Advantages of semen freezing

  • MORE BREEDINGS The ejaculate is divided into multiple doses, meaning more females can be bred with a valuable chosen genetics

  • GENETIC GAIN Fast genetic progress through expansive use of desired genetics

  • ECONOMICAL Purchasing frozen semen is more economical than investing in multiple expensive bulls, so frozen semen doses can be sold to vendors nationwide.

  • TRANSPORTATION Semen can be shipped nationwide, mitigating all risk associated with live animal transport and housing. 

  • EFFICIENCY Know you have the required amount of doses ready for your AI program, making for a well planned and efficient breeding season

The freezing process

Following dilution, the sample is processed as follows

1. Cooled to 5 degrees at a controlled rate

2. Packaged in labelled STRAWS

3. Held above liquid nitrogen vapour

4. Plunged into liquid nitrogen (-196 degrees)

5. Stored in liquid nitrogen tanks

6. A sample straw is thawed to assess how it has tolerated the rigorous freezing process and ensure minimum standards are met.

Straws can be stored at KB Livestock Services.
