Semen Freezing and Storage

On arrival at WESTBREED every ram is clinically examined by one of our Veterinarians to ensure they are in good health and do not pose a biosecurity risk to other animals within the Centre.

Semen and blood samples are taken for analysis by the Department of Agriculture Animal Health Laboratory to detect the presence of fertility diseases that can be transmitted by semen. Once clear, semen collection and processing begins.

 

Each ejaculate is analysed by spectrophotometer for spermatozoa concentration to determine the correct rate of dilution. This is your guarantee that each semen dose has sufficient viable sperm as specified by the Australian Reproduction Veterinarians Association industry code of practice.

 

Extended semen is packaged and sealed automatically in individual dose 0.25 ml PVC straws eliminating the potential for cross identification. Biosecurity and Quality Assurance is top priority at WESTBREED.

 

Individually labelled and sealed straws ready for freezing.

What you see is what you get. Pellet frozen semen cannot be identified, cannot be protected from cross contamination and cannot be used or sold in single doses.

Secure storage in liquid nitrogen at -196 degrees Celsius. There is no better insurance for your valuable genetics than cryo-preservation of both semen and embryos.

Little, if any, deterioration in fertility of genetic material has been detected when stored for decades. Liquid Nitrogen storage tanks are checked and filled weekly and storage is charged every 6 months according to your inventory.
