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
