Objective: This study was conducted to confirm the effects of new inoculants producing-antifungal or esterase substances on rye silage and its rumen fermentation indices by comparing wild with mutated types.Methods: Rye harvested at dough stage was ensiled into 3 L mini bucket silo (1 kg) for 90 d in triplicate following: distilled water at 20 μL/g (CON); Lactobacillus brevis 100D8 (AT) and its inactivation of antifungal genes (AT-m) at 1.2×105 cfu/g, respectively; and Leuconostoc holzapfelii 5H4 (FD) and its inactivation of esterase genes (FD-est) at 1.0×105 cfu/g, respectively. After silo opened, silage was sub-sampled for the analysis of ensiling quality and its rumen fermentation indices.Results: Among the wild type inoculants (CON vs AT vs FD), FD inoculant had higher (p<0.05) in vitro digestibilities of dry matter and neutral detergent fiber, the total degradable fraction, and total volatile fatty acid in rumen, while AT inoculant had higher (p<0.05) lactate, acetate, and lactic acid bacteria in silage. Silage pH and the potentially degradable fraction in rumen increased (p<0.05) by inactivation of antifungal activity (AT vs AT-m), but lactate, acetate, and lactic acid bacteria of silage decreased (p<0.05). In silage, acetate increased (p<0.05) by inactivation of esterase activity (FD vs FD-est) with decreases (p<0.05) of pH, ammonia-N, lactate, and yeast. Moreover, inactivation of esterase activity clearly decreased (p<0.05) in vitro digestibilities of dry matter and neutral detergent fiber, the total degradable fraction, and total volatile fatty acid in the rumen.Conclusion: This study concluded that FD inoculant confirmed esterase activity on rye silage harvested at dough stage, while AT inoculant could not be confirmed with antifungal activity due to the absence of mold in all silages.

“…The chemical composition of rye forage in the present study had higher SC such as NDF, ADF, and HEMI concentrations than rye forage harvested at the heading stage (74.4% vs 60.2%, 46.2% vs 35.9%, and 28.2% vs 24.3%, respectively) [22]. This might be due to the different maturity stage, which was harvested at dough stage in the present study.…”

“…Among forage crops ensiled in Japan and other countries, the barley crop (Hordeum vulgare L.) has low buffering capacity, a high proportion of fermentable carbohydrates and is relatively easy to ensile (Acosta et al 1991). However, inoculants based on wilting and lactic acid producing bacteria (LAB) at the time of ensiling improve the silage fermentation (Kim et al 2001;Hristov and McAllister 2002) and digestibility of whole crop barley silage, its nutrient intake and animal performance (McAllister et al 1995). Therefore, the effect of adding AAFB at the time of ensiling whole crop barley should be understood in detail.…”

Effects of phenylalanine fermentation byproduct and sugarcane molasses on fermentation quality and rumen degradation of whole crop barley (Hordeum vulgare L.) silage in situ

Phenylalanine fermentation byproduct (PFB) is generated by purifying phenylalanine products from microbial fermentation in the food industry. We examined the function of PFB as an ensiling agent to improve the silage fermentation and nutritive value of forage crops. We investigated the fermentation quality and rumen degradability of whole crop barley (Hordeum vulgare L.) silage in situ. We ensiled this type of silage in a laboratory scale using five compositional ratios (v/v) of PFB (20%, 40%, 50%, 60% and 80%) and a mixture of sugarcane molasses (SCM). Controls included the same volumes of water as the mixture of sugarcane molasses. The following strains Lactococcus lactis ssp. lactis (IFO12007), Leuconostoc mesenteroides ssp. mesenteroides (IFO12060), Lactobaccillus plantarum (IF014713), Pedioccocus acidilactici (IFO3858), Clostridium butyricum (IFO3858) and silage yeast (strain MY; separated from whole crop rice silage in this laboratory) were cultivated at 30°C in the recommended media containing a substituted carbon source depending on the compositional ratios of PFB and SCM mixtures. The growth of these strains was determined by measuring the optical density at 600 nm (OD600). The growth of the lactic acid bacteria significantly (P < 0.001) increased in the presence of all PFB additives as compared with the control. The growth of C. butyricum was significantly increased, whereas that of silage yeast was decreased under all conditions. The concentrations of lactate and total organic acids were significantly higher (P < 0.001) whereas those of acetate were lower in all PFB silages. These results indicated that PFB improved the silage fermentation of forage crops. With leaf and stem fractions, the neutral detergent fiber (NDF) content was significantly (P < 0.001) decreased by the PFB additive and the rumen degradability of DM and NDF in situ was also significantly increased (P < 0.01 and P < 0.001, respectively).

We examined the use of basic forage data and indicators of forage productivity in different regions of Korea. The productivity of winter forage crops was evaluated from mid to late May 2012 by directly collecting information from farmhouses. A survey of winter forage crop productivity was conducted with 66 farmers in 16 regions; including, Italian ryegrass (IRG) from 22 farmers in 11 regions, whole crop barley from 21 farmers in eight regions, rye from 11 farmers in five regions, and IRG mixed with whole crop barley from 12 farmers in six regions. The results indicated that the Konju region exhibited higher yields of dry matter (DM) forage (15,128 kg/ha) and that the Dangjin region (reclaimed land) showed the lowest (3,885 kg/ha). The average yield of DM forage was 9,418 kg/ha. Yields of whole crop barley and IRG mixed with whole crop barley were comparatively higher than those of rye and IRG. We conclude that overall forage productivity was influenced by farmer's cultivation ability rather than the forage cultivation environment.
