Chemical composition and ruminal nutrient degradability of fresh and ensiled amaranth forage.

Background: Amaranth is a crop with potential as a source of forage for ruminants that has not been well characterized. A study was conducted to determine the impact of ensiling on the nutritional quality and ruminal degradability of forage from two amaranth cultivars adapted to North America (i.e.

Chemical composition, dietary fibre, tannins and minerals of grain amaranth genotypes.

The objective of this study was to determine the chemical composition of 28 white and coloured grain amaranth (Amaranthus spp.) genotypes. Neutral detergent fibre (NDF) concentration was greater while strach concentration was lower for coloured seeds genotypes than white seeds genotypes.

Oxalate in grain amaranth.

Grain amaranth (Amaranthus spp.) is a widely adaptable C4 pseudo-cereal crop that has interesting nutritional characteristics including high protein and calcium concentrations and a lack of gluten. To date, no antinutrient has been found at problematic levels in grain amaranth; however, oxalate has not been thoroughly studied.
