Why Control Timing of Parturition?
Herds
- Improves supervision to ensure the farmer can be around at the time of parturition.
- Reduces the incidence of parturition at night/weekends which is socially undesirable.
- Aids cross fostering between litters.
- Tightens the calving interval in cattle.
Individuals
- Maternal emergrncy such as abnormal foetal position, bone fracture of the pelvis etc.
- Foetal abnormality, or an oversized foetus.
Disadvantages of Parturition Induction
- Timing may not be absolutely perfect, there is considerable variation in the timing of drug action and effect.
- Premature delivery of small, immature offspring.
- Increased incidence of retained placenta.
- Pharmacological induction can only be used commercially in cattle and pigs. Induction in other species is used only to overcome birth associated problems.
