Expression of the HAHB4 sunflower transcription factor confers drought tolerance to wheat event IND-ØØ412-7 (HB4® wheat). After confirming the compositional equivalence of event IND-ØØ412-7 with conventional wheat, its nutritional similarity to its non-genetically modified (GM) counterpart was analyzed by performing a 42-day broiler feeding study. Isoenergetic diets containing 40% flour from wheat event IND-ØØ412-7, its non-GM counterpart Cadenza, and a commercial variety were included in the study. Broilers' performance was analyzed by measuring feed intake, weight gain, feed conversion, and time to reach 2.8 kgs. The yield was evaluated by carcass weight, breast meat, and abdominal fat. No differences were found between wheat event IND-ØØ412-7 and the non-GM counterpart. A few significant differences were found with the commercial variety which were associated with the genetic background, different from the other two materials. These results support the nutritional equivalence of event IND-ØØ412-7 with conventional wheat.
表达向日葵转录因子 HAHB4 可赋予小麦事件 IND-ØØ412-7(HB4®小麦)耐旱性。在确认事件 IND-ØØ412-7 与常规小麦的成分等效性后,通过进行为期 42 天的肉鸡饲养研究来分析其与非转基因(GM)对应物的营养相似性。该研究包含了含 40%面粉的小麦事件 IND-ØØ412-7、其非 GM 对应物 Cadenza 和一种商业品种的等能量饮食。通过测量饲料摄入量、体重增加、饲料转化率和达到 2.8 公斤的时间来分析肉鸡的表现。通过胴体重量、鸡胸肉和腹部脂肪来评估产量。小麦事件 IND-ØØ412-7 与非 GM 对应物之间没有发现差异。与商业品种存在一些显著差异,这些差异与遗传背景有关,与其他两种材料不同。这些结果支持事件 IND-ØØ412-7 与常规小麦的营养等效性。
