“…Free-range and organic poultry production systems have increased in recent years worldwide, and it is widely known that the suitability of the genetic strain to extensive environments largely affects the animal welfare and the meat and egg characteristics [6,33]. In fact, when poultry are reared under extensive system having access to pasture, health, welfare, meat and egg quality parameters result enhanced [34,35].…”

“…In free-range poultry systems, runs are often not well managed and animals may not feel safe in it. Outdoor runs could be made more attractive by offering different kinds of shelter [4,6]. A free-range area contributes to the welfare of laying hens.…”

“…In addition, poultry have specific requirements for essential amino acids, in particular lysine and methionine. In conventional systems, feeds are supplemented with synthetic amino acids, but these are not permitted in organic systems, so alternative sources, such as natural essential compounds from plants and vegetables, have to be investigated [5,6]. It is often difficult and expensive to source these products, and they are major contributors to the high cost of feed.…”

Feeding Forage in Poultry: A Promising Alternative for the Future of Production Systems

Abstract:The present review discusses the existing research findings on the nutritional impact of forages in poultry diet and the significance of forages in sustainable poultry production systems. The nutritional composition and antinutritional factors of the main forages and the pros and cons of feeding forage on poultry meat and egg quality under free-range and organic production systems are also discussed. This review highlights the importance of forages and forage meals in poultry ration, considering that these feedstuffs may have greater value to the success of local poultry production in many regions of the world due to their potential of production.

“…It can be speculated that DHA was more effectively converted from ALA because its content decreased in a similar way. This assumption is related to the observation of Ponte et al (2008) and Dal Bosco et al (2014) that low levels of pasture intake did not contribute to increasing the ALA in breast meat, whereas the desaturation and elongation of this fatty acid precursor may contribute to the synthesis of its long-chain fatty acids derivatives. Regarding the FA group, the PUFA content was significantly lower in the free-range chickens with lower stocking density.…”

“…Three feed mixtures were fed during the experiment: a starter until 28 days of age, a grower between 29 and 42 days doi: 10.17221/79/2016-CJAS of age, and a finisher from 43 to 55 days of age (Table 1). Pasture intake was indirectly assessed by a modified method of Dal Bosco et al (2014). Pasture samples were collected in each of square areas (50 × 50 cm) and then calculated for the whole area of each pen.…”

Skřivanová V., Tůmová E., Englmaierová M., Chodová D., Skřivan M. (2017): Do rearing system and freerange stocking density affect meat quality of chickens fed feed mixture with rapeseed oil? Czech J. Anim. Sci., 62, 141−149.Recently, consumers have paid an attention to animal-friendly meat. The aim of the study was to evaluate the meat quality of breast muscles in indoor and free-range chickens with respect to the stocking density of outdoor chickens (8.3 or 4.15 birds per m 2 ) fed feed with rapeseed oil. The free-range chickens reached 96 and 97% of the final live weight of the indoor chickens and their feed : gain ratio was by 7 and 9% higher. The pasture intake had a small effect on the breast meat quality and was presumably associated with rapeseed oil in the basal diet which strongly influenced meat monounsaturated and polyunsaturated fatty acid content and reduced the effect of pasture. The free-range system and lower stocking density led to an increase in muscle fibre cross-sectional area and diameter and a higher meat shear force (P = 0.003). Concerning the meat sensory properties, the total acceptability of the meat of free-range chickens with a lower stocking density was found to be lower compared with the other groups. Results indicate a minor effect of the rearing system and free-range stocking density on chicken meat quality, and also that meat quality in experiments with free-range housing can be affected by a fat source in basal diet.
