“…Moreover, to the best of our knowledge, there are no studies that measure catecholamine metabolites in bovine meat or biological fluids in relation to DC. However, adrenaline and noradrenaline have been measured in cattle urine in studies looking at the effects of preslaughter stress and meat quality (Bourguet et al, 2015;Reiche et al, 2019). Bourguet et al found no correlations between urinary levels of stress hormones and postmortem pH decline of young bulls from different breeds undergoing the same slaughter procedure.…”

Meat quality can be affected by stress, exhaustion, feed composition, and other physical and environmental conditions. These stressors can alter the pH in postmortem muscle, leading to high pH and low‐quality dark cutting (DC) beef, resulting in considerable economic loss. Moreover, the dark cutting prediction may equally provide a measure for animal welfare since it is directly related to animal stress. There are two needs to advance on‐site detection of dark cutters: (1) a clear indication that biomarker (signature compounds) levels in cattle correlate with stress and DC outcome; and (2) measuring these biomarkers rapidly and accurately on‐farm or the abattoir, depending on the objectives. This critical review assesses which small molecules and proteins have been identified as potential biomarkers of stress and dark cutting in cattle. We discuss the potential of promising small molecule biomarkers, including catecholamine/cortisol metabolites, lactate, succinate, inosine, glucose, and β‐hydroxybutyrate, and we identify a clear research gap for proteomic biomarker discovery in live cattle. We also explore the potential of chemical‐sensing and biosensing technologies, including direct electrochemical detection improved through nanotechnology (e.g., carbon and gold nanostructures), surface‐enhanced Raman spectroscopy in combination with chemometrics, and commercial hand‐held devices for small molecule detection. No current strategy exists to rapidly detect predictive meat quality biomarkers due to the need to further validate biomarkers and the fact that different biosensor types are needed to optimally detect different molecules. Nonetheless, several biomarker/biosensor combinations reported herein show excellent potential to enable the measurement of DC potential in live cattle.

“…These samples collected from the sampling process were kept in the refrigerator at 4℃ for 24hours (D1), D7 and D14, respectively. After the designated periods were completed, the samples were removed from the polyethylene bags, gently blotted dry and weighed [43]. The drip loss was calculated as the percentage of differences between the initial and final weight.…”

“…Rejections occur at the purchasing point when the meats do not meet the standard water holding capacity (WHC) [43], which is a complex attribute of meat [44]. In general, factors that affect WHC are either pre/post-slaughter [40], such as genetics and production system, or other processing factors during the meat production chain [16].…”

Water holding capacity of Swamp Buffalo muscles raised with and without proper herd health

et al. 2021

Fresh meat is composed of 70-75% water. Meanwhile, water holding capacity (WHC) affects storage quality, appearance, eating experience, and also contributes to loss of profit for meat entrepreneurs. WHC is influenced by the species, sex, breed, farming practices, as well as post-slaughter storage and handling. Swamp buffalo meat is leaner compared to cattle, goats, and sheep. Therefore, this study aims to determine the WHC of swamp buffalo muscles raised with two herd health programs at different aging periods. A total of 24 months old male swamp buffalo (n=4) was raised with a proper herd health protocol (HHP) and another (n=6) without a proper herd health protocol (NHHP). The drip loss (DL), thawing loss (TL), and cooking loss (CL) for longissimus dorsi (LD), supraspinatus (SS), and semitendinosus (ST) muscles were evaluated on day 1, 7, and 14. Based on the results, only SS and ST from NHHP showed significant differences (P≤0.05), while DL, LD, SS, and ST of the HHP and NHHP also differed significantly (P≤0.05). Furthermore, the TL and CL for all the muscles showed significant differences (P≤0.05) at day 7 of aging in the NHHP group, while on day 14, both were significantly higher in LD and ST muscles of NHHP compared to the HHP group. Therefore, the results showed that the muscles of the HHP group had a better WHC compared to NHHP.

“…Most of the above conditions often occur during farm management, during preslaughter operations ( Deters & Hansen, 2020 ) or during slaughter, and they have detrimental effects on nutritional and organoleptic meat quality, as reported in pigs and poultry ( Debut et al, 2005 ; Debut et al, 2003 ; Monin & Sellier, 1985 ). There is also compelling evidence that preslaughter stress has an undesirable effect on meat quality traits ( e.g ., low tenderness and juiciness) in both beef and lamb ( Ferguson & Warner, 2008 ; Muchenje et al, 2009 ; Terlouw, 2015 ; Terlouw et al, 2008 ; Terlouw et al, 2021 ; Reiche et al, 2019 ). The impact of stress on meat quality has been explained by changes in physiological and metabolic properties of the muscle, which is converted to meat postmortem : higher depletion of glycogen before slaughter, less production of lactic acid (a byproduct of post-mortem glycolysis), and thus insufficient pH decline.…”

In meat-producing animals, preslaughter operations (e.g., transportation, mixing unfamiliar animals, food and water deprivation) may be a source of stress with detrimental effects on meat quality. The objective of this work was to study the effect of emotional and physical stress by comparing the transcriptomes of two muscles (M. longissimus thoracis, LT and M. semitendinosus, ST) in Normand cows exposed to stress (n = 16) vs. cows handled with limited stress (n = 16). Using a microarray, we showed that exposure to stress resulted in differentially expressed genes (DEGs) in both muscles (62 DEGs in LT and 32 DEGs in ST, of which eight were common transcription factors (TFs)). Promoter analysis of the DEGs showed that 25 cis transcriptional modules were overrepresented, of which nine were detected in both muscles. Molecular interaction networks of the DEGs targeted by the most represented cis modules helped identify common regulators and common targets involved in the response to stress. They provided elements showing that the transcriptional response to stress is likely to (i) be controlled by regulators of energy metabolism, factors involved in the response to hypoxia, and inflammatory cytokines; and (ii) initiate metabolic processes, angiogenesis, corticosteroid response, immune system processes, and satellite cell activation/quiescence. The results of this study demonstrate that exposure to stress induced a core response to stress in both muscles, including changes in the expression of TFs. These factors could relay the physiological adaptive response of cattle muscles to cope with emotional and physical stress. The study provides information to further understand the consequences of these molecular processes on meat quality and find strategies to attenuate them.
