“…In fact, a negative correlation between breast muscle weight and glycogen stored in the muscle, i.e., a positive correlation of breast weight with the final pH, has been reported (Le Bihan-Duval et al, 2008). While we measured a higher shear force for cutting meat of male chickens, other authors found a lower value than female chickens which was attributed to the smaller fiber diameter in males (Cygan-Szczegielniak and Bogucka, 2021).…”

Fast-growing broiler chickens are subjected to breast myopathies such as white striping (WS), wooden breast (WB), and spaghetti meat (SM). Available studies about risk factors for myopathy occurrence often used flock data whereas a few reports evaluated chicken individual data. Thus, the present study aimed to elucidate the effect of growth and slaughter traits, besides sex and genotype on myopathy occurrence. Data were obtained from eight experimental trials, which used a total of 6,036 broiler chickens. Sex, genotype, daily weight gain, slaughter weight, and breast yield were evaluated as potential risk factors by logistic regression analyses. Then, the effects of myopathy and sex were evaluated on meat rheological traits (pH, colour, cooking losses and shear force). Based on a logistic regression, WS occurrence was associated with genotype, breast weight, and breast yield. Compared with chickens with intermediate breast weight and breast yield, higher odds of having WS were found in chickens with high breast weight (OR: 1.49) and yield (OR: 1.27), whereas lower odds were found in those with low breast weight (OR: 0.57) and yield (OR: 0.82). As for WB and SM, females had lower odds of having WB (OR: 0.55) and higher odds of showing SM (OR: 15.4) compared to males. In males, higher odds of having WB were found in chickens with a high daily weight gain (OR: 1.75) compared to those with an intermediate daily weight gain. In females, higher odds of having SM were associated to a high slaughter weight (OR: 2.10) while lower odds to a low slaughter weight (OR: 0.87). As for meat quality, only WB meat was clearly different for some technological and sensorial properties, which can play a major role also in meat processing. In conclusion, our analysis identified breast development as a potential risk factor for WS, while a high growth was the risk factor for WB and SM. A different probability of having WB or SM in females and male was found.

“…In our study, the higher final body weight of SP-treated chicks was not accompanied by a higher carcass percentage of the chickens. In general, the disparity results about the carcass percentage have been attributed to variances in chicken types (modern broiler versus native or crossbred chickens), age, sex, physical activity and environmental condition of chickens (Li et al 2017;Cygan-Szczegielniak and Bogucka 2021).…”

Combined use of Spirulina platensis and Saccharomyces cerevisiae: Implication on growth, blood profile and intestinal morphology and bacteria of the Indonesian crossbred chickens

Abstract. Sugiharto S, Atmaja BM, Widiastuti E, Hadiyanto H. 2021. Combined use of Spirulina platensis and Saccharomyces cerevisiae: Implication on growth, blood profile and intestinal morphology and bacteria of the Indonesian crossbred chickens. Biodiversitas 23: 160-165. The effects of Spirulina platensis and Saccharomyces cerevisiae on poultry growth and health have long been known. However, no research has been conducted on the combined use of these substances on the Indonesian crossbred chicken (ICC). This study evaluated how the combined use of S. platensis and S. cerevisiae affected ICC growth, blood profile, and intestinal ecology. A total of 288 ICC were separated into three groups, including CONT (basic diet), SP (diet with 0.3% S. platensis), and SPSC (diet with 0.3% S. platensis and 0.2% S. cerevisiae). Blood and intestinal content and segments were taken at week 9, while growth was determined weekly. SP had greater (p<0.05) body weight than CONT, but did not differ from SPSC. In SP, ileal coliform counts were lower (p=0.07) than in CONT. SPSC had lower (p=0.07) caecal Enterobacteriaceae counts than other groups. Blood profile, intestinal morphology, organ weight, and carcass traits did not vary (p>0.05) across the ICC. In conclusion, dietary supplementation of S. platensis improved growth performance and bacterial population of the ICC.

“…The chemical composition of chicken meat is closely related to breeding, which means that genetics is the main influencing factor [ 1 , 17 , 18 ]. In this study, we found large moisture difference between breast muscle and thigh muscle, but not genders.…”

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.
