“…Nevertheless, recent studies have indicated that when fermentation is controlled, the use of sugarcane in well-balanced diets provides satisfactory results in animal production (Pedroso et al, 2006;Queiroz et al, 2008;Mendes et al, 2008).…”

-The objective of the present study was to evaluate the performance of beef cattle in feedlots fed diets containing either whole-crop maize silage or sugarcane silage, and with different formulations. Five diets were evaluated:MSF -diet containing whole-crop maize silage, with fixed formulation during feedlot period; MSV-diet containing wholecrop maize silage, with variable formulation according to feedlot phase; SCSF -diet containing sugarcane silage with fixed formulation; SCSV-diet containing sugarcane silage, with variable formulation; SCSV/MSV-SCSV diet in initial half of fedlot and MSV diet in final half of feedlot period, respectively. It was used a complete random experimental design, with five treatments and three replicates (pens). It was used 285 steers at 36 months of age, with an initial body weight of 362.4 kg. Diets with whole-crop maize silage promoted greater intake of dry matter (10.5 kg and 2.4% BW) compared with diets containing sugarcane silage (10.1 kg and 2.3% BW). There was no effect of the silages on average daily gain (1.348 kg/animal/day) and live weight at slaughter (481.2 kg BW). SCSV/MSV diet promoted the worst feed conversion (8.0 kg DM/kg BW). Animals fed diets composed of whole-crop maize silage presented greater weight of hot carcass, of carcass yield and subcutaneous fat thickness (262.1 kg, 54.1% and 6.2 mm) compared with the animals fed sugarcane silage (252.5 kg, 52.7% and 4.8 mm).The use of sugarcane silage in diets for finishing beef cattle is feasible and the adjustment of formulation during confinement period does not influence performance of the animals. Replacement of sugarcane silage by whole-crop maize silage during the feeding period affects negatively feed conversion.

“…The application rate of the inoculants and the addition of fibrolytic enzymes did not affect animal performance (P>0.119). An earlier study carried out by Pedroso et al (2006) reported an increase of 31.9% in the ADG of Holstein heifers fed a TMR that contained sugarcane inoculated with L. buchneri 40788 (1.24 kg/d) compared with animals fed a TMR that was based on untreated silage (0.94 kg/d). In the current trial, silage DM was determined by oven drying; thus, the DM content may have been underestimated, leading to underestimation of DMI and overestimation of feed efficiency (McDonald and Dewar, 1960;Daniel and Nussio, 2011).…”

“…Ensiling sugarcane under laboratory conditions normally decreases DM concentrations (Schmidt, 2009). In farm-scale silos, however, this effect is not always evident if the losses of DM and moisture occur at similar magnitudes (Pedroso et al, 2006). Furthermore, most of the volatile compounds may have been lost during the oven-drying of the silage samples in the laboratory (McDonald and Dewar, 1960;Daniel and Nussio, 2011), thus leading to underestimation of the DM content and reinforcing the extensive occurrence of water loss from the silo working face.…”

-Lactobacillus buchneri 40788 and the fibrolytic enzymes β-glucanase and xylanase were applied to chopped sugarcane to study their effects on the nutritive value of silage. Sugarcane was mechanically harvested after 14 mo of growth and treated without (control) or with L. buchneri at a theoretical application rate of 5 × 10 4 cfu/g, 1 × 10 5 cfu/g, or 1 × 10 5 cfu/g plus enzymes. Forage was packed into farm-scale bag silos (40 t/silo) and stored for 92 d. Fifty-six bulls (32 Nellore and 24 Charolais × Nellore) were housed in 20 collective pens and fed diets comprising (dry matter [DM] basis) 458 g/kg sugarcane silage and 542 g/kg concentrates for an 84-d period. Treated silages had higher concentrations of acetic acid and lower concentrations of ethanol. Total mixed rations (TMR) containing inoculated silages exhibited significantly lower neutral detergent fiber (NDF) concentration and, consequently, higher in vitro DM digestibility (IVDMD). Thus, animals fed TMR containing treated silages spent less time chewing per day and per kilogram of DM intake (DMI), even at higher DMI levels. Nonetheless, the intake of NDF was similar across treatments (0.77 to 0.79 kg/100 kg BW) but markedly lower than the value reported for traditional forages. Average daily gain was significantly greater for animals fed TMR based on inoculated silages due to the higher DMI (14% on average) and the higher energy content of the diets, as indicated by the higher feed efficiency (12% on average). The dose of inoculants used and the addition of fibrolytic enzymes had no significant effects on silage parameters or animal performance. Therefore, inoculation of L. buchneri during sugarcane ensilage can alter the fermentation pattern by increasing acetic acid yield, reducing silage nutrient losses, and improving feed efficiency by bulls.

“…Se ha observado en investigaciones similares (Pedroso et al, 2005(Pedroso et al, , 2006(Pedroso et al, , 2007Lomelí, 2008;Rocha et al, 2009) que al adicionar el 3% de inóculo y aditivo tuvo una disminución en la digestibilidad de la materia seca atribuyéndolo a una probable baja en el pH del ensilado por acción de los lactobacilos homolácticos contenidos en el inóculo quienes al producir una gran cantidad de ácido láctico inhiben la actividad de las bacterias heterolácticas presentes en el proceso de fermentación del ensilado, lo que disminuye el uso de los carbohidratos presentes en la caña de azúcar y baja la probable predigestión que se da, y por tanto, la digestibilidad de la materia seca; los resultados obtenidos en esta investigación apoyan que efectivamente hay una predigestión de los nutrientes de la caña ensilada y que esta, se ve favorecida al adicionar el inóculo y aditivo a 1% ya que mejora sustancialmente la digestibilidad de la materia seca, en comparación con la ensilada sin aditivo, además, la inclusión de aditivos a esta concentración ayuda significativamente a mejorar la calidad del ensilado de caña de azúcar fomentando la fermentación láctica y obteniendo así un forraje de mejor calidad y con un mayor impacto en la producción animal.…”

Publicado como ARTÍCULO CIENTÍFICO en Ciencia y Tecnología 5(1): 13-16. 2012Resumen E l objetivo de este estudio fue evaluar el efecto de la adición de un inóculo y un aditivo artesanal, sobre la degradabilidad in situ de la materia seca (MS) en el ensilado de caña de azúcar (ECS). Los tratamientos fueron: T1) ensilado de caña de azúcar sin inóculo ni aditivo, y T2) ensilado de caña de azúcar con 1% de inóculo y el 1% de aditivo. El inóculo artesanal está compuesto por 10.0% melaza, 1.0% de yogurt natural, 5.0% pollinaza, 0.5% urea y 83.0% de agua; y el aditivo esta formulado con 1.0% urea, 0.1% sulfato de amonio y 0.25% fósforo. Dos vacas Holstein con fístula ruminal permanente (PV 650±50 kg) que fueron utilizados por un período de 15 d para la adaptación a los materiales experimentales y 3 d para la recolección de muestras. Hubo diferencias (p≤0.05) entre tratamientos en la digestibilidad in situ de la MS. T2 muestra un mayor porcentaje de MS en comparación con el tratamiento testigo o T1; estos resultados podrían explicarse porque el inóculo causa una fermentación previa de los nutrientes de la caña de azúcar durante el proceso de ensilaje. El uso de un inóculo y el aditivo en el ensilaje de caña de azúcar cambia la desaparición ruminal de la MS.Palabras clave: Ensilado de caña de azúcar, digestibilidad, forraje, el rumen. AbstRActT he objective of this study was to evaluate the effect of adding an inoculums and an additive handmade in sugarcane silage (SCS) on in situ degradability of dry matter (DM). The treatments were T1) sugarcane silage without inoculum nor additive; T2) sugarcane silage with 1.0% inoculum and 1% additive. The inoculum made up with 10.0% molasses, 1.0% of natural yogurt, 5.0% chicken manure, urea 0.5% and 83.0% water; and the additive was formulated with 1.0% urea, 0.1% de ammonium sulfate and 0.25% phosphorus. Two Holstein cows fitted with rumen cannula (LW 650±50 kg) were used by a period of 15 d for adaptation to experimental materials and 3 d to collected samples. There were differences (p≤0.05) between treatments on in situ digestibility of DM. T2 shows higher percentages of DM compared with the treatment control or T1 in all incubation times; these results could be explained because the inoculums causes a previous fermentation of nutrients of sugarcane during the silage process. The use of an inoculum and additive on sugarcane silage changes the ruminal disappearance of DM.
