A comparative morphological and morphometrical study between the pregnant and non-pregnant female reproductive system of local breed cat (Catus felius)

Abstract

Female reproductive system of cat was used to investigate the morphometrical features of non-pregnant and pregnant animal. Non-pregnant reproductive system was small size, located in the pelvic cavity, while during the pregnancy the system enlarges involved many fetues within uterine horns and occupied the abdominal cavity. The total lengths and weights of reproductive system showed significant differences (P<0.05) between non-pregnancy (length and weight were 14.36±1.32cm and 99.10±0.9g) respectively, and pregnant (Length and weight at 2^nd term of pregnancy were 17.49±2.06cm and 247.11±4.16g respectively). Ovaries revealed significant differences between weight of right ovary at 3^rd term pregnancy (1.80±0.09g) and that of non-pregnant (0.81±0.10g). The uterine tubes of pregnant cat located in abdominal cavity and  a significant differences between the weights of left uterine tube (1.69±0.06g) and right uterine tube (1.80±0.09g) of pregnant and those of non-pregnant cat (left-0=26±0.07) and (right=0.26±0.09). Infundibulum revealed significant differences between the lengths of pregnant cat (right infundibulum=7.37±0.19mm) (left infundibulum=7.41±0.29mm) and that of non-pregnant cat (right infundibulum=5.72±0.12mm) (left infundibulum=5.81±0.7mm). Ampulla revealed significant differences between lengths of pregnant (right ampulla =15.81±0.59mm) (left ampulla =15.41±0.85mm) and that of non-pregnant (right infundibulum=12.19±0.15mm) (left infundibulum=12.17±0.11mm). Uterus of non-pregnant cat comprises of Y-letter shape horns, pinkish colour and located in the pelvic cavity, while in pregnant composed of two huge uterine horns filled with foetuses and occupy the abdominal cavity. The statistical analysis of uterus revealed significant differences between the lengths, diameter and the weight of the pregnant periods and those of non-pregnant period.
