Gross Morphometric Characteristics of Reproductive Organs of Indigenous Non-gravid Cow Originating from Backyard Farms in Brahmanbaria, Bangladesh

Abstract

A study was carried out on the morphometry of reproductive genitalia of twenty indigenous cows available from backyard farms in Brahmanbaria, Bangladesh using standard procedure, with special reference to indigenous cows. Reproductive tracts were collected immediately after slaughter and measurement of the reproductive organs were done immediately after transportation. The average parameter of reproductive organs, length and width were recorded as 2.47±0.08 and 1.85±0.1 cm for right ovary and 2.25±0.09 and 1.62±0.1cm for left ovary; length of right and left uterine horns were 21.38 ± 0.68 and 21.70 ± 0.69 cm; length and width of body of uterus were 3.19±0.06 and 2.49±0.05cm; length and width of cervix were recorded as 5.28±0.1 and 4.61±0.1 cm; length and width of vagina were 19.44±0.4 and 4.73 ± 0.1cm, respectively in indigenous cows. It was observed that right ovary is higher in length and width to that of the left ovary in indigenous cows. This confirms the fact of right ovary being more active than the left one. Moreover, left uterine horn is larger in length to that of the right uterine horn.The genitalia of heifer are smaller compared adult cow. This study provides a baseline for the study of genitalia of indigenous cow breed at Brahmanbaria district in Bangladesh
