“…Numerous studies have demonstrated that supplementing molasses could promote higher voluntary intake, rumen fermentation, and feed efficiency as recently reviewed recently [19]. A recent metaanalysis has shown that molasses supplementation increased DMI up to 7.1% and increased NDF digestibility by 2-3% [20], which corroborated the results of this study. An improvement in daily intake by 14.2% and milk production by 3.7% of early lactating dairy cows was also reported by supplementing diets with molasses at 1 kg per animal/d [21].…”

Objective: This experiment aimed to assess natural growth enhancers supplementation on nutrient metabolism and production performance of Ongole grade cattle.Methods: The solid growth enhancer (GE) was formulated to contain highly soluble energy sources (molasses), nitrogen (urea), bypass protein (dried-Leucaena leaves and soybean meal), polyunsaturated fatty acids (fish oil), phytonutrient-rich source (T. catappa), and mineral premix. In total, 25 Ongole grade cattle at 1-1.5 years in age averaged 150 ± 12 kg of initial body weight were distributed to receive five dietary treatments as follow: P0 = basal diet; P1 = P0 + 5 g/kg BW0.75 GE; P2 = P0 + 10 g/kg BW0.75 GE; P3 = P0 + 20 g/kg BW0.75 GE; P4 = PO + 30 g/kg BW0.75 GE, respectively, (5 replicates per treatment). The experiment lasted 10 months.Results: GE supplementation at 5g/kg BW0.75 (P1) significantly increased daily gain and final BW compared to P0 (P<0.05). Voluntary intake for dry matter, crude protein, and total digestible nutrient increased for cattle fed diets containing GE (P<0.05) compared to P0 but no difference among supplementary levels (P>0.05). Digestibility of DM and CF were significantly higher at P1 t (P<0.05) while N retention was highest on P1 and P2 and P0 was the lowest (P<0.05). Cattle fed with P1 and P2 treatments excreted higher allantoin and uric acid thus produced higher microbial protein synthesis than other treatments (P<0.05).Conclusions: In conclusion, dietary GE increased nutrient density of the ration and supplementation at 5g/kg BW0.75 could increase voluntary intake and nutrient utilization, and thus increased performance parameters of Ongole grade cattle.

El objetivo de este trabajo fue estudiar las variaciones diurnas en la composición química y la fermentescibilidad ruminal en una amplia variedad de forrajes (A. sativa, L. multiflorum, L. perenne, L. híbrido, B. auleticus, M. sativa, T. pratense, T. repens, T. alexandrinum, L. corniculatus, L. pedunculatus, L. tenuis, C. intybus, P. dilatatum, P. notatum, P. plicatulum, P. lanceolata, S. sudanense). Se muestrearon treinta parcelas de diferentes especies en estado vegetativo a las 09:00, 13:00 y 17:00 horas del mismo día (tratamientos). Las muestras fueron sometidas a análisis químicos y a una prueba de producción de gas in vitro. Los volúmenes de gas se ajustaron a un modelo logístico de dos compartimentos con una única fase de latencia. Para el análisis estadístico se utilizó un modelo mixto, considerando el momento de corte como efecto fijo y el grupo botánico y la estación como aleatorios. La concentración de azúcares solubles en agua y la relación azúcares solubles/N aumentaron a lo largo del día, mientras que los niveles de fibra en detergente neutro (NDF) y N disminuyeron. Esto provocó una disminución del tiempo de latencia de la mañana a la tarde. El contenido de fibra se asoció con una fase de latencia más larga, un mayor volumen de lenta producción y tasas de fermentación más lentas. Las pasturas cortadas en la tarde mostraron un inicio más temprano de la fermentación ruminal asociado a menor concentración de fibra y mayor concentración de azúcares solubles. 2.14.0.0
