Broilers'toes asymmetry and walking ability assessment REA
Nääs,Irenilza de A.; Baracho,Marta dos S.; Salgado,Douglas D.; Sonoda,Lilia T.; Carvalho,Victor R. C.; Moura,Daniella J. de; Paz,Ibiara C. L. A..
Brazilian poultry production nowadays occupies important position in world's economy due to its technological advancement, which associated to the development of genetic strains of high growth may cause deviation in the growth rate and harm production. Morphological asymmetry has been pointed as an indicator of welfare, as maintained the pattern that leads to balance, the broiler chicken would have its normal locomotion characteristics, freely reaching water and feed. Thus, the objective of this research was to verify the possibility of using morphological asymmetry for evaluating walking ability of broiler chicken. The research was done in the Technology Center, at UNICAMP. The experiment was made using biomechanics analysis and following, the toes were...

Developmental origins of normal and anomalous random right-left asymmetry: lateral inhibition versus developmental error in a threshold trait Naturalis
Palmer, A.R..
Dramatic examples of right-left asymmetry often inspire adaptive explanations, simply because it is hard to imagine how such forms could not be functionally significant. But are conspicuous morphological asymmetries necessarily adaptive? Surprisingly, in some species where direction of asymmetry is random, asymmetry in bilaterally paired traits may arise as a developmental error in a threshold trait. When cases of asymmetry are rare within a species, they are easily recognized as developmental errors. However, as asymmetrical individuals become more common, or if the asymmetry is in a signaling trait, the temptation to advance an adaptive explanation grows, particularly if the asymmetry is not clearly maladaptive. Several models of the ontogeny of...
