“…Growing winter annual forage crops on rice fields during winter ‐ spring season has been promoted to reduce rice stockpile and produce necessary winter forage in South Korea. Whole ‐ crop barley ( Hordeum vulgare L.) produces high‐quality forage for ruminant animals when harvested at immature stages (Kim et al, ; Marinaccio, Reyneri, & Blandino, ; Seo, ). In South Korea, whole‐crop barley is considered one of the most important domestic winter crops taking about 10% of the total forage crop land (Seo, ).…”

Rice production has surpassed market demand in South Korea, and it is necessary to diversify the inputs of available agricultural resources from rice production to forage or other more demanded grains. This research was conducted to develop a yield predictive model of whole‐crop barley (Hordeum vulgare L.) based on climatic data in South Korea. A data set (n = 290) containing dry matter yield (DMY), cultivated locations and climatic variables was developed based on collected research reports. With DMY as the response variable, three optimal climatic variables including spring accumulated temperature (SAT), period to accumulated temperature 150°C (PAT150) and spring duration of sunshine (SDS) were selected through the stepwise approach of multiple regression analysis. Subsequently, through the general linear model, the yield predictive model including the three climatic variables and cultivated locations was constructed. The adjusted R2 of the model was 51.6%. Meanwhile, the model was tested through residual diagnostics and cross‐validation. The selection of SAT, PAT150 and SDS confirmed that the growth and development of autumn‐seeded whole‐crop barley were active in the next spring in South Korea, while the coefficient of determination of the model was lower than anticipated since only considering climatic variables. In the future research, a new model with higher interpretability might be developed via increasing data size, adopting more environmental variables or constructing the models for each location individually instead of pooling their data together.

This study was conducted to determine the effect of dietary whole-crop barley silage on the daily feed intake, daily weight gain, velvet antler yield and economic efficacy in elk during growth. A total of 21 elk (average BW 303 kg, 5 years old) were allotted randomly to three treatments. The three treatments were T1 (hay diet), T2 (whole-crop barley silage), and T3 (50% hay + 50% whole-crop barley silage). The average daily weight gain of T3 was higher than the others throughout the entire experimental period. The average daily feed intake of elk in decreasing order was as follows; T1>T3>T2. The velvet antler yield was higher in T3 group (8,585 g) compared with T1 (8,037 g) and T2 (7,713 g). However, there were no significant differences in the average daily feed intake, average daily weight gain, or velvet antler yield (p>0.05). In economic efficacy, T3 was gained about 29~43% more value than T1 or T2. In conclusion, the mixed feeding of 50% hay and 50% whole-crop barley silage was more effective than feeding hay of barley alone, in terms of average daily weight gain, velvet antler yield, and economic efficacy in elk.
