“…In this experiment, the highest lactic acid concentration was detected on May 9 (heading). This result differs from the conclusion reported by Kim et al [22] that the lactic acid content of whole crop barley silage ensiled at the milking stage showed the highest value, perhaps due to the forage species and A C C E T E D different experimental location. Another reason for the high lactic acid content in the May 9 harvest is the WSC content.…”

Limited data about the effects of various factors on forage quality and β-carotene content of rye produced in Korea are available, so this study investigated the effects of two preservation methods. Samples were collected from rye harvested every 5 days between April 25 and May 31, and comparisons were done among rye silage wilted for different periods of time and hay of three growth stages of rye. For the silage, dry matter (DM), acid detergent fiber (ADF), and neutral detergent fiber (NDF) contents increased with advanced maturity of rye, whereas crude protein, in vitro dry matter digestibility (IVDMD), total digestible nutrients (TDN), relative feed value (RFV), and DM loss decreased ( p < 0.0001). Wilting increased the DM content and pH value significantly ( p < 0.0001). Silage harvested at the heading stage had the lowest pH value (4.45), propionic acid (0.83 g/kg DM), butyric acid (0 g/kg DM), and fungi and yeast populations (3.70 Log CFU/g of fresh matter [FM]); conversely, it had the highest lactic acid (9.7 g/kg DM), lactic acid bacteria (LAB) (6.87 Log CFU/g of FM), total microorganisms (TM) (7.33 Log CFU/g of FM), and Flieg’s score (70) ( p < 0.0001). Wilting elevated LAB and TM populations, but it had no consistent effect on other fermentation products. Both delayed harvest and prolonged wilting decreased β-carotene content. Rye silage harvested around May 9 (heading stage) with 24 h of wilting was preferred for highland, Pyeongchang. For rye hay, advanced maturity decreased DM loss, IVDMD, TDN, and RFV, but it increased DM, ADF, and NDF significantly ( p < 0.05). β-carotene was decreased by delay of hay-making. Consequently, to attain lower DM loss and higher hay quality, the harvest date of May 9 (heading stage) is recommended.

This study was carried out to investigate the growth characteristics, yield, chemical compositions and nutritive yield of whole crop barley varieties harvested in a paddy field. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of five whole crop barley varieties (Yuyeon, Youngyang, Wooho, Dami, Soman). The planting date was on 21 October 2009 and the samples were harvested on 21 May 2010. Dry matter yield was higher in Youngyang and Dami than other varieties (p<0.05). Crude protein, crude fat, crude ash, ADF and TDN were not significantly different. Crude fiber was the highest at Dami (31.4%), and Youngyang (31.4%) exhibited the lowest crude fiber compared to other varieties (p<0.05). NDF was higher in the order of Wooho > Dami > Soman > Yuyeon > Youngyang (p<0.05). Total mineral content was higher in the order of Youngyang > Wooho > Dami > Soman > Yuyeon (p<0.05). The contents of both essential and non-essential amino acids were not different among whole crop barley varieties. Yields of crude protein was the highest in Wooho (p<0.05), and yields of mineral, amino acid, free sugar and TDN were the highest in Youngyang. Based on the results from this study, it can be suggested that Youngyang and Wooho showed to have higher productivity and high nutritive values compared to other varieties.

The present study was conducted to evaluate the productivity of Sorghum × sudangrass (SX17) hybrid and BMR (brown mid rib) Sorghum×sudangrass hybrid and silage quality of these forages with corn grain supplementation. The effect of corn grain supplementation on the quality of silages was also investigated. No remarkable differences at growth characteristics and productivities in two hybrids were found. Sugar content, however, in stem of BMR hybrid showed significantly great (p<0.05) and the difference between two hybrids was about 2 B°. Ratio of lactic acid in total organic acid in BMR hybrid (82.8%) was significantly greater than the control (SX17 hybrid) (78.5%) (p<0.05). Ratio of butyric acid in total organic acid in SX17 hybrid (18.5%) was significantly greater than BMR hybrid (9.8%) (p<0.05). According to the result of organic acid ratio, it could be assumed that the use of BMR hybrid can improve silage quality. NDF and ADF contents in both SX17 and BMR hybrids were significantly declined with increased corn grain supplementation (p<0.05). Different TDN values in SX17 (56.2) and BMR (57.1) hybrids were detected. However, TDN values of both SX17 and BMR hybrid silages were significantly elevated by increasing the proportion of ground corn (p<0.05).
