Thigh meat from Cobb 500 broiler (Cobb) and Beijing-You chicken (BYC) at marketable age were compared to explore the impact of growth rate on quality. BYC had a higher water capacity, as well lower shear forces IMF content than Cobb, indicating that has significant influence Additionally, 144 upregulated 44 downregulated differential metabolites identified using gas chromatography mass spectroscopy (GC-MS) liquid spectrometer (LC-MS). Moreover, we found difference between dominant expression...
Copy number variation (CNV) is an important genetic mechanism that drives evolution and generates new phenotypic variations. To explore the impact of CNV on chicken domestication breed shaping, whole-genome CNVs were detected via multiple methods. Using sequencing data from 51 individuals, corresponding to six domestic breeds wild red jungle fowl (RJF), we determined 19,329 duplications 98,736 deletions, which covered 11,123 copy regions (CNVRs) 2,636 protein-coding genes. The principal...
Poultry welfare has been extensively studied; however, there is a lack of rigorous scientific knowledge relating to the different aspects factors and how this may contribute production quantity product quality as well chickens. Therefore, we conducted an integrated study compare in chickens by providing free dietary choice under cage rearing, further comparing rearing with free-range rearing. One hundred each were allocated group conventional feeding (CC), mealworms (FDM), fresh grass...
This study aimed to investigate the effects of dietary crude protein (CP) and lysine levels on growth performance, slaughter meat quality, myofiber characteristics slow-growing chicken. A 3 × factorial experiment was arranged, chickens were fed with CP (16.0%, 17.0%, 18.0%) (0.69%, 0.84%, 0.99%). total 540 8-week-old Beijing-You Chicken (BYC) female growing randomly allocated 9 groups, 5 replicates per group, 12 replicate. The birds one experimental diets. Growth determined at 16 weeks age....
Unique metabolites contribute to the performance of meat flavor and potential function. In this study, UHPLC-Q Exactive HF-X-based metabolomics multivariate analysis were applied explore characteristic in breast Beijing-You chicken (BYC) aged 150, 300, 450 days (D150, D300, D450). Based on criteria variable importance projection (VIP) > 1
The disparity in fatty acids (FA) composition exhibits a significant impact on meat quality, however, the molecular regulatory mechanisms underlying this trait chicken are far from clear. In study, total of 45 female Beijing-You (BYC) hens, fed same diet, were collected at slaughter age 150, 300, or 450 days (D150, D300, and D450) sexual maturation stage to culling (15 birds per age). Gas chromatography-mass spectrometry (GC-MS) tandem mass tag labeling technology based liquid chromatography...
Chicken age contributes to the meat characteristics; however, knowledge regarding pathways and proteins associated with quality muscle development are still scarce, especially in chicken thigh meat. Hence, objective of this study was elucidate intricate relationship between these traits by liquid chromatography mass spectrometry at three different ages. A total 341 differential expressed (DEPs) were screened out (fold change ≥ 1.50 or ≤0.67 p < 0.05) among 45 samples (15 per age) Beijing-You...
Chronological age is one of the important factors influencing muscle development and meat quality in chickens. To evaluate protein expression profiles during skeletal development, we performed a tandem mass tag (TMT)-based quantitative proteomic strategy pectoralis major (breast muscle) Beijing-You chicken (BYC) at chronological 90, 120, 150 days. Each contained 3 pooling samples or 15 birds (five per sample). A total 1,413 proteins were identified breast with FDR &lt; 1% 197 them...
Abstract The molecular regulatory mechanism underlying meat quality between different chicken genotypes remains elusive. This study aimed to identify the differences in metabolites and pathways pectoralis major (breast muscle) a commercial fast‐growing genotype (Cobb500) slow‐growing Chinese native (Beijing‐You chickens, BYC) at market ages respectively based on ultra‐high‐performance liquid chromatography‐quadrupole/time of flight mass spectrometry (UHPLC‐QTOF/MS). Eighteen were identified...
The physical properties, free amino acids, and metabolites of Beijing-You chicken (BYC) breast meat aged 90, 120, 150 days were analyzed to investigate the flavor changes with age. shear force intramuscular fat increased from 90 120 significantly. contents total acids essential decreased No significant differences detected between days. sweet bitter umami showed no different ages. In addition, GC-MS LC-MS integrated for metabolite detection in meat. A 128, 142, 88 differential identified...
Farm animals raised under free-range (FR) systems are assumed to have improved welfare and higher-quality products that better eat than intensively reared animals. However, the modulations limited in scientific investigations. In this study, we compared 2 rearing (FR cage) their effects on chickens, including production performance, product quality, body condition, physiological indicators, gene expression. By using a match-mismatch design which each treatment was transferred other during...
The Beijing You chicken is a Chinese native breed with superior meat quality and unique appearance. G/T mutation of SNP rs80659072 in the Shh long-range regulator GGA2 highly associated polydactyly phenotype some breeds. In present study, this was genotyped using TaqMan detection method, its association number toes analyzed flock 158 birds population maintained at Academy Agriculture Forestry Sciences. Furthermore, skeletal structure digits dissected assembled 113 birds. findings revealed...
Lipopolysaccharide (LPS) is ubiquitous in the environment and released after death of gram-negative bacteria, which may be related to inflammation immunosuppression. However, its impact on reproduction animals their offspring, especially underlying mechanism need further elucidation. Here, we used laying hens as a model organism investigate effects maternal exposure LPS (LPS stimulation) animal offspring's immunity reproductive performance, well regulatory role transcriptome. We found that...
By a semi-discrete tamed Euler approximation as bridge, this paper examines the scheme for Mckean-Vlasov stochastic differential equations (SDEs) and obtains convergence rate under one-sided Lipschitz condition drift coefficient. Under local coefficient, strong of is also examined. When coefficients satisfy condition, asymptotic error distribution.
As the only two You-chicken breeds in China, Baicheng-You (BCY) and Beijing-You (BJY) chickens are famous for their good meat quality. However, so far, molecular basis of germplasm is not yet clear. The genetic relationship among BCY, BJY, European-origin broilers (BRs) was analyzed using whole genome resequencing data to contribute this issue. A total 18,852,372 single nucleotide polymorphisms (SNPs) were obtained study. After quality control, 8,207,242 SNPs applied subsequent analysis....
In this study, using a newly developed TaqMan-based real-time PCR method for the T329S mutation in flavin-containing monooxygenase 3 (FMO3) gene, marker-assisted selective breeding program against unfavorable T allele was implemented Beijing You chicken stock from 2010 to 2012. A total of 2,359 breeder candidate chickens were detected.
