Drip loss is an indicator of water holding capacity in fresh meat that can be measured using the bag method and the newer EZ method. However, to our knowledge, no previous study has investigated the application of these methods to assess drip loss of fresh alpaca meat. Over a year, 160 alpaca (Vicugna pacos) loins were sampled using the two different drip loss methods. There was no difference (P = 0.490) in drip loss percentage between the bag (3.39 ± 0.24%) and EZ method (3.16 ± 0.22%). The 24 h pH had a significant (P = 0.03) impact on drip loss percentages, such that as pH increased the drip loss percentage decreased. A greater (P < 0.001) drip loss was found using the bag method if the sample weighed 80 g (4.04 ± 0.15%) compared to 60 g (3.38 ± 0.12%).

Previously, animal breeding prioritized enhancing key economic traits to improve production efficiency, leading to a gradual difference in meat quality. However, the genetic factors influencing meat quality remain unclear. To identify key genetic pathways contributing to meat quality, native Chinese yellow-feathered chicken (Qingyuan Partridge Chicken, QPC; female, n=10), and commercial chicken broiler (Cobb broiler, CB; female, n=10) were used for meat quality assessment through metabolomics, proteomics, and phosphoproteomics sequencing.

Meat rabbits are a small herbivorous livestock and have been popularly raised in China for producing high-quality meat. Therefore, it is economically important to genetically improve both carcass performance and meat quality in meat rabbits. However, we still know less about the underlying candidate genes that may determine phenotypic variation on carcass and meat traits of meat rabbits.

The objective of this experiment was to evaluate the physiochemical characteristics of three tertiary hybrids (crossbreeds) of pigs, with and without coffee supplementation. A total of fifty pigs of different mixed breeds Landrace × Yorkshire × Duroc (LYD), Yorkshire × Berkshire (YB), and Yorkshire × Woori (YW); 113.45 kg ± 3.

This study assessed the meat quality of Sika deer () from various age and sex groups using the longissimus dorsi (LD) muscle. Samples from different age groups (2, 3, and 4 years old) were analyzed for various parameters. The results show that, with increasing age, there is a decrease in moisture and drip loss ( < 0.

To elucidate the mechanisms of ozone gas (OG) and slight acid electrolyzed water (SA) on the quality changes in texture, water-holding capacity, and softening of salmon, the bacterial growth, total volatile basic nitrogen, thiobarbituric acid reactive substance, a* value, texture properties, carbonyl content and free sulfhydryl content, myofibrillar fragmentation index, and proteolytic activities of salmon treated by OG (1 mg/m for 10 min) and SA (ACC 30 mg/L, 5 min) individually and in combination were studied. The results showed that total viable counts of SA + OG (dipped in SAEW for 5 min, followed by exposure to ozone for 10 min) was about 3.36 log CFU/g lower than the control (CK) (dipped in distilled water for 5 min) on day 10.
