Elite Sexed Fertility


Elite Sexed Fertility

Select Sires continues to innovate the use of data to benefit customer-owners as the first A.I. organization to identify our highest performing sires for sex-sorted semen in both 2M and 4M products. The addition of the Elite Sexed Fertility designation provides a useful new tool to help you maximize success with gender SELECTed SexedULTRA semen.

What we have learned

Select Sires has collaborated extensively in research, leading to improvements in fertility potential of sex-sorted semen. However, research trials and field fertility data clearly and repeatedly confirm that some sires achieve much greater conception rates than others, irrespective of sperm dosage.

Composite Fertility Index

Select Sires constantly monitors the success of both conventional and sex-sorted semen through a Composite Fertility Index (CFI) that combines information from several large-scale sire fertility analysis systems. Elite Sexed Fertility sires have been identified through their above average conception performance with sex-sorted semen.

Ensuring the best return on investment

This new designation comes to Select Sires as result of extensive data analysis and the cooperative is excited to offer customer-owners another tool to enhance genetic and reproductive success. In its true cooperative form, Select Sires believes in developing and offering product lines that ensure the best return on investment for dairy producers.
