To expand the use of whole crop rice (WCR), accurate information on the nutritional value of newly developed varieties is required. We cultivated three new WCR varieties (Oryza sativa cv. Suweon 605, Yeongwoo and Mogwoo) developed by the National Institute of Crop Science in the southern Korean Peninsula and evaluated their feed value (crude protein, CP; acid detergent fiber, ADF; neutral detergent fiber, NDF; in vitro dry matter digestibility, IVDMD; total digestible nutrients, TDN; and relative feed value, RFV) and functional materials (β‐carotene and α‐tocopherol). Oryza sativa cv. Suweon 605 showed the earliest heading date and Yeongwoo the highest dry matter (DM) yield; however, there were no significant differences among varieties (p > 0.05) in DM yield. The CP content was highest in Mogwoo, and higher in leaves and grains than in stems. Oryza sativa cv. Suweon 605 had the lowest ADF and NDF contents but the highest TDN and RFV. The grain nutrient value changed drastically in all varieties by 10 days after heading. The grain ratio was highest in Oryza sativa cv. Suweon 605 at 65.6% and lowest in Mogwoo at 12.3%. The leaf β‐carotene content was 7–15 times higher than that in stems and grains, and this increase was higher in Yeongwoo (66.25 mg/kg) than those of all other measured objectives in this experiment (p < 0.05). Similar trends were observed in α‐tocopherol content. Based on these results, Oryza sativa cv. Suweon 605 is recommended in terms of feed value and Yeongwoo is recommended for its high productivity. Because the feed value changed rapidly by 10 days after heading, it is desirable to ensure a later harvest time. The effects of functional materials on livestock performance require further study.

整作物水稻品种的产量和品质与植物成分的关系

为了扩大整粒水稻的使用，需要有关新开发品种的营养价值的准确信息。我们在朝鲜半岛南部的国家作物科学研究所培育了三个新的WCR品种（水稻Oryza sativa cv。Suweon 605，Yeongwoo和Mogwoo），并评估了它们的饲料价值（粗蛋白，CP，酸性洗涤剂纤维，ADF，中性洗涤剂）纤维，NDF；体外干物质消化率，IVDMD；总可消化营养物，TDN；相对饲料价值，RFV）和功能物质（β-胡萝卜素和α-生育酚）。Oryza sativa cv。Suweon 605的抽穗期最早，而Yeongwoo的干物质产量最高。但是，品种之间没有显着差异（p > 0.05）的DM产量。CP含量在Mogwoo中最高，在叶和谷粒中高于茎。Oryza sativa cv。Suweon 605的ADF和NDF含量最低，但TDN和RFV最高。抽穗后10天，所有品种的谷物营养价值发生了巨大变化。水稻的谷粒比最高。Suweon 605为65.6％，在Mogwoo最低，为12.3％。叶片中的β-胡萝卜素含量比茎和谷粒中的含量高7至15倍，并且在本试验中，Yeongwoo（66.25 mg / kg）的该含量高于所有其他测量目标的含量（p  <0.05）。α-生育酚含量也观察到类似趋势。根据这些结果，水稻简历。建议使用Suweon 605的饲料价值，建议使用Yeongwoo的高生产率。由于抽穗后10天饲料价值迅速变化，因此需要确保以后的收获时间。功能材料对牲畜性能的影响需要进一步研究。
