Most of the owners normally assess the fertile period on the base of qualitative parameters and mate their bitches on predetermined days. This is the major cause of apparent infertility in bitches. The most reliable assessment for timing of mating is through quantitative assessment through vaginal cytology and progesterone assay. The objective of this study was to compare the outcomes of qualitative and quantitative assessment of fertile period in bitches. Furthermore, the effect of assessment method was studied on fertility (number of pregnant bitches) and prolificity (number of pups in a litter).
This study was conducted on 148 referral cases of bitches brought to Theriogenology Laboratory. The data of qualitative assessment by the owners was collected by a questioner while quantitative assessment was based on vaginal cytology and progesterone assay. Statistical analysis was done using SPSS and logistic regression to compare the fertility (number of pregnancies) and prolificacy (number of pups) among groups.
In qualitative group, only 32% bitches were diagnosed pregnant. In contrast, the quantitative group showed a significantly higher fertility (83%) as compared to qualitative group (P<0.05) with odd ratio of 3 times higher fertility. Similarly, in qualitative group, 58% bitches had litter of 1-4 pups while the rest had a litter ranging in 5-10 pups. In contrast, quantitative group showed significantly (P<0.05) higher prolificity with 79% bitches having a litter of 5-10 with 4 times higher odd ratio. Meanwhile, the percentage of bitches having a smaller litter (1-4 pups) was considerably low (21%). In conclusion, the quantitative assessment of fertile period is more accurate and results in significantly higher fertility and prolificity.
