Air-classified faba bean protein fraction as a substitute to soybean meal in pelleted and extruded broiler diets
Itani, Khaled; Hansen, Jon Øvrum; Kierończyk, Bartosz; Benzertiha, Abdelbasset; Kurk, Ahmet Eralp; Ånestad, Ragnhild; Schüller, Reidar Barfod; Mydland, Liv Torunn; Svihus, Birger; Øverland, Margareth (Peer reviewed; Journal article, 2021) -
Eating patterns of broiler chickens fed insoluble grit, and its effect on intake variation, retention time, performance and gizzard development
Itani, Khaled (Master thesis, 2015-07-02)In a field trial, the current study tested the effects of insoluble granite grit stones supplemented to broiler chickens on growth performance and gizzard stimulation. Particle size distribution and variation in the amount ... -
Effect of air-classified faba bean protein on feed production, physical pellet quality, performance, and protein digestibility in broiler chickens
Kurk, Ahmet Eralp (Master thesis, 2019)Faba bean seed is a good source of crude protein (CP) (293.06 g/kg DM), however soybean meal (SBM) is the dominant protein source in broiler chicken diets. With air classification technique, faba bean seeds can separate ... -
Effect of crop retention time and acidification of the feed on phytase efficacy in broiler chickens
Kristoffersen, Siril; Itani, Khaled; Benzertiha, Abdelbasset; Kierończyk, Bartosz; Kjos, Nils Petter; Svihus, Birger (Peer reviewed; Journal article, 2021) -
Feed processing and structural components affect starch digestion dynamics in broiler chickens
Itani, Khaled; Svihus, Birger (Peer reviewed; Journal article, 2019)1. A 2 × 2 factorial design was used to test the hypothesis that impaired intestinal starch digestibility is attributable to rapid passage of digesta from the gizzard to the intestine, and that, compared to steam pelleting, ... -
Interactions between starch source and gelatinisation degree on performance and small intestinal digestion in broiler chickens
Itani, Khaled; Hansen, Jon Øvrum; Kierończyk, Bartosz; Benzertiha, Abdelbasset; Kurk, P.P.; Ånestad, Ragnhild; Sundby, Frank; Mydland, Liv Torunn; Øverland, Margareth; Svihus, Birger (Peer reviewed; Journal article, 2021) -
Intestinal Passage and Its Relation to Digestive Processes
Svihus, Birger; Itani, Khaled (Peer reviewed; Journal article, 2019)Despite an effective nutrient retention, impaired digestibility is frequently observed. This review aims to give an overview of retention time of material through the digestive tract in an attempt to reveal mechanisms ... -
Performance and digestive function of broiler chickens given grit in the diet
Svihus, Birger; Itani, Khaled; Borg, Knut; Larsson, Ellen Cecilia; Ao, Rihan; Sudubilige, A; Fuerjiafu, Biemujiafu; Liu, Huan; Hetland, Harald; Sanson, G; Kieronczyk, B; Rawski, M; Jozefiak, D (Peer reviewed; Journal article, 2017)1. A series of experiments were carried out to study the effect of grit on broiler performance, gizzard development and fate of grit in the digestive tract. 2. In Experiment 1, performance, gizzard weight and content of ... -
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 ... -
Varying starch to fat ratios in pelleted diets: I. Effects on nutrient digestibility and production performance in Eimeria-challenged broiler chickens
Itani, Khaled; Granstad, Silje; Kaldhusdal, Magne; Mydland, Liv Torunn; Svihus, Birger (Peer reviewed; Journal article, 2020) -
Varying starch to fat ratios in pelleted diets: II. Effects on intestinal histomorphometry, Clostridium perfringens and short-chain fatty acids in Eimeria-challenged broiler chickens
Granstad, Silje; Itani, Khaled; Benestad, Sylvie L.; Øines, Øivind; Svihus, Birger; Kaldhusdal, Magne (Peer reviewed; Journal article, 2020)
