Bull Semen Collection and Freezing
Bull semen collection is a relatively straightforward process that is followed by a series of strict handling and laboratory protocols to ensure high quality semen after freezing. Every batch of semen frozen is then put through a thorough post-thaw assessment to ensure that the quality is appropriate for use in Artificial Insemination or donor programs.
Semen can also be collected, analysed and extended to use fresh in AI programs. Repro Hub offers storage of frozen semen or it can be delivered back to the producer.
Repro Hub has trained with Jasmin Hyatt, Veterinary Reproduction Specialist of Veterinary Reproduction Consultancy in Orange. Kristen has also sought out extra-mural training in semen handling domestically and carried out an internship at World West Sire Services in Montana, USA in 2024. All with the aim of ensuring an exceptional quality product every time.

Allowing the genetics to be available to other producers
FAQs
How many straws will I get from one collection?
The number of straws for any one collection will differ significantly based on the individual bull. They may give from 50 to 500 straws. Not every bull will give a good, high quality semen sample that survives the freezing process on the first go. Often, more than one attempt is required.
Do you come on-farm for collection?
Yes, we do. We also house bulls on-centre at Woodstock for collection in our state-of-the-art facilities.
Do I need to do anything in preparation for collection?
For best results, bulls should be in good body condition and physical health. Having served a female(s) in the weeks prior is an advantage but not a strict requirement. Similarly, for best results, it is advised that they have not had access to females in heat in the 3-5 days ahead of collection.
What collection methods are used?
The collection process used on farm is electro-ejaculation. All bulls housed on-centre are collected using a hand-held Artificial Vagina when they mount a teaser animal.
