Documenting Breeding Events and Outcomes

Reproductive records in Kora document actual breeding events. These include pregnancies and births. You record when breeding occurred. Track gestation periods. Document birth outcomes. Link reproductive events to pedigrees. Breeding recommendations provide guidance on what should breed. Reproductive records document what actually bred. This creates permanent breeding history. Supports pedigree verification. Enables breeding program assessment. Tracks reproductive health.

This chapter explains how breeding events are documented. What reproductive information is tracked. How reproductive records integrate with breeding programs.

What are Reproductive Records?

Reproductive records document the complete reproductive cycle from breeding attempt through birth:

• Breeding events: When and how animals bred
• Pregnancy tracking: Gestation monitoring and expected due dates
• Birth records: Offspring delivery, birth details, and outcomes
• Reproductive health: Heat cycles, breeding readiness, complications
• Parent-offspring links: Connecting births to pedigree relationships

Why reproductive records matter:

• Pedigree verification: Document actual breeding creating verifiable lineage proof
• Breeding success tracking: Monitor fertility rates, conception success, birth outcomes
• Reproductive health: Track individual animal reproductive performance
• Birth planning: Prepare for expected births based on pregnancy tracking
• Historical documentation: Create permanent breeding history accessible for years

Example reproductive record lifecycle:

Reproductive records create verifiable breeding history. This spans from conception through birth.

Recording Breeding Events

Breeding events document when and how breeding occurred:

Basic Breeding Event Information:

• Animal: Which animal is breeding (typically female for livestock, either for some species)
• Breeding Date: When breeding occurred
• Breeding Partner Info: Mate identification (registered animal or description)
• Conception Method: How breeding occurred

Conception Methods:

• Natural Breeding: Animals bred naturally through normal reproductive behaviour
• Artificial Insemination (AI): Assisted reproduction using collected semen
• Embryo Transfer: Implanted embryo from donor animal
• Other assisted reproduction: Advanced reproductive techniques

Example breeding event records:

Natural Breeding Event (Cattle):
  Animal: Cow "Beauty"
  Breeding Date: 2024-08-15
  Partner: Bull "Champion" (registered bull in herd)
  Method: Natural breeding
  Location: South Pasture
  Notes: "Single bull with breeding group. Breeding observed by farm staff."

Artificial Insemination Event (Horse):
  Animal: Mare "Windrunner"
  Breeding Date: 2024-07-20
  Partner: Stallion "Lightning Bolt" (semen from registered stallion)
  Method: Artificial Insemination
  Semen Quality: Excellent (60% motility, 80M sperm/ml)

  Notes: "Breeding observed by keepers. Both animals in optimal breeding
          condition. Following breeding recommendation for genetic diversity."

Breeding event documentation establishes conception timeline. Records breeding method used.

Heat Cycle and Breeding Readiness Tracking

For species with oestrus cycles, heat cycle tracking optimises breeding timing:

Heat Cycle Information:

• Heat Start Date: When animal enters oestrus (receptive to breeding)
• Heat End Date: When oestrus period ends
• Cycle Length: Days between heat cycles
• Breeding Readiness Indicators: Physical or behavioural signs

Example heat cycle tracking:

Cow "Prima" - Heat Cycle Documentation:

Cycle 1 (March 2024):
  Heat Start: 2024-03-10
  Heat End: 2024-03-12
  Breeding: Not bred (too early in season)
  Notes: "Clear oestrus signs. Standing heat, increased vocalisation"

Cycle 2 (April 2024):
  Heat Start: 2024-04-01 (22 days after previous cycle)
  Heat End: 2024-04-03
  Breeding: Bred on 2024-04-02 (optimal timing)
  Bull: "Champion"
  Notes: "Inseminated during peak heat for optimal conception timing"

Result: Breeding occurred at optimal time based on documented heat cycle,
        improving conception probability.

Lioness "Nala" - Heat Cycle Documentation (Zoo):

Cycle 1 (June 2024):
  Heat Start: 2024-06-10
  Heat End: 2024-06-14
  Breeding: Not bred (male not interested)
  Notes: "Female showing oestrus behaviour. Male not responsive. Will monitor
          next cycle."

Cycle 2 (August 2024):
  Heat Start: 2024-08-05 (56 days after previous cycle)
  Heat End: 2024-08-09
  Breeding: Bred on 2024-08-06 and 2024-08-07 (multiple matings observed)
  Male: "Simba" (resident male)
  Notes: "Multiple successful matings observed. Both animals showing appropriate
          breeding behaviour. Following conservation breeding programme guidance."

Heat cycle tracking enables precise breeding timing. This maximises conception success across species.

Pregnancy Tracking

Once breeding occurs, pregnancy tracking monitors gestation:

Pregnancy Information:

• Pregnancy Status: Confirmed pregnant or not pregnant
• Expected Due Date: Calculated based on breeding date and species gestation length
• Pregnancy Confirmation Date: When pregnancy verified (ultrasound, blood test, palpation)
• Gestation Notes: Monitoring observations during pregnancy

Species-specific gestation lengths (used for due date calculation):

• Cattle: approximately 283 days (9 months)
• Horses: approximately 340 days (11 months)
• Sheep: approximately 150 days (5 months)
• Elephants: approximately 645 days (22 months)
• Dogs: approximately 63 days (9 weeks)
• Lions: approximately 110 days (3.5 months)
• Parrots: 18-30 days (species-dependent)

Example pregnancy tracking:

Breeding Complications and Challenges

Reproductive records document difficulties when they occur:

Common complications tracked:

• Breeding difficulties: Failure to conceive, multiple breeding attempts required
• Pregnancy complications: Miscarriage, abnormal development, health concerns
• Birth difficulties: Dystocia (difficult birth), assisted delivery required
• Postpartum issues: Retained placenta, mastitis, poor mothering, offspring rejection

Example complication documentation:

Complicated Birth Record - Mare "Windrunner":

Birth Date: 2024-05-10
Expected Due Date: 2024-05-09 (1 day late)

Birth Complications: DYSTOCIA (difficult birth)

Complication Details:
  - Foal malpositioned (one front leg back)
  - Mare in active labour 3 hours without progress
  - Veterinarian called for assistance

Intervention:
  - Veterinarian: Dr Johnson
  - Intervention Time: 2024-05-10 14:30
  - Procedure: Manual repositioning of foal, assisted extraction
  - Duration: 45 minutes intensive intervention

Birth Outcome:
  - Foal delivered alive
  - Foal: Male, "Stormy"
  - Birth Weight: 58 kg
  - Initial Health: Weak but viable
  - Mare Condition: Exhausted but stable

Post-Intervention Care:
  - Foal: Oxygen therapy, intensive monitoring first 24 hours

  - Nursing: Assisted nursing first feeding, foal strengthening

Follow-Up (24 hours):
  - Foal: Significantly improved, nursing independently, standing strongly
  - Mare: Recovering well, normal vital signs, bonding with foal

Outcome: Successful delivery despite complications, both mare and foal healthy
         within 48 hours. Future breeding: Consider earlier veterinary
         monitoring given dystocia history.

Lessons Learned: Mare's future breeding will involve closer monitoring
                 approaching due date, veterinarian on standby for delivery.

Conservation Breeding Complication - Parrot Clutch:

Female: "Jade"

                     will include preventive calcium supplementation starting
                     before breeding season.

Complication documentation informs future breeding management. Shows successful intervention across species. Records lessons learned for future breeding attempts.

Integration with Pedigree Relationships

Reproductive records link to pedigree documentation:

Automatic pedigree creation: When birth recorded with known parents, system can automatically create pedigree relationships linking:

• Sire to Offspring (parent relationship)
• Dam to Offspring (parent relationship)
• Offspring to Both Parents (reciprocal relationships)

Example integrated workflow:

Birth Record Created:
  Date: 2024-06-20
  Dam: Cow "Rain" (Studbook ID: HER-2020-F-431)
  Sire: Bull "Storm" (Studbook ID: HER-2021-M-287)
  Offspring: Calf "Bolt"
  Reproductive Record ID: #2024-156

Pedigree Relationships Automatically Created:
  1. Storm (Parent) → Bolt (Offspring)
     - Confidence: Observed
     - Linked to Reproductive Record #2024-156

  2. Bolt (Offspring) → Storm (Parent)
     - Reciprocal relationship (automatic)
     - Linked to Reproductive Record #2024-156

  3. Rain (Parent) → Bolt (Offspring)
     - Confidence: Observed (birth witnessed)
     - Linked to Reproductive Record #2024-156

  4. Bolt (Offspring) → Rain (Parent)
     - Reciprocal relationship (automatic)
     - Linked to Reproductive Record #2024-156

Result: Birth documentation automatically establishes pedigree with verifiable
        link to reproductive event providing parentage proof.

Conservation Birth Integration:

Birth Record Created:
  Date: 2025-04-18
  Dam: Elephant "Amara" (Studbook ID: BRP-2015-F-018)
  Sire: Elephant "Jabari" (Studbook ID: BRP-2016-M-009)
  Offspring: Calf "Kito"
  Reproductive Record ID: #2025-089
  Conservation Programme: African Elephant EEP

Pedigree Relationships Created:
  - Jabari → Kito (Parent to Offspring, DNA confirmation scheduled)
  - Kito → Jabari (Offspring to Parent, reciprocal)
  - Amara → Kito (Parent to Offspring, Observed - birth witnessed)
  - Kito → Amara (Offspring to Parent, reciprocal)

Studbook Registration:
  - Kito automatically registered in African Elephant EEP studbook
  - Assigned studbook identifier: BRP-2025-M-028
  - Pedigree linked to international studbook database
  - Genetic value assessment scheduled for 6 months

Conservation Impact:
  - Birth contributes to population genetic diversity
  - Follows high-priority breeding recommendation
  - Offspring represents underrepresented bloodline
  - Complete documentation from breeding through birth to pedigree registration

Integration ensures pedigrees reflect documented breeding events. Not just claims. Provides parentage proof through verifiable reproductive records.

Breeding Success Tracking

Reproductive records enable breeding success analysis:

Breeding metrics (derived from reproductive records):

• Conception rate: Percentage of breeding attempts resulting in pregnancy
• Birth success rate: Percentage of pregnancies resulting in live births
• Offspring survival: Percentage of offspring surviving to weaning
• Average litter size: For multi-offspring species
• Individual animal fertility: Reproductive success for specific animals

Example breeding success analysis:

Bull "Champion" - Reproductive Performance (2024 Season):

Breeding Events: 25 cows bred
Confirmed Pregnancies: 22 (88% conception rate)
Births: 21 live calves (95% of pregnancies resulted in live birth)
Stillbirths: 1
Overall Success: 21/25 equals 84% (breeding to live calf)

Analysis: Excellent fertility and breeding performance. Above herd average
          (herd average: 78% breeding to live calf). Bull's genetics and
          reproductive health contributing to strong breeding outcomes.

Recommendation: Continue using Champion for breeding programme. Proven fertility
                and consistent success make him valuable breeding asset.

Conservation Programme Analysis - Parrot Breeding Season 2024:

Breeding Pairs: 8 pairs attempted breeding
Successful Breeding Events: 6 pairs bred successfully (75%)
Confirmed Pregnancies: 6 (100% of breeding events resulted in eggs)
Total Eggs Laid: 24 eggs across 6 clutches
Fertile Eggs: 19 (79% fertility rate)
Hatched Chicks: 16 (84% hatch rate of fertile eggs)
Survived to Fledging: 15 (94% survival rate)
Overall Success: 15 healthy fledged juveniles from 8 breeding pairs

Analysis: Excellent breeding season for endangered parrot programme. High
          fertility rates. Strong parental care resulting in high survival.
          Two pairs that did not breed were new pairs requiring more time for
          pair bonding.

Conservation Impact: 15 new individuals added to captive population representing
                     significant contribution to species recovery. All offspring
                     registered in international studbook. Genetic diversity
                     maintained through careful pair selection.

Recommendations: Continue current breeding pairings for pairs with successful
                 breeding. Allow more time for new pairs to establish bonds
                 before expecting breeding. Maintain current husbandry protocols
                 given excellent success rates.

Success tracking identifies high-performing breeding animals. Reveals reproductive challenges. Enables evidence-based breeding programme improvements across livestock operations and conservation programmes.
