Características agronômicas, bromatológicas e econômicas de alturas de corte para ensilagem da cultura do milho

The aim was to evaluate agronomic, bromatologic and economical characteristics harvest heights for ensiling of corn. The trial was conducted in randomized block design and treatments corresponded to harvest heights of 20; 50; 80 and 110 cm from the soil surface. The agronomic evaluations were conducted 114 days after planting. The percentage of dry matter (DM) and productivity of stem, grain and participation of potassium remaining in the stem increased linearly with increasing cutting height (p<0.05). Therefore, the mass used at ensiling decreased proportionally with increasing cutting height (p<0.05). The silage quality was improved because of the increase in the cutting height. We observed higher crude protein (CP) content and energetic value in the silage harvested at 110 cm from the soil surface, while there was lower fiber content. However, silages produced with plants harvested at 110 cm from the soil surface showed the highest production cost (4.47 times greater than cycling through K in the remainder of the stem). The agronomic and bromatologic characteristics of corn silage improves with increasing cutting height, but the increase cutting height unfeasible economically the practice silage when the generation of final products is not computed. Thus, it is recommended that the cutting height of the corn plant is at most 50 cm.

Degradabilidade e digestibilidade de híbridos de milho em função do estádio de colheita, tamanho de partícula e processamento por meio do esmagamento na ensilagem

During the process of silage corn, should take into consideration some aspects that will result in better utilization. The aim of this study was to evaluate the degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and starch digestibility and in vitro dry matter (DM) of silage corn hybrids due two textures, three stages of harvest, three particle sizes and processing by crushing. After harvesting and chipping, part of the material was crushed and then ensiled and sealed for 45 days. After opening the silos, analyzed the degradability in the incubation time of 20 hours using the technique in situ macro bag. The experimental design was a randomized split plot. The DM degradability was influenced only by the effect of stages of sampling used. The degradability of CP showed interaction between processing and particle size (Tp), noting that increased degradation due to processing. For NDF degradation significant interaction of factors, hybrid and processing, similar to the degradation of starch. The IVDMD was influenced by the effects of hybrid, stadium, Tp and processing. It can be concluded that benefits were higher with the use of processing associated with more advanced stages of harvest, in larger particle sizes.
