“…For Kung Jr. and Shaver (2001), the pH of legume silages with 30% DM and perennial temperate grass silage ranges from 4.3 to 4.7. Other studies (Leonel et al, 2008;Souza et al, 2014;Silva et al, 2014) have shown similar values to that observed in the present work for this characteristic.…”

“…The lower fiber contents in legumes in relation to tropical grasses are explained mainly by the physiological differences between them, being the marandu grass a C4 specie and the leguminous C3. Differences in fiber content between grass and legume silages were also observed by Leonel et al (2008) and Silva et al (2015), this result is an indicative of higher digestibility and, consequently, better nutritive value of the silages with legume.…”

The chemical composition, fermentation profile, microbial population and dry matter recovery were evaluated in marandu grass silages containing different levels of Stylo legume cv. Campo Grande treated or not with microbial inoculant. A 4 × 2 factorial arrangement (four levels of Stylo legume, with and without microbial inoculant) was used in a completely randomized design with four replications. The levels of Stylo legume used were 0, 10, 20 and 30% of the weight in the natural matter. The marandu grass was harvested at 70 days of regrowth and the Stylo legume at the pre-flowering stage. It was observed the effect of interaction between levels of Stylo legume and microbial inoculant on dry matter content, effluent losses, dry matter recovery and yeast and molds populations. The dry matter content of the silages with and without inoculant increased (P < 0.05) linearly with the addition of Stylo legume. A linear decreasing effect was observed for neutral detergent fiber contents and a linear crescent effect for the crude protein contents of the silages with addition of Stylo legume. The pH values had a quadratic effect with addition of Stylo legume, with a maximum value of 4.16 in the inclusion of 12.25% of Stylo legume. The LAB population increased linearly with an increase in the levels of Stylo legume. The dry matter recovery increased linearly with the addition of Stylo legume, in the silages without inoculant. It is concluded that the consortium of marandu grass with Stylo legume improves the chemical composition, fermentation profile, and decrease the dry matter losses of the silages, regardless of the use of microbial inoculant.

“…Silages of legume alone have poor quality due to high buffering power and low soluble carbohydrate content (Lima, Lourenço, Díaz, Castro, & Fievez, 2010). Nevertheless, the use of legumes mixed with grasses improves the quality of the ensiled mass and increases the protein content when compared to the silage of corn or sorghum alone (Leonel et al, 2008;Lima-Orozco, Castro-Alegría, & Fievez, 2013).…”

This study evaluated the effect of increasing levels of leucaena forage in sorghum: forage. In addition to pure sorghum, it was evaluated different levels of inclusion of leucaena (15, 30 and 50%) at the time of ensiling. Forage was ensiled in PVC tubes (100 mm diameter, 500 mm length) under the density of 500 – 600 kg m-3, a total of 20 silos were prepared, which were opened 35 days after ensiling. There was no effect (p > 0.05) of leucaena inclusion levels for pH, water activity (Aw) and total ammonia nitrogen (total NH3-N). There was an increasing linear effect (p < 0.05) for the content of dry matter (DM), crude protein (CP) and lignin that increased from 33.47 to 34.75%, 7.82 to 16.05% and from 7.29 to 9.93%, at the levels from 0 to 50% inclusion of leucaena, respectively. There was a decreasing linear effect (p < 0.05) for neutral detergent fiber corrected for ash and protein (NDFcp) and hemicellulose, which reduced from 56.65 to 48.37% and from 24.07 to 17.67% at the levels of 0 and 50% inclusion, respectively. For the ash content, there was a quadratic effect (p < 0.05), with a maximum at 8.3% with 8.9% inclusion of leucaena. The inclusion of up to 50% leucaena into sorghum silage is recommended, because, in addition to maintaining the fermentation quality, it also improved nutritional quality of sorghum silage.

“…Entretanto, o teor de proteína não seria a única causa de tamponamento, uma vez que minerais como o cálcio podem também contribuir com íons nos sistemas tampões. Leonel et al (19) , ao avaliarem as características qualitativas de vários tipos de silagens, concluíram que os elevados teores de proteína e MM dificultam a conservação da silagem, em decorrência do aumento da concentração de amônia e elevada capacidade tamponante. Além desses fatores, as características microbiológicas do soro de leite podem influenciar diretamente nas produções de gases e perdas na MS da silagem.…”

“…Segundo Ramos et al (30) , os lipídios provenientes da silagem de resíduo de tilápia podem reduzir a excessiva solubilização da proteína no material, contudo, a presença de óleo juntamente aos altos níveis de ácidos graxos poli-insaturados, que estão sujeitos à oxidação, pode tornar a silagem não palatável e imprópria ao consumo do animal. Além disso, altas concentrações de PB prejudicam a conservação da silagem devido à alta concentração de amônia no material e alteração da capacidade de tamponamento (19) .…”

1Universidade José do Rosário Vellano -UNIFENAS, Alfenas, MG, Brasil. *Autor para correspondência -adauton.rezende@unifenas.br ResumoObjetivou-se avaliar as características bromatológicas, microbiológicas e perdas fermentativas da silagem de grão de milho reidratado com água ou soro de leite associado a diferentes níveis de inclusão do resíduo de tilápia. Utilizou-se um delineamento inteiramente casualizado em esquema fatorial 5x2 (cinco níveis de inclusão do resíduo de tilápia: 0; 12,5; 25; 37,5 e 50% em substituição ao milho reidratado e duas fontes de reidratação do grão de milho: água ou soro de leite) para produção de silagem). A produção de gases da silagem com até 25% de inclusão do resíduo de tilápia foi 62,7% maior para o milho reidrato com soro de leite (P <0,01). A quantidade de bactérias ácido láticas foi menor em todos os níveis de inclusão de resíduo de tilápia quando a fonte de reidratação foi a água (P<0,01). Os teores de matéria mineral, matéria orgânica, proteína bruta, extrato etéreo, cálcio e fósforo foram maiores nas silagens reidratadas com soro de leite com o aumento do nível de inclusão de resíduo de tilápia (P<0,01). A silagem de resíduo de tilápia com milho reidratado é uma alternativa que pode ser utilizada na dieta de aves e suínos, entretanto, o seu uso está condicionado às avaliações do melhor nível de inclusão dentro de uma categoria animal.Palavras-chave: Alimento alternativo.

AbstractThe objective of this study was to evaluate the microbiological, chemical characteristcs and fermentative losses of corn silage rehydrated with water or whey associated to different levels of tilapia residue inclusion. A completely randomized design was used in a 5x2 factorial arrangement (five inclusion levels of tilapia residue: 0; 12.5; 25; 37.5 and 50% in substitution of dehydrated corn; and two sources of rehydration of corn: water or whey) for silage production. The production of gases of the silage with up to 25% inclusion of the tilapia residue was 62.7% greater for the corn rehydrate with whey (P <0.01). The amount of lactic acid bacteria was lesser for all levels of inclusion of tilapia residue when the source of rehydration was water (P <0.01). The levels of mineral matter, organic matter, crude protein, ethereal extract, calcium and phosphorus were greater in silages rehydrated with whey with the increase of the inclusion level of tilapia residue (P <0.01). Tilapia residue silage with rehydrated corn is an alternative that can be used in the poultry and swine diet, however, its use
