Dehulled soybean meal prepared from genetically modified, herbicide (glyphosate)-tolerant Roundup Ready soybeans containing the CP4 EPSPS protein and near-isogenic conventional soybeans were assessed in an experiment with growing-finishing pigs. The soybeans were grown in the yr 2000 under similar agronomic conditions except that the Roundup Ready soybeans were sprayed with Roundup herbicide. Both were processed at the same plant. The composition of the two types of soybeans and the processed soybean meal were similar. Corn-soybean meal diets containing conventional or Roundup Ready soybean meal and fortified with minerals and vitamins were fed to 100 cross-bred pigs from 24 to 111 kg BW. Diets contained approximately 0.95% lysine initially and were reduced to 0.80 and 0.65% lysine when pigs reached 55 and 87 kg BW, respectively. There were 10 pens (five pens of barrows and five pens of gilts) per treatment with five pigs per pen. All pigs were scanned at 107 kg mean BW and all barrows were killed at the end of the test for carcass measurements and tissue collection. Rate and efficiency of weight gain, scanned backfat and longissimus area, and calculated carcass lean percentage were not different (P > 0.05) for pigs fed diets containing conventional or Roundup Ready soybean meal. Gilts gained slower, but they were more efficient and leaner (P < 0.05) than barrows. Responses to the type of soybean meal were similar for the two sexes with no evidence of a diet x sex interaction for any of the traits. In most instances, carcass traits of barrows were similar for the two types of soybean meal. Longissimus muscle samples from barrows fed conventional soybean meal tended (P = 0.06) to have less fat than those fed Roundup Ready soybean meal, but water, protein, and ash were similar. Sensory scores of cooked longissimus muscles were not influenced (P > 0.05) by diet. The results indicate that Roundup Ready soybean meal is essentially equivalent in composition and nutritional value to conventional soybean meal for growing-finishing pigs.

Очищенная мука готовилась из генетически модифицированой глифосат-устойчивой сои Roundup Ready, содержащей белок СР4 EPSPS и ближайшей обычной сои, и была оценена в эксперименте со свиньями. Соевые бобы вырастили в 2000 году при аналогичных агрономических условиях за исключением того, что соя Roundup Ready была обработана гербицидом Roundup. Состав двух видов соевых бобов и обработанного соевого питания был идентичен. Диетой из соевой мукой, содержащей обычную и Roundup Ready сою обогащенную минералами и витаминами, кормили 100 свиней первого поколения от 24 до 111 кг массы тела. Изначально диеты содержали примерно 0,95% лизина, содержание которого было снижено до 0,80 и 0,65%, когда свиньи достигли веса 55 и 87 кг. Все свиньи прошли УЗИ при весе в среднем 107 кг и были убиты в конце испытания для измерения туш и тканей. Размер и производительность привеса (и прочие показатели) не отличались (Р> 0,05) для свиней, рацион которых содержал обычную и RR сою. Вывод: результаты показывают, что Roundup Ready соя существенно эквивалентна по своему составу и питательной ценности обычной сое.
