Qualitative parameters of pearl millet silage ammoniated with urea, at different compaction densities

Abstract: -The objective of this work was to evaluate the effects of urea ammoniation of pearl millet silage, at different compaction densities, on chemical composition, losses in the ensilage process, fermentation profile, microbial population count, and aerobic stability. The experimental design was completely randomized, in a 2×4 factorial arrangement, with two compaction densities (600 and 800 kg m -³) and four urea levels (0, 2, 4, and 6% on a dry matter basis), with five replicates. For the aerobic stability assay… Show more

“…According to Freitas et al (2017), urea addition to the pearl millet ensiling process linearly increased the amounts of ammoniacal nitrogen in silages, as follows: 1.97 (N-NH 3 /N in DM) for the silage with 0% urea and 22.67 (N-NH 3 /N in DM) for the silage with 6% urea. In our study, we did not observe an increase in microbial protein synthesis in the animals (Table 6).…”

“…A compactação do material ensilado depende, basicamente, do teor de matéria seca e tamanho de partícula da forragem. Forragens com elevado teor de MS apresentam maior resistência à compactação, dificultando-se atingir a densidade adequada e possibilitando maior volume de ar entre as partículas no silo (FREITAS et al, 2017).…”

“…Partículas muito grandes permitem maior espaçamento entre as frações de forragem, enquanto, partículas muito pequenas podem implicar em maior produção de efluentes. Com isso, indica-se que a forragem seja processada em tamanho de partícula de aproximadamente dois centímetros (FREITAS et al, 2017).…”

“…The ensiling process presents problems related to intrinsic factors of the plant. Low dry matter content, for example promotes the proliferation of undesirable microorganisms that interfere directly in the fermentation and nutritional aspects of the ensiled mass, leading to nutrient losses [6]. Dehydration is a technique used to mitigate losses in the ensiling process for biomasses with high moisture content.…”
