“…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.

“…Probably, this difference, as previously discussed, are related with protein, lignin, NDIN and ADIN contents in the silages, where the highest inclusion contents might have negatively influenced the potentially soluble fraction (b) and degradation rate (c). The DM effective degradability at 0.05 h -1 rumen passage rate was lower than the observed by Rêgo et. al.…”

This study evaluated the inclusion of increasing contents (0; 35; 70; 105 and 140 g kg-1) of dried acerola fruit (Malpighia glabra, Linn.) by-product (DABP) in the ensilage of elephant grass (Pennisetum purpureum, Schum.) considering the in situ degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose. Plastic drums with 210 L capacity were used as experimental silos. After 45 days of ensiling, silos were opened and silage samples were collected for the degradability trial and laboratory analysis. For the in situ degradability trial, was used one rumen-fistulated adult male cattle. The five by-product inclusion contents were tested in three replicates, with five incubation times, in a randomized complete split-plot design in which the contents of DABP were the treatments (plots), the different silos were the replicates and the incubation times were the sub-plots. Longer incubation times significantly increased (P < 0.05) the disappearance rates of DM, CP, NDF, ADF and hemicellulose. The effective degradability of the DM, NDF and hemicellulose was higher in the silages with 35 g kg-1 of DABP in the rumen passage rates of 0.02; 0.05 and 0.08 h-1. Dried acerola fruit by-product can be added to elephant grass ensiling up to 35 g kg-1 without reducing the effective degradability of nutrients.

“…Quando os níveis de carboidratos solúveis do material ensilado são altos, as bactérias ácido- láticas serão extremamente ativas, resultando em silagens de baixo pH e com alto conteúdo de ácido lático (PIRES et al, 2009). Os efeitos da inclusão de vagens nessa pesquisa se assemelham a média de pH (3,57) obtida por Rego et al (2011) quando da inclusão de 15% de vagens de algaroba trituradas em silagens de capim elefante.…”

RESUMO:Objetivou-se avaliar os parâmetros fermentativos e a composição química de silagens de capim elefante com adição de vagens de faveira. As vagens foram adicionadas à forragem nos níveis 8, 16 e 24% com base no peso verde, junto a tratamento controle (0%) em delineamento inteiramente casualizado. Foram quantificados os valores de pH, perdas por efluentes (PE) e perdas por gases (PG), recuperação de matéria seca (RECMS), proteína bruta (PB), fibra em detergente neutro (FDN) e detergente ácido (FDA), lignina (LIG) e nitrogênio insolúvel em detergente ácido (NIDA) e estimaram-se os valores de celulose (CEL) e hemicelulose (HCEL). Verificou-se aumento linear (P<0,05) para PG e redução de 52,23% na produção de efluente quando do tratamento de 24%, com pH mantendo-se no nível ideal (média de 3,76). Quanto à composição química da silagem, observou-se elevação dos teores de MS e PB (6,53%) quando da inclusão das vagens, com menores proporções de FDN (52,99%) e FDA (36,48%). No entanto, os teores de NIDA aumentaram quando da elevação dos níveis de vagens na silagem. As vagens de faveira são indicadas como aditivos, em até 24%, para ensilagem de capim elefante, por melhorar a qualidade da silagem, quanto à fermentação e composição química.Palavras-chave: ensilagem; fermentação; Pennisetum purpureum Schum.; Parkia platycephala Benth. ABSTRACT:The objective of this study was to evaluate the fermentative parameters and chemical composition of elephant grass silages with the addition of faveira pods. The pods were added to the forage at levels of 8, 16 and 24% on a dry matter (DM) basis, together with the control treatment (0%), in a completely randomized design. The pH, losses through effluent and gas, dry matter recovery, crude protein (CP), neutral detergent fiber (NDF), acid detergent (ADF), lignin and acid detergent insoluble nitrogen (ADIN) were quantified, and cellulose and hemicellulose were estimated. There was a linear increase (P<0.05) in losses through gas and a reduction in effluent production (1.17 kg/ton DM) at 24%, with pH remaining at the ideal level (3.76). Regarding the chemical composition of silage, an increase in DM and CP (6.53%) was observed at the highest levels of pod inclusion, with lower proportions of NDF (52.99%) and ADF (36.48%). However, ADIN levels increased with increasing pod levels in the silage (+ 6.81%). Faveira pods up to 24% are indicated as additives for elephant grass silage, as they improve silage quality, fermentation and chemical composition.
