The Role of Fiber in Energy Balance
Hervik, Astrid Kolderup; Svihus, Birger (Peer reviewed; Journal article, 2019)Excessive energy intake is linked with obesity and subsequent diet-related health problems, and it is therefore a major nutritional challenge. Compared with the digestible carbohydrates starch and sugars, fiber has a low ... -
Starch digestion dynamics in broiler chickens as affected by structural components, starch properties and level of inclusion
Itani, Khaled (PhD Thesis;2019: 57, Doctoral thesis, 2019)Quantitatively, starch is the most important component and the major energy source in poultry diets. Although it is commonly believed that the broiler chicken has a large capacity to digest starch, numerous studies have ... -
Starch Digestion in Broiler Chickens: A Literature Study and an In vitro Comparison with Pigs
Talibov, Sanan (Master thesis, 2017)Starch is a quantitatively important source of energy in poultry diets. Despite high loads of starch in the diet, poultry species can utilize a variety of starch sources very efficiently. Pancreatic α-amylase is the major ... -
The effect of granite grit on broiler chickens performance and gizzard development
Larsson, Ellen Cecilia (Master thesis, 2016-08-16)For å undersøke effekten kråsstein på slaktekyllingens ytelse og kråsutvikling, ble en omfattende studie utført ved Senter for Husdyrforsøk, ved Norges Miljø- og Biovitenskapelige Universitet i Ås, Norge. 252 dag gamle ... -
The effect of gritstone supplementation on performance and digestion in broiler chickens
Borg, Kari (Master thesis, 2016-08-18)A study was conducted to investigate the effect of grit supplementation for broiler chickens’ performance and digestion. Three field trials were performed to observe the effect of insoluble quartz grit under commercial ... -
The effect of reduced feed pH, phytase addition and their interaction on mineral utilization in pigs
Kristoffersen, Siril; Gjefsen, Torger; Svihus, Birger; Kjos, Nils Petter (Peer reviewed; Journal article, 2021) -
The effect of the grit stone on feed passage rate in broiler chickens
Fuerjiafu, Biemujiafu (Master thesis, 2016-08-18)An experiment was carried out to test the hypothesis that feeding grit to broiler chickens would slower the passage rate of the feed throughout the digestive tract. At the same time, the effect of grit on the performance ... -
The effects of marble grit supplementation on the performance of broiler chicken
Liu, Huan (Master thesis, 2016-08-18)A trial was carried out to investigate the effects of both insoluble and soluble grits supplemented to broiler chicken on the growth performance and gizzard stimulation. Particle size distribution of excreta, grit passage, ... -
The performance of Quantum blue phytase at different pH levels using wheat based diet in an in vitro simulation of poultry crop
Tao, Nala (Master thesis, 2018)An experiment was carried out to investigate the impact of different dietary pH levels as stimulate the efficacy of Quantum blue phytase in an in vitro simulation of poultry crop. The experiment consisted of two parts; an ... -
