Galinha com Quatro Asas? Entenda o que é a Asa Dividida (Split Wing)

📘 Secure your copy of the Poultry Genetics Treatise here: https://go.hotmart.com/R106024761W?dp=1 Does your chicken seem to have "four wings"? Or perhaps you have a bird in your flock with a drooping wing or completely twisted flight feathers? In this video, Ricardo Dornas explains the hidden anatomy of bird wings and unravels the mystery behind three very common but poorly understood conditions: Split Wing, Twisted Feather, and Slip Wing. Understand the biological role of the axial feather, the first to develop in the embryo, and how its absence or malformation affects the aesthetic standard and zootechnical performance of your flock. To download supporting materials and follow our field research, visit our official website: www.chacaradornas.com.br. Discover why the Split Wing is not considered a defect, but rather a mandatory and desirable trait in hard-feathered fighting breeds like the Ko-Shamo and Asil, even being associated with greater weight gain and hardiness. Ricardo also addresses the complex threshold genetics behind these characteristics of variable expressivity and launches a scientific challenge to the community: a project of experimental crossbreeding and collective mapping to definitively unravel the heritability of these mutations. Topics covered in the video: Wing Anatomy: Homology with mammalian limbs and the standard count of the 10 primary and secondary feathers. The Axial Feather: The evolutionary and embryonic importance of the central feather that divides the flight groups on the bird's wrist. The 3 Wing Mutations: Visual and diagnostic differences between Split Wing (physical defect), Twisted Feather (calamus twist), and Slip Wing (muscle weakness/droop). Breed Standard vs. Defect: Why split wings are required in Ko-Shamo chickens and how to safely identify the condition after the 30th week of life. Threshold Genetics and Expressivity: Why the mutation can appear on only one side of the bird and how to conduct selection management.
