What sets St.Cyr Brahmans apart from the rest is that we have maintained a concentrated linebred selective breeding program with Imperator genetics, as opposed to an outcrossed breeding program. We have selectively bred our cattle within a particular line of descent to perpetuate desirable characteristics.
Linebreeding involves breeding to fairly close relatives whereas outcrossing involves breeding to non-relatives or to very distant relatives. Both linebreeding and outcrossing have advantages and disadvantages. When executed properly, linebreeding can present numerous benefits including but not limited to:
- Ability to identify genetic lines with no flaws or to eliminate existing flaws within specific gene pools
- Progeny that will provide significant hybrid vigor when outcrossed with non-relatives
- Production of more consistent and uniform offspring
- Sustainability of more consistent excellence
Linebreeding does produce more consistent and uniform offspring, but the progress toward higher levels of performance can be slower than that of outcrossing. However, the progress made through linebreeding will be sustainable in future generations within the line, and will provide superior hybrid vigor when linebred offspring are out crossed with non-relatives.
The primary advantage of outcrossing is hybrid vigor in early generation crosses; however, with continual outcrossing, this advantage declines in each successive generation. Whereas the advantage of hybrid vigor is more sustainable from linebreeding.
Performance plus predictability is our genetic program. We believe the benefits of utilizing linebred genetics on outcrossed cattle are phenomenal and we hope to serve as your source of Brahman genetics so that you may witness these results for yourself.
