Consumer Dissatisfaction

Meat quality includes intrinsic qualities (the characteristics of the product itself) and extrinsic qualities (e.g. animal health and welfare, environmental impacts, price). There is still a high level of variability in beef palatability, which induces consumer dissatisfaction. We also observe a general trend towards an increasing importance of healthiness and safety (intrinsic) and environmental issues and animal welfare (extrinsic). Most grading systems describe carcasses using only animal traits (e.g. weight, conformation, fatness, animal age and sex). In North American and Asian countries, emphasis has been put on maturity and marbling. The European system is mainly based on yield estimation. The Meat Standards Australia grading scheme, which predicts beef palatability for each cut, proved to be effective in predicting beef palatability in many other countries. Some genetic markers are available to improve beef quality. In addition, gene and protein expression profiling of the bovine muscle revealed that the expression level of many genes and the abundance of many proteins may be potential indicators of muscle mass, tenderness, flavour or marbling of meat. The integration of all these parameters is likely to predict better beef palatability. The integration of extrinsic qualities in the prediction model increases the difficulty of achieving a global evaluation of overall meat quality. For instance, with respect to environmental issues, each feeding system has its own advantages and disadvantages. Despite this, win–win strategies have been identified. For example, animals that were less stressed at slaughter also produced more tender meat, and in some studies the most economically efficient farms had the lowest environmental impact. In other cases, there are trade-offs among and between intrinsic and extrinsic qualities. In any case, the combination of the different integrative approaches appears promising to improve the prediction of overall beef quality. A relevant combination of indicators related to sensory and nutritional quality, social and environmental considerations (such as e.g. carbon footprint, animal welfare, grassland biodiversity, rural development) and economic efficiency (income of farmers and of other stakeholders of the supply chain, etc.) will allow the prediction of the overall quality of beef mainly for consumers but also for any stakeholder in the supply chain.

<p>A total of 168 finishing pigs were used to investigate the effects of gender (barrows and gilts) and transport densities for slaughter (236, 251, and 275 kg/m²) on stress indicators and carcass and pork quality. The animals transported at 251 kg/m² (T251) presented cortisol values below those at 236 kg/m<sup>2</sup> (T236), but no different from those at 275 kg/m<sup>2</sup> (T275). The lactate dehydrogenase (LDH) values in pigs transported at T236 were the lowest. The blood components did not differ between T236 and T275. The pH values at 45 min (pH<sub>45</sub>) and at 24 h (pH<sub>24</sub>) <em>postmortem </em>were higher for pigs subjected to T236. However, the pH<sub>45 </sub>was higher at T251 than at T275, but pH<sub>24</sub> was lower at T251 than at T275. The lightness values in the muscles of the pigs transported at T236 and T251 were higher than those at T275. Lower drip loss values were observed in the muscle of animals at T251. Carcasses of pigs at T236 contained more 1–5 cm lesions while those at T275 contained more 5–10 cmlesions in sections of loin. No significant effects of gender were found on the stress indicators, blood components, pH<sub>45</sub>, pH<sub>24</sub>, color, drip loss or carcass lesions in general. These results indicate that the pre-slaughter transport of pigs at densities of 251 kg/m² generates less physiological damage and smaller losses on carcass and pork quality irrespective of gender.</p>

The Ideal

Abstract In recent decades, the number of birds reared per unit area has dramatically spiked to increase profitability in egg and meat production. However, nowadays, the increase in sensitivity to animal welfare and consumer demands brings along with it a raised interest in stocking density. Stocking density is defined either as the number of animals or body weight per unit area or as the area per animal. High stocking density, which is a stress factor, can be defined as an increase in the number of animals per unit area or a decrease in the area per animal. Stress caused by high stocking density negatively affects the bird’s physiology and performance as well as the quality of the product obtained. The ideal stocking density should be 9 laying hens, 35 kilogrammes for broilers, and 45 quails per square metre. Otherwise, one will observe stress indicators in birds reared in more than the recommended stocking density per unit area and, consequently, a decrease in bird growth, egg production, feed efficiency, and egg or meat quality. Apart from increasing the concentrations of amino acids such as lysine, methionine, tryptophan and arginine, minerals such as selenium and chromium, and vitamins such as C and E in the diet, the addition of additives such as probiotics, humates, phytophenol compounds, and propolis is also effective in reducing or eliminating these negative effects caused by high stocking density. As a result, regulations in the nutrition of animals are effective in reducing/preventing such negative effects, thus improving animal welfare and ensuring the maintenance of optimum yield.

This write up is aimed at proffering solution to the problem of transportation stress in ruminants in the tropics. Ascorbic acid is safe as buttressed in this write up for the improvement of meat quality in short and long terms road transportation stress.This review cover an aspect of animal physiology of stress, veterinary pharmacological aspects of ascorbic acid, how ascorbic acid improved meat product of animals exposed to long transportation stress. Ascorbic acid had no withdrawal period and was scientifically proven to be advantageous to meat characteristics and animal welfare. This was given credence to by its advantages as an anti-oxidative agent in solving the menace of road transportation to veterinarians, animal scientists and other professionals in the livestock industry.
