“…This increase in pH could be explained by higher BC of legumes as a result of higher protein and organic acid content than with grasses. The differences between the highest pH values and the lowest ones among intercropping ratios was small (0.08), and all of the intercropping ratios gave a pH range ideal for silage (Cherney and Cherney, 2003). Lower pH of silage from intercropping ratios compared with soybean monoculture in this study has been associated with greater WSC content of the grass.…”

Shortage of irrigation water in arid and semi-arid regions has forced forage producers to look for drought-tolerant species for silage production. To evaluate silage yield and nutritive value of pearl millet (Pennisetum glaucum L.)-soybean [Glycine max (L.) Merr.] intercrops as influenced by intercropping ratios and N rates, a 2-yr field experiment was conducted using split-plot lay out on a randomized complete block (RCB) design. Main plots consisted of 0, 37, and 74 kg N ha -1 (N 0 , N 37 , and N 74 , respectively) and intercropping ratios of millet and soybean (50%M:50%S; 60%M:40%S; and 40%M:60%S) along with monocultures were assigned to subplots. Increasing N resulted in 9.9 and 17.6% silage yield increase at N 37 and N 74 levels compared with N 0 . Nitrogen also increased organic acids and ammonia nitrogen (NH 3 -N) content. Silage pH was lower (4.23) where no fertilizer was applied compared with the fertilized plants (4.33). The highest crude protein (CP) content (170 g kg -1 dry matter [DM]) and dry mass (248 g DM kg -1 fresh weight) was at the N 74. Silage produced by the millet-soybean mixtures was well fermented indicated by low pH and high lactic acid. Also, intercropping ratios had less acid detergent fiber (ADF) and neutral detergent fiber (NDF) than monocultures. Although all of the intercropping ratios had characteristics of well-fermented silage, a mixture of 60% millet and 40% soybean could be superior because of higher silage yield and CP. ¶ Means of intercropping ratios in the same column followed by different letters differ significantly at P = 0.05 by Duncan's New Multiple Range Test. # M and S represent millet and soybean, respectively.

“…IAPAR 61 showed only 74.1 g kg -1 crude protein in its composition, but this value is similar to that described by David et al (2010), 79.0 g kg -1 . However, when the silage fermentation process is taken into account, this low content of crude protein reduces the buffering capacity of the ensiled material, providing a quick pH drop and stabilizing the ensiled masses faster (Cherney & Cherney, 2003).…”

This study aimed to assess the chemical composition of the forage and pre-dried silage from twelve winter cereals harvested at pre-flowering. We used black oat (Avena strigosa) cv. EMB 139 and cv. IAPAR 61; white oat (Avena sativa) cv. IPR and 126 hp. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Triticum aestivum) cv. BRS Umbu and cv. BRS Tarumã; rye (Secale cereale) cv. Temprano and cv. BRS Serrano; and triticale (X. Triticosecale) cv. IPR and 111 hp. BRS Saturno. Plants were harvested at pre-flowering, when they were pre-dried and ensiled. The analysis of variance evidenced nutritional differences between species and cultivars. Triticale cv. IPR 111 showed notorious chemical characteristics in relation to the other treatments, highest protein content (113.7 g kg-1) and lower content of NDF and ADF (657.9 and 380.9 g kg-1, respectively). Among the pre-dried silages, barley cv. BRS Cauê had the highest level of NDT (614.7 g kg-1). Triticale cv. IPR 111 was shown as a high-quality nutritional food as forage and kept these characteristics after conservation. On the other hand, the pre-dried silage of barley cv. BRS Cauê showed the highest potential for nutrient degradability.

Considering the hypothesis that density and dry matter (DM) concentration may be used as indicators of silage nutritional quality, the aim of the present study was to determine density and maturation stage (i.e. DM concentration) of corn silages under farm conditions in Brazil, establishing relationships between density and physical and chemical characteristics. In a completely randomized design, 20 bunkers of corn silage, each from a different farm, were used for data collection. Using a coring machine, 5 samples of silage were extracted from an exposed face of each silo and samples were analyzed for density of compaction, plus concentrations of DM, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN), total carbohydrate (TC), non-fiber carbohydrate (NFC) and starch (STA), as well as electrical conductivity. There was significant variation in many of the parameters measured with the greatest variation in density on a natural matter basis. Negative correlations were observed between percentages of DM, NDF and ADF in the silage and silage density on a natural matter basis (P<0.05). On the other hand, DM% was positively correlated with concentrations of STA, TDN and TC (P<0.05). Density on a DM basis showed positive correlation with STA but was negatively correlated with NDF and ADF (P<0.05) indicating that the more fibrous material is harder to compact. A technology transfer program seems warranted to inform Brazilian farmers of these findings and the importance of harvesting forage at a stage of growth when quality would be better to increase the probability of achieving adequate compaction of the ensiled material and hence better quality of material at feeding out.
