SA31A

Breeder hen SA31A

 

This red-coloured hen is adapted to farmhouse, pastured and "3 week old reared pullets" productions, for open air or enclosed rearing.

 

 

 

  • Dwarf size
    The dwarf size reduces the cost of raising breeding flocks, in both feed and equipment terms.
    This genetic characteristic is located in the sex chromosomes (Z in birds, ZZ in the male and Z- in the females). If you mate a dwarf hen with a normal size cock you will get a normal size broiler.

    Another great advantage: the SA51 and SA51A birds are colour recessive, in other words their descendents have the same characteristics as their fathers. Thus, although the SA31A hen has red plumage, a dark-colored under-plumage, a yellow skin and a feathered neck, by crossing her with a type T55 cock, you will get a T531A end product with red plumage, light under-plumage and white skin, just like its father.
  • Ease of sexing
    The descendents of the SA31A breeder hen can be sexed using their wing feathers. This is certainly an advantage when rearing the two sexes separately.
