“…(data not shown). Many studies have explored inbreeding in dog breeds, showing different average value of the pedigree coefficient inbreeding both within and amongst breeds, which also varies across countries (Różańska-Zawieja et al 2013). The results presented in this paper suggest that this population of Basset Hound had a good level of genetic variability.…”

“…In some Italian breeds F value ranged from 2.27% in Lagotto Romagnolo (Sabbioni et al 2008), 6.29% in Bracco Italiano dog breed (Cecchi et al 2013) to 10.81% in Bolognese dog breed (Sabbioni et al 2007). On the other hand, values of inbreeding smaller than 1% were reported by Cecchi et al (2009) in an Italian colony of guide dogs (0.45% in German Shepherd dogs, 0.38% in Labrador dogs and 0.49% for Golden Retriever dogs) and by Różańska -Zawieja et al (2013) in the Hovawart dogs (0.26-0.31%).…”

The influence of inbreeding depression on phenotypic traits of a Basset Hound dog Italian population was evaluated. Moreover this paper reports the first results of a survey on morphological traits and analyse the genetic variability of the population using genealogical information. The following traits were studied: height at withers, height of chest, depth of chest, body length, length at rump, ischiatic width of rump, circumference of chest, circumference of cannon, length of ear, and length of nose. The inbreeding coefficient (F) of each dog was computed by genealogical data. Traits were taken from 75 adult (mean age 2.17±1.545 years) dogs (36 males and 39 females) belonging to 19 different Italian farms. A linear regression of each trait on inbreeding coefficient was used to estimate inbreeding depression. ANOVA was used to test the differences in morphological traits between the sexes, among breeders and among animals with different F level. Despite the good level of genetic variability and the low coefficients of inbreeding observed in the population, a significant weakly effect of inbreeding on the depth of chest was observed. In addition, the present study revealed no significant differences in morphological traits between sexes and among farms.

The aim of the study was to analyze retrospectively the influence of inbreeding on fertility traits in five dog breeds: German Shepherd dog (GSD), Golden (GR) and Labrador (LR) Retrievers, Beagle and the Tatra Shepherd dog (TSD). The data were 436 litters, with the total of 2560 puppies: 1307 males and 1206 females. The parents of the litters were 163 dogs and 228 bitches. For each litter the litter size, number of male and female puppies, sex ratio, and sex difference were calculated. The fixed effects of breed, of litter birth year and linear regression coefficients on litter and parents’ inbreeding were included in the linear model for litter traits. The correlations between litter traits and litter parents’ inbreeding were also estimated. The average litter size was 5.87 (± 2.53) for all breeds. GSD had the smallest average litter size differences in years and the lowest fluctuations of sex ratio with litter size. In other dog breeds those differences were much bigger. The difference between the number of male and female offspring in a litter depended on the breed. The lowest percentage of inbred parents was found for LR, and the highest for TSD. Mating non-inbred animals, in most cases also unrelated, was frequent in all breeds. The inbreeding level of parents had significant influence on the litter traits only for TSD. For the Beagles low, positive and significant correlation between the number of female offspring in a litter and the dam’s inbreeding level and the sex ratio below 0.5 suggests sex ratio disturbance. The correlation coefficients between litter inbreeding and litter size for majority of examined dog breeds were positive but not significant. The conclusion is that in Poland at first obligatory monitoring of the inbreeding level for all breeds should be applied.
