The trial was carried out on 45 pairs of breeders per treatment. Pigeons were fed the two diets ad libitum for 120 days, after which 30 fryer pigeons per group were slaughtered. Half of the refrigerated carcasses were used for analyses of the fresh meat and the remainder was stored under vacuum conditions for 90 days at -18°C. The pectoralis major muscles were removed and analysed for pH, colour, water-holding capacity, tenderness, fatty acids and oxidative stability. The oxidative status of the young birds was affected by the dietary treatment. Generally, the physical traits were better in the supplemented group. The positive effect was more relevant in frozen meat as also denoted by the significant diet x storage interactions. The positive effect of rosemary extract during storage was also confirmed by the lipid oxidation level which, after freezing-thawing, was lower in pigeons in the supplemented group.

To achieve this objective, production factors such as poultry genetics and pasture management should be carefully considered. Furthermore, various aspects of sustainability are analyzed to estimate the environmental, economical, and social benefits promoted by the pasture-based poultry-production systems. There is evidence that poultry meat from alternative production systems contains some additional nutritional benefits through lower fat content, as well as higher vitamin and mineral contents. At the same time, under good pasture management, bird health and welfare significantly improve. Accordingly, this chapter gives an overview of the best management practices that can be employed to obtain high levels of sustainability, animal welfare, and product quality.

The occurrence of Giant Fibres (GF) in three muscles (Pectoralis major (PM), Iliotibialis lateralis and Semimembranosus) with different types of energy metabolism was studied in slow- and fast-growing chicken strains. 2. A total of 20 one-day-old Leghorn chicks (slow-growing) and 20 broiler (Ross 508) chicks (fast-growing) were reared to 100 and 45 d, respectively. 3. A small percentage of GF was seen in pre rigor muscle samples even at 3 min post mortem in both genotypes and in all muscle types studied. 4. From 3 min to 24 h post mortem GF increased both in Leghorn and broiler chickens but to a different extent according to muscle type and genotype. 5. The highest GF 24 h post mortem value was found in the PM muscles belonging to the fast-growing broiler line. 6. It was concluded that every type of muscle can develop GF, but this phenomenon is more evident in the PM especially in animals selected for increased growth rate.

Two groups of 20 male hybrid rabbits were fed the experimental diets from 35 to 80 days of age. Feed intake, live weight, feed eciency and qualitative traits of the carcass and meat were recorded. The a-tocopherol levels in plasma and muscle were signi®cantly higher (p 0. 01) in the supplemented group, which also showed an increase in oxidative stability in both raw and cooked meat. The higher a-tocopherol level improved the physical traits of the meat, signi®cantly reducing shear value and increasing water-holding capacity; n-3 fatty acids in raw and cooked meat increased (p 0. 05) and the thrombogenic index decreased (p 0. 05). Dietary vitamin E did not in¯uence weight gain, feed intake and dressing yield.
