“…KP has a total digestible nutrient (TDN) value equivalent to rolled corn and a slow in situ digestion rate (Hada et al, 2016). Therefore, KP may be a suitable alternative to not only roughage (Izumi et al, 2019; Maeda, Kawasumi, et al, 2019) but also to concentrated feed (Kido et al, 2019; Kim et al, 2019; Maeda, Nishimura, et al, 2019; Nishimura et al, 2019). In addition, recent studies suggested that KP supplementation in concentrated feed for Holstein cattle could suppress the decline in ruminal pH (Nishimura et al, 2019), resulting in reduced ruminal lipopolysaccharide (LPS) activity (Kim et al, 2019; Nishimura et al, 2019).…”

We investigated the effects of wood kraft pulp (KP) feeding on feed digestibility and rumen fermentation of Japanese Black (JB) steer in the middle fattening stage. The feeding experiment was carried out a replicated 3 × 3 Latin square design using six JB steers (16.2 ± 0.8 months of age). Steers were fed rice straw and three concentrated feeds: commercial formula feed (control), formula feed containing 7.5% KP on a dry matter (DM) basis (7.5% KP), and formula feed containing 15% KP on a DM basis (15% KP). Feed digestibility and rumen fermentation parameters were recorded for 3 days during the measurement period, after an adaptation phase of 11 days. There was no significant difference in DM intake per day among diets. A slightly higher digestibility of neutral detergent fiber was observed in steers fed 15% KP, compared with those fed other diets (P = 0.059). The butyric acid ratio in rumen fluid was higher in steers fed KP diets than in steers fed control (P = 0.083). The average ruminal pH was unaffected by KP diets. This study suggests that replacing 15% of concentrated feed with KP has little effect on feed digestibility and rumen fermentation in JB fattening steer.

“…However, this factor was not enough to cause physical limitations and reduce the DM intake for the diets supplemented with babassu cake, possibly due to the physical characteristics of the babassu cake (i.e., the small size of its particles). This resulted in the low effectiveness of the fiber in the rumen; it is likely that the potentially degradable fractions were quickly digested by the sheep after ingestion, thus preventing a filling effect (Izumi, Tamura, Fujii, Nakatsuji, & Morita, 2018). The characteristics of the babassu cake made the degradation process more efficient by ensuring sufficient contact surfaces for the colonization of microorganisms and reducing the retention capacity of these particles in the rumen (Kammers & Allen, 2011;Gomes et al, 2012).…”

This study evaluated the use of babassu cake as a replacement for soybean meal and pineapple byproduct silage as roughage in the diets of feedlot sheep. Ten rumen-fistulated sheep were used and distributed in an experimental design consisting of two 5 x 5 Latin squares. Babassu cake replaced soybean meal at four concentration levels (0, 26.66, 53.33, and 80%), and pineapple byproduct silage was used as roughage. A treatment was also evaluated in which elephant grass silage was used as roughage and corn and soybean meal were used as the concentrate. No effect of babassu cake as a replacement for soybean meal on dry matter intake, neutral detergent fiber, or crude protein was observed. Higher babassu cake replacement levels in the diets resulted in linear reductions in the digestibility of the dry matter, neutral detergent fiber, organic matter, nonfiber carbohydrates and total carbohydrates. For the digestibility of the crude protein, no effect was observed after the addition of babassu cake. The replacement levels of the babassu cake had no effect on the intake and retention of the daily nitrogen, ammonia nitrogen and ruminal pH. Babassu cake could replace soybean meal at concentrations of up to 80% when the roughage source was pineapple byproduct silage. Compared with elephant grass silage, pineapple byproduct silage improves nutrient intake and digestibility and nitrogen intake, retention, and absorption without compromising the ruminal pH or ammonia nitrogen of feedlot sheep.

“…Nishimura et al (2019) evaluaron la inclusión de pulpa de papel (12%) en la dieta de vacas lecheras, como remplazo del 50% del maíz de la ración y no encontraron diferencias significativas en el Consumo de Materia seca (CMS) respecto al tratamiento control. Maeda et al (2019) incluyeron 12% de pulpa de papel (Kraft) en dietas de novillos de engorde, sin evidenciar diferencias significativas en el CMS respecto al grupo control (concentrado y forraje), mientras queIzumi et al (2019), al remplazar el ensilaje de maíz con la inclusión de pulpa de papel (Kraft) hasta un 57% en dietas en vacas lecheras, encontró una reducción en el CMS, indicando que la inclusión de altos niveles de este tipo de materiales en la ración de los rumiantes, afecta el CMS.…”

Las variaciones climáticas pueden limitar la disponibilidad y la calidad de los forrajes. Se estudió un subproducto del papel (SIP) como alternativa a los forrajes en la ración de los bovinos. Se analizaron 12 muestras de SIP, para determinar su composición nutricional y degradabilidad ruminal. La aceptabilidad (1,07kg MS) por los bovinos de los SIP solo o en mezcla, se evaluó en 12 novillas Holstein, asignadas a dos cuadrados latinos, cada uno con tres tratamientos y dos réplicas. En el primer cuadrado, los tratamientos fueron SIP solo (T1); SIP+glicerol (T2) y SIP+melaza (T3). En el segundo, los tratamientos fueron SIP+suplemento comercial (SC) (T4); SIP+SC+glicerol (T5) y SIP+SC+melaza (T6). Los SIP presentaron bajos contenidos de PC (1,5±0,14%) y altos niveles de FDN (56,9±6,17%) y cenizas (53,3±1,98%) y una DIVMO (47,7±5,8%) media. Las concentraciones de P (0,045±0,006%) y K (0,023±0,03%) fueron bajas, mientras que las de Ca (13,5±0,8%), Cu (63,9±11,5%) y Fe (1365±189ppm) fueron altas. La tasa de desaparición de la MS del SIP fue de 11,8%*h-1; la fracción soluble (a), 14% y la fracción potencialmente degradable y no soluble (b), 46,6%. La aceptabilidad del SIP fue mayor, cuando se ofreció en mezclas (T1 vs T2-T3; p<0,05) y con concentrado y melaza (T4-T5 vs T6; p<0,05). La variación en la calidad composicional del SIP fue menor para la mayoría de nutrientes y su calidad baja, debido a una digestibilidad media, una baja PC y altas cenizas. Además, su aceptabilidad fue pobre cuando se suministró sola, pero mejoró con el uso de palatabilizantes o SC.
