چکیده انگلیسی
This study was based on a convenience-sampling questionnaire study of pedigree cat breeding in the UK. Data were collated for the births of 1056 litters from 14 different pedigree breeds and 942 different households. Significant relationships between various outcomes and relevant predictors were assessed by multiple linear regression or logistic regression as appropriate. The overall mean gestation length of 65.1 days varied significantly between the breeds (PÂ <Â 0.0001), and larger litter sizes were associated with shorter gestation lengths (PÂ =Â 0.04). The mean litter size of 4.6 kittens also varied significantly according to breed (PÂ <Â 0.0001). The weight of kittens born alive (overall mean 93.5Â g) increased with longer gestation lengths (PÂ =Â 0.0003), decreased with larger litter sizes (PÂ <Â 0.0001) and varied between the breeds (PÂ <Â 0.0001). A total of 8.0% of pregnancies resulted in a caesarean section, with a higher risk associated with smaller litter sizes (PÂ =Â 0.002). Although the frequency of caesarean sections varied from 0 to 18.5% between individual breeds, breed itself was not shown to have a significant independent effect on this likelihood. A mean of 7.2% of all the kittens were stillborn, which varied according to breed (PÂ =Â 0.0003), and the risk of a stillborn kitten increased with litter size (PÂ =Â 0.0001), and with the presence of congenital defects in the litter (PÂ =Â 0.0002). The mean kitten mortality between birth and 8 weeks of age was 9.1%, and the majority of these occurred in the first week of life. Parturition intervals varied widely. The duration of first stage of labour was less than 2Â h in 82.9% of cats. The interval between the birth of the first and last kitten was less than 6Â h in 85.7%, but more than 48Â h in three cats. A maximum of 48Â h was recorded between the births of individual kittens in unassisted deliveries.
