Genetic parameters and mapping quantitative trait loci associated with tibia traits in broilers

B. N. N. Ragognetti, Stafuzza, N. B., Chud, T. C. S., Grupioni, N. V., Cruz, V. A. R., Peixoto, J. O., Nones, K., Ledur, M. C., Munari, D. P., and Silva, T. B. R., Genetic parameters and mapping quantitative trait loci associated with tibia traits in broilers, vol. 14, pp. 17544-17554, 2015.

Selection among broilers for performance traits is resulting in locomotion problems and bone disorders, once skeletal structure is not strong enough to support body weight in broilers with high growth rates. In this study, genetic parameters were estimated for body weight at 42 days of age (BW42), and tibia traits (length, width, and weight) in a population of broiler chickens. Quantitative trait loci (QTL) were identified for tibia traits to expand our knowledge of the genetic architecture of the broiler population.

Application of functional genomic information to develop efficient EST-SSRs for the chicken (Gallus gallus)

Many years of domestication and breeding have given rise to the wide range of chicken breeds that exist today; however, an increasing number of local chicken breeds are under threat of extinction. A comprehensive characterization of chicken markers (especially type I markers) is needed to monitor and conserve genetic diversity in this species. The explosion of genomics and functional genomics information in recent years has opened new possibilities for the generation of molecular markers.
