Production-specific factors, such as breeding, diet, and stress, are known to influence meat quality, but the effect of different husbandry systems on the development of quality parameters and shelf life has hardly been investigated. Thus, the aim of the study was the investigation of an alternative production system based on a slow-growing, corn-fed, and antibiotics-free chicken line compared with conventional poultry production. Additionally, the effect on meat quality, microbiology, and spoilage was analyzed. In total, 221 breast filets from a German poultry meat producer were investigated. Nutritional, biochemical, and cooking loss analyses were conducted on a subset of samples 24 h after storage. The rest of the samples were stored aerobically at 4°C, and the spoilage process was characterized by investigating pH, color, lipid oxidation, microbiology, and sensory attributes subsequently every two days during storage. The alternative production line showed a significantly healthier nutritional profile with a higher protein and lower fat content. Additionally, the amount of L-lactic acid and D-glucose was significantly higher than in the conventional production line. The color values differed between both production lines, with the corn-fed line displaying more yellowish filets. The lipid oxidation and microbial spoilage were not affected by the production line. The shelf life did not differ between the investigation groups and was deemed 7 days in both cases. Despite the highest severity of white striping being observed most in the conventional production line, there was no overall difference in the incidence among groups. The purchase decision was affected by the occurrence of white striping and showed a tendency for a higher acceptance for the alternative production line.

Any evaluation of breeds or production systems for beef must consider effects on production, carcass and meat quality characteristics. Holstein-Friesian (HF) cattle are bred for dairy traits only, while Norwegian dairy cattle (NOR) have been selected with some emphasis on beef characteristics. A comparison of production data from bulls of these two breeds has been presented previously (Kirkland et al., 2005). The objective of the present study was to evaluate specific carcass and meat quality parameters of HF and NOR bulls.

Study Results

Bearing in mind certain established European Union regulations on non-industrial poultry meat production, experimental investigations were conducted with the aim to examine the effect of two different rearing systems (free-range rearing and extensive rearing in the chicken pen) on some meat quality characteristics. Investigation results on the shares of muscular tissue, bones and skin in major carcass parts (breasts, thighs and drumsticks) were used as poultry meat quality parameters. Based upon the obtained study results, it could be concluded that a somewhat higher meat share in breasts and drumsticks was recorded with the free-range-reared broilers as compared to the extensively reared ones. A somewhat higher meat share in the drumsticks was registered with the hens whereas other differences from the point of view of the sex effect were small.

The effects of sex and production systems on carcass yield, meat quality and proximate composition of sub-adult impala were evaluated by culling 35 impala from intensive (12 males) and semi-extensive (12 males and 11 females) production systems within the same game farm. While no sexual dimorphism was found for carcass weights, male impala had a higher dressing percentage than females, indicating a higher meat production potential. Few differences were observed for yields between the male impala from the different production systems, but physical meat quality parameters indicated possible stress for those kept intensively. Minor differences existed in physiochemical parameters between various impala muscles for the two sexes and production systems, providing little motivation for these factors to be considered when processing sub-adult impala carcasses. Impala meat from both sexes, all muscles and all production systems produced meat with shear force values below 43 N, and thus may be considered as tender. Furthermore, the proximate composition of all impala meat in this study ranged from 74.7 to 77.0 g/100g moisture, 20.7 to 23.5 g/100g protein, 1.2 to 2.2 g/100g fat and 1.1 to 1.3 g/100g ash content. These values compare favorably to other game species, indicating that impala meat may serve as a lean protein source.

Bearing in mind both certain established European Union regulations on the non-industrial poultry meat production and rearing specificities in our conditions, experimental investigations were conducted with the aim of examining the effect of two different rearing systems (outlet fattening and extensive rearing in the chicken-pen) on major quantitative characteristics of dressed broiler carcasses. The initial material used in the experiment consisted of one-day old chickens of the Hybro G strain. Following the 56-day fattening period, the shares of dressed carcasses, slaughter by-products, abdominal fat and basic carcass parts were determined by measuring at the slaughter line. Based upon the data mentioned, major quantitative meat parameters of trial broilers were calculated. The research results analyzed lead to the conclusion that there are no particularly significant differences between the outlet-reared broilers (one chick per square metre of the outlet area) and the extensively reared ones (12 broilers per square metre of the floor area) in terms of major slaughter characteristics.

Cereal grains and soybean meal are the main feedstuffs used in swine and poultry feeding, two of the most consumed meats and of key relevance to food security worldwide. Such crops are grown mostly in North and South America and transported over large distances creating sustainability concerns and, furthermore, are in direct competition with human nutrition. Alternatives to these ingredients are, thus, a pressing need to ensure the sustainability of swine and poultry production. Microalgae seem to be a viable alternative due to their interesting nutritional composition. The use of different microalgae in monogastric feeding has been addressed by different researchers over the last decade, particularly their use as a supplement, whilst their use as a feed ingredient has been comparatively less studied. In addition, the high production costs of microalgae are a barrier and prevent higher dietary inclusion. Studies on the effect of microalgae on meat quality refer mostly to fatty acid composition, using these either as a functional ingredient or as a feedstuff. Within such a context and in line with such a rationale, in this review we address the current research on the topic of the use of microalgae in poultry and swine nutrition, particularly aspects concerning pork and poultry meat quality and nutritional traits.

Poultry meat is often stored in modified atmosphere packaging (MAP) or vacuum packaging to improve consumer acceptance and shelf life. The aim of this study was to determine how different packaging conditions influence meat quality. Therefore, in three independent experiments, turkey breast muscle cutlets were packaged either in vacuum or in different modified atmosphere mixtures (80% O2, 20% CO2 [MAP 1]; 80% N2, 20% CO2 [MAP 2]; and 20% O2, 20% CO2, 60% N2 [MAP 3]) and stored for 12 days at 3°C. Color, pH, electrical conductivity, total viable counts, and Pseudomonas species were determined on days 1, 4, 8, and 12 of storage. On the same days, samples were collected for analysis of thiobarbituric acid–reactive substance and total volatile basic nitrogen concentrations. Sensory parameters and liquid loss were determined on days 4, 8, and 12. Vacuum-packaged meat had the highest liquid loss and lowest sensory results. MAP 1–packaged meat showed the highest sensory, redness, and thiobarbituric acid–reactive substance values. MAP 2–packaged meat had lower sensory values. MAP 3–packaged meat had lower redness and sensory values, especially at the end of storage. The study showed an impact of the packaging condition on different quality parameters, with a small advantage for storage of turkey cutlets in high-oxygen packages.
