Bull Testing
The Foundation of a successful breeding season starts with your Bulls. Your bulls are the driving force behind herd productivity, if they aren't performing the impact on your bottom line can be significant, no matter the size of your operation.
​
At BL Veterinary Services we pride ourselves on it being stress free, practical and accurate.
Why is Bull Testing Essential for Bull Studs
Running a Bull stud means your reputation depends on the fertility and performance of every bull you sell. Buyers expect confidence in genetics and that starts with proven and trusted reproductive soundness. Bull Testing isn't just a health check, it is a guarantee of quality and trust.
​
Why it Matters?
-
Protect Your Brand Reputation
Every bull leaving your stud reflects your breeding program. Testing ensures you deliver fertile, high performing bulls that meet your buyers expectations. -
Provide Verified Fertility Certificates
Semen evaluation and physical checks by a qualified veterinarian give buyers documented proof of fertility, adding value and credibility to your stud. -
Reduces Risk for Clients
A sub-fertile bull can cost producers thousands in missed pregnancies. Offering tested bulls builds confidence and repeat business. -
Maximise Genetic Potential
Bull testing confirms that your investment in genetics translates into real world performance, strengthening your stud's standing in the market.​
Why Bull Testing is Critical Within a Herd
-
Protect your breeding program
A single sub-fertile bull can result in dozens of missed pregnancies, costing thousands in lost production. Testing ensures every bull is fit for purpose before joining. -
Identify issues before they cost you
Injuries, infections and semen quality problems often go unnoticed until it's too late. Testing prior to joining helps catch these issues early and avoid a poor calving season. -
Maximise Genetic Investment
Bulls represent a major financial and genetic investment. Confirming fertility and soundness protects that investment and ensures your herd achieves its breeding goals.

Bull Fertility Explained
When it comes to breeding success, bull fertility is the foundation. A single sub-fertile bull can cost thousands in missed pregnancies, so understanding the key components of fertility is essential for every cattle producer. At BL Veterinary Services, we break it down into three critical factors:
1. Semen Motility
-
What is it?
Motility refers to how well sperm move. Active, forward-moving sperm are necessary to reach and fertilise the egg. -
Why it matters:
Poor motility means fewer chances of conception, even if sperm numbers are high. Bulls with low motility can dramatically reduce pregnancy rates.
​​
2. Sperm Morphology
-
What is it?
Morphology is the shape and structure of sperm cells. We check for abnormalities in the head, midpiece, and tail. -
Why it matters:
Even motile sperm won’t fertilise an egg if they’re structurally abnormal. High rates of abnormal sperm can lead to poor conception and wasted joining periods.
​
3. Physical & Reproductive Soundness
-
What is it?
This includes scrotal size, testicular health, and overall structural soundness. Bulls must be physically capable of serving cows and maintaining condition during the breeding season. -
Why it matters:
Injuries, infections, or poor structure can limit a bull’s ability to mate effectively, reducing herd fertility.
​
Why Testing is Non-Negotiable
Bull fertility isn’t something you can guess by looking at a bull. Comprehensive testing ensures:
-
Confidence before joining
-
Better conception rates
-
Protection of your genetic investment
