Semen Inventory Management
When you're managing frozen semen from multiple stallions across multiple storage locations, you need to know exactly what you have, where it is, and when it expires. Manual tracking with spreadsheets leads to lost doses, expired inventory, and confusion about what's been used.
BreederHQ tracks semen inventory at the dose level with complete chain of custody from collection through use.
The complexity of semen inventory
Managing semen inventory involves multiple moving parts:
- • Multiple stallions - Each with different quality characteristics, collection frequency, and demand.
- • Multiple storage types - Fresh (hours), cooled (days), and frozen (years) with different handling requirements.
- • Multiple locations - Semen stored at your facility, at a collection center, or shipped to distribution centers.
- • Quality tracking - Not all batches are equal. You need to know which batches have the best quality for your most important breedings.
- • Expiration management - Cooled semen expires quickly. Even frozen semen has recommended storage limits.
- • Chain of custody - Who received what, when, and for what purpose? Especially important for shipped semen.
Without proper tracking, you lose visibility into one of your most valuable breeding assets.

- • Collection facility
- • Technician/collector name
Initial Assessment
- • Volume collected
- • Raw concentration
- • Initial motility assessment
- • Processing notes

Quality Tracking
Not all semen batches are equal. Track quality metrics so you can make informed decisions about which batches to use for which purposes. These are the headline numbers shown on every lot. For breeders who need the full picture, including multiple analyses per donor, trend lines over time, and the original lab reports, see Semen Analysis Records below.
Quality Metrics
Concentration
Sperm count per milliliter. Higher concentration means more sperm per dose, which can improve conception rates.
Motility
Percentage of sperm actively swimming. Critical for fertilization success. Track pre-freeze and post-thaw motility for frozen semen.
Morphology
Percentage of normally-shaped sperm. Abnormal morphology can reduce fertility even with good motility.
Excellent Quality
High concentration, >60% motility post-thaw, normal morphology. Use for your highest-priority breedings or premium AI shipments.
Good Quality
Adequate concentration, 40-60% motility post-thaw, mostly normal morphology. Standard breeding quality.
Fair Quality
Lower concentration or motility (25-40%). May require double-dose insemination. Use before it degrades further.
Poor Quality
Below viable thresholds. Consider discarding or use only for low-priority situations where pregnancy isn't critical.
Semen Analysis Records
Included on the Pro plan
A single motility number on a lot tells you almost nothing. Quality changes between collection and freeze, between freeze and thaw, between this year and last. Real reproductive recordkeeping treats every analysis as its own dated record, not a value you overwrite each time you run a new test.
BreederHQ stores every analysis as a permanent record tied to the donor, the lot, and the original lab report. Every test is preserved. Every report is searchable. Every number has provenance.
One Donor, Many Analyses
The same donor and the same lot can be analyzed in different contexts. Each one is its own record, with its own date, operator, and result set.
Fresh Collection
Initial analysis at the moment of collection, before extender or processing.
Chilled / Cooled
Quality check after cooling, before shipment or use.
Post-Thaw
Quality after thawing frozen doses. The number that actually predicts success.
Re-Test
Follow-up analysis on an existing lot, months or years later. Confirms doses still meet the standard.
Breeding Soundness Exam (BSE)
Full evaluation tied to the donor, not a specific lot. Documents the animal's overall breeding fitness for the season.

Upload a lab report. We do the typing.
Most labs hand you a PDF. Re-typing twenty fields into a form is where good intentions die. Upload the report and BreederHQ reads it for you.
- 1 Drop the PDF (or photo) onto the analysis record
- 2 The system reads the report and pre-fills every field it can identify
- 3 Review the extracted values side-by-side with the original PDF
- 4 Edit anything that needs correction, then commit
- 5 The original report stays attached to the record forever
You always see and approve the values before they're saved. No surprises, no silent edits.
Quality history, not a single snapshot
Every analysis adds a point to the donor's trend chart. See whether a stallion is improving, holding steady, or declining, with the data to show buyers, vets, or future partners.
Per-Donor Trends
Chart total and progressive motility, concentration, and morphology across every analysis on file. Spot patterns long before a problem becomes a missed breeding season.
Per-Lot History
Open any lot and see every analysis ever run on it: initial freeze, first post-thaw, the re-test you did last year. Buyers and vets get the full picture, not just the headline.
Compare Analyses
Stack two or more analyses side-by-side. Useful for confirming a re-test result, settling a dispute, or showing a buyer the trajectory of a young donor.
The lot summary becomes trustworthy
The motility and concentration shown at the top of every lot used to be free-text fields, populated by whatever someone typed when the lot was created. With analysis records in place, those headline numbers can pull from the most recent confirmed analysis, with a clear label showing whether the value is manual or derived from verified lab data.
You'll always know which numbers come from a real test and which ones are someone's best recollection.

Frequently Asked Questions
Can I track semen from outside stallions?
Yes. Track semen you own from outside stallions the same way you track semen from your own stallions. Record storage location, quality metrics, and usage. When you use it for breeding, the system links to the appropriate stallion record.
How does dose-level tracking work?
Each batch is recorded with a total dose count at collection. As you dispense doses-whether for breeding, shipping to mare owners, testing, or discard-the system automatically decrements the available count. You always know exactly how many doses remain per batch.
What quality metrics are tracked?
Record concentration (million/ml), motility percentage, and morphology assessment for each batch. Assign visual quality grades (Excellent, Good, Fair, Poor) for quick reference. Quality data helps you prioritize which batches to use for breeding vs. shipping. Pro plans add full semen analysis records, including multiple tests per donor or lot, detailed motion metrics, and attached lab reports.
Can I track semen quality over time?
Yes, on the Pro plan. Every semen analysis is stored as its own dated record, not a value that gets overwritten. Each donor has a quality history chart showing total motility, progressive motility, concentration, and morphology across every analysis on file. Each lot shows every test ever run on it-initial freeze, first post-thaw, follow-up re-tests. You can show buyers, vets, or partners the actual trajectory of a donor instead of one number from one day.
Can I upload lab reports?
Yes, on the Pro plan. Drop a PDF or photo onto an analysis record and BreederHQ reads the report and pre-fills every field it can identify. You review the extracted values side-by-side with the original report, edit anything that needs correction, and commit. The original PDF stays attached to the record permanently. You always see and approve the values before they're saved.
What types of semen analyses can I record?
Five types: fresh (at collection), chilled/cooled (before shipment or use), post-thaw (after thawing frozen doses), re-test (a follow-up analysis on an existing lot), and breeding soundness exam (BSE), a full evaluation tied to the donor, not a specific lot. The same lot can have all five over its lifetime, each as its own record.
Will the headline numbers on a lot stay accurate over time?
Yes. The motility and concentration shown on each lot can pull from the most recent confirmed analysis instead of being a free-text field someone typed once. Every value is labeled so you know whether it came from a verified lab report or was entered manually. You always know which numbers are trustworthy and which are someone's recollection.
What is CASA?
CASA stands for computer-assisted semen analysis. It's the lab equipment most reproductive vets use to measure motility, concentration, morphology, and detailed motion metrics like VCL, VAP, VSL, LIN, and STR. If your vet sends you a CASA report, BreederHQ can parse it, pre-fill the analysis record, and keep the original PDF attached. You don't need to know what any of the acronyms mean to use the feature. Just upload the report.
How do expiration alerts work?
The system calculates expiration dates based on storage type: fresh semen (hours), cooled semen (days), frozen semen (years). Dashboard alerts highlight batches expiring within 30 days. You can set custom thresholds for alerts.
Can I track semen shipped to mare owners?
Yes. When dispensing semen for shipment, record the recipient name, address, carrier, and tracking number. This creates a complete chain of custody from collection through delivery. Link shipments directly to breeding attempts in breeding plans.
Does it integrate with breeding plans?
Yes. When you log a breeding attempt using AI, you can link it to a specific semen batch. The system automatically decrements the dose count and creates an audit trail showing which semen was used for which breeding.
