Four isonitrogenous (gross protein content 32%) and isoenergetic (gross energy content 4 080 kcal/kg) diets were prepared by extrusion to investigate the effects of different cereal grains (barley ?di...
Intensive rearing of the nase Chondrostoma nasus (L.) larvae using dry starter feeds and natural diet under controlled conditions
nase larvae feeding
2015/6/1
We performed intensive rearing of larvae of the nase Chondrostoma nasus (L.) in a feeding experiment until 21 days from the initiation of exogenous nutrition under laboratory conditions at a temperatu...
Iodine content in bulk feeds in western and southern bohemia
pasture herbage hay grass silage
2015/6/1
In 1997?001 a total of 304 samples of bulk feeds were analysed. Iodine was determined spectrophotometrically by Sandell and Kolthoff抯 method (Bedn狲 et al., 1964). The highest content of iodine was det...
