Bruk av alkalisk korn i kraftfôr til drøvtyggere : effekt på vommiljø og fordøyelighet
(Master thesis, 2018)This is a two part thesis consisting of a literature study, and a presentation and evaluation of two experiments on alkaline grain used in concentrates fed to dairy cows. The literature study contains a general presentation ... -
Characterization and expression analysis of the key genes for early development of swim bladder in Atlantic cod
(Master thesis, 2017)Some genes have been proved critical for swim bladder inflation during early stages. Hence, our researches were focused on the investigation into the genetic features of the key genes to early development of Atlantic cod ... -
Chemical changes seen in protein during pelleting : a literature review
(Master thesis, 2017)Pelleting induced changes in protein denaturation with exposure to heat is to milder level. Denaturation of protein showed better digestibility of protein molecule. Change in the secondary structure i.e. alpha helix, beta ... -
Connection between degree of confident behaviour and social motivation in domestick mink
(Master thesis, 2019)Dyrevelferdsmessige utfordringer knyttet til gruppehold av husdyr er et viktig tema i den offentlige debatten, særlig av arter som i naturen lever som solitære rovdyr og med svært territoriale instinkter. Oppdrettsmink er ... -
Degradation and digestion of wheat and legume starch in broiler chickens as affected by pelleting and extrusion
(Master thesis, 2019)Starch is a quantitatively most important source of energy in broiler chicken diets. Diets may contain up to 50% starch on a dry matter basis. Despite high starch contents in the diet, broiler chickens can utilize a variety ... -
Development of alternative baits based on rest raw materials, low-valued and surplus fish for baited gear fishing of Atlantic cod (Gadus morhua)
(Master thesis, 2018)The experiment was conducted to develop the alternative baits from low-valued and surplus fish for pot and longline fishing of Atlantic cod. Minced herring and capelin were used to produce baits for pots with increasing ... -
Dominans av flerårig raigras (lolium perenne L.) i ulike artsblandinger : konsekvenser for avling og fôrkvalitet
(Master thesis, 2018)Flerårig raigras (Lolium perenne L.) er en mye brukt fôrvekst i tempererte områder på grunn av god fôrkvalitet og toleranse for intensiv drift. I Norge har derimot arten ofte ikke blitt inkludert i produksjonen på grunn ... -
Effect of afternoon feeding of particulate limestone on layers' performance, egg and bone quality
(Master thesis, 2018)An experiment was conducted to investigate the effect of split feeding of calcium on the laying performance of hens in the first production cycle, and to study the egg and bone quality of endof-lay hens. A total of 7700 ... -
Effect of air-classified faba bean protein on feed production, physical pellet quality, performance, and protein digestibility in broiler chickens
(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 steam-conditioning and enzymatic treatment on rheological properties of the shrimp feed, formulated with torula yeast (Candida utilis) as a novel feed raw ingredient
(Master thesis, 2018)The use of yeast as an alternative source of protein has been in demand as a novel feed ingredient in shrimp feed nowadays. In order to optimize its use, more research and study is required. The objective of this study was ... -
