“…In the present study, the DM increase was not enough to alter the other physicochemical characteristics of the re-ensiled silage. Vieira et al (2013) highlighted that corn silages of high-nutritional value have between 7 and 9% CP, 48 and 58% NDF, and 23 and 30% ADF. In the present work, all silage treatments were within these parameters, which evidences the excellent fermentative quality and high-nutritional value of corn silage produced.…”

The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein contents. Conversely, there was a reduction in the nonfiber carbohydrates concentration and in in vitro dry matter digestibility for the re-ensiled material. All changes were explained by the higher-effluent production and DM loss of re-ensiled material that was subjected to two compactions. Microbiology was not altered by the treatments. The use of inoculant altered ash content, but it did not influence other parameters. In contrast, re-ensiling after 36 hours of aerobic exposure caused a reduction in the nutritive value of corn silage and accentuated the DM losses.

“…The DM content of a forage crop is considered as the main factor that determines silage quality according to Vieira et al (2013a). The low DM content of sunflower and millet was related to the studied variety, which exhibited high moisture even at the cut-off point in a certain portion of the plant, such as the stem, probably due to physiological maturity, that is, in the reproductive stage when the back of the heads of sunflower plants turn yellow.…”

Sesamum indicum L. has the potential to be cultivated as a forage plant in hot and dry climate regions, and it can be used to increase the food security of a herd. The objective of this study was to evaluate growth, production, and chemical composition of S. indicum compared with conventional forages used for silage production. The experiment used a randomized complete block design with split-plots related to time and four replicates per treatment. The plots consisted of four treatments (Zea mays L., Helianthus annuus L., Pennisetum glaucum [L.] R. Br., and S. indicum), and the subplots were two evaluation periods (2014 and 2016 harvests). Dry forage biomass production differed among the species in the 2014 harvest with values of 25 530, 12 190, 9408, and 9250 kg ha-1 for Z. mays, S. indicum, H. annuus, and P. glaucum, respectively. Maize had a greater variation in forage production between the 2 yr, followed by S. indicum. There were higher dry matter (DM) contents (P < 0.0001) for Z. mays and S. indicum (404.5 and 251.7 g kg-1 , respectively). Regarding crude protein, H. annuus and S. indicum had levels of 167.2 and 117.7 g kg-1 , respectively. According to the results, it can be inferred that sesame, like millet, provides greater feeding security for ruminant herds in regions with irregular rainfall.

“…Additionally, adequate levels of nitrogen fertilization improve plant performance and increase dry matter production. However, few studies have evaluated the effect of nitrogen fertilization on the morphological characteristics of maize used for silage (MELLO et al, 2005;VIEIRA et al, 2013), and no study has estimated the chemical composition of maize silage based on the morphological characteristics of maize in the field.…”

The aim of this study was to estimate the chemical composition of maize silage based on the morphological characteristics of maize plants and to evaluate the effect of nitrogen fertilization and the inclusion of a microbial inoculant during the ensiling process on the production of maize silage and its morphological, qualitative and fermentative characteristics. The experimental treatments consisted of four levels of nitrogen fertilization with urea (0, 100, 200 and 300 kg ha -1 ) and the inclusion or exclusion of the microbial inoculants during the ensiling process. A completely randomized design was used in a 4 × 2 factorial arrangement of treatments. The maize silage chemical composition was estimated by evaluating the plant height (PH) and ear characteristics (NRE= number of rows per ear; NKE= number of kernels per ear; ELS= ear length with straw; EL= ear length without straw) using the following equations:CP= -12.44 + 5.871 × PH + 0.01814 × NRE² (R²= 0.89; P < 0.0001); NDF= 587.93-0.78×NKE-11.67×ELS-0.47×EL+0.0000007×NKE³+0.006× EL³ (R²=0.92; P = 0.003); ADF= 41.48 -0.046 × NRE 2 (R 2 = 0.42; P = 0.02);TDN= 57.81 -0.0319 × NRE 2 (R 2 = 0.42; P = 0.02);EDDM= 56.58 + 0.035 × NRE 2 (R 2 = 0.42; P = 0.02) andNEL= 1.31 + 0.000757 × NRE 2 (R 2 = 0.41; P = 0.02).In conclusion, nitrogen fertilization increases the silage energy and protein content; while the inclusion of microbial inoculants during the ensiling process does not alter the chemical and fermentative characteristics of the maize silage.Keywords: Plant height.

ResumoO objetivo do presente estudo foi estimar a composição bromatológica da silagem por meio de características morfoló-gicas das plantas de milho, e avaliar o efeito de níveis de adubação nitrogenada e da inclusão de inoculante microbiano na ensilagem sobre as características produtivas, morfológicas, bromatológicas e fermentativas de silagem de milho. Os tratamentos consistiram em quatro níveis de adubações com ureia: 0; 100; 200 e 300 Kg ha -1 , e da inclusão ou não de inoculante microbiano. Foi utilizado um delineamento inteiramente casualizado, com arranjo fatorial de tratamentos 4 × 2. A composição bromatológica da silagem foi estimada pela altura das plantas (AP) de milho e pelas características da espiga (NLE = número de linhas de grãos por espiga; NGE = Número de grãos por espiga; CCP = comprimento da espiga com palha; CSP = comprimento da espiga sem palha) por meio das seguintes equações: PB = -12,44 + 5,871 × AP + 0,01814 × NLE² (R² = 0,89; P < 0,0001); FDN = 587,93 -0,78 × NGE -11,67 × CCP -0,47 × CSP + 0,0000007 × NGE³ + 0,006 × CCP³ (R² = 0,92; P = 0,003); FDA = 41,48 -0,046 × NLE 2 (R 2 = 0,42; P = 0,02); NDT = 57,81 -0,0319 × NLE 2 (R 2 = 0,42; P = 0,02); DMSE = 56,58 + 0,035 × NLE 2 (R 2 = 0,42; P = 0,02) e ELL = 1,31 + 0,000757 × NLE 2 (R 2 = 0,41; P = 0,02). Pode-se concluir que a adubação nitrogenada aumenta o teor de energia e de proteína da silagem; enquanto a inclusão de inoculante microbiano não altera a...
