“…According to McDonald (1981), 80% of the resistance to a pH decline in forages with high buffer capacity are due to the presence of organic acids like citric and malic acids, whereas only 20% are attributed to high protein content, regardless of the high concentration of cations (K + , Ca 2+ , and Mg 2+ ). Despite the pH increase in the enriched silages, its values were within the expected range for experiments with leguminous species, which show higher pH values for the stabilization of the fermentation process (EPIFANIO et al, 2016).

he aim of this study was to evaluate fermentation and chemical characteristics and the in situ degradability of sorghum silages enriched with dried Leucaena. The experiment was conducted as completely randomized design with four treatments (0 - control silage, silage without leucaena; 10.0, 20.0, or 30.0% inclusion of Leucaena) and five replicates, totaling 20 experimental units. The inclusion levels of leucaena influenced (P 0.05), with all silages having values above 90%. Gas loss decreased (P < 0.05) as the level of leucine increased in sorghum silage. A linear increase was observed for dry matter (P ? 0.0001) and crude protein (P = 0.0008) contents in response to Leucaena inclusion. There was a linear (P < 0.05) linear effect on neutral detergent fiber, hemicellulose and acid detergent fiber. As leucaena inclusion levels increased, for each 1% inclusion a reduction of 0.179 was observed; 0.059 and 0.119% for the values of neutral detergent fiber, hemicellulose and acid detergent fiber respectively. The inclusion of leucaena influenced (P < 0.05) the increase of silage lignin levels, probably due to the higher lignin content of the legume. The soluble fraction (a) of the silages increased along with the Leucaena inclusion levels, with highest values observed at the inclusion of 20 and 30% of the legume, respectively. Potential degradation (A) increased linearly with the levels of Leucaena added to the silage; the highest value for this variable was observed at 30% inclusion. Effective degradability (ED) increased up to the inclusion level of 20% (46.77%). Degradation rate (c) decreased markedly with the use of 30% Leucaena. The use of the forage part of Leucaena dried for three hours leads to reduced gas production, increased dry matter and crude protein contents, and decreased fiber contents. The degradability of dry matter increases up to the inclusion level of 20%.

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.

“…An alternative little explored is the use of legumes in the production of silage, it is known that the addition of legumes into grass silage improves the quality of the ensiled mass by increasing the protein content, improving nutrient digestibility, intake and aspects related to the production like weight gain and milk production, due to its high nutritional value (Epifanio et al, 2016;Santana, Cisneros, Martínez, & Pascual, 2015). It is possible to ensile almost all types of forage; however, few species meet the requirements of quantity and quality, and it is important to analyze which species are more economically and nutritionally desirable.…”

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.
