<p>The aim of this study was to evaluate performance and in vitro digestibility of Guinea grass grown on saline soil. Yield, quality, and in vitro digestibility of Guinea grass cultivated on coastal area with crop populations of 10,000,<br />20,000, and 30,000 plants per hectare. Experiment was conducted following randomized complete block design (RCBD). Higher crop population increased fresh and DM biomass production, crude protein (CP) yield, dry matter<br />(DM) content, neutral detergent fiber (NDF), lignin, and hemicellulose content, but decreased CP content, and in vitro organic matter digestibility (OMD). The increased population had no effect on acid detergent fiber (ADF) and in vitro<br />dry matter digestibility (DMD). It could be concluded that guinea grass was recommended to be planted in saline coastal area by addition of fertilizer 20 tons/ha manure, 3 tons/ha gypsum, and 50 kg N (239 kg ZA/ha) as source of<br />nitrogen.</p><p><br />(Keywords: Forage, Salinity, Saline soil, Manure, Gypsum, Nitrogen source)<br /><br /></p>

Dry Matter Digestibility

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

Recognizing the potential and importance of cultivating improved forage crops as a means of tackling the recurrent feed shortage facing the study area, seven oat genotypes were tested in randomized complete block design with three replications across two locations for three growing seasons (2014, 2015, and 2016). The study was aimed to evaluate dry matter (DM) and digestible organic matter yield and nutrient composition of oat genotypes. The study revealed that oat genotypes responded differently for herbage dry matter (DM) and digestible organic matter (OM) yield, and quality parameters in both study locations. Averaged over the seven oat genotypes, herbage DM and digestible OM yield. recorded at Bako were higher than Boneya Boshe location across the study periods. The ash ( P  > 0.05) content did not vary among oat genotypes at both testing locations, while variation was observed for DM, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), in vitro digestibility, and metabolizable energy (ME) constituents. In general, genotypes ILRI 6710 and 5453 showed higher herbage DM and digestible OM yield. Moreover, the two genotypes are also higher in their in vitro digestibility value and ME, DM, and CP contents but relatively lower in NDF, ADF, and ADL fiber constituents, and thus, they are recommended for wider cultivation.

Fat is often fed to sheep and cattle as a means to increase dietary energy concentration. There is increasing interest in the supplementation of ruminant diets with fats and oils. However feeding fat may reduce dry matter digestibility, and feeding ruminant animals large quantities of fat (>5% of total dry matter intake) can result in a marked negative effect on fibre and dry mater intake. The aim of the present study was to investigate the effect of fat supplementation on ruminal degradation of dry matter (DM) and neutral detergent fiber (NDF) of sheep fed a tropical hay.

The objective of this study was to evaluate the nutritional traits and in vitro digestibility of silages from different corn cultivars harvested at two cutting heights. It was evaluated 11 cultivars (Dina 766, Dina 657, Dina 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, Dina co 9621 and BR 205) harvest 5 cm above ground (low) and 5 cm below the intersection of the first ear (high). It was used a random block design (three blocks), arranged in a 11 × 2 factorial scheme. Silages from plants harvested at high cutting height presented average content of dry matter significantly superior to silages from plants harvested at low height. Cultivars FO 01, AG 5011, Dina co 9621 and Dina 766 presented greater content of crude protein than cultivars C 805, P 3041 and P 3021, which presented the lowest contents of this nutrient. The raise in the cut height increased in vitro dry matter true digestibility coefficients and in vitro dry matter digestibility of silage evaluated. The increase in cut height improved nutritive value of silages by decreasing concentrations of fibrous fractions and increasing in vitro dry matter digestibility.

The aim of this study was to identify the most adequate level of calcium oxide (CaO) in the treatment of sugar cane by evaluating the chemical composition and in vitro digestibility of dry matter. The sugar cane was homogenized with CaO levels 0, 0.75, 1.5, 2.25, 3.0, 3.75 and 4.5%, in natura matter, for 24 hours. The dry matter and mineral matter increased, while the organic matter of the sugar cane decreased (P <0.05) linearly as a result of the CaO levels. The CaO had no effect on the levels of crude protein and ether extract. The phosphorus concentration remained unchanged, but there was a significant increase (P<0.05) in the calcium content. The contents of neutral detergent fiber, acid detergent fiber and cellulose decreased linearly with the levels of CaO. The average levels of indigestible dry matter and indigestible neutral detergent fiber significantly decreased with increasing levels of CaO. The results showed that the in vitro dry matter digestibility (IVDMD) was different between fresh sugar cane and sugar cane with added levels of CaO from 1.5%. The IVDMD and nutritional value of the sugar cane was improved by adding 1.5% CaO based on fresh content.

Abstract The aim of this study was to assess the effects of Zeolite (ZE, clinoptilolite) inclusion on in vitro rumen fermentation. A modified procedure from Tilley and Terry (1963) was used to determine alfalfa in vitro dry matter digestibility (IVDMD) in the presence or absence of ZE. Test tubes (n = 96) were placed in a 39 °C bath and were blocked based on hours 0, 1, 2, 4, 6, 8, 12, 24, and 48. Substrate consisted of dried alfalfa grinded through a 1mm screen using a Wily Mill. Treatments consisted of, Control (no ZE inclusion), and 0.05g ZE, for each 1 gram of alfalfa. After incubation, IVDMD was calculated 24 hours after drying period. Data was analyzed using a randomized block design. The IVDMD was found to be similar across all treatments (P &gt; 0.8464). The IVDMD was significantly different when incubated for the varying lengths of time (P &lt; 0.001). There was an IVDMD of 20.18 ± 2.89 % for the control and 18.07 ± 5.49 % for the ZE at the zero hour. The IVDMD for Control and ZE for 48 hours were 54.30 ± 1.58 % and 53. 48 ± 1.04 % respectively. To predict the IVDMD of the effects of ZE treatment on digestibility over time, the corresponding regression f(x) = 20.60 + 0.421X1 + 0.730X2 with R2 = 0.8464. In conclusion these data demonstrate that inclusion of ZE, does not influence the in vitro digestibility of alfalfa. These findings are important as previous data would indicate that inclusion of ZE may reduce cost of gain and/or influence liver abscess rates, it was uncertain if that would come at the cost of reduced digestibility of feed. These data indicate that there is likely very little to no impact on feed digestibility when ZE is included in the ration.

The use of silage has been an efficient alternative to feed supply during the shortage of roughage in dry periods, providing quality feed that is widely used in ruminant feeding. Thus, the objective of this study was to evaluate the fermentative characteristics and nutritive value of corn silage with Tamani guinea grass (Panicum maximum BRS cv. Tamani) through chemical composition, in vitro dry matter digestibility and protein fractionation. The experiment was conducted in a completely randomized design with four replications. The treatments consisted of five silages: corn; corn with 10% Tamani guinea grass; corn with 20% Tamani guinea grass; corn with 30% Tamani guinea grass; and corn with 40% Tamani guinea grass, totalling 20 experimental silos. The addition of tamani grass to silages was determined based on fresh matter. For ensiling, corn was harvested with 320 g kg-1 DM (dry matter) and Tamani guinea grass in a 30-day development cycle with 286 g kg-1 DM. After 50 days of silage, the silos were opened to analyse the fermentative characteristics, chemical composition and protein fractionation of the silage. The results showed that the addition of Tamani guinea grass in corn silage increased the pH and buffering capacity and reduced the dry matter and lactic acid concentration but did not compromise the fermentative characteristics of silages. The addition of 40% Tamani guinea grass in corn silage provided increased levels of crude protein, in vitro dry matter digestibility, protein A, B1 and C, and decreased the fractions B3 and C, which makes Tamani guinea grass an alternative to improve the quality of exclusive corn silage, resulting in better quality silage.

The aim of this study was to measure the chemical composition, microbiological profile, fermentative characteristics and the aerobic stability of the olive bagasse silages in natura and added with corn bran, soybean and rice bran in different times of sampling. The was completely randomized design in arrangement of plots subdivided in 4x3 time, with five replications. In the plots were allocated the main treatments, and in the subplots the sampling times were allocated. The fermentative characteristics was studied by determination of the dry matter (DM) content, pH and ammoniacal nitrogen (NH3-N), the microbiological by determining the populations of filamentous fungi, Clostridia, lactic acid bacteria and enterobacteria. In the nutrient profile study, the contents of mineral matter (MM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, cellulose, hemicellulose, nitrogen bound to acid detergent fiber (NIDA), nitrogen bound to neutral detergent fiber (NIDN), carbohydrate and total digestible nutrient (TDN). At the ensilage moment, it also has been determined in vitro dry matter digestibility (IVDMD) and in vitro digestibility of organic matter (IVDOM). The use of corn and rice bran provided a better fermentative profile in the studied ensilage. The pH of the silages added corn and rice bran has presented in 4.00 and 4.06 after 112 storage days, consequently. The adding of soybean bran provided the greatest CP values and non-fibrous carbohydrates (NFC) after the fermentative period, been it 131.55 g kg-1 of DM for CP and 176.28 g kg-1 of DM for NFC. The treatments without bran adding and rice bran added have demonstrated IVDOM levels of 581.12 g ka-1 od DM and 604.51 g kg-1 of DM, consequently. The studied meals improve the nutritional profile of the studied silages and are potentially usable as additives in olive bagasse silages.

Dry Matter Digestibility

Digesting forages with a prepared cellulase solution (PCS) has been shown to be a rapid method of obtaining dry matter digestibility (DMD) estimates in many species. This procedure has not been previously used to obtain DMD estimates of broadleaf birdsfoot trefoil (Lotus corniculatus L.). A broad based population consisting of 19 accessions, representing 11 countries of origin, three germplasm pools, and two domesticated cultivars of birdsfoot trefoil was evaluated. The PCS was produced from culturing Trichoderma reesei Simmons culture number QM9414. Fiber and PCS determinations were compared to an in vitro rumen fermentation (IVDMD) procedure. The fiber components measured were; neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose (HEMI). The PCS procedures involved digestion using a PCS without any pre- or post-treatment (CS), acid-pepsin digestion followed by a single-stage digestion in PCS (APCS), acid detergent solution (ADS) followed by a two-stage digestion in PCS (ADSCS), and neutral detergent solution (NDS) followed by a two-stage digestion in PCS (NDSCS). All of the fiber and PCS procedures were significantly (P ≤ 0.001) correlated with IVDMD except HEMI. The CS procedure underestimated IVDMD by 199 g kg−1; however, it had the best regression coefficient (b = 0.99), had the second best correlation coefficient (r = 0.86), and required less time than the other PCS procedures. The APCS procedure provided the best estimate of IVDMD. It overestimated the IVDMD mean of birdsfoot trefoil by only 30 g kg−1 and was the most accurate (residual standard deviation (RSD) = 22 g kg−1) approach. The CS procedure is recommended when a ranking of samples is desired and actual values of DMD are not of primary interest.Key words: Fiber digestion, germplasm, in vitro dry matter digestibility, Lotus corniculatus L., Trichodenna reesei Simmons

This research was conducted to determine the effects of selected inoculant on the silage with different wilting times. The ryes were unwilted or wilted for 12 h. Each rye forage was ensiled for 100 d in quadruplicate with commercial inoculant (Lactobacillus plantarum sp.; LPT) or selected inoculant (Lactobacillus brevis 100D8 and Leuconostoc holzapfelii 5H4 at 1:1 ratio; MIX). In vitro dry matter digestibility and in vitro neutral detergent fiber digestibility were highest in the unwilted MIX silages (p < 0.05), and the concentration of ruminal acetate was increased in MIX silages (p < 0.001; 61.4% vs. 60.3%) by the increase of neutral detergent fiber digestibility. The concentration of ruminal ammonia-N was increased in wilted silages (p < 0.001; 34.8% vs. 21.1%). The yeast count was lower in the MIX silages than in the LPT silages (p < 0.05) due to a higher concentration of acetate in MIX silages (p < 0.05). Aerobic stability was highest in the wilted MIX silages (p < 0.05). In conclusion, the MIX inoculation increased aerobic stability and improved fiber digestibility. As a result of the wilting process, ammonia-N in silage decreased but ruminal ammonia-N increased. Notably, the wilted silage with applied mixed inoculant had the highest aerobic stability.
