| rhinopneumonitis | killed vx at 5, 7, and 9 months |
| Puberty | 18 months |
| type of estrus cycle | seasonally polyestrous |
| Transisitonal heat | the first heat cycle of the breeding season |
| Breeding season | Feb-Oct |
| length of estrus | 21 days |
| standing heat | 5-7 |
| signs of heat | 1.winks vuvlar lips 2. wide rear stance 3.frequent urination 4. raised, laterally deflected tail 5. accepts stallion |
| gestation | 320-360 days |
| pregnancy confirmation | 1. rectal palpation- day 30 2. ultrasound- days 14 3. serum progesterom assay -day 14+ |
