“…Sex differences are associated with growth performance in chickens [ 9 ], and genetic studies have reported that muscle characteristics, such as fiber CSA, have high heritability (>0.40) and exhibit significant positive genetic correlations with body and muscle weights in broilers between 4 and 6 weeks [ 13 ]. Moreover, muscle morphology is affected by many factors, such as breed [ 14 ], muscle type [ 10 ], age [ 11 , 13 , 15 ], and gene polymorphism [ 11 ]. In the present study, the muscle morphological characteristics of the breast and thigh muscles were assessed at different developmental stages, and the CSA of the breast and thigh muscles increased with age.…”

“…The ultimate goal is to provide high levels of growth performance and quality of their meat. The development and composition of breast and thigh muscles, as the main meat-producing parts of chickens, are affected by breed [ 6 ], sex [ 7 ], nutrition [ 8 ], intestinal microbial species [ 9 ], and rearing systems [ 10 ]. Chicken is a favorite food product for healthy eating because it contains higher levels of protein as well as lower fat content than other meats.…”

This study was conducted to illustrate the morphological features of the breast and thigh muscles at four developmental stages (1, 42, 84, and 126 days of age) of Wuliangshan Black-bone chickens and to compare the chemical composition, fatty acid, and amino acid contents of their meat at 126 days of age (D126). In total, 80 chickens (male, n = 40 and female, n = 40) in the sixth generation from the breeding farm were used in the experiment under free-range rearing conditions. The cross-sectional areas (CSA) of muscle fibers and meat composition were compared between different sex and different muscle types. The results showed that gender did not affect the CSA of the breast muscle fibers but did affect the CSA of the thigh muscle fibers at D42, D84, and D126 (p < 0.05). Muscle types affected the CSA of muscle fibers: male chickens exhibited significantly higher values than female chickens at D42, D84, and D126 (p < 0.05). The results of moisture, crude protein, and crude fat at D126 showed that moisture contents were higher in the thigh muscles than in the breast muscles in male and female chickens (p < 0.05). Gender affected the crude protein contents and crude fat contents: the breast muscle crude protein content was significantly higher than that in the thigh muscle, both in males and females (p < 0.05), whereas the crude fat contents were significantly higher in females than in males (p < 0.05); moreover, the thigh muscle fat contents were significantly higher than those of the breast muscles both in males and females (p < 0.05). Gender and muscle types also affected the fatty acid contents: the PUFA contents of the breast and thigh muscles were significantly higher in male than in female chickens (p < 0.05). Muscle types significantly influenced the total EAA, NEAA, and flavor amino acid contents. The total EAA contents of the breast muscles were significantly higher than those of the thigh muscles in males and females (p < 0.05), whereas the total NEAA and total flavor amino acid contents of the thigh muscles were significantly higher than those of the breast muscles (p < 0.05). Our results may lead to a better understanding of the effects of gender on the breast and thigh muscle development and meat composition of Wuliangshan Black-bone chicken.

“…With the increase of pigeon age, the moisture content gradually decreased, while the fat content showed a bell‐shaped curve, and reached the maximum value at 28 days. The edible and nutritional value of animal meat was related to protein, fat, and water content, which were closely related to tenderness and juiciness of meat (Guo et al, 2020). Thus, 28‐day‐old pigeons were richer in fat and water content.…”

Pigeon soup is one of the traditional Chinese soups, but effects of pigeon breeds and pigeon ages on the nutrition and flavor of soup remain unclear. The objective of this study was to evaluate the differences of nutritional components in different breeds (Liangtian king pigeon, American ground king pigeon, Dabao pigeon, and Shiqi pigeon) and different ages (18 days, 28 days, 4 years) of meat pigeons. Meanwhile, the differences of volatile flavor substances in pigeon soups were further explored by GC–MS and GC‐IMS. The result showed that the crude fat content of Liangtian king pigeon was significantly higher than that of the other three breeds. Besides, the water content of Liangtian king pigeon was markedly higher than that of American ground king pigeon. Meantime, with the increase of pigeon age, the content of crude fat of 28‐day‐old pigeon was considerably higher than that of 4‐year‐old pigeon. Additionally, the results of GC–MS and GC‐IMS indicated that the varieties and contents of volatile flavor substances in Liangtian king pigeon soup were more abundant, with a total content of 815.41 μg/L. Moreover, the volatile flavor substances in 28‐day‐old pigeon soup were higher, with a total content of 815.39 μg/L. Overall, the 28‐day‐old Liangtian king pigeon was an optimal raw material for soup. The result of this study might provide a reference for the selection of pigeon soup materials, improving the quality and flavor of pigeon soup. In addition, it laid a theoretical foundation for revealing the potential health and nutrition value of pigeon soup and promoting its industrialization. Novelty impact statement The results of nutrient composition analysis showed that water, crude fat, and fatty acid contents of 28‐day‐old Liangtian king pigeons were higher than American ground king pigeon, Dabao pigeon, and Shiqi pigeon. SPME‐GC–MS and GC‐IMS showed that the volatile flavor compounds in 28‐day‐old Liangtian king pigeon soups were 815.39 μg/L, so 28‐day‐old Liangtian king pigeons were recommended for soup. This study provided scientific basis for Cantonese soup industrialization development.

“…Usually, muscle ber types are de ned by the isoforms of myosin heavy chain (MHC) as MyHC I, IIa, IIb, and IIx, based on their different ATPase types [10]. The gene expression related to the intramuscular fat metabolism, such as PPARγ, CPT1,SREBP1, etc., was affected by rearing systems [11]. Different rearing environments may also impact the lipid, protein, and energy metabolism in skeletal muscle by modulating the mechanistic target of the rapamycin (mTOR) signaling pathway [12].…”

Background: The objective of this experiment was to investigate the influence of early exposure to topsoil on the muscle fiber characteristics and transcription related myogenesis, intramuscular fat metabolism, muscle fiber types, and mTOR signaling pathway of weaned pigs.Methods: A Total of 180 piglets were separately assigned to No soil, Antibacterial soil, and Normal soil group (each group, n=60), and were fed ad libitum with common antibiotic-free corn-soybean meal diets until day-31. Ten pigs from each group with similar body weight were selected to be slaughtered, and the longissimus dorsi (LD) muscle samples were collected for histological analysis and measurements of genes and proteins expression levels.Result: In the present study, the muscle fiber diameter and the area of Normal soil and Antibacterial soil group were significantly higher than No soil group (P < 0.05). The Normal soil significantly upregulated the gene expression of MyoG compared to No soil and Antibacterial soil groups (P < 0.05). The gene expression of CD36 and CPT-1 of Normal soil group was significantly lower than No soil group (P < 0.05), while HSL expression of Normal soil group was significantly higher than Antibacterial and No soil groups (P < 0.05). The MyHC I of Normal soil group was significantly higher than No soil group (P < 0.05), but the expression MyHC IIa was lower than No soil group (P < 0.05). The protein expression expressed the similar result with gene expression. In addition, the Normal soil significantly increased the AMPK and mTOR phosphorylation compared to No soil and Antibacterial soil groups (P < 0.05).Conclusion: These data suggest that early exposure to topsoil regulates the muscle fiber growth, modulates the expression pattern related to myogenesis, muscle fiber type, intramuscular fat metabolism, and increases the phosphorylation of mTOR and AMPK pathways.
