“…Raw A. hypochondriacus grain can effectively replace maize in broiler starter diets at a rate of 200 g/kg, and this can be increased to 400 g/kg if the grain is extruded and steam pelleted (Kabuage, 1996). The poor performance of monogastric animals fed grain amaranth diets has been attributed to anti-nutritional factors in the raw grain (Cheeke & Bronson, 1980;Pond et al, 1991;Kabuage, 1996). Apparently, the raw grain does not biologically exhibit the protein quality suggested by its amino acid composition (Bressani, 1988).…”

Two feeding trials with broilers (1-31 days of age) were carried out to determine the effect of fortifying grain amaranth based diets with lysine, methionine, casein and ethylene diamine tetra acetate (EDTA) on broiler performance, amino acid availability, plasma amino acid concentrations and nitrogen and mineral retention. In Trial 1, lysine, lysine plus methionine and casein were separately included in six diets containing either 400 g/kg raw or 600 g/kg extruded amaranth. Additionally, one 400 g/kg raw and one 600 g/kg extruded amaranth diets were not fortified. The eight diets were compared to a maize-soyabean meal diet as the control. Chicks on the 600 g/kg extruded amaranth diet with casein gave similar body weights at 31 days of age to those on the control diet. Feed intake and nitrogen retention were similar in the control and the extruded amaranth diets. The availability of amino acids was the highest in the chicks on the control diet. The lack of response to lysine, or lysine and methionine inclusions indicated that these amino acids were not limiting to growth in amaranth diets. In Trial 2, three diets contained 400 g/kg raw amaranth, and another three, 400 g/kg extruded amaranth. Two diets in each group were fortified with either disodium EDTA or casein, while the third was unfortified. Casein inclusion resulted in higher body weights at 31 days of age, but did not affect the plasma concentration of essential amino acids. Dietary EDTA did not enhance mineral retention in the body or the concentration of minerals in plasma. It was evident from both trials that the fortification of amaranth diets with casein improved chick performance and the availability of some amino acids.

The projected growth in global food demand has resulted in increased attention towards underutilized crops with the potential to improve global food security and ability to mitigate adverse effects of climate changes. Changing consumer demands in favour of more nutritiously balanced and organically grown crops have added to the interest in species such as amaranth. Promoting the consumption and cultivation of amaranth could be valuable due to its unique nutrient composition and inherent tolerance of drought and other stress factors. Due to current and predicted effects of climate changes, these attributes are becoming increasingly important. Amaranth is a source of high quality protein, as well as dietary fibre and lipids rich in unsaturated fatty acids. The seeds contain desirable levels of minerals, vitamins for human diets, in addition to other bioactive components such as phytosterols, squalene, fagopyritols, saponins and polyphenols. Amaranth is currently in demand by specific consumer groups, such as high-performance athletes, malnourished children, and people suffering from diabetes and coeliac disease. Even so, there are few detailed analyses available concerning the potential for using amaranth to improve and support agricultural productivity in developing countries. The present review has assessed the promotion and improvement of amaranth production in East Africa to hold subtstantial potential for benefitting small-holder farmers in Africa, by providing a stable source of income and food for subsistence farmers, while also mitigating the impact of climate change through the prospect of supporting the establishment of food and nutritional security.

“…However, amaranth has been shown to have some growth inhibiting factors that can be reduced by exposure to heat. In an experiment where rats were placed on amaranth grains with different pretreatment (raw, dry-heating, moistheating, soaking in water), only the group fed on moist heat grains gained weight over the 14-day of the experiment, other rats gained weight in the first 6 days and lost it afterward (Pond et al 1991). Pre-heated Amaranth grains can be used as a feed ingredient for broilers.…”

The burden of malnutrition in Africa calls for deeper exploration of underutilized species which are rich in nutrients and have the potential to reduce food and nutrition insecurity. The common staple crops are not able to meet daily requirements for both macro-and micro-nutrients. In order to lessen this burden; protein, calorie and micronutrient deficiencies must be properly addressed for optimal growth and development to be attained. African indigenous underutilized vegetables can play a significant role in the food security of vulnerable groups like under-five children and women in both urban and rural settings. The potential of grain amaranth in meeting the nutrition needs of humans has remained a subject of interest in scientific research. Amaranth is considered one of the most commonly produced and consumed indigenous vegetables on the African continent with high nutritional potentials but yet to be fully exploited. This review therefore aims at discussing the current knowledge of the inherent potentials of grain amaranths, its current application in the food industry and proposes a framework for actions and partnerships required to scale up and improve amaranth value chain
