“…Despite the DDM is lower in treatment 0%, the curve of degradation was more accentuated because the degradation was slower, that is, for the time 6 to 72 h the disappearance of DM was 26.41%, that is, 48.43% higher than the treatment of 20% of inclusion of babassu, since from the time 6 to 72 h, the disappearance of DM was 13.62%. Rêgo et al (2010), working with the inclusion of the penduncle of cashew dehydrated in silage of elephant grass, an ascending linear behavior was observed for the same time of incubation studied in the present work; 0.64% points for each 1% of inclusion of the by-product of the cashew.…”

The goal of this study was to evaluate the nutritive value and the in situ degradability of elephant grass (Pennisetum purpureum Schum) silages with addition of babassu meal (BaM). PVC silos with 0.25 m in diameter and 0.75 m in height were used. It was done by adopting a compression of 550 kg/m 3 in a completely randomized design with five repetitions. It was found that increasing linear effect (P< 0.05) on the average content of silage DM, estimating an increase of 0.74% for each unit added. The crude protein content of the silage without BaM was lower than the fresh grass. There was a linear effect on the levels of neutral detergent fiber, with an estimated reduction of 0.17% per unit added. Acid detergent fiber and lignin showed linear response to increasing levels of BaM. Disappearance of DM was significant to the extent that the material remained in the rumen, the best disappearance values were observed in the time of 72 h for all levels of inclusion and among the levels of inclusion of 20% showed the best values of the disappearance of DM at all incubation times. The bran of babassu oil improves the nutritive value, the degradation parameters and provides better conservation of ensiled mass.

“…Yet some studies describe that the presence of high lignin (Ferreira et al, 2004), tannin (Agostini-Costa et al, 2003), and acid detergent insoluble nitrogen (ADIN) contents (Ferreira et al, 2007;Rêgo et al, 2010b;Teles et al, 2010) in the cashew apple may influence the intake and apparent digestibility (AD) of these materials.…”

-This study was conducted to evaluate the intake, apparent digestibility (AD), and degradability in situ of elephant grass (Pennisetum purpureum Schum) silages containing 0, 35.0, 70.0, 105.0, and 140.0 g kg -1 by-product from dried cashew apple (DCBP) (as fed basis). A completely randomized design with four replicates was adopted. For the study of degradability in situ, one adult male cattle was used in a completely randomized design with split plots. Intake and AD of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, and cellulose were evaluated, and the digestible energy (DE) and nitrogen balance (NB) of the silages were determined. The degradability in situ of DM, CP, and NDF was also determined. Addition of DCBP provided an increase in the intakes of DM, CP, NDF, and ADF. No effects of the levels of addition of DCBP were observed on the coefficients of AD of the silages. Regarding NB, positive values were only detected in the treatment with 105.0 g kg -1 DCBP. In the analysis of the degradability in situ, the incubation periods increased the rates of disappearance of DM, CP, and NDF. However, no effect of the levels of DCBP were observed on the effective degradability of DM. The by-product from dried cashew apple can be included at up to 140.0 g kg -1 in silages of elephant grass, but the high contents of acid detergent insoluble nitrogen may compromise the use and availability of nitrogen to the animals.

Resumo -Esta pesquisa foi realizada visando-se avaliar a degradação ruminal da matéria seca (MS), proteína bruta (PB) e fibra em detergente neutro (FDN) de silagens de capim-elefante colhido aos 70; 90 e 110 dias após rebrota, com inclusão de 0; 5; 10 e 15% de vagem de algaroba triturada, com base na matéria natural, em delineamento inteiramente casualizado arranjado em parcelas subdivididas. Amostras de cada silagem foram incubadas no rúmen de duas vacas Jersey por 3; 6; 12; 24; 48; 72 e 96 h, sendo os saquinhos referentes ao tempo zero apenas lavados em água para determinação da fração solúvel. Não houve interação (P > 0,05) tempo de incubação x inclusão de vagem de algaroba x idade de corte para degradabilidade da MS, embora tenha ocorrido interação destes fatores para degradabilidade da PB e FDN. A maior degradabilidade efetiva (DE) da MS (42,54%) foi observada para 15% de inclusão de vagem de algaroba. A DE da PB foi maior (69,04%) para silagem de capim-elefante com 70 dias de idade com 15% de vagem de algaroba. A inclusão de vagem de algaroba triturada à silagem de capim-elefante melhora a degradabilidade da MS, PB e FDN, enquanto o avanço da idade após rebrota resulta em redução destes parâmetros.

Prosopis juliflora.Abstract -This research was carried out to evaluate the ruminal degradation of dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of silages of elephant grass (Pennisetum purpureum) cutting in 70; 90 and 110 days after regrowth with inclusion of 0; 5; 10 and 15% of mesquite (Prosopis juliflora) meal, based on natural matter in a completely randomized design, in split plot arrangement. Samples of silages were incubated in the rumen of two Jersey cows for 3; 6; 12; 24; 48; 72 and 96 h, and the bags at time "zero" were only washed with water to determine the soluble fraction. There was not interaction (P > 0.05) incubation time × inclusion of mesquite pods × cutting age of the grass for DM degradability, there was only interaction (P < 0.05) between these factors for CP and NDF degradability. The most effective DM degradability (42.54%) was observed for 15% inclusion of mesquite pods. The effective CP degradability was higher (69.04%) for elephant grass silage with 70 days after regrowth with 15% of mesquite pods. The inclusion of mesquite pods in elephant grass silages improve DM, CP and NDF degradability, while increment of the age after regrowth result in reduction of this parameters.
