Using Cornell system and NRC dairy model to predict nutrient supply from new super-genotype of oat grain in comparison with two normal varieties of oat
The objectives of this study were to use Cornell system (CNCPS) and NRC-2001 dairy model to predict nutrient supply from super-genotype in comparison with two normal varieties of oat grains. Six oat samples comprised of 3 cultivars (Super-genotype: CDC SO-I and Normal: CDC Dancer, Derby) grown over two years (2005 and 2006) were obtained from the Crop Development Centre at the University of Saskatchewan. Protein and carbohydrate fractions were determined using the CNCPS system. Total digestible nutrient (TDN) and energy values (TDN1x, DE3x, ME3x, NEL3x, DE4x, ME4x, NEL4x of dairy, ME, NEm and NEg of beef) at maintenance and production levels for both dairy and beef cattle were determined using NRC-2001 and NRC-1996 chemical approaches. The detailed results are reported. The information obtained from this study will be useful for oat breeders, feed and livestock industries.
