Holstein Frozen Semen

Our Holstein genetics programme sources from internationally indexed bulls with published production and functional-trait proofs. Every straw is colour-coded, batch-numbered and accompanied by a certificate of origin and a genomic index sheet. Sexed product is sorted at 90% female accuracy and validated per batch.

We advise on sire selection against your herd’s current production curve, calving pattern and milk payment scheme, so that genetics spend translates into measurable margin rather than catalogue novelty.
