“…However, the difference in DM content in fresh forage due to cutting height difference before ensiling did not persist after ensiling ( Table 2 ). The CP, NDF, and ADF concentration of barley forage was different from the values reported by Yun et al (2009) with same barley hybrid, which might be due to different soil characteristics and harvesting stage of barley forage ( Ji et al, 2007 ; Song et al, 2011 ). The decreased NDF and ADF content of both forage and silage with increasing cutting height was in agreement with most other previous studies.…”

“…The increased DM content of fresh forages with the increase in cutting height in this study is related to the higher DM content of the upper part of WCB compared to the lower part. The grain and spike in the upper part in WCB contributed higher DM content ( Ji et al, 2007 ). Similarly, whole crop wheat (446 vs 477 g/kg) and corn (33.9% vs 41.5%) were also reported to have higher DM content with higher cutting height compared to the lower cutting height ( Neylon and Kung, 2003 ; Sinclair et al, 2003 ).…”

The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (Yuyeon hybrid) was harvested at height of 5, 10, and 15 cm from the ground level. Each cutting height was rolled to make round bale and ensiled for 100 days. After 100 days of ensiling, pH of silage was lower (p<0.05) in 5 cm, but no difference between 10 and 15 cm of cutting height. The content of lactate and lactate to acetate ratio were increased (p<0.05) in 5 cm of cutting height, whereas the acetate content was higher (p<0.05) in 10 and 15 cm than that of 5 cm cutting height. Aerobic stability was greater (p<0.05) in silages of 10 and 15 cm of cutting height. Three total mixed rations (TMR) were formulated with silages from the three different cutting heights (TMR5, TMR10, and TMR15) incorporated as forage at 70:30 ratio with concentrate (dry matter [DM] basis). In vitro dry matter digestibility was higher (p<0.05) in the TMR5 and TMR10 than that in TMR15, whereas in vitro neutral detergent fiber digestibility was higher (p<0.05) in the TMR10 and TMR15 than that in TMR5. Concentration of NH3-N was highest (p<0.05) in the TMR10 followed by TMR15 and TMR5. Total volatile fatty acid was decreased (p<0.05) with increased cutting height. The digestibility of DM and neutral detergent fiber were highest (p<0.05) in TMR15, than those in TMR5 and TMR10, whereas acid detergent fiber digestibility was higher (p<0.05) in TMR5 than that in TMR10. The results showed that increasing cutting height, at least up to 10 to 15 cm, of whole crop barley forage at harvest (Yuyeon) may be beneficial for making silage for TMR formulation and increasing digestibility of DM and NDF.

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.
