Productive Performance and Carcass Characteristics of Captive Grasscutters (Thryonomys swinderianus) Fed Concentrate Diets Containing Varying Levels of Guinea Grass
An experiment was conducted to evaluate the productive performance and carcass characteristics of three groups of growing grasscutters fed home-made concentrate diets. The objective was to assess the feeding values of the diets. The diets were labelled 0% grass diet, 7.5% grass diet and 15% grass dietand respectively contained 0, 7.5 and 15% guinea grass, Panicum maximum. The completely randomi...
متن کاملPerformance of Growing Grasscutters (Thryonomys swinderianus) Fed Cassava-Based Diets with Graded Protein Levels
Forages and crop residues are inexpensive and easily available feedstuffs for feeding grasscutters in captivity. These feedstuffs are nutritionally poor, not balanced for optimum performance and, therefore, required supplementation. Protein requirement of growing grasscutters was determined using thirty two 10-weeks old male grasscutters of equal weights. The grasscutters were separated into fo...
متن کاملFiber Composition of the Grasscutter (Thryonomys swinderianus, Temminck 1827) Thigh Muscle: An Enzyme-histochemical Study
The aim of this study was to describe de fiber composition in the thigh muscles of grass cutter (Thryonomys swinderianus, Temminck 1827). Ten 4 to 6-month-old (3 to 4 kg) male grasscutter were used in this study. Eleven skeletal muscles of the thigh [M. biceps femoris (BF), M. rectus femoris (RF), M. vastus lateralis (VL), M. vastus medialis (VM), M. tensor fasciae latae (TFL), M. semitendinosu...
متن کاملGonadal and extragonadal sperm reserves of the domesticated adult African greater cane rat (Thryonomys swinderianus).
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(...
متن کاملSex Differences in the Cerebellum and its Correlates with Some Body Traits in the African Grasscutter (Thryonomys swinderianus – Temminck, 1827): Morphometric Study
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 br...
