Abstract

In the present study, the 3-year breeding behavior of the parent dogs in a Pomeranian farm was followed, and the effects of season and insemination method on their reproductive performance were investigated. The gestation period was 62.4 days, the age at which sexual maturity is reached was 404.4 days and the average period between two estruses was found as 205.2 days. The mean number of offspring, and the mean number of male and female puppies were found as 3.4, 2.15 and 1.4 respectively. The stillbirth rate was found as 1.4% and the survival rate to 1 year was 83.3%. The pregnancy rate, the average number of female puppies, the number of stillbirths and the total number of offspring were found to be similar in naturally and artificially inseminated females (P&gt;0.05). While 47.6% of estruses were seen in the spring-summer months, 52.4% were seen in the autumn-winter months (P&gt;0.05). The mating season did not affect the number of female offspring, the stillbirth rate or the total number of offspring (P&gt;0.05). However, when compared to the spring-summer months, the mortality rate of females up to 1 year of age showing estrus in the autumn-winter season was found to be significantly higher (P&lt;0.01).

Highlights

The interest in owning dogs, which started as a hobby cost of feeding and care compared to farm animals for people, has become even more popular with the make it desirable to breed these animals
In order to determine the effect of the breeding season on the number of offspring born, bitches mated in spring and summer months were assigned into the first group (n:10) and those that mated in autumn and winter months were assigned into the second group (n:11) and the number of offspring, the number of female puppies, stillbirth rates and the number of offspring that died after less than a year were noted down
The age of first use in mating was found as 404.4 days, the average period between two estruses was found as 205.2 days, the average number of offspring was found as 3.4, the average number of male offspring was found as 2.15, the average number of female puppies was found as 1.4, the stillbirth rate was found as 1.4% and death rate up to 1 year 16.7%

Summary

Introduction

The interest in owning dogs, which started as a hobby cost of feeding and care compared to farm animals for people, has become even more popular with the make it desirable to breed these animals. The decrease of socializing and increasing demand for high-priced purebred dogs as the increase in the time spent at home during the pets, dog owners today often consult veterinarians for pandemic have resulted in changes in human solutions for fertility problems The increasing dog population and keeping pets has a protective effect against the developing canine medicine reveal the need for psychological effects of the pandemic (Akalın et al, detailed knowledge of the reproductive physiology and 2020). The increasing demand for dog ownership has endocrinology of dog breeds. Detailed elucidation of increased the number of dog producing enterprises the reproduction of both male and female dogs will both in the world and in our country.
