To investigate the effects of early administration of ciprofloxacin (CIP) on Xueshan chickens, in this study Xueshan chickens were measured for growth performance, tested for drug residues, evaluated for meat quality, and muscle metabolism changes were explored using a non-target metabolomics approach. Experimental findings revealed that early CIP use did not significantly impact the overall growth rate of Xueshan chickens ( > 0.05). However, notable alterations in meat quality were observed: the CIP-treated group exhibited a significant decrease in muscle pH (pH and pH) and a marked increase in drip loss and moisture content ( > 0.05). No CIP residues were detected in muscle tissue. Untargeted metabolomics analyses unveiled significant alterations in the metabolic profile of market-age chickens following CIP treatment. Both functional enrichment and metabolic network analyses indicated significant effects on the ko01120 (microbial metabolism in diverse environments) and ko00350 (tyrosine metabolism) pathways, implying that CIP treatment may influence chicken meat quality by modulating microbial communities and amino acid metabolism. This study provides a crucial foundation for understanding the impact of antibiotics on meat quality and metabolism in poultry production, offering scientific insights for optimizing antibiotic-use strategies and safeguarding poultry product quality.

Introduction: Frozen pork can reduce the quality of the meat and alter the digestibility and bioavailability of meat proteins in the human body. In this study, we investigated the changes in the basic composition during frozen storage and their effects on the structural properties of digestion products after protein digestion.
Methods: The impacts of frozen storage at different temperatures (-8, -18, -25, and -40°C) and for different times (1, 3, 6, 9, and 12 months) on the basic components and digestive characteristics of pork were evaluated.

Background: Meat is a good source of protein in the human diet, and more than three-quarters of the world's population consumes it. It is the most perishable food item since it has enough nutrients to enable microbial growth. In underdeveloped nations, animals are routinely slaughtered and sold in unsanitary conditions, compromising the bacteriological quality and safety of the meat received from the animals.

Introduction: Non-typhoidal (NTS) are leading bacterial agents of foodborne illnesses and a global concern for human health. While there are over 2,600 different serovars of NTS, epidemiological data suggests that certain serovars are better at causing disease than others, resulting in the majority of reported human illnesses in the United States. To improve food safety, there is a need to rapidly detect these more pathogenic serovars to facilitate their removal from the food supply.

Apoptosis serves as the initial phase in the conversion of muscle to meat, driving key biochemical and morphological changes in the postmortem muscle. To effectively improve and control meat quality across different animal species, it is important to gather more information on the mechanisms by which apoptotic potential, mediated through the interaction of apoptosis-related molecules, influences meat quality variations. The apoptotic potential, determined by the balance between apoptotic and anti-apoptotic molecules, such as Ca, cytochrome , caspases, and heat shock proteins, varies among different species.

This study aimed to evaluate the effects of dietary inulin (0-30 g/kg) on duck meat, muscle fiber types, meat quality, antioxidant ability, Low-field nuclear magnetic resonance, amino acid and off-flavor. These results indicated that inulin promoted the conversion of type II to type I muscle fibers. Compared with the control group, supplementation with 20 g/kg inulin reduced ( < 0.
