This study aimed at examining the effects of curcumin supplementation on growth performance, antioxidant capacity, and meat quality of ducks. To investigate these effects, 600 healthy ducks were randomly assigned to four treatment groups with 10 replicates pens, and each pen contained 15 ducks. Ducks were fed a diet containing curcumin at levels of 0, 300, 400, and 500 mg kg−1 in different groups. The results demonstrated that curcumin supplementation is beneficial to the growth performance (p < 0.05) of ducks and antioxidant capacity (p < 0.05) of duck meat. In addition, dietary curcumin raised the meat quality of ducks, improving the meat color, increasing water-holding capacity, and inhibiting lipid and protein oxidation. In conclusion, the present study provides important insights into both the nutrient and qualities of ducks, finding that a dietary inclusion of 400–500 mg/kg of curcumin (kg−1) has the greatest effect.

An experiment was conducted with 3840 male Ross × Arbor Acres broiler chicks to test the effects of increasing dietary methionine and lysine on performance and breast meat yield. Supplemental methionine and lysine were fed in a 2 × 4 factorial arrangement in both starter (0–3 wk) and finisher (3–6 wk) diets. Methionine was fed at levels of NRC and 112% NRC. Lysine was fed at levels of NRC and 106% NRC, 112% NRC and 118% NRC. Increasing dietary methionine increased weight gain (P < 0.01), feed efficiency (P < 0.01) from 3 to 6 wk, and breast meat yield (P < 0.01) at 6 wk. Increasing dietary lysine caused a curvilinear response in breast meat yield (P < 0.05). Key words: Broiler, lysine, methionine, breast meat

This research investigates the effects of adding vitamin E, vitamin C, vitamin E+C, and alpha lipoic acid to feed rations for Japanese quails (Coturnix coturnix japonica) exposed to heat stress. The aspects studied were growth performance, carcass composition and breast meat characteristics. Five groups of quails, containing 50 birds each (250 Japanese quails: 150 female and 100 male) were used. The 21-days-old birds were fed for a period of 21 days, and they were kept in a controlled environment with a temperature of 34˚C between 08:00 and 17:00 and a temperature of 24˚C for the remaining part of the day. The five groups under study included: a control group without any additive (BS), a group fed diets with vitamin E (BSE), with vitamin C (BSC), with vitamin E+C (BSEC) and with lipoic acid (BSLA). The supplement additions to the diets did not affect the growth performance and carcass composition of the birds. The TBA (malonaldehyde) value of the BS group was significantly higher (P &lt; 0.001) than in the other groups. L*, a*, and b* values in muscle samples, superficialis pectoralis muscle (SPM) and deep pectoralis muscle (DPM), were determined. In the samples from the SPM, the L* value of the BS group was higher than in the BSC group; the a* value of the BSE group was higher than in the BS group; and the b* value of the BSC group was higher than in the BS group (P &lt; 0.05). In the samples from the DPM, the L* value of the BS group was higher than in the BSEC group (P &lt; 0.05); the a* values of the BSE and BSEC groups were higher than in the BS group (P &lt; 0.05); and the b* values of the BSC, BSEC and BSLA groups were higher than in the BS group (P &lt; 0.01). In the microbiological analysis of meat, total aerobic mesophilic bacterial counts of the BS and BSE groups were higher than the counts in the BSC, BSEC, and BSLA groups (P &lt; 0.01); coliform bacterial counts were higher in the BSE group than in the BSC group (P &lt; 0.05); and lactic acid was higher in the BSE and BSEC groups than in the BSC and BSLA groups (P &lt; 0.01). In conclusion, the supplemented antioxidants did not exhibit any significant effect on growth performance, but they significantly decreased lipid oxidation in the meat. &nbsp;

We compared the physical and chemical characteristics of the pectoralis major muscle from Cobb 500 and Hubbard ISA broilers and evaluated the effect of aging process for up to 7 days on meat quality. We used breast samples from male Cobb 500 (42 days of age; n = 60) and Hubbard ISA (85 days of age; n = 60) broilers. Twenty samples of each genotype were analysed 4 h post-slaughter (Control group). Another 20 samples of each genotype were aged in an incubator (2 ± 0.5°C) for 3 and for 7 days. Breast fillets were 23% heavier in the Cobb 500 group (306 g vs 248 g; P = 0.0009). Before aging, meat from Hubbard ISA broilers had higher (P < 0.001) water-holding capacity, which promotes the production of less exudate and possibly reduces nutritional losses during storage, which may be beneficial to the poultry industry. Despite being initially less tender, breast meat from Hubbard ISA broilers showed, during the aging process, a reduction (P < 0.05) of shear force (48.46–15.04 N), total collagen amount (6.0–4.8 g/kg) and myofibrillar fragmentation index (150.17–97.42) and had the same (P = 0.134) fat concentration (0.87 g/100 g) as that of breast meat from Cobb 500 broilers (0.93 g/100 g, respectively). Breast meat from Hubbard ISA broilers had a higher (P < 0.001) polyunsaturated fatty acid concentration, especially docosahexaenoic acid, which is beneficial to human health. Aging breast fillets for 3 days at 2°C is sufficient to tenderise the meat without reducing its juiciness, which suggests that the aging process can add value to free-range meat.

The effect of partial or complete substitution (2.5% and 5%, respectively) of flaxseed oil for soybean oil on the fatty acid profile, oxidative stability and sensory quality of turkey breast meat was studied. Turkeys were fed experimental diets for 3, 4, 5 or 6 weeks before being slaughtered at 16 weeks of age. The percentages of α-linolenic acid and eicosapentaenoic acid in the total fatty acid pool of meat were determined by dietary intake and feeding duration. Even a prolonged dietary treatment with 5% flaxseed oil did not significantly increase the thiobarbituric acid reactive substances content of the turkey meat and did not have a detrimental effect on the sensory properties. The recommended n-6 : n-3 polyunsaturated fatty acids ratio (<4 : 1) in turkey meat can be easily achieved by feeding turkeys a diet containing 2.5% flaxseed oil for 3 weeks. To maintain the above ratio and increase eicosapentaenoic acid concentrations in the meat, the diet should contain 5% flaxseed oil.

The antilisterial activity of sodium diacetate and a commercial shelf-life extender (ALTA™ 2341) were monitored at 25°C in slurries prepared with turkey breast meat. In slurries prepared without either ingredient, populations of Listeria monocytogenes increased about 5-log10 units in 7 d. The addition of 0.3% diacetate extended the generation time (7 h) compared to the control (no food additives; 1.7 h), whereas 0.5% inhibited the pathogen somewhat (0.4-log10 unit decrease in 7 d compared to the control). Slurries containing ALTA (0.25, 0.5, or 0.75%) and 0.3% diacetate extended the lag phase of L. monocytogenes to a greater extent than slurries with 0.3% diacetate alone. In contrast, 0.5% diacetate in combination with all three levels of ALTA tested was listericidal (ca. 2-log10 unit decrease after 7 d compared to the control). These data confirm the efficacy of diacetate for inhibiting L. monocytogenes in turkey meat and indicate that multiple barriers such as diacetate with ALTA may further lessen the likelihood of food-related listeriosis.

The objective of this study was to investigate the effects of in-package dielectric barrier discharge (DBD) atmospheric cold plasma (CP) on meat color, microbiological quality and safety of chicken breast meat (pectoralis major). Raw broiler breast meat was collected from a local commercial plant. Noninoculated meat samples and meat samples inoculated with Campylobacter and Salmonella were packed in polymeric trays with air. The packaged samples were CP-treated at 70 kV for different times (0, 60, 180, or 300 sec) and stored at 4°C for 5 days. Microbial counts (psychrophiles, Campylobacter, Salmonella) and meat color (International Commission on Illumination (CIE) L∗a∗b∗) were measured before CP treatments and after 5 days of posttreatment storage. Psychrophile growth was inhibited (P<0.05), and both food-borne pathogens were reduced (P<0.05) by more than 90% with CP treatments regardless of treatment time. No differences in pathogenic bacterial counts were observed between the three treatment times; however, increasing treatment time beyond 60 sec resulted in additional inhibition of psychrophilic growth. There were no differences (P>0.05) in a∗ and b∗ values between pretreatment and posttreatment plus storage; however, all CP treatments resulted in increased L∗ value (P<0.05). Results indicate that in-package CP treatments can be used to reduce both microbial spoilage and food-borne pathogen risks, which could increase microbial food safety, although it may result in an overall paler breast meat, and the reduction (about 1 log) in pathogenic and spoilage microbes are limited.
