Scawfell Genetics Bull Stud

Domestic Semen Store

The semen store covers all semen that is collected on-farm after obtaining a license for the bull from APHA. The semen goes into quarantine for a minimum of 30 days before being transferred into the semen store. As it enters the semen store its all counted using our new digital optical camera and held until needed.

Scawfell Genetics Ltd semen store is the first in the country that provides a completely automated straw counting system and a portal that allows breeders to see at any time what inventory they have in stock in the semen store.

Each farmer will have his own file and exclusive log in. As the semen comes in to the semen store its added to his stock, the farmer will have access to this 24/7 through an app on his phone. It gives him the ability to see the movement in and out of the semen store at any time as well as being able to check his stock levels.

If you, as the breeder, either want to take semen out of the semen store for personal use or have sold some to another breeder, all we will need is an email stating how many straws you wish to be sent and where to send them too.

The aim of Scawfell Genetics ltd is to have a system that is a cost effective way of managing your semen straws.

At Scawfell Genetics we keep to extremely strict Bio- Security rules ensuring that there is no chance of cross contamination. We follow all the required regulations and take further precautions to make our facility as secure as possible.



Quarantine - Isolation

Bulls arriving on our bull stud go into an isolation pen while they have all their tests, usually for around a month, however, it can take longer occasionally. If they pass the tests they can be moved into the main bull stud.



Semen Collection

Once on the main bull stud semen collection can begin. Semen is collected using natural collection with a teaser as it offers a higher quality sample with a higher fertility rate than electro ejaculation.
