“…Acid detergent fiber (ADF) behaved similarly to NDF, because Leucaena had a lower concentration of the former component than did sorghum, leading to the dilution effect. Pereira et al (2004) observed a similar response in a study on the effect of adding Leucaena forage to corn silages (10.0, 20.0, 30.0, and 40.0% inclusion). The lignin content showed the opposite effect, increasing as the levels of Leucaena added to the silage were increased.…”

“…It is thus clear that Leucaena addition had a positive effect on the crude protein content of the silages. According to Pereira et al (2004), in the fermentation process, a small part of the protein is degraded to non-protein nitrogen. This degradation may be potentiated when a crop with low dry-matter and soluble-carbohydrate content and high buffer capacity is ensiled.…”

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%.

“…Other studies in the literature (Pereira et al, 2004) also demonstrated, in the Leucena plants, average levels of 27% of dry matter with a sample composed of leaves and branches. The composition of this material, in addition to the edaphoclimatic conditions inherent to the species itself, can be one of the factors that determine the amount of water.…”

-The objective of this study was to characterize the nutritional value of forage legumes Mimosa caesalpiniifolia (Benth.), Bauhinia cheilantha (Bong.) and Leucaena leucocephala (Lan.) and evaluate the anatomy of plants incubated and not incubated in the rumen. The experiment was conducted from September 2007 to November 2008. The experimental plot consisted of three useful plants, totaling three plots per block, and four repetitions. Plants were cut at 1 m height at intervals of 70 days; samples of leaf plus stem with a diameter smaller than 4 mm were collected for determination of dry matter, crude protein, neutral detergent fiber, acid detergent fiber, insoluble protein bound to acid detergent fiber and in vitro dry matter digestibility. The anatomical characterization occurred through the analysis of the proportion of plant tissue nonincubated and incubated in the rumen for a period of 48 hours. The legumes had high crude protein, with an average of 26.1% to Leucena, 22.4% to Sabiá and 18.5% to Mororó, and low levels of in vitro digestibility of dry matter, with an average of 47.3% to Leucena, 42.8% to Mororó and 37.2% to Sabiá. In the leaf blade of Sabiá plants, much lignified tissues that differed from plants of Leucena and Mororó were observed. The degradation process was more visible in the leaves of the Leucena, Sabiá and Mororó plants. The degradation was more pronounced in the spongy parenchyma, leaving the incubated material intact. The average proportion of the epidermis in the incubated and not incubated leaves was 15.8 and 16.4% in Leucena, 16.8 and 19.2% in Mororó and 27.2 and 25.5% in Sabiá, respectively. There are differences in the digestion and nutritional value of leaf tissues of the evaluated legumes.

ResumoEste experimento foi realizado com o objetivo de avaliar o efeito da adição da leucena (Leucaena leucocephala) sobre os teores de proteína bruta e de minerais na silagem de capim-elefante (Pennisetum purpureum Schum. cv. Napier). O delineamento experimental foi inteiramente ao acaso, com três repetições e três tratamentos: T1) 100% de capim-elefante cv. Napier; T2) 80% de capim-elefante cv. Napier + 20% leucena cv. BRA 1911 e T3) 60% de capim-elefante cv. Napier + 40% leucena cv. BRA 1911. A adição de 20% e de 40% da leucena cv. BRA 1911 aumentou significativamente (P<0,05) os teores de proteína bruta da silagem de capim-elefante de 4,04% para 6,54% e
