The effect of different krill meals fed to laboratory rats on their blood indices.
1. In 102 laboratory rats fed with (a) the krill standardized meal, (b) the krill meal with low chitin content, (c) the casein diet with D,L-methionine, (d) the casein diet with D,L-methionine supplemented with the krill carapace meal, (e) the casein diet with D,L-methionine supplemented with ash from the krill standardized meal and (f) the control diet--"Murigran" standard pelleted feed; the different blood indices were investigated. 2. The mean values of following indices: the number of erythrocytes and leucocytes, the percentage of leucocytes, the corpuscular haemoglobin concentration and red blood cell diameter were similar in all experimental and control groups. 3. The mean values of haematocrit and haemoglobin levels, the mean corpuscular thickness and volume were lower in rats fed with the casein diet with D,L-methionine supplemented with the krill carapace meal than in other groups. 4. All kinds of investigated indices were similar in rats fed with krill meal with low chitin contents, whose parents received the standardized krill meal and no sex differences have been shown here.
