Effects of Feeding Fermented Mulberry Leaf Powder on Growth Performance, Slaughter Performance, and Meat Quality in Chicken Broilers

This study was conducted to investigate the effects of feeding fermented mulberry leaf powder (FMLP) on growth performance, slaughter performance, and meat quality of broilers. A total of 360 1-day-old chickens were randomly divided into 5 groups. The control group was fed basal diet (CON), 3% FMLP, 6% FMLP, 9% FMLP, and 3% unfermented mulberry leaf powder. The (MLP) group was fed basal diet supplemented with 3%, 6%, 9% fermented mulberry leaf powder, and 3% MLP, respectively. The experiment lasted for 56 days, with 1–28 days as the starter phase and 29–56 days as the grower phase. The results on the growth performance showed that diets supplemented with 3% FMLP significantly increased the ratio of villus height to crypt depth in the duodenum, jejunum, and ileum of broilers, enhanced the activity of intestinal amylase and digestibility of dry matter and crude protein, improved the average daily gain (ADG), and decreased the feed to gain ratio (F/G) (p < 0.05). Compared with the control group diet, the 3% FMLP group diet significantly increased the breast muscle yield (p < 0.05), reduced the abdominal fat ratio (0.1 < p < 0.05), and improved the slaughter performance of broilers. The 3% MLP group diet increased the shear force of breast muscle (p < 0.05) and thigh muscle of broilers compared to the control group, and adding FMLP could reverse the above results. Additionally, relative to the control group, FMLP supplementation improved the contents of inosine monophosphate (IMP), total amino acids (TAA), essential amino acids (EAA), and delicious amino acids (DAA) in breast and thigh muscle, and improved polyunsaturated fatty acids (PUFA) and essential fatty acids (EFA) in breast muscle; the 6% and 9% FMLP groups showed preferably such effects (p < 0.05). In conclusion, dietary supplementation of FMLP can improve the digestion and absorption of nutrients, and then improve the growth performance of broilers; it also has a positive effect on improving slaughter performance and meat quality.

Dietary curcumin altered the growth performance and meat quality. However, study on the effect of dietary curcumin on the growth performance, serum antioxidation and meat quality of ducks. This study invested effects of dietary curcumin given to ducks on the growth performance, antioxidation capacity in plasma, meat quality, lipid oxidation and the concentration of volatile compounds in duck breast muscle. A total of 600 healthy ducks with similar body weight were randomly allotted into 4 groups with 10 replicates per group and 15 ducks per replicate. Ducks were fed experimental diets which the curcumin supplemental levels were 0, 300, 400 and 500 mg curcumin/kg basic fed, respectively. The experiment lasted for 10 weeks. Results: Results showed that dietary supplementation of curcumin at levels 300, 400 and 500 mg/kg dietary (P < 0.05) improved the average final body weight. The ducks fed the basal diet without curcumin supplementation had the lowest FI (P > 0.05) and highest FCR (P > 0.05) among all ducks. Feeding ducks on diets supplemented with curcumin at each level significantly increased (P < 0.05) plasma activity of T-SOD and GSH-Px, and significantly reduced plasma MDA concentration compared to the control group. The dietary curcumin significantly increased the growth performance and the antioxidation capacity in plasma of ducks. Dietary curcumin improved the meat quality of ducks by significantly increasing pH45, pH24 (P < 0.05) and color of duck meat (P < 0.05), and significantly decreasing cooking loss (P < 0.05), shear force (P < 0.05), and the lipid oxidation of duck meat. 56 volatile compounds were identified and quantified. Interestingly, cantharidin among volatile compounds was firstly found in duck muscle, and only existed in the group of 500 mg curcumin/kg diet. Conclusions: In conclusion, the supplementation of duck diets with curcumin at 300, 400, and 500 mg/kg diet improved growth performance, antioxidant status and meat quality of ducks. The cantharidin was firstly found in duck breast muscle when the dietary curcumin inclusion of 500 mg/kg.

To determine whether Lactobacillus johnsonii BS15 supplementation improves the growth performance and meat quality of broilers, 450 1-day-old male chicks (Cobb 500) were randomly divided into three groups: control group (basal corn-soybean diet), L-BS15 group (basal diet + 1 × 105 colony-forming unit BS15/g as feed), and H-BS15 group (basal diet + 1 × 106 colony-forming unit BS15/g as feed). These diets were fed for 42 days. Abdominal fat decreased (P < 0.05) as the concentration of BS15 increased. BS15 supplementation significantly increased the pH at 24 h after sacrifice and decreased drip loss and shearing force (P < 0.05), although meat colour and pH at 40 min after sacrifice remained unchanged. Antioxidant capacity and total protein and intramuscular fat levels were unchanged by the treatments, but BS15 supplementation significantly increased inosine monophosphate level and decreased total cholesterol and triglyceride levels (P < 0.05). The levels of proline, total amino acids, and flavour-related amino acids were increased (P < 0.05) by BS15 supplementation, but the levels of other amino acids did not change significantly. BS15 supplementation significantly decreased (P < 0.05) C16:0, C22:4n-6, and n-6 : n-3 ratio and increased (P < 0.05) C18:3n-3, C20:5n-3,C22:6n-3, total polyunsaturated fatty acid (PUFA), n-3 PUFA and PUFA : saturated fatty acid ratio. These findings suggest that L. johnsonii BS15 supplementation improves the meat quality of broilers by increasing the shelf life and flavour and nutritional substances. In addition, BS15 supplementation can induce changes in fat deposits and fatty acid composition.

This study aimed to investigate the effects of dietary supplementation with dl-methionine (dl-Met) and dl-methionyl-dl-methionine (dl-Met-Met) in breeding pigeons on the carcass characteristics, meat quality and antioxidant activity of squabs. A total of 324 pairs of breeding pigeons were selected and allotted to 9 treatments in a completely randomized design, and the birds were fed dietary treatments for 45 d, including a Met-deficient basal diet (BD, crude protein = 15%, Met = 0.25%) and BD + 0.15%, 0.30%, 0.45%, or 0.60% dl-Met or dl-Met-Met diets. Compared with the diet fed to the BD group, dietary dl-Met or dl-Met-Met supplementation effectively increased the carcass yield, semieviscerated yield, eviscerated yield, breast muscle yield, thigh muscle yield, a* value, catalase activity, total superoxide dismutase activity and glutathione peroxidase activity, but decreased the L* value, malonaldehyde concentration, drip loss and cooking loss of squabs (p < 0.05). The relative bioavailability values of dl-Met-Met relative to those of dl-Met were 467% and 376% based on carcass yield and breast muscle yield, respectively (p < 0.001). Moreover, dl-Met-Met was more effective than dl-Met in decreasing the drip loss and improving the antioxidant activity of the breast and thigh muscles of squabs (p < 0.05). As a source of Met, dl-Met-Met, rather than dl-Met, was more beneficial to squabs.

Encoding Genes

Chronic heat stress (CHS) induces metabolic changes in skeletal muscle from growth to maintenance that jeopardizes growth performance, carcass traits, and meat quality of pigs. We investigated the protective effect of dietary organic selenium (hydroxy-4-methylselenobutanoic acid, OH-SeMet) on CHS-induced skeletal muscle damages of growing pigs, and the corresponding responses of selenoproteins. A total of 40 ((Landrace × Yorkshire) × Duroc) pigs with an average live weight of 49.64 ± 2.48 kg were used in this 4-week trial. Pigs were randomly allotted to 5 groups: The control group was raised on a basal diet in a thermoneutral environment (22 ± 2 °C); and four CHS groups were raised on a basal diet and supplemented with Se 0.0, 0.2, 0.4, and 0.6 mg/kg as OH-SeMet, respectively, in hyperthermal condition (33 ± 2 °C). CHS resulted in significant decrease of growth performance, carcass traits, and meat quality, which were associated with reduced (p < 0.05) serum alkaline phosphatase (ALP) and total superoxide dismutase (T-SOD) and increased (p < 0.05) serum creatine (CK), sarcous heat shock protein 70 (HSP70), glucokinase (GCK), phosphoenolpyruvate carboxykinase (PEPCK), and malondialdehyde (MDA) contents. Meanwhile, four metabolism-related genes and seven selenoprotein encoding genes were abnormally expressed in skeletal muscle. Dietary OH-SeMet addition partially alleviated the negative impact of CHS on carcass traits and improved meat quality. These improvements were accompanied by the increase in Se deposition, the anti-oxidative capacity of serum and muscle, and protein abundance of GPX1, GPX3, GPX4, and SELENOP. Supplementation with 0.6 mg Se/kg (OH-SeMet) restored the sarcous PEPCK, and 0.4 and 0.6 mg Se/kg (OH-SeMet) restored all abnormally expressed metabolism-related and selenoprotein encoding genes. In summary, dietary supplementation with OH-SeMet beyond Se requirement mitigated CHS-induced depression of carcass traits and meat quality of pigs associated with optimal skeletal metabolism, enhanced antioxidant capacity, and regulation of selenoproteins in skeletal muscle of pigs.

AbstractThe aim of this study was to determine the effect of feeding rabbits with diets containing dried silkworm pupae and mealworm larvae meals on their slaughter value and meat quality. A total of 60 New Zealand White rabbits at 35 days of age were divided into 3 equivalent groups. Control group (C) and two experimental diets included either 4% silkworm pupae meal (diet A) or 4% mealworm larvae meal (diet B). The experiment lasted for 55 days and growth performance as well chemical and amino acid meat composition and the profile of fatty acids were evaluated during the study. The results showed that dietary supplementation of insect meals caused increases in final body weight and carcass meat content in rabbits from the experimental groups. The experimental diets had no effect on the sum of essential amino acids in the studied muscles, but created differences in the level of some amino acids: phenylalanine, lysine, tryptophan, threonine, isoleucine and methionine. The concentration of saturated (SFA) and monounsaturated fatty acids (MUFA) in the muscles was comparable in all the groups. In the tissues of rabbits fed the silkworm meal diet, PUFA-3 concentration increased and cholesterol level decreased. It is concluded that dried silkworm pupae and mealworm larvae meals can be used as feed material in rabbit diets at 4% inclusion level without any adverse effect on growth performance, as well as quality and dietetic value of rabbit meat.

The current study investigated the effect of dietary l-histidine and beta-alanine supplementation on growth performance, meat quality, carnosine content, and gene expression of carnosine-related enzymes in broilers. A two-factor design was adopted in this study. A total of 640 1-day-old male broilers were assigned to eight treatments with factorial arrangement containing four levels of l-histidine (0, 650, 1300, or 1950 mg/kg) and two levels of beta-alanine (0 or 1200 mg/kg) supplementation; 0 mg/kg histidine and/or 0 mg/kg were treated as control groups. Each treatment including eight replicates with 10 birds each and the feeding trial lasted for 42 days. Dietary supplementation with l-histidine and beta-alanine did not affect average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR) of broilers during the grower (22–42 days) and the entire phase (1–42 days), compared with the control group (p > 0.05). The only exception was a significantly reduced ADG in the 1950 mg/kg l-histidine group in the starter period (1–21 days, p < 0.05). l-Histidine at 1950 mg/kg significantly decreased redness (a*) and yellowness (b*) values of the meat at 45 min postmortem (p < 0.05), whereas it increased b* value and pH in breast muscle at 24 h postmortem. Moreover, dietary supplementation with beta-alanine alone or combination with l-histidine significantly increased ΔpH in breast muscle (p < 0.01). Dietary l-histidine markedly increased total superoxide dismutase activity and total antioxidant capacity (T-AOC) both in breast muscle (p < 0.01) and in plasma (p < 0.01), and it decreased malondialdehyde (MDA) concentration in breast muscle (p < 0.01). Dietary addition of beta-alanine, alone or combination, significantly increased T-AOC in breast muscle (p < 0.01) and markedly decreased MDA content both in breast muscle and in plasma (p < 0.01). Addition of l-histidine and beta-alanine significantly increased muscle peptide (carnosine and anserine) content (p < 0.05) and upregulated the expression of carnosine synthase, transporter of carnosine/ l-histidine, and l-histidine decarboxylase genes (p < 0.05), with greater change occurring in the combination group of 1300 mg/kg l-histidine and 1200 mg/kg beta-alanine. Overall, dietary l-histidine and beta-alanine could improve meat quality and antioxidant capacity, enhance the carnosine and anserine content, and upregulate the gene expression of carnosine synthesis-related enzymes in broilers.

Background and Aim: In an era of increasing concerns about food availability globally, poultry meat is being increasingly consumed rather than red meat given its quality in terms of pH, color, and tenderness, conferring consumer satisfaction. The choice of feed is a crucial factor in poultry production. This study investigated the effect of dietary supplementation with breadfruit leaf powder on growth performance, meat quality, and antioxidative activity in Japanese quail. Materials and Methods: A total of 120 day-old quail were used in this study and assigned equally into four treatment groups: Group C fed a basal diet and three treatment groups fed a basal diet supplemented with 2.5% (T1), 5% (T2), or 10% (T3) breadfruit leaf powder. The concentrations of breadfruit leaf powder were 2.5, 5, and 10 g/kg in the basal diet. Quail body weight and feed intake (FI) were evaluated at 1, 21, and 35 days of age at 7 a.m. Pectoral muscle was collected to determine pH, meat color, drip loss, cooking loss, water-holding capacity (WHC), tenderness, and antioxidant levels. All variables were analyzed statistically using ANOVA followed by Duncan's post hoc test (significance set at p<0.05). Results: T3 showed increased body weight gain of quails at 1-21 and 21-35 days (p<0.05). Feeding in the T3 group improved the feed conversion ratio compared with those in the C and T1 groups at the starter phase (p<0.05). Dietary treatment did not affect FI (p>0.05). In the present study, meat redness and WHC were improved in the T3 group (p<0.05). Meanwhile, drip loss, cooking loss, and meat tenderness were improved in the T2 group (p<0.05). The pH45 min, pH24 h, lightness, and yellowness were not influenced by the treatments (p>0.05). The antioxidative activities of superoxide dismutase and malondialdehyde decreased in the T3 group (p<0.05), while no significant difference in glutathione peroxidase level (p>0.05) was identified. Conclusion: Ten grams/kilogram of breadfruit leaf powder, as administered in the T3 group, can be applied as a dietary supplement for Japanese quail to improve growth performance, meat quality, and antioxidative activity during the starter and grower periods.

This study was conducted to investigate the effects of the mulberry [Morus alba var. multicaulis (Perrott.) Loud.] leaf powder (MLP) supplementation in dietary concentrates on growth performance, blood metabolites, meat quality, and antioxidant enzyme (AOE) gene expression in fattening Hu lambs. Forty approximately 3-mo-old Hu lambs (16.5 ± 0.6 kg) were randomly allocated to five groups and fed with concentrates containing 0%, 15%, 30%, 45%, or 60% MLP (control, T15, T30, T45, and T60, respectively). The results showed that 15%–30% MLP supplementation maintained growth and carcass performance, and the weight of total stomach, especially of rumen in T15 and T30, were higher than those of the control. Dietary MLP supplementation decreased serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, cholesterol, and triglyceride levels, but increased the high-density lipoprotein levels. Moreover, MLP supplementation improved the longissimus lumborum muscle color (redness), tenderness, and water-holding capacity. It was further observed that 15% MLP supplementation enhanced all AOE mRNA levels apart from that of EPHX1. In summary, dietary MLP supplementation could partially improve the blood metabolites, meat quality, and AOE mRNA levels in the liver of fattening Hu lamb, and the level of 15% supplementation was the most promising.
