“…Dietary energy in grass silage may be considerably low compared with corn or sorghum silages (Carvalho et al, 2016), which may be compensated by offering greater proportions of concentrate to ensure weight gain in animal production systems. However, this may configure considerable increases in the production costs.…”

-The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg −1 of DM silage) and two cutting ages (45 and 60 days) with four replicates per treatment (silos). The parameters of dry matter losses, effluents losses, gas losses, pH, microbial population, and nutritional value of the silage were evaluated. There was no difference in pH among the tested doses of crude glycerin. However, reductions in dry matter and gas losses were observed as a function of crude glycerin doses. Bacterial populations of lactic acid and facultative mesophilic anaerobes also increased as a function of crude glycerin inclusion. Crude glycerin increased ether extract levels and reduced neutral detergent fiber and acid detergent fiber concentrations (dilution effect), improving chemical composition of the silage. Crude glycerin can be used in the ensiling of Piatã grass and the dose of 300 g kg −1 of DM yields the best results.Key Words: biodiesel, byproduct, forage conservation, glycerol, ruminants Revista Brasileira de Zootecnia

“…On the other hand, sorghum's production cost is lower than maize in a single seeding with more than one cut, and the nutritional quality is 10-15% lower than maize (Carvalho et al, 2016). Also, sorghum's high moisture content and thick stem structure make it more suitable for ensiling than hay production (Liang et al, 2018).…”

The current study aimed to determine the nutritional quality and aerobic stability of sorghum, maize, and their mixture silages without any additives. Sorghum and maize were harvested at dough stage from a local farm in Tekirdağ. Fresh plant materials were chopped to a length of 2-3 cm and packed into polythene bags, and vacuumed. A total of 12 vacuum-packed silos (4 replications in each treatment) were prepared with sorghum (S), maize (M), and a mixture of sorghum-maize (SM) forage (w:w, 50:50 according to dry matter) and stored at room temperature for 60 days. The chemical and microbiological composition of silages with the rate of aerobic deterioration upon aerobic exposure were evaluated. Based on the pH and ammonia nitrogen concentration, all silages could be classified as good quality. The water-soluble carbohydrate level of the SM group increased due to mixing S and M forages, leading to improved lactic acid content. The NDF and ADF values of silages varied between 520.52-588.32 and 234.98-309.01 g kg -1 , and the differences between silages were significant (P<0.01). The Hemicellulose/Cellulose ratio of S, M, and SM silages were found 0.94, 1.49, and 1.18, respectively. The lactobacilli and yeast content of silages were significant and varied between 5.18-7.41 and 5.18-7.29 log cfu g -1 , and the highest and lowest values were observed in SM and S silages, respectively (P<0.01). No visible mold was detected in all silages after 5 days of aerobic exposure (P>0.05). The pH, CO2, and yeast numbers were varied in groups between 4. 88-6.74, 55.71-119.33 g kg -1 , and 8.40-9.01 log cfu g -1 . It was concluded that it is possible to improve the nutritional and fermentation characteristics of sorghum and maize silage by ensiling their mixture. However, it is highly recommended that silage additives should be used to guarantee and strengthen the fermentation and aerobic stability of silage mostly made by a mixture of these two energetic forage crops.

“…Os temas de pesquisa que envolvem as culturas de milho e sorgo relacionam-se à identificação de genótipos adequados para a produção de silagem (CARVALHO et al, 2016), modelagem e estimação de produtividade (SILVA et al, 2015), nutrição (KHOSRAVI et al, 2018), altura de corte (REZENDE et al, 2015), época de corte (DE SOUZA et al, 2017), época de semeadura (MENDES et al, 2015), densidade populacional (HADDADI e MOHSENI, 2016), métodos de conservação (MACÊDO et al, 2017), dentre outras. Dessa forma, a utilização de silos experimentais de tamanho comercial torna-se inviável, sendo necessário estudos que indiquem alternativas viáveis que não alterem a conservação dos materiais ensilado e permitam os mais diferentes estudos.…”

Objetivou-se, com o presente estudo, testar diferentes tipos, formas e volumes de silos experimentais na produção de silagem de milho e sorgo, para as principais características bromatológicas, matéria seca e concentração de nutrientes no tecido ensilado. O experimento foi conduzido na área experimental da Universidade Tecnológica Federal do Paraná, no Campus Dois Vizinhos no período entre dezembro de 2008 a junho de 2009. Os silos experimentais testados em ambas as culturas foram: baldes plásticos rígidos, com capacidade para 3 L e 15 L; canos de PVC de diferentes comprimentos e diâmetros, contendo ou não uma base com areia para armazenamento de efluentes; sacolas de plástico flexível com capacidade para 5 kg e 10 kg; e garrafas PET, com capacidade para 2 L. As características avaliadas foram: matéria seca, proteína bruta, fibra em detergente neutro, fibra em detergente ácida, extrato etéreo, matéria mineral, energia líquida de lactação, nutrientes digestíveis totais, teores de nitrogênio, fósforo, potássio, cálcio e magnésio no tecido vegetal. Também foram estimados os valores de ingestão de matéria seca, energia líquida de lactação e nutrientes digestíveis totais. Como resultados, verificou-se que o tipo de microssilo experimental não interfere nas características bromatológicas e teores de nutrientes, apenas o teor de matéria seca foi diferente entre os microssilos, para as culturas do milho e sorgo.
