Curles, Erica Ann (Master thesis, 2018)True digestibility of feeds and feed ingredients is difficult to measure in fish, partially due to methodological challenges in quantifying endogenous losses that are mixed with undigested materials originating from the ... -
Evaluating retch wire screen as a new tool for feces collection in digestibility assessment in fish: the impact of nutrient leaching on apparent digestibility of fishmeal, soybean meal and rapeseed meal diets in rainbow trout (Oncorhynchus mykiss)
Shomorin, Oluwaseun George (Master thesis, 2017)The study was carried out to evaluate the retch wire screen as a potential tool for collecting feces from water, by comparing its apparent digestibility estimates with that of the conventional stripping method. The retch ... -
Evaluation of apparent nutrient digestibility in Atlantic salmon fed diets with differently processed faba bean
Alinasabhematabadi, Leili (Master thesis, 2019-09-30)This study was conducted to evaluate the apparent digestibility coefficients (ADC) of three different diets with faba bean in Atlantic salmon (Salmo salar). A basal diet was prepared with fish meal, soy protein concentrate ... -
