In order to evaluate the variability in concentration of secondary metabolites among grains from different sorghum hybrids (Sorghum bicolor (L) Moench) and provide some information for rational use in animal feeds, grain samples were collected from 12 hybrids (Criollo 1, Criollo 27, Chaguaramas III, Chaguaramas VII, Cristiani Burkard H-8046-2, Guanipa 95, Himeca 101, Himeca 400, Pioneer 81-G67, Pioneer 83-G88, Pioneer 86-P42 y Tecsem 120) sowed on 2008 in the Turén municipality, Portuguesa State-Venezuela. Using standardized analytical methods, hybrids showed polyphenolics compounds contents (0.92 +/- 0.37% TaE), total (0.61 +/- 0.29% TaE) and condensed tannins (0.95 +/- 0.65% LeuE), phytic phosphorus (0.17 +/- 0.03%) and intrinsic phytase activity (12.3 +/- 6.74 U/kg) in the ranges described in the literature, with an important variation among hybrids that must be considered for their inclusion levels in the formulation of balanced feeds, as well as plant breeding programs.
为了评估不同高粱杂交种（双色高粱（L）Moench）籽粒中次生代谢物浓度的变异性，并为其在动物饲料中的合理利用提供一些信息，于2008年在委内瑞拉葡萄牙州图伦市播种的12个杂交种（克里奥洛1号、克里奥洛27号、查瓜拉马斯三号、查瓜拉马斯七号、克里斯蒂亚尼·布尔卡德H - 8046 - 2、瓜尼帕95号、希梅卡101号、希梅卡400号、先锋81 - G67、先锋83 - G88、先锋86 - P42和特克塞姆120）中采集了籽粒样本。采用标准化分析方法，杂交种的多酚类化合物含量（0.92±0.37%没食子酸当量）、总单宁（0.61±0.29%没食子酸当量）和缩合单宁（0.95±0.65%亮氨酸当量）、植酸磷（0.17±0.03%）和内在植酸酶活性（12.3±6.74 U/kg）在文献所述范围内，杂交种之间存在重要差异，在配制平衡饲料以及植物育种计划时，必须考虑这些差异以确定其添加水平。
