsii improved growth performance, nutrient digestibility, and intestinal permeability in broilers under an intestinal challenge.

Transcriptome analysis reveals the role of long noncoding RNAs in specific deposition of inosine monphosphate in Jingyuan chickens.

Inosine monphosphate (IMP) is one of the important indicators for evaluating meat flavor, and long noncoding RNAs (lncRNAs) play an important role in its transcription and post-transcriptional regulation. Currently, there is little information about how lncRNA regulates the specific deposition of IMP in chicken muscle. In this study, we used transcriptome sequencing to analyze the lncRNAs of the breast and leg muscles of the Jingyuan chicken and identified a total of 357 differentially expressed lncRNAs (DELs), of which 158 were up-regulated and 199 were down-regulated. There were 2,203 and 7,377 cis- and trans-regulated target genes of lncRNAs, respectively, and we identified the lncRNA target genes that are involved in NEGF signaling pathway, glycolysis/glucoseogenesis, and biosynthesis of amino acids pathways. Meanwhile, 621 pairs of lncRNA-miRNA-mRNA interaction networks were constructed with target genes involved in purine metabolism, fatty acid metabolism, and biosynthesis of amino acids. Next, three interacting meso-networks gga-miR-1603-LNC_000324-PGM1, gga-miR-1768-LNC_000324-PGM1, and gga-miR-21-LNC_011339-AMPD1 were identified as closely associated with IMP-specific deposition. Both differentially expressed genes (DEGs) PGM1 and AMPD1 were significantly enriched in IMP synthesis and metabolism-related pathways, and participated in the anabolic process of IMP in the form of organic matter synthesis and energy metabolism. This study obtained lncRNAs and target genes affecting IMP-specific deposition in Jingyuan chickens based on transcriptome analysis, which deepened our insight into the role of lncRNAs in chicken meat quality.

Dietary supplementation with natural antioxidants: assessment of growth performance and meat quality in broiler chickens

Exposure to air and light lowers the meat quality of chickens, which is mainly determined by the color alteration and accumulation of detrimental products from lipid oxidation. This study tests the effects of two supplements rich in polyphenols, Oxilem (OX) and OxiGem (OG), on broiler Ross 308 performance and meat quality in comparison to a control group (C). A total of 105 one-day-old Ross 308 male chicks were allocated to 21 pens and randomly assigned to one of the three treatments. The trial lasted 42 days. Individual live weight and feed intake per pen were recorded. Proximate analysis, color, cholesterol content and cholesterol oxidation products (COPs), fatty acids (FAs), volatile aldehydes profile, and secondary oxidation products of meat FAs were determined, with analyses for detecting oxidative alterations conducted on breast burgers preserved for seven days at 4°C. Birds fed OG grew 7 g/day more than those receiving OX, reaching a higher final weight. After slaughtering, meat from the OX group had a higher yellow index compared to C. After seven days of air and light exposure, the influence on the color parameters of the OG and OX burgers was significantly less pronounced than that of C. Secondary oxidation products of the FAs of the burgers were not significantly affected by the diet regimens. In addition, OX and OG burgers exhibited lower amounts of volatile aldehydes, triol and COPs. These results confirm the effectiveness of OX and OG supplementation against lipid oxidation at the inclusion level used in this trial.

Growth performance and meat quality of broiler chickens fed diet containing bird eye pepper of varying proportion and sieve size.

This study investigated the potency of bird eye pepper (BEP) of varying proportion and sieve size on growth performance and meat quality of broiler chickens. Two hundred and forty-six 2-wk-old broiler chicks were randomly allotted to six treatment groups (basal diet (B) inclusive×2) in a 2×3 factorial arrangement each replicated four times (10 × 10 × 10 × 11) in a completely randomized design. Diets containing BEP of varying proportion (0, 150, and 300g) and sieve size (0.05 and 0.1mm) were offered in two phases, starter (14d) and finisher (17d). Postfeeding, 48 birds (two per replicate) were sacrificed to further evaluate performance and assess the quality of meat produced. Result obtained indicates chicks fed 150g BEP consumed less feed compared to 300g BEP. Also, 0 and 150g BEP groups had better (P < 0.05) feed conversion ratio (FCR) than 300g BEP, while 0.05mm BEP diet improved (P < 0.05) FCR as against 0.1mm BEP. Interaction of proportion and sieve size effects of BEP increased (P < 0.05) the final weight of the birds and suppressed (P < 0.05) feed intake for all groups as against 300g (0.1mm) BEP (1,576.00g/bird; 964.20g/bird). Feeding 150 and 300g BEP diets lowered (P < 0.05) superoxide dismutase (SOD) production compared to 0g BEP, while 150g BEP diet increased (P < 0.05) catalase production over 0g BEP. Interactive effect of proportion and sieve size of BEP reduced (P < 0.05) SOD production in 150g (0.05 and 0.1mm) BEP and 300g (0.05mm) BEP groups, followed by 300g (0.1mm) BEP group that had lower (P < 0.05) SOD than both basal groups. Birds fed B + 150g (0.05mm) BEP diet produced more (P < 0.05) catalase compared to both basal groups. Meat pH for 150 and 300g BEP groups was significantly (P < 0.05) reduced than 0g BEP. The Hue angle corresponds with a high value (P < 0.05) to 0g BEP, while 300g BEP showed a low value. This study has shown BEP at low concentration (150g) screened with 0.05 and 0.1mm sieves enhanced chick welfare, while a higher concentration (300g) screened at 0.05mm improved overall growth performance (endogenous antioxidant profile) at finisher phase. Broiler chickens, farmers, and meat processors will benefit from diet containing BEP screened through 0.05mm sieve.
