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 ... -
The effect of harvest time of timothy on digestibility in equine with in sacco and in vitro methods
(Master thesis, 2022)The objective of the present thesis was to investigate how harvest time influence digestibility in horses, in addition, to compare three different methods evaluating digestibility. Timothy grass was harvested eight times ... -
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 ... -
Effect of intermittent feeding and structural components on performance and digestive tract for broiler chickens
(Master thesis, 2014-07-31)An experiment was conducted to study the effect of a diet with high structural component on the performance of ad lib and intermittently-fed broiler chickens; whether the supplemented enzymes had effect on ileal viscosity ... -
The effect of Jersey in Norwegian dairy production
(Master thesis, 2022)Alterations in customer demands has the latest years increased the aggregate demand for milk fat from Norwegian dairy production. To encourage farmers to produce more milk fat, the premium for fat has been increased to ... -
Effect of microoganisms on gluten quality in wheat
(Master thesis, 2017)Food security is a current issue of both domestic and international concern. Faced with a growing population and the increased food demands it entails, the Norwegian government has recently renewed its commitment to increase ... -
Effect of nutritional level of omega-3 fatty acids on growth and health related parameters of Atlantic salmon rared in fresh water
(Master thesis, 2014-02-19)Fish are the main supplier, in the human food basket, of the health beneficial n-3 highly unsaturated fatty acids (HUFA). Fish oil (FO) has traditionally been used as the dominating lipid component in fish feed. However, ... -
