But the identification of factors related to, meat quality and the PSE condition in poultry will be of, extraordinary achievement of breeding companies to, improve meat quality. Because of the high percentage of red muscle fibres, waterfowl has no disposition for PSE-meat.

Food Res Intern. the ability of producing Se-enriched meat using various bacterial sources of Se as an alternative organic Se supplement, as well as to establish their e ect on the carcass characteristics, meat quality, and meat antioxidant in broiler chicken. Cook yield (%) of AC fillets was significantly higher than cook yield (%) of IC fillets for all deboning times. Overall findings showed that 10% raised in ME by inclusion of oil was adversely influencesthe meat quality and quercetin supplementation exhibited positive impact on carcass characters and meat quality attributes of chickens. 1080 sexed chicks were provided with a common starter diet from 0-4 weeks of age. Collectively, up to 7% lightly oxidized soy oil can be incorporated successfully in the finisher diet of male Lingnan chickens (d 43 to 63 d) as a lower cost energy source in place of fresh SO.

Barring the faster rate of, glycolysis and rigor development in poultry, biochemical, postmortem changes involved in the conversion of muscle, to meat are similar to mammalian species.

Bench-top tool had better performance than portable one, probably because it captured more informative spectral data as shown by the variable importance in projection (VIP) and restricted pool of Stepwise-CDA predictive scores (SPS). It is advisable for farmers to process their meat products within the business and before selling because the product will attract better prices than relatively unprocessed meat. • The tenderness of breast meat was found to be significantly influenced by the dietary treatment.

Significantly higher L* value and cooking yield (P < 0.05) were seen in the samples of TA and WIC than those of no TA and HB-1/4CFAC, respectively, with no difference observed between COMM and RB fillets (P > 0.05).

In summary, these findings revealed that mixed MG can be used as an effective and novel feed supplement to improve productive performance and quality of broilers. Since 1970s, such meat quality, problems have been reported in turkeys and broilers with a. prevalence ranging between 5 and 40% (Owens et al. DNA or recombinant DNA to tissues has been proven yet. Nevertheless, several crucial pathways (e.g., adipocytokine signaling, AGE-RAGE signaling, and apoptosis) and genes (e.g., ANO6, ACER2, UCP3, DTL, and TMEM120A) were tightly related to the muscle group–specific adaptive remodeling on different raising systems. /op false Meat colour was expressed by tristim spectral coordinates L*, a*, b* colour space in CIEL* a* b* (AMSA). completion of rigor varies with species, muscle, fiber type, holding temperature, rate of glycolysis and the extent of, struggling at the time of death.

Consumers, with increasing health consciousness, are becoming more aware of the nutritional value of the, foods they eat. From this perspective, the aim of our work was to study the effect of pre-slaughter handlings on broiler chicken’s welfare and relationship with meat quality. water loss, by stimulating thermo-oxidation reactions, changing the color of the product to brown and by modi-. Drip loss (24 h) in the breast muscle of the tryptophan treatment was the highest (P < 0.05), followed by that of β-glucan (P > 0.05), then 3.5%OD, VE diet, 7%OD, and the control (P < 0.05). The Quality of Nugget of Broiler Chicken Meat with Addition of Sago Flour (Metroxylon Sp.) (lyophilization) is a drying process in which the solvent, and/or the suspension medium is crystallized at a low, temperature and thereafter sublimated from the solid state. Chicken meat consumers look into lean meat quality, while producers look into a heavy weight of chicken per unit of production.
