“…After drip loss measurement, the same meat samples were placed in a plastic freezer bag and frozen at −20 • C. Afterwards, the samples were thawed at room temperature for 12-16 h and then taken from the bag, gently blotted dry with tissue paper, and re-weighed. Differences of weights gave the thawing loss of the samples [28]. The thawed samples were put in a plastic (Ziploc) bag and then placed in a continuously boiling water bath until the internal temperature reached 75 • C, which was measured using a thermometer with a hand probe (Testo 110, Testo AG, Lenzkirch, Germany) [33].…”

“…The increase in APP levels, such as pig major acute-phase protein (Pig-MAP), haptoglobin, C-reactive protein (CRP), and serum amyloid A (SAA), have been observed after long and short transportation, as well as following isolation and changes in the food administration pattern [23][24][25][26]. However, only a few published papers have investigated the relationships between increased APPs and lower meat quality in terms of meat acidification and water holding capacity [27][28][29].…”

“…Non-invasive, quick, accurate, and reliable on-site prediction of pork quality would facilitate the distribution of whole carcasses or carcass cuts for fresh pork, different processing sectors (dry-cured ham or sausage production), or for meat branding (e.g., premium meat, meat products with protection of geographical indications, protected designations of origin, and guaranteed traditional specialty) according to their intrinsic characteristics and potential quality value. To date, several studies [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] have investigated physiological stress biomarkers as potential predictors of meat quality, as indicated previously. However, the high inconsistency of results reflects the complexity of meat quality traits, which are affected by multiple interacting factors, including genetic background, breeding, environmental factors, preslaughter conditions, as well as slaughtering procedures.…”

This study assessed the potential use of various physiological stress biomarkers as indicators of carcass and meat quality traits in 240 pigs subjected to the standard marketing conditions and minimal stressful antemortem handling using Pearson correlations. The most important pork quality traits (pH and temperature, water holding capacity, and color) had limited correlations with stress metabolites (lactate, glucose), stress hormones (cortisol, adrenocorticotropic hormone), stress enzymes (creatine kinase, aspartate amino transferase, alanine amino transferase), electrolytes (sodium, chloride), and acute-phase proteins (haptoglobin, C-reactive protein, albumin), indicating poor reliability in predicting pork quality. Albumin level was moderately positively correlated with live weight, hot carcass weight, cold carcass weight, and back fat thickness. Alanine amino transferase level was moderately positively correlated with live weight, hot carcass weight, and cold carcass weight. Cortisol level was moderately positively correlated with live weight, hot carcass weight, cold carcass weight, and back fat thickness, and moderately negatively correlated with the lean carcass content. Increased lactate dehydrogenase level was moderately correlated with decreased drip and cooking loss. In conclusion, lactate dehydrogenase could help pork producers predict pork quality variation, while cortisol, alanine amino transferase, and albumin could be useful in prediction of carcass quality.

“…Recent research highlighted that healthy pigs at slaughter can be discriminated from those with health conditions (e.g. lung lesions and abscessation), and those likely to be partially or fully condemned [ 4 , 20 , 21 ], through examination of APP levels. Furthermore, APP levels measured at slaughter were used to discriminate healthy pigs from those with health issues (e.g.…”

Identifying physiological measures of lifetime welfare status in pigs: exploring the usefulness of haptoglobin, C- reactive protein and hair cortisol sampled at the time of slaughter

BackgroundPhysiological measures indicative of the welfare status of animals during rearing could form part of an abattoir-based animal health and welfare assessment tool. A total of 66 pigs were used in this study, the aim of which was to assess how serum concentrations of haptoglobin (Hp) and C-reactive protein (CRP) (assessed in 51 pigs), and hair concentrations of cortisol (assessed in 65 pigs), measured at or close to slaughter, reflected welfare-related indicators recorded from the animal during its lifetime. These indicators were recorded at intervals between 7 and 21 weeks of age and included assigning scores for levels of tail and skin lesions, recording the presence or absence of certain health issues, and conducting qualitative behavioural assessments (QBA).ResultsPigs recorded as having tail lesions during their lifetime had higher hair cortisol levels than those with no tail lesions (tail lesions: 47.87 ± 3.34 pg/mg, no tail lesions: 42.20 ± 3.29 pg/mg, P = 0.023), and pigs recorded as having moderate or severe tail lesions had higher Hp levels than those with no or mild tail lesions (moderate/severe: 1.711 mg/ml ± 0.74, none/mild: 0.731 mg/ml ±0.10, P = 0.010). Pigs recorded as being lame during their lifetime tended to have higher hair cortisol levels than non-lame pigs (lame: 52.72 pg/mg ± 3.83, not lame: 43.07 pg/mg ± 2.69, P = 0.062). QBA scores were not associated with any of the physiological measures (P > 0.05). Receiver Operator Curve (ROC) analysis was also carried out to get a better understanding of the usefulness of the physiological measures in discriminating animals that had had welfare-related issues recorded during their lifetime from those that had not. Hair cortisol was determined as having ‘moderate’ accuracy in discriminating pigs that were tail bitten on-farm from unbitten pigs (AUC: 0.748) while Hp and CRP were determined to have no meaningful discriminatory ability (AUC < 0.600).ConclusionThis research should be repeated on a larger scale, but the results suggest that hair cortisol measured at slaughter could provide insight into the welfare status of pigs during their lifetime. Hp may be a useful indicator of tail lesions in pigs. However, further research utilising a greater proportion of severely bitten pigs is required before conclusions can be drawn.

“…By the content of protein in meat (and the energy contained therein), the Landrace pig breeds surpass the pigs of large white breeds at 6 months of age by 21.1%, and in the 9-month-old by 26.6%. Contents of energy per 1 kg of live weight in the undergrowths of the Landrace breed inferior to large a breed, which suggests a more intense protein synthesis in the Landrace pigs (Klauke et al, 2013).…”

Livestock breeding has a number of technological features. They are related to the specific properties of the object of cultivation – animals. In order to obtain high-quality animals, high-quality products must take into account their genetic features. For example, in pigs, the quality of meat, fat, smoked pork determines the breed of animals, their sex, age and the direction of cultivation. Therefore, the study of the impact of sex and genotype on the productivity of pigs is relevant and practically valuable. There are many literature on the quality of pork animals of various breeds: Landrace, Durok, Great White and others. Scientists note that the best bacon and meat qualities are pigs of pores Landrace. However, scientific literature knows little about the way the sex and origin of animals affect the quality of meat and bacon in these pigs. Therefore, the purpose of our research was to study the slaughter, the qualities of bacon, the physico-chemical indicators of meat and fat females and castrated male species of landraces of two lines List and Brom. During the experiment, zootechnical, statistical, biometric, biochemical methods of research were used. Scientific research was carried out in the complex of fattening and slaughter of the shop of a private enterprise. During the experiment, it was found that the mass of pigs after slaughter, the mass of carcasses and the yield of carcasses of females and castrated males of both lines did not differ. However, the visceral fat content was higher in women by 1.24–8.98% than in men. The properties of the pigs of both sexes were the same. However, in the male line of Brom, the width of the rear half of the carcass was 15% higher than that of women. The assessment of the quality of meat showed that females on both lines dominated by males for the content of fat, marble and calories. It has been experimentally established that the quality parameters of adipose tissue of Landrace have sex differences in the lines List and Brom. It was established that the water content in adipose tissue in women was lower in comparison with men by 0.5–2.35%, the fat was higher than 0.37–3.25%, the iodine number was 3.43–3.68 units. Our research can be recommended to companies that specialize in pig breeding. If a company breeds animals for processing into bacon or smoked, it is advisable to grow a breed from the Brom line. In this case, the best ham can be obtained from castrated males, and juicy, tender meat and more fatty tissue – in females.
