Abstract Corn stover (CS) is an agricultural by-product widely used in the ruminant feeding systems, despite its poor nutritional value and digestibility. Although treatments such as alkalinization, pelleting and extruded have been evaluated to improve its digestibility, the use of those treatments is limited. An alternative might be the use of EM (cocktail of mainly lactic bacteria), although there is no information about the optimal dose to improve DM digestibility of CS. On the other hand, there are agroindustrial byproducts such as milk whey and molasses that can be used as energy sources for ensiling. The objective of this study was to evaluate the level of EM® and the type of energy substrate on in vitrodry matter digestibility (IVDMD) and pH of CS silage. Microsilos were elaborated in plastic bottles, which were assigned to a completely randomized design with factorial arrangement 4 (levels: 0, 0.5, 1.0 and 1.5 ml/kg as feed of EM®) × 2 (energy source:milk whey or molasses, 15%), with five repetitions each. Results were analyzed using the GLM procedure of SAS. Orthogonal polynomials were tested to determine linear and quadratic effects of EM® dosis. Interaction of dose × energy source was observed (P < 0.05). The highest IVDMD and lowest pH was observed with addition of 0.5 mL and 1 mL of EM® and milk whey. IVDMD linearly increased and pH was reduced (P < 0.05) with the increasing levels of EM®). It is concluded that addition of EM® at doses of 0.5 to 1 mL / kg DM improved IVDMD and that milk whey is the best source of energy for the ensiling of CS.

Abstract The objective of the study was to evaluate the effect of corn stover silages with two sources of energy (cane molasses or milk whey) and EM (effective microorganisms, 1 mL/kg DM) on the digestibility of nutrients and rumen fermentation. We hypothesized that inoculation with EM (lactobacillus spp and Rhodopseudomona palustris and Saccharomyces cerevisiae) in the silage process of corn stover coud improve the in vivo digestibility and ruminal fermentation in sheep. Six male sheep with cannula in the rumen were used in a 6 x 6 Latin square design. Experimental periods consisted of 11 d for diet adjustment followed by 5 d for collection. The animals were housed in metabolic cages, with a harness to collect faeces individually. Diets consisted of concentrate (corn grain, soybean meal, mineral salt) 55% and corn stover 45% dry basis. The treatments were: CS-AMW= Corn stover with acid milk whey, CS-CM= corn stover with sugar cane molasses, SIL-AMW= corn stover silage with acid milk whey, SIL-CM= corn stover silage with cane molasses, SIL-AMW-EM= corn stover silage with acid milk whey and EMand SIL-CM-EM= Corn stover silage with cane molasses and EM. The results were analyzed with PROC MIXED procedures of SAS. The inoculation of corn stover with EM increased (P < 0.05) the content of CP in SIL-AMW-EM and SIL-CM-EM respect CS-CM (Table 1). SIL-CM-EM increase (P < 0.05) the ruminal N-NH3 and pH (Table 2) but no effect was observed for digestibility (Table 3). However, the SIL-AMW improved (5.8%, P < 0.05) the OM digestion compared with CS-AMW. A diet with 45% corn stover silage with EM was not sufficient to improve in vivo digestibility of nutrients in sheep. This project was supported by UNAM,DGAPA, PAPIIT (IT202120)

AbstractImproving the nutrition of livestock is an important aspect of global food production sustainability. This study verified whether lactic acid bacteria (LAB) inoculant could promote ensiling characteristics, nutritive value, and in vitro enteric methane (CH4) mitigation of forage sorghum (FS) mixture silage in attacking malnutrition in Zebu beef cattle. The FS at the soft dough stage, Cavalcade hay (CH), and cassava chip (CC) were obtained. The treatments were designed as a 4 × 2 factorial arrangement in a completely randomized design. Factor A was FS prepared without or with CH, CC, and CH + CC. Factor B was untreated or treated with Lactobacillus casei TH14. The results showed that all FS mixture silages preserved well with lower pH values below 4.0 and higher lactic acid contents above 56.4 g/kg dry matter (DM). Adding LAB boosted the lactic acid content of silages. After 24 h and 48 h of in vitro rumen incubation, the CC-treated silage increased in vitro DM digestibility (IVDMD) with increased total gas production and CH4 production. The LAB-treated silage increased IVDMD but decreased CH4 production. Thus, the addition of L. casei TH14 inoculant could improve lactic acid fermentation, in vitro digestibility, and CH4 mitigation in the FS mixture silages.

Abstract Red osier dogwood (ROD) is a native shrub plant rich in phenolic compounds with antimicrobial properties. The objective of this study was to evaluate the effects of substituting barley silage with either raw ROD or ROD extract (RODE) in high-grain (HG) diet under a low media pH (5.8) on gas production (GP), dry matter (DM) disappearance (DMD) and fermentation characteristics in batch cultures. The study was a completely randomized design with 4 treatments: 1) control diet (10% barley silage and 90% barley concentrate, DM basis), control diet supplemented with 2) monensin (30 mg/kg diet DM; positive control), 3) substitution of 3% ROD or 4) 3% RODE for an equal portion of silage. Inoculum was obtained from 2 ruminally fistulated beef heifers offered the HG diet. Substrate ground (1 mm) was incubated for 24 h and the experiment repeated twice. The GP did not differ among treatments (147 ml/g DM), but the DMD differed (P < 0.02) at highest for control (69.4%), lowest for ROD (58.4%) and intermediate for other treatments (64.1%). Total volatile fatty acid (VFA) concentration (mM) tended (P< 0.08) to be lower with ROD (80.5) and monensin (80.1) than control (83.9). Acetate proportion was greater (P = 0.02) with ROD (46.2%) and RODE (46.9%) than control (42.4%) and monensin (42.3%). However, the propionate proportion was greater (P = 0.05) with monensin (32.1%) than other treatments (averaged 30.1%). Consequently, acetate to propionate ratio (A:P) of ROD (1.52) and RODE (1.56) was higher than monensin (1.32; P < 0.01) and control (1.44; P < 0.08). Differences in variables measured between ROD and RODE were minimal. These results indicated that the decreased DMD along with increased A:P with addition of ROD or RODE suggests that both ROD and RODE may be beneficial to HG fed cattle for reducing risk of rumen acidosis without negatively impacting fibre digestion.

This study was done to determine the effects of bale sizes of bio-ammoniated rice straw on its nutrient quality and in vitro digestibility. Rice straw were bio-ammoniated by adding 2 g urea and 1 g probiotic/kg DM. By following a completely randomized design, rice straw was baled in 3 different weights (15, 25, and 35 kg) with six replications for each treatment, and then stored for 3 weeks. In the end of the week 3, bales were opened, aired, and then sampled for proximate analysis (dry matter, organic matter, crude protein, and crude fiber) and digestibility by in vitro gas production method. Using analysis of variance method, the proximate data showed that greater the bales size (15, 25, and 35 kg) increased crude protein (7.59, 7.86, and 9.95%, respectively; P<0.05) and decreased crude fiber contents (24.1, 22.1, and 18.8%, respectively; P<0.05). By increasing the size of bales also increased a, b, and c fractions (-0.79, 0.26, and 0.82 mL/100 mg DM; 20.2, 18.2, and 17.6 mL/100 mg DM; 0.012, 0.014, and 0.019 mL/h, respectively; P<0.05) as well as gas production (11.4, 11.5, and 13.8 mL/100 mg DM, respectively; P<0.05). It can be concluded that packing bio-ammoniated rice straw in 35 kg bale is the most effective way in increasing nutrient quality and digestibility of rice straw.

Midas marrowstem kale (Brassica oleracea L.) was grown in different row width associations with United 106 corn (Zea maize L.) in two studies and ensiled in different moisture blends with corn stover in another. Highest dry matter yields were obtained where a single row of kale was grown at 30 cm to the side of a corn row. This combination also provided the lowest moisture content feed and the highest in vitro digestibility and crude protein content. Changing the corn row width had no significant effect upon yield, plant height, in vitro digestibility, kale leaf or corn ear content. Blending kale with corn stover to provide a silage of about 70% moisture increased the digestibility and protein content of the feed and provided a silage that kept well in storage.

Abstract The objective was to evaluate the effects of increasing inclusion of wet distillers grains (WDG) on in vitro ruminal and total tract digestibility in feedlot sheep. Three crossbred ruminally-cannulated male sheep were used as rumen liquid donor. Treatments consisted of isonitrogenous and isoenergetic diets, containing 0, 15, 30 or 45% WDG on DM basis (Control, 15WDG, 30WDG, and 45WDG, respectively). Diets were composed of sugarcane bagasse (20%) and the concentrate (80%) composed of soybean meal (except 45WDG), wheat meal, WDG (except Control), urea, limestone, and mineral-vitamin premix. In vitro digestibility of DM (IVDMD), NDF (IVNDFD), and CP (IVCPD) were performed using the Ankom-DaisyII fermenter. Ruminal digestibility was evaluated after 48h incubation (39°C) using twenty-five filter bags. After 48h, twelve filter bags remained into each jar to evaluate the total tract digestibility. For it, 40mL of 6N HCl and 8g of pepsin were added and incubated for another 24h. The post-ruminal digestibility was calculated by the difference between rumen and total tract digestibility. Data were analyzed using SAS software. Contrasts were used to determine the linear and quadratic effects of WDG inclusions, as well as the contrast Control × WDG treatments. The WDG inclusion linearly decreased the ruminal and total DM and CP digestibility and increased the post-rumen CP digestibility (P &lt; 0.05). When all treatments with WDG were evaluated against the Control, a significant effect was observed for IVDMD, with averages of 68.86 × 77.38%, 5.60 × 0.77% and 71.41 × 78.20%, and for IVCPD, with averages of 68.89 × 95.27%, 21.30 × 1.99% and 90.15 × 97.27%, respectively for rumen, post-rumen and total tract digestibility (P &lt; 0.05). The results indicate that inclusions of WDG at up to 45% in the diets for sheep reduce the ruminal and total DM utilization, however, promote a better post-rumen use of CP of diets.

Palm oil fiber has its potency as feed fiber source for ruminant, but contains high lignin and causes limited digestibility. This research was carried out to find the effect of soaking palm oil fiber in filtrated palm oil fruit bunch ash (FPOFBA) on in vitro digestibility. This experiment used a completely randomized design that repeated for 4times. Palm oil fruit bunch ash was mixed in water and entered into container for 24 hours within concentrations, consists of: 50, 100, 150 and 200 g/L. Moreover, this filtrate used to soak palm oil fiber for 3 hours. The processed products were analyzed for their level of lignin and crude fiber. Meanwhile, in vitro test was used to measure digestibility. It showed that soaking in filtrated palm oil fruit bunch ash gave significant effect to decrease level of lignin and crude fiber (P<0.05), and without soaking to improve digestibility of dry and organic matter compared to control treatment (P<0.05). Treatment with 150 g/L and 200 g/L using filtrated palm oil fruit bunch ash produced low level of lignin (P<0.05), as of: 17.25 and 18.53%. In contrast, within concentration of 150 g/L produced higher level of crude fiber compared to 200 g/L (46.04 vs. 43.87%). This seemed to have the same results in digestibility of dry and organic matter (P>0.05), such as 23.48 and 24.12% as well as 16.70 and 17.06 % in each. It can be concluded that soaked palm oil fiber with 150 g/L concentration of filtrated palm oil fruit bunch ash was more effective in improving digestibility.
