Non-Genetic Factors Affecting Grasscutter Production Traits. 1. Growth Traits
This study was conducted at the grasscutter section of the University of Education, Winneba, Ghana, to estimate effects of non-genetic factors on growth traits. Data consisted of records of 502 kids born from 136 does and 40 sires from 2006 to 2010. Feed intake increased (P<0.01) with increasing parity and years, whilst feed efficiency declined (P<0.01) with years. Animals consumed less (P<0.01...
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 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 b...

متن کاملGenetic and Non-genetic Factors Affecting Some Reproduction Traits in Tharparkar Cattle
A total of 1385 lactation records of Tharparkar cattle collected from LRS Chandan, Jaisalmer spreading over a period of 33 years were utilized to assess the effects of period and season of birth/calving on age at first calving, calving interval and service period and also studied effect of parity on calving interval and service period. The least-squares means were 1821.86 ± 37.022 days, 414.16 ...
