Hypothesis
What are the demographic parameters, such as survival and fecundity, of roaming dogs in Jaipur, India?
Conclusion
The study suggests that careful recording of demographic parameters can help predict the effectiveness of population control methods for roaming dogs.
Supporting Evidence
- 47.5% of female dogs become pregnant each year.
- Adult annual survival of spayed females is estimated at 70%.
- The average litter size in Jaipur is 5.6, leading to an average fecundity of 1.33.
Takeaway
The study found that about half of the female dogs in Jaipur get pregnant each year, and spayed females live about 3.8 years.
Methodology
Data was collected from over 25,000 spayed females caught for spaying from 1995 to 2006, and survival estimates were derived from recapture data of 62 spayed females.
Potential Biases
Potential bias in survival estimates due to missed ear notches and varying capture efforts.
Limitations
The study may not account for all demographic variations in the roaming dog population.
Participant Demographics
The study focused on female roaming dogs in Jaipur, India.
