“…Maize flour prepared from DKC-9089 showed significantly higher peak viscosity, breakdown, setback and final viscosity than those of the MW5021 (Table 2), and this is may be due to relatively and significantly lower crude protein and ash contents, which indicate higher starch content (Table 1). Indeed, it is reported that starch content is prime factor determining viscosity of maize flour (Zilic et al, 2011). Further, Almeida-Dominguez et al (1997 reported that maize flour prepared from softer grain shows higher viscosity than that of harder one, due to loosely packed starch with reduced protein-to-starch bounds in softer maize grain, and such loosely packed starch hydrates and swells more rapidly in the presence of heat and water.…”

The objectives of this study were to evaluate the potential of an orange Malawian local maize variety MW5021 by comparing with a hybrid variety DKC-9089 for nutritional quality and processing properties such as proximate and mineral composition as well as pasting and thermal properties of the flour, and resistance against Prostephanus truncatus infestation during storage of the grain. Maize plants sampled for the experiments were cultivated under three different fertilizer applications, namely 0, 92 and 184 kg-N/ha, considering the chemical fertilizer input among Malawian smallholder farmers. Even without fertilizer input, significantly higher contents of crude protein, Mg, P, Ca, Fe and Zn were observed in MW5021, as compared with DKC-9089. Among pasting properties, setback of the flour slurry from MW5021 was significantly lower than DKC-9089 for all fertilizer treatments. Two-way ANOVA indicated that MW5021 had significantly lower number of grains damaged by P. truncatus than DKC-9089, throughout 12 weeks of storage experiment at 28±2°C. Thus, this study revealed that the Malawian orange local variety MW5021 retained by the smallholder farmers has considerably higher nutritional quality and P. truncatus resistance as well as lower retrogradation hardening after cooking the flour, than the hybrid maize DKC-9089.

Os valores obtidos são corroborados pelos obtidos por Zilic et al (2011), quando avaliaram a composição fibrosa dos grãos de diferentes genótipos de milho, e encontraram variação de 11,0 a 14,7% para teor de FDN.…”

“…É evidente que o teor de fibras na silagem é de grande importância, entretanto para estas condições alguns híbridos de endosperma duro manifestaram baixos teores de fibras, mas não se igualaram em digestibilidade a híbridos dentados também com baixos teores de fibras, corroborando com outros resultados de pesquisas (Ribas et al, 2007;Mendes et al, 2008;Zilic et al, 2011) quando avaliaram híbridos de diferentes texturas.…”

“…Esse fato merece grande atenção no momento da escolha de híbridos para ensilagem, uma vez que os grãos representam de 30 a 45% da massa ensilada Pereira et al, 2012). Os grãos considerados dentados possuem maior proporção de endosperma farináceo, quando comparado a híbridos de endosperma duro (Ribas et al, 2007;Zilic et al, 2011;Piovesan et al, 2011). A presença de uma matriz proteica compacta na porção vítrea do grão dificulta o ataque enzimático, e pode reduzir a digestibilidade ruminal desta porção (Correa et al, 2002;Majee et al, 2008).…”

RESUMOForam avaliados doze híbridos comerciais de milho com grãos duros e dentados em dois locais no Centro Sul do Paraná, com o objetivo de estudar o efeito da vitreosidade dos grãos no comportamento agronômico, valor nutricional e na digestibilidade da massa seca dos grãos e da forragem no ponto de ensilagem. O delineamento experimental foi de blocos ao acaso, e a colheita para análise da qualidade da forragem e dos grãos, foi realizada no estádio de ¾ da linha do leite no grão, correspondente ao ponto de ensilagem. Foram avaliadas características produtivas, vitreosidade, digestibilidade dos grãos e da forragem, bem como características bromatológicas dos híbridos avaliados. Houve efeito significativo para locais, híbridos, e para interação híbridos x locais para características de importância para forragem. Por meio da análise da vitreosidade constatou-se genótipos de milho com textura dos grãos, variando de 50,1 a 75,2% demonstrando variabilidade disponível para o caráter em híbridos comerciais. Os híbridos AS 1572PRO e AG 8041PRO de grãos dentados semi dentados, destacaram-se e podem ser recomendados como sendo de elevada produtividade de massa seca digestível.Palavras-chave: grãos dentados, grãos duros, ponto de ensilagem, vitreosidade, Zea mays Bromatological characteristics of the grain and forage of corn hybrids with different grains textures ABSTRACTWere evaluated twelve commercial corn hybrids with hard and dent grains in two locals in South Central of Paraná State, South Region, Brazil, with the objective of study the effect of the vitreousness of the grains in agronomic behavior, nutritional value and digestibility dry mass of grains and forage, at the silage maturity. The experimental design was randomize blocks, and the harvest for forage and gains quality analysis was performed at the ¾ of the milk line stage in grain, corresponding at silage maturity. Were evaluated yield characteristics, vitreousness, digestibility of grains and forage, as well as bromatological characteristics of the evaluated hybrids. There was significant effect to locals, hybrids and to interaction hybrids x locals, in important forage quality characteristic. The vitreousness analyses possibly to verify corn genotypes with grains textures ranging from 50.1 to 75.2%, showing variability available for the character in commercial hybrids. The hybrids AS 1572PRO and AG 8041PRO, with dent and semi dent grains, stood out and can be recommended as high productivity of digestible dry matter.

Modulation of cecal microbiota in laying hens via intake of genetically modified corn with the maroACC or mCry1Ac genes

BACKGROUND: The present study investigated the chronic effect on the composition and proportions of the cecal microbiota of laying hens for 12 weeks after consuming two genetically modified (GM) corns containing the maroACC gene from the Agrobacterium tumefaciens strain (CC) and the mCry1Ac gene from the Bacillus thuringiensis strain (BT) in comparison with the isogenic corn (CT). RESULTS: In total, 72 hens were randomly assigned to the CT corn-based diet, CC corn-based diet and BT corn-based diet. The absolute weights of abdominal fat, breast, thigh meat and organ weight were not affected by the dietary treatment. Highthroughput 16S rRNA gene sequencing revealed a few differences in the composition of cecal microbiota among the treatments. The only difference with respect to bacterial family was that the cecal abundance of Porphyromonadaceae (3.46 versus 2.11%; P = 0.073) tended to be higher for birds consuming the CC diet than those birds consuming the CT diet. Birds fed the BT diet tended to have a higher abundance of Barnesiella (0.62 versus 0.13%; P = 0.057) and a lower abundance of unclassified Ruminococcaceae (0.64 versus 1.19%; P = 0.097) than those fed the CT diet. Considering beneficial intestinal Barnesiella, this decreases and ultimately clears the colonization of vancomycin-resistant Enterococcus. The unclassified Ruminococcaceae was a low-frequency and low-abundance bacterial taxa and was not associated with intestinal pathology. CONCLUSION: These results indicate a similar modulation of cecal microbiota in laying hens by long-term feeding among transgenic CC corn, BT corn and non-transgenic corn and provide data for biosafety evaluation of the transgenic corn.
