“…Even with a reduction in NDF and ADF (p < 0.05) with the addition of MPM in the diets, their contents have risen, since the MPM presents NDF and ADF associated with a higher DM intake according to the replacement. These results corroborate those reported by Batista et al (2006) and Rêgo et al (2011) which included MPM in elephant grass silage and observed a linear decrease (p < 0.05) in NDF and ADF of the experimental diets.…”

ABSTRACT. Eight Santa Ines sheep were assigned to two 4 x 4 Latin squares, to evaluate the effects of replacing elephant grass silage with different levels of mesquite pod meal (MDM) (15, 30 and 45% DM) on intake, apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), acid detergent fiber (ADF), neutral detergent fiber (NDF), total carbohydrates (TC) and non-fiber carbohydrates (NFC) and the nitrogen balance. There was a linear increase (p < 0.05) in the intake of DM, OM, CP, ADF, NDF, NFC and TC according to the addition of MPM to the diet. The digestibility of DM, OM and CP increased (p < 0.05) with the addition of MDM. We observed a positive linear effect (p < 0.05) for the nitrogen intake. The addition of mesquite pod meal up to 45% increased the intake of DM, NDF, ADF, CP, OM, NFC and TC but reduced the digestibility of EE and NDF. MPM at 30 and 45% propitiated a positive nitrogen balance.Keywords: forage conservation, Prosopis juliflora, silage.Farelo de vagem de algaroba em dietas de ovinos: consumo, digestibilidade aparente dos nutrientes e balanço de nitrogênio RESUMO. Foram utilizados oito ovinos da raça Santa Inês, distribuídos em dois quadrados latinos 4 x 4, com o objetivo é avaliar os efeitos da adição do farelo de vagem de algaroba -FVA (15, 30 e 45% da MS) em substituição à silagem de capim elefante sobre o consumo, digestibilidade aparente da matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra de detergente ácido (FDA), fibra em detergente neutro (FDN), carboidratos totais (CT) e carboidratos não fibrosos (CNF) e balanço de nitrogênio. Foi observado efeito linear crescente (p < 0,05) dos níveis de FVA sobre os consumos de MS, MO, PB, FDA, FDN, CNF e CT. Os coeficientes de digestibilidade da MS, MO e PB aumentaram (p < 0,05) com a adição de FVA. Observou-se efeito linear positivo (p < 0,05) para a ingestão, excreção fecal e retenção de nitrogênio, enquanto que a excreção de N na urina não variou (p > 0,05) em função dos níveis de substituição. A adição de FVA em até 45% proporcionou o aumento do consumo de MS, FDN, FDA, PB, MO, CNF e CT, mas, reduziu o coeficiente de digestibilidade do EE e de FDN. Os níveis 30 e 45% de FVA proporcionaram balanço de nitrogênio positivo.Palavras-chave: conservação de forragem, Prosopis juliflora, silagem.

“…The breakdown of stability was influenced by the addition of BP silage. The highest concentration of DM treatments made silages took longer to break aerobic stability, as higher values of DM hampered the growth of microorganism, lack of adequate moisture (BATISTA et al, 2006). The amplitude of the temperature variation of the silo was quite high in treatments with less of 15% of BP, reaching a peak of 7.2°C above the temperature at 5% inclusion, which could infer that there was intense microbial activity at this time.…”

The objective of this study was to evaluate the effect of adding palm kernel meal (BP) as an additive in elephant grass silage. The chemical qualitative and fermentation were analysed in a completely randomized design with six treatments, one with no BP (C) and six replications, where the averages of the results of days of closing and opening were analysed by regression analysis. We collected samples at the time of ensiling and after 190 days of storage for evaluation of dry matter, crude protein, carbohydrates (total, non-fibrous, water-soluble, cellulose and hemicellulose), ash, lignin and ether extract. In aerobic phase, we collected samples for pH, ammoniacal nitrogen, fungi and yeasts. The elephant grass of this experiment showed values of 13.9% DM and 8.25% CP while the BP has 77.2% DM and 16.9% CP. The inclusion of BP had inhibited the growth of fungi and yeasts. The increase in the content of BP decreased the concentration of NH3-N. Higher concentrations of BP in silage were more stable, and the stability breaks in 72 hours, while the stability of C was 19 hours. Concentrations above 15% BP had no significant variations in pH in the aerobic phase. The inclusion of palm kernel meal at concentrations 10% to 15% can be used in silage of elephant grass, inhibiting undesired fermentation and making them more stable. Concentrations above this value may affect the nutritive value of silage by high lignin content of the additive.

“…Batista et al (2006), avaliaram a inclusão da vagem de algaroba triturada na ensilagem de capimelefante e observaram aumento nos teores de matéria seca das silagens. Logo, a inclusão da vagem de algaroba (VA) triturada no momento da ensilagem poderia se constituir uma alternativa viável para aumentar o teor de matéria seca da silagem e conseqüentemente melhorar o padrão de fermentação.…”

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. Palavras-chave -Degradabilidade in situ. Ensilagem. Pennisetum purpureum. 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.
