چکیده
Gonadal and extragonadal sperm reserves were determined in twenty sexually matured domesticated African greater cane rats. Mean (+/-SD) sperm numbers in testes and epididymides were 150.40+/-12.93x10(9) and 259.33+/-13.68x10(9), respectively. The mean epididymal distribution of spermatozoa was found as follows: 67.53+/-12.43x10(9) in caput, 89.10+/-13.20x10(9) in corpus, and 102.70 +/-13.71x10(9) in cauda. This study provides baseline data essential for effective selection of male cane rats for breeding purposes.

Comparative morphometric analysis of the gastrointestinal tract of the captive greater cane rat (Thryonomys swinderianus) and African giant pouched rat (Cricetomys gambianus).
The greater cane rats (Thryonomys swinderianus) and African giant pouched rats (Cricetomys gambianus) are among the largest rodents in Africa, undergoing domestications for meat and research purposes. The aim of this study was to explore whether there are any quantitative anatomical gastrointestinal adaptations associated with their omnivorous or herbivorous diets. In the African giant rat, the...

The structure and morphometry of the epididymis in the greater cane rat were studied in this work. In assessing the morphology and characterising the morphometric values, a total of 15 adult male greater cane rats, bred and raised in captivity, were used. All the animals had brownish perineal staining, which was taken as index of sexual maturity in male cane rats, and they were maintained on el...

Introduction: Sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. The purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. Methods: Twelve grasscutters comprising of 6 males and 6 females were used in this study. Each b...

Background: The aim of this study was to investigate the effects of hydroalcoholic extract of lepidium sativum(LS) on sperm parameters in adult rat. Materials and Methods: Male adult rats were divided into three groups: control group (n=5) received normal salin; group2: received 200 L.S extract; group3: received 400 LS extract. All groups were treated for 21 days. Evaluations were made by hysto...

In this study, the structures of penises of eight sexually mature male greater cane rats were examined at both macroscopic and histological levels. Each animal was sacrificed after anaesthesia with ether and then dissected open with the penis exposed from its root. The penises were first grossly examined, measured, and then prepared for histological examination. From this study it was observed ...
