Equine Artificial Insemination Training

Lesson 1 • Palpation and Ultrasound Landmarks

Introduces rectal palpation and transrectal ultrasound for identifying reproductive structures. Builds tactile and imaging skills essential for cycle monitoring.

Lesson 2 • Reproductive Physiology Fundamentals

Explains hormonal control of the oestrous cycle and spermatogenesis. Links physiology to practical timing decisions in AI programmes.

Lesson 3 • Mare Reproductive Anatomy Overview

Identifies ovaries, oviducts, uterus, cervix, and vagina in the mare. Provides anatomical context for insemination site selection and timing.

Lesson 1 • Regulatory and Documentation Requirements

Covers breed registry rules, health certification standards, and record-keeping obligations. Accurate documentation ensures traceability and regulatory compliance.

Lesson 2 • Facility and Equipment Sanitation

Details cleaning, disinfection, and sterilisation of AI equipment and lab surfaces. Proper sanitation prevents spermicidal contamination and pathogen spread.

Lesson 3 • Zoonotic and Venereal Disease Risks

Identifies pathogens transmissible through equine reproductive fluids and contact. Awareness of these risks drives all biosecurity decisions in the AI lab.

Lesson 4 • Animal Handling Safety

Addresses safe restraint techniques and behavioural cues for stallions and mares. Reducing handler injury risk is prerequisite to performing any AI procedure.

Lesson 1 • Artificial Vagina Types and Assembly

Compares open-ended, closed-ended, and Missouri-style artificial vaginas. Correct assembly and temperature setting are critical for sperm viability.

Lesson 2 • Collection Procedure Execution

Step-by-step guidance for deflecting the stallion's penis into the AV during mounting. Correct hand position and timing maximise fraction capture and safety.

Lesson 3 • Phantom Mount Preparation and Use

Covers phantom selection, height adjustment, and surface preparation for stallion mounting. A properly configured phantom ensures safe, repeatable collections.

Lesson 4 • Troubleshooting Collection Problems

Addresses poor libido, incomplete ejaculation, and AV rejection in stallions. Problem-solving skills maintain programme efficiency and animal welfare.

Lesson 1 • Macroscopic Semen Evaluation

Assesses ejaculate volume, colour, pH, and gel fraction separation. These initial observations flag gross abnormalities before microscopic analysis begins.

Lesson 2 • Advanced Sperm Viability Tests

Introduces membrane integrity assays, oxidative stress markers, and DNA fragmentation testing. These tests identify subfertile stallions not detected by standard evaluation.

Lesson 3 • Sperm Morphology Evaluation

Covers staining techniques and classification of primary, secondary, and tertiary defects. Morphology data determines whether an ejaculate meets breeding standards.

Lesson 4 • Sperm Concentration Measurement

Uses haemocytometer and spectrophotometer methods to quantify sperm per millilitre. Accurate concentration data is essential for calculating insemination doses.

Lesson 1 • Extender Composition and Function

Explains the role of buffers, sugars, proteins, and antibiotics in semen extenders. Understanding each component enables rational extender selection for different storage goals.

Lesson 2 • Preparing and Mixing Extenders

Covers reconstitution of commercial extenders and preparation of custom formulations. Precise preparation prevents osmolality errors that damage sperm membranes.

Lesson 3 • Cryoprotectant Addition and Equilibration

Explains glycerol and non-glycerol cryoprotectant addition protocols and equilibration timing. Correct cryoprotectant concentration prevents osmotic and toxic sperm damage.

Lesson 4 • Semen Extension for Cooled Transport

Details dilution ratios, extension temperature, and packaging for cooled semen shipment. Proper extension maintains motility during 24–48-hour transport windows.

Lesson 1 • Straw and Pellet Filling Techniques

Covers 0.5 mL straw filling, sealing, and labelling for cryopreservation. Consistent fill volume and airtight sealing are critical for uniform freezing outcomes.

Lesson 2 • Post-Thaw Evaluation Procedures

Standardises thawing temperature, duration, and immediate motility assessment. Post-thaw evaluation confirms batch quality before straws are released for use.

Lesson 3 • Liquid Nitrogen Handling and Storage

Covers safe liquid nitrogen transfer, tank maintenance, and inventory management. Proper storage prevents catastrophic semen loss from tank failure or nitrogen depletion.

Lesson 4 • Semen Bank Management

Addresses long-term storage logistics, quarantine protocols, and semen release procedures. Systematic bank management maintains genetic resource integrity over decades.

Lesson 1 • Anovulatory and Problem Mare Management

Addresses transitional anoestrus, persistent corpus luteum, and follicular cysts. Recognising and managing these conditions prevents wasted insemination attempts.

Lesson 2 • Oestrous Synchronisation Protocols

Applies progesterone, prostaglandin, and light manipulation to synchronise multiple mares. Synchronisation enables efficient use of cooled or frozen semen shipments.

Lesson 3 • Oestrous Cycle Detection Methods

Covers teasing, behavioural scoring, and ultrasound-based oestrus detection in mares. Reliable oestrus detection is the entry point for all cycle management decisions.

Lesson 4 • Ovulation Induction Agents

Compares hCG, deslorelin, and GnRH analogues for ovulation induction timing and efficacy. Correct agent selection and dosing synchronise ovulation to within a predictable window.

Lesson 1 • Post-Insemination Uterine Management

Addresses post-breeding endometritis diagnosis and treatment with oxytocin and uterine lavage. Prompt treatment of fluid accumulation preserves embryo survival rates.

Lesson 2 • Early Pregnancy Detection by Ultrasound

Teaches detection of the embryonic vesicle at days 14–16 and heartbeat confirmation at day 25. Early detection enables timely twin reduction and repeat breeding decisions.

Lesson 3 • Transcervical Insemination Procedure

Step-by-step technique for passing a pipette through the cervix and depositing semen into the uterine body. Correct pipette placement maximises sperm transport to the oviduct.

Lesson 4 • Deep-Horn Insemination Techniques

Covers rectally guided and endoscope-assisted deep-horn insemination for low-dose frozen semen. Deep-horn deposition compensates for reduced sperm numbers in frozen doses.
