The incidence of dead on arrival (DOA) birds was surveyed over 33 broiler, 11 turkey, and 19 spent hen abattoirs representing the majority (around 70%) of the Italian poultry slaughter plants. Data were recorded monthly during a 4-yr period (August 2001 to July 2005), considering a total of 1266 million chicken broilers, 118 million turkeys, and 54 million(More)
We assemble the spectrum of single-trace operators in free N = 4 SU(N) SYM theory into irreducible representations of the Higher Spin symmetry algebra hs(2, 2|4). Higher Spin representations or YT-pletons are associated to Young tableaux (YT) corresponding to representations of the symmetric group compatible with the cyclicity of color traces. After turning(More)
We test the spectrum of string theory on AdS5 × S5 derived in hep-th/0305052 against that of single-trace gauge invariant operators in free N = 4 super Yang-Mills theory. Masses of string excitations at critical tension are derived by extrapolating plane-wave frequencies at gYM = 0 down to finite J . On the SYM side, we present a systematic description of(More)
Two field experiments were conducted to evaluate the efficiency of Rusa deer in the development of the cattle tick Boophilus microplus in comparison with that of steers in the same pastures and under the same conditions of infestation. No difference was noted between a mixed steer/deer herd and a pure steer or pure deer herd in the infestation pattern of(More)
A study was conducted to determine the incidence of deep pectoral myopathy (DPM) in male roaster chickens reared under intensive conditions, processed at different ages (from 47 to 65 d of age), and belonging to 2 commercial genotypes (Ross 508 and Cobb 500). The study was carried out in a major Italian processing plant on a total of 120,700 male roaster(More)
The variation in broiler breast meat color (CIE values L*a*b*) that normally occurs during processing was evaluated on 6,997 broiler breast fillets (pectoralis major muscles) from 79 flocks using a Minolta Chroma Meter. The samples were randomly collected at 3 to 6 h postmortem from the deboning line at a single major Italian processing plant. In addition,(More)
Over the past 15 yr, the European poultry processing industry has gradually increased the availability of poultry meat in a large variety of processed ready meals following what occurred a few years before in North America. This shift toward further processed products has emphasized the necessity for higher standards in poultry meat to improve sensory(More)
A study was conducted to determine the influence of genotype, market live weight, transportation time, holding time, and temperature on broiler breast fillet color under commercial processing in Italy. Color was evaluated using a Minolta Chroma Meter (Minolta Chroma Meter CR-300, Minolta Italia S.p.A., Milano, Italy) on a total of 6,997 broiler breast(More)
The influence of the season and market class of broiler chickens on breast meat quality traits was determined on a total of 18 flocks reared and processed under commercial conditions. According to the Italian poultry production system the following classes of birds were considered: light size (1.2 kg of carcass weight; n = 90) and medium size (1.8 kg of(More)
The appearance of whole carcass and skin-on cut-up products is an important attribute that deeply affects the consumer's choice. Skin pigmentation is affected mainly by genetics, concentration and dietary source of pigments, health status of the birds, and scalding-plucking conditions during slaughtering, although other factors might play an important role.(More)
