“…The study by Leinonen et al (12,13) found that organic poultry systems have higher AP and EP than other systems considered. However, opposite results have also been observed, showing that organic or other extensive forms of livestock production can reduce the use of fossil fuels, fertilisers and other inputs (19)(20)(21) or have lower emissions from housing (22) , and therefore they can be equally or less environmentally impacting than intensive systems.…”

The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40–60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

“…Indeed, the feed represents the greatest part of the economic and environmental costs of poultry rearing (Boggia et al, 2010). The use of local whole grains has been of interest to reduce the feed costs caused by transport, handling and processing (Dozier et al, 2006).…”

The aim of this trial was to study the influence of feed form on the performance, gizzard development and carcass traits of growing geese. Between 42 and 98 days of age, 360 geese (type Maxipalm R ) were fed a diet containing 500 g sorghum/kg (nitrogen-corrected apparent metabolizable energy 12.6 MJ/kg, 15.1 g/kg CP). Birds were divided into three groups differing in feed form: complete pellets (Control group, n 5 120); a coarse-ground meal (CG group, n 5 120); or a mixture containing protein-rich pellets and sorghum whole grains (M group, n 5 120). Feed intake per pen (40 birds/pen) was measured weekly between 42 and 98 days of age, and individual live weight (LW) was measured every 2 weeks. At 84 and 98 days of age, 12 birds were slaughtered in each group to measure the gizzard development and body traits. Irrespective of the goose sex, LW at 98 days was lower for the CG group than for the Control group (5555 v. 5888 g, P , 0.05 for males and 5039 v. 5215 g, P , 0.05 for females). The feed intake over the entire period was 5.5% higher in the M group (P , 0.05) than in the Control and CG groups but the feed conversion ratio (6.91, P . 0.05) was similar in the three groups. The gizzard development (as % of LW) was higher in birds of the CG group than those of the Control and M groups at 84 days of age (113.98% and 113.51%, respectively; P , 0.05) but was similar in all three groups at 98 days of age (4.01%, P . 0.05). The relative liver development was lower in the birds of the CG group than those of the other two groups at 84 and 98 days of age (220%, P , 0.001 and 210%, P , 0.05, respectively). The other body traits were similar in the three groups at both 84 and 98 days of age. The present results suggest that a simplified diet presented in the form of a mixture of sorghum whole grains and protein-rich pellets did not reduce the performance of growing geese.

“…Although the concept of sustainable development was officially promoted in the late 1980s, there is still no precise definition of this phenomenon (Daly, 1996;Atkinson et al, 2007). Nevertheless, there is a consensus among the authors that each economic activity depends on the global ecosystem (for its resources and for the absorption of pollutants) and that sustainable development is possible only if an integration of three different dimensions -economic, social and environmental is achieved (Jovanović-Gavrilović, 2003;Rodić et al, 2007a;Boggia et al, 2010).…”

The influence of strain and age on some egg quality parameters of commercial laying hens

The experiment was conducted to evaluate the influence of strain and age on some egg quality parameters (egg weight and egg shell strength) of commercial laying hens. Layers of lines ISA Brown and DeKalb White were examined in period of nine months. Both lines were at same age (28 weeks) and were confined in common facility in battery cages. Laying hens were reared and fed according to standard breeding technology. Once a month 25 eggs of each line were taken to be examined for eggshell strength and egg weight, or in other words, total 450 table eggs were tested. Analises were done in Laboratory for testing egg quality by gaudges Egg Multi Tester EMT 5200 and Egg shell Gauge (Robotmation Co. Ltd., Tokyo, Japan) which have computerised equipment to examine quality and physical characteristics of eggs. Statistic analyses on results were done by computer sub-programme ANOVA and Fisher's LSD test to determine the level of statistical significant difference between examined factors. Egg weight was under significant impact of age (P ? 0,05), but not under the influence of strain, although eggs of ISA Brown line were insignificantly heavier than eggs of DeKalb White line. Eggs were heaviest at layers with older age, while they were lightest at younger birds. The results have shown significant differences (P ? 0,05) in eggshell strength compared to line influence (genotype) and months of age. Eggs from ISA Brown laying hens had much better and eggshell strength than those eggs from DeKalb White. Correlations between eggshell strength and egg weight were with significant (R < 0,05) negative value, which indicating that with increasing egg weight decreases of eggshell strength.
