ABSTRACT
32 weeks old laying hens were used in this study. The birds were divided into 4 groups: the control group (group I) fed with basal diet and experimental groups II, III and IV fed with basal diet supplemented by appropriately 2, 5 and 10% addition of amaranth grain. No statistically relevant changes in the haemoglobin level and the haematocrit volume in the birds’ blood were noted during the study. The erythrocyte count was diversified and ranged between 2.7 (group III) and 3.1 x 1012 l-1(group IV). As compared to the control group, a statistically significant difference in the total cholesterol level was noted for hens in group II. Falling tendency was observed for groups fed with diet supplemented by a larger share of amaranth grain, i.e. 5 and 10 % share. The largest fall of the LDL fraction of cholesterol, by appropriately 45.6 and 52.3 %, was shown for groups fed with 5 and 10% addition of amaranth grain (group III and IV). The level of HDL fraction of cholesterol was higher in the experimental groups, fluctuating around the level of 0.24-0.36 mmol l-1, as compared to the control group with the level of 0.22 mmol l-1The triglycerides content in respective groups of birds fed with addition of amaranth grain was significantly different (p≤0.05) as compared to the control group. The largest fall of triglycerides content was noted for group IV. The ALT activity in groups fed with 2 and 10% addition of amaranthus grain was higher in comparison to the control group, reaching respectively 44.8 and 36.9 IU l-1, (p≤0.05) for experimental groups and 27.5 IU l-1 for the control group. The ALT activity in the group fed with 5% addition of grain was comparable to the one noted for the control group, i.e. 20.5 IU l-1. The highest level of aminotransferase (AST) activity, i.e. 466.14IU l-1 , was observed for the group fed with the largest (10%) addition of amaranth grain and constituted difference that was statistically significant in comparison to the control group level, i.e. 373.71 IU l-1, p ≤ 0.05. Elevated levels of glucose and protein were observed in experimental groups as compared to the control group.
Key words: amaranth, blood, lipids, laying hens.
