Abstract The performance and the behaviour of three different chicken strains, reared according to the EEC-Regulation 1804/1999 on organic system, were compared. The strains had very slow (Robusta maculata), slow (Kabir) and fast (Ross) growing rates, respectively. The trial was carried out on 200 chickens (male and female) per strain. Rearing lasted 81 days as required by the EEC Regulation. At slaughter age, 20 birds per group were killed. Robusta maculata and Kabir chickens showed more intense walking activity and better foraging aptitude; their antioxidant capacity was also superior. Ross chickens had a good growth rate and feed conversion index, reaching an excellent body weight, but the mortality and the culling rate were high indicating that fast-growing strains do not adapt well to organic production. Robusta maculata showed the worst productive performance although the mortality was low and Kabir birds gave intermediate results. The carcass traits were the best in Ross and the poorest in Robusta maculata. Male chickens were heavier and leaner than females.

- Comparison of two chicken genotypes organically reared: oxidative stability and other qualitative traits of the meat (2006, background): “In general, the meat of organic chickens has a considerable amount of malondialdehyde (Castellini et al., 2002a) since the oxidative status of the organic animals is affected by the intense motor activity which in turn increases muscle oxidative metabolism and free radical production.”
- Growth Performance, Carcass Traits and Meat Quality of Slower-growing and Fast-growing Chickens Raised with and without Outdoor Access (2011, background): “Sci. 24(10):1407-1416 1414 contrast to the present results, Lewis et al. (1997), after 48 days fattening, and Castellini et al. (2002c) both slaughtered broilers at the 82nd day of age and reported that FG chicken had higher abdominal fat ratio than SG.”
