“…The results of total and digestible amino acids as well as metabolizable energy indicated remarkable variations among the transgenic technologies. These differences can be attributed not only to the genetic characteristics but also tissue structure of corn grains [ 9 ]. In 2020, a significant difference in the dig.…”

“…In addition to its recognized nutritional value, corn is also known as a natural source of carotenoids and xanthophyll [ 7 ], important pigments for the poultry industry, with them being deposited into the poultry skin and egg yolk. Despite being marketed as a commodity, there is substantial variability in its nutritional characteristics caused by several factors such as seed genetics, endosperm texture, cultivation location, climatic conditions, post-harvest management, and storage [ 8 , 9 ]. The current scenario emphasizes the importance of understanding the nutritional nuances of corn and the main factors involved.…”

Corn is one of the most produced cereals in the world and plays a major role in poultry nutrition. As there is limited scientific information regarding the impact of transgenic technology on the quality and nutrient composition of the grains, this study investigated the effect of three major transgenic corn varieties—VT PRO3®, PowerCore® ULTRA, and Agrisure® Viptera 3—on the field traits, nutrient composition, and mycotoxin contamination of corn grains cultivated in southern Brazil during three consecutive harvests. VT PRO3®, while demonstrating superior crop yield, showed susceptibility to mycotoxins, particularly fumonisins. In contrast, PowerCore® ULTRA, with the lowest yield, consistently exhibited lower levels of fumonisins. VT PRO3® had higher AMEn than the other varieties, while PowerCore® ULTRA had the highest total and digestible amino acid contents over the three years. The study’s comprehensive analysis reveals the distinct impact of transgenic corn technologies on both productivity and nutritional levels. Balancing the crops yield, mycotoxin resistance, and nutritional content of corn is crucial to meet the demands of the poultry feed industry. Such insights are essential for decision-making, ensuring sustainability and efficiency in agricultural production as well as meeting the demands of the poultry industry.

“…The endosperm is the storage tissue of corn and its structure has been related to agronomic traits, nutritive values and grain quality. 2,3 It is basically composed of starch granules, which can be arranged in floury and vitreous forms. The floury endosperm comprises loosely packed round starch granules, whereas the vitreous endosperm presents compact and polygonal starch granules linked to the protein matrix of the endosperm.…”

BACKGROUNDMycotoxin monitoring in cereal grains has great importance in the food and feed industries. This study evaluated mycotoxin contamination in corns with different endosperm textures in 2 years of cultivation. Samples of dent, semi‐dent, flint and semi‐flint corns from field experiments were analyzed by high‐performance liquid chromatography coupled with tandem mass spectrometry (HPLC‐MS/MS).RESULTSOccurrences of fumonisins B1 (FB1) and B2 (FB2) in 2020 were 45.72% (mean 270 μg kg−1) and 35.89% (94.97 μg kg−1), respectively, and 68.98% (446 μg kg−1) and 45.83% (152 μg kg−1) in 2021. Occurrence of aflatoxin B1 was 11.96% (0.16 μg kg−1) in 2020 and 11.11% (0.13 μg kg−1) in 2021. In 2020, deoxynivalenol (DON) and zearalenona (ZEA) presented occurrences of 1.28% and 1.70%, with means of 4.08 and 2.45 μg kg−1, respectively. In 2021, results were 8.33% (31.00 μg kg−1) for DON and 8.79% (4.38 μg kg−1) for ZEA. Citrinin, diacetoxyscirpenol and fusarenon‐X did not occur in 2020 but presented 1.66%, 0.83%, and 2.50% positive rates in 2021, respectively. In 2020, flint corn presented the lowest concentration of FB1 whereas dent corn presented the highest concentration of FB1 and FB2 (P < 0.05). In 2021, dent corn presented the highest means of FB1, FB2 and diacetoxyscirpenol (P < 0.05). Dent and semi‐dent presented the highest concentration of nivalenol (P < 0.05).CONCLUSIONThe endosperm texture influenced mycotoxin contamination in corn grains, especially FB1 and FB2, which had the highest concentration in dent corn in the 2 years of this study. © 2023 Society of Chemical Industry.
