Meat and fish serve as important protein sources in the companion animal diet; however, limited protein digestibility data are available for assessing protein digestibility differences among good-quality protein sources. Beef loin, pork loin, chicken breast, pollock fillet, and salmon fillet were evaluated for composition, protein digestibility, and AA bioavailability using the immobilized dige...

BACKGROUND Chicken meat has the highest per capita consumption among all meat types in North America. The practice of feeding 3-nitro-4-hydroxyphenylarsonic acid (Roxarsone, Rox) to chickens lasted for more than 60 years. However, the fate of Rox and arsenic metabolites remaining in chicken are poorly understood. OBJECTIVES We aimed to determine the elimination of Rox and metabolites from chi...

This study aims to determine the polymorphism and mRNA expression pattern of the heart-type fatty acid-binding protein (H-FABP) gene and their association with intramuscular fat (IMF) content in the breast and leg muscles of Baicheng oil chicken (BOC). A total of 720 chickens, including 240 black Baicheng oil chicken (BBOC), 240 silky Baicheng oil chicken (SBOC), and 240 white Baicheng oil chic...

The ability of pure cultures of bacteria isolated from spoiling chicken breast muscle to produce strong off-odors was tested by using sterile breast muscle sections. The incidence of organisms capable of producing strong off-odors and changes in flora during storage of naturally spoiling muscle at 2 C was traced, and the relationship between bacterial type and off-odor production was noted.

Aqueous chlorine dioxide (ClO2) treatment was used for the inactivation of Listeria monocytogenes and Campylobacter jejuni in chicken. Chicken breasts and legs were inoculated with 8~9 log CFU/g of Listeria monocytogenes and Campylobacter jejuni, respectively, and then treated with 0, 50, and 100 ppm of ClO2 solution. Aqueous ClO2 treatment decreased the populations of the pathogenic bacteria o...

Glycogen phosphorylase b has been purified from chicken breast muscle to a state of homogeneity as judged by the criteria of polyacrylamide gel electrophoresis and ultracentrifugal analysis. The absorbance index A I$ nm was found to be 13.2, the sedimentation coefficient s~(,,~. was 8.7, at a concentration of 2.5 mglml, the subunit molecular weight was 100,000, and the molecular weight of the n...

Growth hormone (GH) plays a diverse role in animals together with other hormones of somatotropic axis. In the current research, chicken GH (cGH) as a candidate gene affecting carcass traits was investigated in the chickens from 2 local chicken breeds [Mountainous Black-Bone (Wugu) and Caoke chicken] in the Sichuan province, 1 pure line of a quality chicken (Sanhuang chicken) from the Guangdong ...

The objective of this examination is to decide the predominance Campylobacter spp. in some chicken cuts and giblets items by utilizing both ordinary sub-atomic techniques. zoontic spp.widelyhus,120 item tests (25g each) were gathered from different general stores at Menofia legislature breast, thigh, liver gizzard. Most examples defiled with species demonstrated most elevated pollution (56.67%)...

This study was performed to investigate the changes in meat quality characteristics of the sous vide cooked chicken breast during refrigerated storage at 4℃ for 14 d between before and after sous-vide cooking. Cooking loss and shear force were significantly increased, whereas expressible drip was significantly decreased along with reduction in the water holding capacity in both of two groups. R...
