Quality Characterization of Different Parts of Broiler and Ligor Hybrid Chickens

Abstract

The quality characterization of different parts of male and female Ligor hybrid chickens was investigated and compared with those of commercial broiler. Genotypes, muscle types, and sex had effects on the composition, physicochemical, and textural properties of chicken samples. Ligor hybrid chicken contained higher percentages of protein, moisture, ash, and collagen content but lower fat content than those of commercial broiler (p < 0.05), except in the case of breast, where no significant difference in moisture and ash was observed (p ≥ 0.05). The pH in breast meat of both chickens was lower than that of thigh meat. The color (L*, a*, and b*) values of male and female chickens were not significantly different, except for the L* value of broiler chicken, which was higher in female chickens than in male chickens. Higher cooking loss and shear force were found in male Ligor hybrid chicken. A similar protein pattern was observed for the protein from the same muscle type, irrespective of sex and genotype tested. It was observed that Ligor hybrid chicken contained higher glutamic acid and aspartic acid than commercial broilers. Therefore, Ligor hybrid chicken is a promising new source of nutrition, which can be beneficial for consumers.

Nutrition and Flavor Evaluation of Amino Acids in Guangyuan Grey Chicken of Different Ages, Genders and Meat Cuts

“…As observed in the results, the content of crude protein was higher in the pectoral than thigh muscle ( p < 0.05). This was compatible with previous research [ 26 , 27 ]. It indicates that the protein nutritional value of the pectoral muscle is higher than that of the thigh muscle.…”

“…We found that the thigh muscle had a higher moisture and CF than those of the pectoral muscle in all age groups, and this result was more pronounced in the case of female chickens. These results were also observed in Panpipat’s study, while there was no difference between the genders in their study [ 26 ]. Thus, the thigh muscle may have a better texture than the pectoralis of Guangyuan grey chicken.…”

Data Mining as a Tool to Infer Chicken Carcass and Meat Cut Quality from Autochthonous Genotypes

“…Within the gross nutrient cluster, protein presented the highest discriminant potential. Indigenous chickens have been reported to usually present progressively higher protein levels as they age [ 177 ]. In this way, the high variability in the slaughter age variable also caused the protein content to vary across the genotypes that were sampled in this study.…”

“…In this way, the high variability in the slaughter age variable also caused the protein content to vary across the genotypes that were sampled in this study. Nevertheless, the conditioning effects of other factors such as genotype and sex on protein content cannot be discarded, as suggested by the literature [ 177 , 178 ].…”

Sex differences in <i>COL1A1</i> Expression and Collagen Content in Skeletal Muscle of Mature and Juvenile Shamo Chickens

“…The ITL muscle in hens has lower collagen content than Silky and White Leghorn cockerels. In broiler chickens, collagen content in the thigh muscle is higher in males than in females, but not in the breast muscle at 14 weeks of age[ 10 ]. Considering such differences, it may be useful to examine the difference in gene expression levels of collagen and related stimulating factors to clarify them, but few studies to date have done so.…”
