-Different amylase enzymes were identified by analysis of digestive fluid and haemolymph in diapausing and nondiapausing strains of silkworm, Bombyx mori. The diapausing strain showed negligible digestive amylase activity at a pH range of 3-11, while the nondiapausing strain registered strikingly higher amylase activity at pH 9.2. Higher levels of undigested starch was found in the faecal matte...

This study aimed to evaluate the effects of soluble and insoluble non-starch polysaccharides (NSPs) on growth performance, digestive enzyme activity, antioxidant capacity, intestinal flora juvenile GIFT tilapia ( Oreochromis niloticus ). Four isonitrogenous isolipidic experimental diets were formulated, including FM diet (0% NSPs, FM), INSP (5.8% INSP), SNSP (12.2% SNSP), NSP 12.2% SNSP, NSPs)....

This work evaluates the effects of dietary inclusion crude or hydrolysed Arthrospira platensis (Cyanobacteria) biomass on growth, muscle composition, digestive functionality and immune activities in gilthead seabream ( Sparus aurata ) fry (20.32 mg mean body weight). A 40-day feeding trial was conducted, aimed at assessing four experimental diets that included 5 10% (w/w) A. , either hydrolysed...

effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...
