ABSTRACT

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.

摘要

HAHB4 向日葵转录因子的表达赋予小麦事件 IND-ØØ412-7（HB4® 小麦）耐旱性。在确认事件 IND-ØØ412-7 与传统小麦的成分等同性后，通过进行为期 42 天的肉鸡饲养研究，分析了其与其非转基因 (GM) 对应物的营养相似性。该研究包括含有 40% 来自小麦事件 IND-ØØ412-7、其非转基因对应物 Cadenza 和商业品种的面粉的等能饮食。通过测量采食量、增重、饲料转化率和达到 2.8 公斤的时间来分析肉鸡的生产性能。产量通过胴体重量、胸肉和腹部脂肪来评价。在小麦事件 IND-ØØ412-7 和非转基因对应物之间没有发现差异。与其他两种材料不同的是，与遗传背景相关的商业品种存在一些显着差异。这些结果支持事件 IND-ØØ412-7 与传统小麦的营养等价性。
