Abstract
Ensuring food and nutrition security in Ethiopia has remained a widespread challenge. In the process of ensuring food security and better livelihood status, underutilized and less exploited food and feed resources should get a prior attention. The objective of this study is utilizing the extensive research outputs on how to use taro corm and leaves accompanied with processing methods for infant food and chicken diet formulation at a good level of nutrient sources. The study was conducted using taro corm for complementary food development and taro leaf for chicken feeding. The analyses undertaken were proximate composition mineral content, anti-nutritional content, functional properties of the food and feed, amino acid, fatty acid profile, β-carotene and other phytochemicals. Crude protein content ranged from 10.49±2.38 to 12.13±2.32 and 25.43±1.92 to 26.25 ±1.53 for taro corm and taro leaf, respectively. Similarly, crude fat in taro corm and taro leaf ranged from 2.61±1.11 to 3.42±0.65, and 5.84±0.16 to 6.37±0.95, respectively. Crude fiber content in taro corm ranged from 2.11±0.26 to 2.80±0.93, and in taro leaf from 3.19±1.98 to 4.60±1.39. The total ash, carbohydrate and energy content in corm were higher than that of taro leaves. However, amino acid composition was higher in the leaf than corm. The optimized complementary food had a proximate content of crude protein; crude fat, total ash, and carbohydrate and energy value were 22.23±0.6, 6.32±0.78, 4.8±0.32 and 56.5±0.46, respectively. The chicken feeding treatments were inclusion of taro leaf meal at 0% (T1), 3% (T2), 5% (T3) and 7% (T4).The nutrient content of chicken meat was determined and differs significantly (P<0.05). In breast chicken muscles the nutrient compositions (protein, fat, ash and vitamin C) were in the order of T4 > T3 > T2 > T1 except the crude fiber content. Therefore, through this study taro leaf and corm were found to be good dietary sources and gave higher nutritional values both for infant complementary food development and chicken feed formulation. Therefore, the findings of this study were found to be very significant for future use of taro leaf in chicken diet and it is believed that this study could give insights for use of taro flour in industry level for making complementary foods to mitigate household food insecurity and malnutrition in Ethiopia.
