Abstract
It is an orthodox idea that teff has highest content of iron among the majority of cereal-based
diet, which provides almost the entire staple food consumed in Ethiopia. However, now a day it
is proven that it is due to soil contamination. Thus, these leads to two distinctive ideas on the
contaminant iron bioavailability. The current study was, then, initiated with the objective of
evaluating effect of different soil contamination on rat of hemoglobin regeneration efficiency.
The invivo iron bioavailability of the uncontaminated teff, vertisol contaminated teff, and
cambisol contaminated teff were analyzed and compared against the standard ferrous sulfate
group. There was no significant deference in total food and iron intake, weight gain, feed
efficiency ratio, initial and final hemoglobin, hemoglobin gain, hemoglobin regeneration
efficiency between and among treatment and control groups (P<0.05). However, there was a
significant difference in final hemoglobin, hemoglobin gain, and hemoglobin regeneration
efficiency between teff and control group. The hemoglobin regeneration efficiency of control
group was about 12% higher than teff group. The relative biological value of teff, vertisol and
cambisol groups were 79.47%, 86.91% and 86.24% (P<0.05) respectively. The 6.77% and 7.44%
of relative biological value and 3.97% and 4.31% of hemoglobin regeneration efficiency
enhancements were observed due to 35mg/kg of extrinsic iron for vertisol and cambisol groups
respectively. In summary, the current study demonstrates that intrinsic iron originated from teff
has a good relative biological value, contamination of teff with both varieties of soil considerably
improves the iron bioavailability; thus, contaminant iron has a good nutritional interest, and soil
(vertisol and cambisol) contamination do not interfere with the intrinsic iron bioavailability.
