Study Notes
Dystocia in Animals
Causes of Dystocia:
- In dogs, the most common cause of dystocia is fetal-maternal disproportion.
- In cats, the most common cause of dystocia is fetal malposition.
- In sheep, factors that can contribute to dystocia include fetal malposition, uterine inertia, and inadequate pelvic size.
- In cows, the most common cause of dystocia during the first stage of parturition is uterine inertia, and during the second stage, it's fetal-maternal disproportion.
- In mares, the most common cause of dystocia during the first stage of parturition is uterine inertia, and during the second stage, it's fetal malposition.
Breed-Specific Dystocia:
- Bulldogs/British bulldogs: 80-90% require surgical delivery of neonates.
- French Bulldogs: 70-80% require surgical delivery of neonates.
- Some breeds of cows (e.g., Holsteins) have a high incidence of dystocia.
Treatment Options:
- Manipulation of the fetus into a normal position or posture.
- Use of oxytocin to increase or decrease contractions.
- Fetotomy: considered ahead of caesarean in monotocous species.
- Elective caesarean: performed when the risk of dystocia is high, such as in breeds with a high incidence of dystocia.
General Information:
- Approximately 2-3% of sow parturitions experience dystocia.
- Feto-maternal disproportion is not common in mares due to the large size of the mare's reproductive tract.
- The size of the fetus in mares is governed by the size of the mare's reproductive tract.
- Twin pregnancies in mares carry a higher risk of dystocia compared to singleton pregnancies (4-6 times higher).
- Abnormal presentation, position, or posture of the fetus during delivery in mares can lead to dystocia and fetal mortality.
- Twins at term are rare in mares, occurring in less than 1% of pregnancies.
- Pelvic fractures are more common in outdoor cats compared to dogs.

Description
Test your knowledge on the causes and assessment of dystocia in cows. Learn about the various presentations of dystocia, the common occurrence of dystocia in heifers bred at an early age, the impact of breed (particularly Holstein), and the use of beef sires resulting in feto-maternal disproportion. Challenge yourself to identify if a calf is deliverable and distinguish between common and less common causes of faulty disposition. Don't forget to brush up on your understanding of twin pregnancies
