Análise do efeito da colheita da planta de milho em diferentes estádios reprodutivos e do processamento dos grãos sobre a qualidade da silagem

Abstract: ResumoO experimento foi conduzido no Núcleo de Produção Animal (NUPRAN) da Universidade Estadual do Centro Oeste (UNICENTRO), com o objetivo de avaliar o efeito da colheita da planta de milho em diferentes estádios reprodutivos e com diferentes processamentos de grãos sobre a digestibilidade da matéria seca, digestibilidade da fibra em detergente neutro e desempenho animal. O delineamento experimental foi inteiramente casualizado, composto por 4 tratamentos com 4 repetições, onde cada repetição constou de uma … Show more

“…The harvest was performed when the plants reached the ideal physiological stage (fifth stage of the reproductive phase) for silage yield with maximum nutritional efficiency. The whole plants of the useful plot were harvested and the characteristics were measured for Plant Height (PH), Insertion Height of the first ear (IH), Stem Diameter (SD), Ear Diameter (ED), Stem Leaf Weight (SLW), Ear Weight (EW) and Total Plant Weight (TPW) [17].…”

“…In the agrarians sciences, the path analysis is used to measure the correlation of parameters for different cultures, such as canola [12], sunflower [13], jabuticaba fruit [14], soy [15], sorghum [16]. When it comes to silage, it can be highlighted in the maize crop [4,17,18], and other crops, such as sorghum, elephant grass, and soybeans [19,20,21,16].…”

“…Desse modo, é possível inferir que o crescimento de sistemas de confinamentos, somam fatores que contribuem com maior importância na utilização de grãos na elaboração de dietas na bovinocultura de corte. Dessa forma, para potencializarmos a eficiência produtiva em bovinos, a correta associação de fontes concentradas de energia e/ou proteína ao volumoso da ração de bovinos, poderá maximizar o desempenho dos animais, como efeito da complementariedade das taxas de degradação de nutrientes (13).…”

“…As the physiological maturity of the plant progresses, there is also an increase in dry matter yield and a reduction in in vitro dry matter digestibility, thus limiting the use of the fiber portion in the rumen dynamics, in contrast there is greater starch deposition in the grains resulting in a silage with higher energy content. In this case, harvesting requires machinery adaptations to improve grain processing by exposing the endosperm and making more substrate available to the fermenting microorganisms (Marafon et al, 2015). For Neumann, Nörnberg, Leão, Horst and Figueira (2017), the vegetative portion is of great importance in the final quality of the silage, which is mostly constituted by the NDF, and with the advancement of the vegetative stage, there is an increase in the deposition of lignified structures in the NDF, thus promoting a reduction in plant digestibility.…”
