Abstract

A grower finisher performance trial with forty-eight pigs was designed to compare the growth performance of pigs fed diets containing either genetically modified (GM) Bt-maize (NX6262) or its parental maize (Prelude) line. During the experiment, the pigs were fed with a grower and a finisher diet both containing 70% maize investigated in a previously study which showed that they contained similar ME values and digestibility of crude nutrients. The pigs with an initial live weight of 23.9 +/- 3.0 kg were allotted to single boxes. During a 91 days growing period the pigs of both groups recorded equal performance in daily weight gain (AW) 815 +/- 93 vs. 804 +/- 64 g/d depending on equal amounts of feed intake 1.95 +/- 0.15 vs. 1.94 +/- 0.15 kg/d (parental vs. transgenic). The results confirm equal performance among growing-finishing pigs fed parental or genetically modified maize containing diets. For slaughtering the pigs were divided into 4 groups with a different duration of the finishing period. After slaughtering the carcass characteristic were registered.

转基因玉米(Bt-maize)在猪营养中的研究:肥育性能和屠宰效果。

采用48头猪进行生长育肥猪性能试验，比较饲粮中含有转基因bt玉米(NX6262)及其亲本玉米(Prelude)系的猪的生长性能。在试验期间，猪分别饲喂含有70%玉米的生长和育肥猪饲粮，这两种饲粮的代谢能值和粗营养物质的消化率相似。初始活重为23.9±3.0 kg的猪分配为单箱饲养。在91天的生长期，两组猪的日增重(AW)相同，分别为815 +/- 93和804 +/- 64 g/d，取决于采食量(1.95 +/- 0.15和1.94 +/- 0.15 kg/d)。结果证实，饲粮中含有亲本或转基因玉米的生长肥育猪的生产性能相同。屠宰时按肥育期长短分为4组。屠宰后对胴体特征进行登记。
