Dry matter yield, percent dry weight, in vitro digestible dry matter, in vitro digestible organic matter, neutral detergent fiber, acid detergent fiber, ash and hemicellulose contents were determined for spring- and fall-sown common wheat, barley, rye and triticale and spring-sown durum wheat and oats for the period from late boot to maturity. Differences among cultivars and stages of maturity were significant for all parameters. These differences were accompanied by stage of maturity interactions. Consideration of the interrelationships among these parameters revealed that level of in vitro digestible dry matter was reflected in measures of acid detergent fiber and ash or percent dry weight. Further analyses indicated that differences in digestibility due to stage of maturity were primarily reflected by changes in ash or percent dry weight, while differences in digestibility among cultivars were mainly attributable to differences in acid detergent fiber.

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.

The objective of this study was to evaluate the agronomic characteristics, bromatological-chemical composition and digestibility of 11 corn cultivars (Zea mays) harvested at two cutting heights. Cultivars D 766, D 657, D 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, CO 9621 and BR 205 were evaluated when they were harvested 5 cm above ground (low) and 5 cm below the insertion of the first ear (high). The experiment was designed as random blocks, with three replicates, arranged in an 11 x 2 factorial scheme. Cultivars presented similar productions of forage dry matter and grains. Percentages of stalk, leaf, straw, cob and kernel fractions were different among cultivars, as well as dry matter content of the whole plant at harvest. Considering the whole plant, only the contents of gross energy, nitrogen in neutral detergent fiber, and in vitro neutral and acid detergent fiber digestibility did not differ among cultivars. Increase on the cutting height improved forage quality due to the reduction of stalk and leaf fractions and contents of cell wall constituents.

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.

An experiment was conducted to evaluate the dry matter yield and quality performance of Maralfalfa forage obtained at six harvest intervals (HI; 40, 50, 60, 70, 80, 90 d) on three dairies in northern Puerto Rico during the long day season. The 40-day harvest interval was significantly (P < 0.05) inferior in dry matter yield to those of 60, 80, and 90 days; no significant (P < 0.05) differences in yield were observed among intervals of 40, 50 and 70 days. The 40-day interval showed the highest forage quality as indicated by crude protein content, digestibility in vitro of dry matter and neutral detergent fiber, and estimated net energy, index of relative forage quality and theoretical milk production. Although significant (P < 0.05) differences were observed in some of these criteria between 40- and 50-day harvest intervals, the latter maintained a good nutritional value in contrast to drastic losses in quality observed with the longer harvest intervals under study. The simple regression equations between digestibility in vitro of dry matter and of neutral detergent fiber versus harvest interval showed a decrease in digestibility of 2.7 and 3.0 percentage points for each additional 10 days of harvest interval, respectively.

The objective of this work was to evaluate the pH, chemical composition, minerals, vitamins, and in vitro rumen fermentation characteristics of silage prepared with lucerne, sweet maize stalk (MS), and their mixtures. Freshly chopped lucerne and MS were combined in ratios of 100:0 (M0, control), 80:20 (M20), 60:40 (M40), 40:60 (M60), 20:80 (M80), and 0:100 (M100) on a fresh matter basis. Each treatment was prepared in triplicate, and a total of eighteen silos were fermented for 65 days. After 65 days of fermentation, the pH values in M0, M20, M40, M60, M80, and M100 silages were 5.47, 4.84, 4.23, 4.13, 3.79, and 3.61, respectively. As the MS proportion in the mixtures increased, silage K, Ca, P, Na, Fe, and Cu concentrations linearly decreased (p < 0.001) and so did vitamins B5 and K1 and α-tocopherol. In vitro rumen dry matter and organic matter degradability, pH, ammonia, total volatile fatty acid, and gas production linearly decreased (p < 0.01), while neutral detergent fiber concentration linearly increased (p < 0.001), with increasing proportion of MS. The in vitro dry matter and organic matter degradability rapidly decreased when the MS percentage was ≥60%. In conclusion, the M40 silage is the most suitable for livestock utilization in local forage production considering the balance of silage pH, nutritional quality, and in vitro ruminal fermentation characteristics.

ABSTRACT The aim of this study was to investigate the effect of odontoplasty on apparent digestibility of diet for horses, consumption time, and particle size of feces. Nine horses were used, aged 14.5±3.3 years and weightng 531±38.7kg. The diet consisted of 1.5% of live weight (LW) in Tifton 85 hay and 0.75% of LW in concentrate for both assays. The experiment consisted of two tests of apparent digestibility using the method of total collection, before and after the odontoplasty, where the consumption time of hay and concentrate was also evaluated and the particle size of the feces was analyzed. An effect (P<0.05) of odontoplasty on the apparent digestibility coefficients of dry matter, organic matter, crude protein, neutral detergent fiber and acid detergent fiber was observed. Effect of the consumption time for the concentrate (P<0.05) was observed, but not for the forage (P<0.05). There was more retention (P<0.05) of the fecal particles in the sieves of bigger granulometry. The odontoplasty increases the digestibility of dietary nutrients and feces particle size, without changing feces quality. Animals after the procedure have shorter concentrate consumption time.

Abstract: The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein contents. Conversely, there was a reduction in the nonfiber carbohydrates concentration and in in vitro dry matter digestibility for the re-ensiled material. All changes were explained by the higher-effluent production and DM loss of re-ensiled material that was subjected to two compactions. Microbiology was not altered by the treatments. The use of inoculant altered ash content, but it did not influence other parameters. In contrast, re-ensiling after 36 hours of aerobic exposure caused a reduction in the nutritive value of corn silage and accentuated the DM losses.

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

Lynch, J. P., Prema, D., Van Hamme, J. D., Church, J. S. and Beauchemin, K. A. 2014. Fiber degradability, chemical composition and conservation characteristics of alfalfa haylage ensiled with exogenous fibrolytic enzymes and a ferulic acid esterase-producing inoculant. Can. J. Anim. Sci. 94: 697–704. This study investigated the effects of two fibrolytic enzyme products, applied at baling alone or in combination with a ferulic acid esterase-producing bacterial additive, on the ensilage dynamics, chemical composition and digestibility of alfalfa haylage. Five replicate wrapped bales were produced with one of five treatments, including an untreated control, and one of two fibrolytic enzyme products (EN1 and EN2) applied either alone or in combination with a ferulic-acid producing bacterial additive (FAEI). No effect of treatment was observed on the neutral detergent fiber (NDF) (P=0.889) or acid detergent fiber (ADF) (P=0.065) concentrations of haylage after ensilage, but haylage produced using fibrolytic enzyme products underwent greater (P<0.018) increases in temperature following exposure to aerobic conditions. Haylages produced with fibrolytic enzyme products had a greater (P<0.001) in vitro NDF degradability (NDFD) than untreated haylage. The use of fibrolytic enzymes applied to alfalfa haylage at ensiling increased the NDFD, despite minimal effects on the chemical composition of the herbage. However, the greater aerobic deterioration of fibrolytic enzyme-treated bales indicates higher dry matter losses during aerobic exposure. The use of FAEI with fibrolytic enzymes did not further enhance the effects of fibrolytic-enzyme treatments.

The aim of this study was to evaluate dry matter yield and nutritional value of palisade grass (Brachiaria brizantha cv. Marandu) using nitrogen doses and sprinkler irrigation in two periods of the year, aiming at reducing seasonality of forage production. It was used a randomized block design in a split-plot scheme, with five doses of nitrogen (0, 50, 100, 150, and 200 kg/ha/cut), and the sub-plots were defined by the seasons of the year (wet and dry season), with and without irrigation. During the wet season, in the plots with and without irrigation, doses of 175 and 161 kg/ha/cut promoted the highest dry matter yields. During the dry season, 171 kg ha-1N with irrigation resulted in the highest dry matter yield. During the same season, there was no response to N fertilization in the lack of irrigation. Average contents of CP were 10% with and without irrigation. Contents of neutral detergent fiber decreased with nitrogen doses, while acid detergent fiber was not affected by fertilization. Plots under irrigation reached the maximal acid detergent fiber content at N dose of 60 kg ha-1. Irrigation promotes increase of 15% increase in dry matter yield and it increases contents of neutral detergent fiber.
