Effect of different enzymes on compacting and physical quality characteristics of torula yeast (Candida utilis)
(Master thesis, 2017)The purpose of this study was to investigate the reaction between the yeast materials derived from Candida utilis (CU) and different enzymes, and to evaluate their interaction on physical pellet quality. In order to evaluate ... -
Effect of feeding supplementary diets containing soybeans and moringa leaves on growth and fillet quality of Nile tilapia (Oreochromis niloticus), and comparison of growth and fillet quality between Nile tilapia (O. niloticus) and Wami River tilapia (O. urolepis hornorum)
(Master thesis, 2014-08-13)The primary object of this study is to compare effects of various diets and tilapia species on growth performance and fillet quality. The secondary objective is to evaluate which diet could serve as a good alternative for ... -
Effect of hammer milling, roller milling and pelleting on technical and nutritive value of barley for ruminants
(Master thesis, 2014-09-24)Barley is world’s fourth grain with respect to its production. To understand its characteristics and effects of different processing methods upon its utilization by ruminants, a comprehensive literature review was conducted ... -
Effect of inclusion zeolite as grit in commercial pelleted diet on caged broiler's growth performance, gizzard parameters and excreta size distributions
(Master thesis, 2016-08-18)The purpose of this experiment is to determine effects of inclusion zeolite as grit in modern caged broilers. A total of 252 day-old male broilers arrived in pens and were reared only commercial starter pellets and water ... -
Effect of intensive calf rearing on average daily gain in the pre-weaning period and first lactation milk yield
(Master thesis, 2010-12-17)Abstract Most studies on intensive rearing of dairy calves in the pre-weaning period have revealed a positive impact on early and later life performance, but have struggled to reveal statistically significant results. On ... -
