“…Silage effluents are also a source of losses and that occur more often in silages that have high moisture content (Rego et al 2012), and in situations where it is not possible to reach the required DM. Nevertheless, the corn silage presented lower losses by effluents because the plant had already reached an advanced maturation stage and presented at the time of ensiling 404.50 g kg À1 of DM.…”

The objective was to evaluate the fermentation parameters, chemical composition and in situ degradability of sesame silage in comparison to usual silages. The losses, fermentation quality and chemical composition of the forages and silages were evaluated using a completely randomised design with four treatments (sesame, corn, millet and sunflower) and four replicates per treatment, the silages were produced in experimental silos. In-situ degradability was evaluated using a completely randomised design with four treatments and three replicates (animals) per treatment. The results were statistically evaluated by analysis of variance and Tukey's test with a level of 5% of probability. Three rumen fistulated non-castrated Santa Inês rams were used. Sunflower and corn silages presented higher percentages of losses through gases (p ¼ .0256). Millet silage presented higher losses by effluent (p < .0001). The dry matter recovery (p < .0001) ranged from 70.0 to 96.5% for sesame and corn silage, respectively. The dry matter content (p ¼ .0002) in the silages ranged from 280.0 to 429.4 g kg À1. The sesame silage presented loss amounts and fermentation parameters similar to those found in corn and sunflower silage. Sesame silage showed moderate dry matter (DM), content, excellent crude protein (CP) and total digestible nutrients (TDN) contents, and low lignin content. Corn silage presented higher concentration of the soluble fraction of DM (p < .0001). The sesame silage presented a high degradability rate of DM and it was similar to corn and millet which have great nutritional potential for ruminants feeding. Sesame has the potential to produce quality biomass and silage for animal feeding. HIGHLIGHTS The sesame can be an option for silage making. Sesame helps to ensure sustainability by promoting lower seasonal risks in this region through the usage of silage as feed for the animals. Sesame also increases the productivity of livestock throughout the year, through the availability of feed for the herd mainly during the dry season of the year.

“…The changes in fiber fractions probably decreased the digestibility of silages with PCP, as the additive originally contained higher amounts of lignin and NDF compared with the levels found in wet orange peel. Yet, the CP levels of all silages were higher than the 70 to 75 g kg −1 usually found in wet orange peel silages (Rego et al, 2012;Valença et al, 2016). Probably, the increase in protein concentration may be due to soluble carbohydrate consumption during the fermentation process that led to an indirect effect of protein concentration (Bernardes et al, 2005).…”

This study evaluated the effects of pelleted citrus pulp (PCP) added to orange peel on fermentative parameters and aerobic stability of orange peel silages. The treatments were based on different levels of PCP: 0 (control), 10% PCP, 20% PCP, and 30% PCP calculated according to the weight of orange peel (w/w), with five experimental silos per treatment stored for 60 days. Chemical composition, fermentative parameters, microbial population, and dry matter (DM) losses were performed in silages after opening the experimental silos. Furthermore, aerobic stability was evaluated for 12 days. Silages with 10 and 20% PCP presented suitable levels of DM, 226 and 302 g kg −1 , respectively, and probably adequate water activity that benefited the lactic acid fermentation, but it jeopardized their aerobic stabilities. The inclusion of 10% PCP did not reduce the effluent loss compared with the control silages. Yet, 30% PCP silage showed the lowest effluent loss (93%), in contrast to the low lactic acid content (35 g kg −1 ) and short aerobic stability (49 h). Control silages remained stable for a longer period (115 h), but showed greater loss of N as NH 3 , and higher losses of DM through gas (354 g kg −1 ) and effluents (114 g kg −1 ). In short, we highlighted 20% PCP silage because of its high lactic acid bacteria (6.3 cfu g −1 ), high lactic acid:acetic acid ratio (1.41), low nitrogen degradation as NH 3 , and reduced gas (67%) and effluent (80%) productions. With the highest lactic acid (66.42 g kg −1 ), these well-preserved silages showed a more intense aerobic degradation, starting after 42h. The inclusion of PCP to orange peel improves the fermentation process probably due to the decrease of water activity, but decreases the aerobic stability of the silage as well.

“…A composição químico-bromatológica do concentrado, da silagem de sorgo e de bagaço de laranja, bem como das misturas utilizadas nas dietas encontrase na Tabela 1. A composição da silagem de bagaço de laranja apresentou valores condizentes com o encontrado por outros autores (ÍTAVO et al, 2000a;REGO et al, 2012;VILLANUEVA et al 2013), com algumas variações, que de acordo com Ammerman & Henry (1991), podem ser atribuídas aos diferentes processos de extração do suco, procedência e variedade dos frutos. A ingestão de matéria seca (IMS) em kg/dia foi afetada de forma significativa pelos tratamentos, apresentando comportamento quadrático (P<0,01) em função do aumento da quantidade de silagem de bagaço de laranja nas dietas experimentais (Tabela 2).…”

Avaliou-se o desempenho e as características de carcaça de tourinhos mestiços confinados, alimentados com dieta contendo diferentes níveis de silagem de bagaço de laranja (0, 20, 40 ou 60%) substituindo a silagem de sorgo (% da matéria seca). Foram utilizados 36 animais distribuídos em baias individuais, em um delineamento inteiramente casualizado com nove repetições. A ingestão de matéria seca (IMS) apresentou incremento quadrático (P<0,01) em função dos níveis de silagem de bagaço de laranja na dieta. O ganho médio diário (GMD) também teve comportamento quadrático (P<0,01) em função do incremento da silagem de bagaço de laranja, estimando-se que o nível que permite máximo GMD é de 24,50%. Entretanto, ao se comparar as médias de GMD observou-se que a dieta com 20% de silagem de bagaço de laranja não diferiu das dietas com silagem de sorgo exclusiva e 40% de silagem de bagaço. A conversão alimentar não foi afetada pelas dietas (P>0,05), apresentando valor médio de 6,52. As características de carcaça não sofreram alterações (P>0,05) em função dos tratamentos. Foram observados valores médios de 298,37 kg; 13,50; 135,14 cm; 26,35 cm; 72,17 cm²; 5,26 mm; 5,81; 64,54%; 21,05%; 15,09%, para peso de carcaça quente, conformação, comprimento de carcaça, espessura de coxão, área de olho de lombo, espessura de gordura subcutânea, marmoreio e porcentagens de músculo, gordura e osso, respectivamente. A silagem de bagaço de laranja pode substituir a silagem de sorgo em até 40% da matéria seca, mas o nível de 24,5% é o que proporcionou máximo desempenho dos animais.
