How to choose ostriches

Individual selection should be based directly on the individual qualities of ostriches. It not only reflects the productivity of the breeding bird, but also reflects the breeding value of the breeding bird to some extent.

Family selection is based on the entire family (including full-sib and half-sib families) as a selection unit, based on the average of family performance.

Pedigree selection is based on the ancestry, siblings, and descendants of the pedigree records for selection and performance.

In practical work, it is necessary to combine the above methods for selection and focus. The young bird breeding stage is dominated by pedigree selection, supplemented by appearance and growth and development identification. When the breeding bird has demonstrated production performance, it is mainly based on individual selection, supplemented by pedigree identification.
