This study was carried out to investigate the effect of replacing dried mugwort (Artemisia montana Pampan) in concentrate a time of preparation pellet. The treatments, arranged in a 4${\times}$4 Latin square design, were four additional levels of mugwort at 0, 3, 5 and 10% in concentrate. Four crossbred (CorriedalexPolwarth, t) sheep with a mean body weight of 41.3 kg were used to evaluate nutrients digestibility, palatability, fermentation characteristics and microbial protein synthesis in the rumen. The digestibility of crude protein was improved (p < 0.05) to 6.1 % - 8.6 % in sheep fed 3, 5 and 10% mugwort pellet treatments compared with that of control. That of crude fat and NDF was improved (p < 0.05) to 5.8 % - 7.3 % in sheep fed 3 % compared to other treatments. The ruminal pH was significantly (p < 0.05) decreased in sheep fed 3 % mugwort pellet compared to other treatments when observed at 0.5 hour after feeding. The ammonia nitrogen concentrations were the highest in sheep fed all treatments at 1 hour after feeding. The ruminal concentrations of acetic acid and propionic acids were an improvement (p < 0.05) at the 3% and 5% treatments. Retained nitrogen of 3, 5 and 10% treatment with the value of 2.24 - 2.82 g was higher (p < 0.05) than that of the control with 0.78 g and microbial protein production of 10% treatment was higher (p < 0.05) than that of control. This study suggested that the replacing with 3% dry mugwort (Artemisia montana Pampan) in concentrate a time of preparation pellet will improve nutrient digestibility, palatability, ruminal fermentation characteristics and feed value.

This study was conducted to examine the nutrient digestibility and ruminal fermentation characteristics in sheep fed dried mugwort and mugwort silage for 5% levels of rice straw in the basal diet, and mugwort pellet for 5% levels of concentrate in the basal diet. For the experiment, they were given a basal diet containing of rice straw and concentrate mixed at a 3: 7 ratio (DM basis). The treatments were designed as a 4 ${\times}$ 4 Latin square design with four sheep (50.2 kg body weight). The digestibility of crude protein was increased (p < 0.05) to 4.6 - 6.2 % in sheep fed mugwort silage treatments (60.23 %) compared with those of control (54.08 %) and dried mugwort treatment (55.67 %). That of ether extract was iicreased (p < 0.05) to 4.8 - 8.8 % in sheep fed mugwort silage treatments (80.22 %) compared with those of control (71.47 %) and dried mugwort treatment (75.46 %). In the dry matter intake, mugwort silage treatment (904.44 g) was the hightest and mugwort pellet treatment, dried mugwort treatment and control were 810.66 g, 780.66 g and 742.18 g, respectively. The ruminal pH in all treatments were rapidly decreased (p < 0.05) at 0.5 and 1 hour after feeding and slowly increased at 2, 4 and 8 hours after feeding, especially mugwort silage treatment. The ammonia nitrogen concentrations were the highest (p < 0.05) in sheep fed mugwort silage treatment (11.24 - 12.05mg / 100 rnz) at 0.5 and 2 hours after feeding. The ruminal concentrations of acetic acid (6.06 mmol /100 $m\ell$) and propionic acid (2.35 mmol/ 100 mz) were an increased (p < 0.05) at the mugwort silage treatments at 1 and 2 hours after feeding. Purine derivatives out put (13.41 mmol / d) and microbial protein production (11.61 mmol / d) were increased (p < 0.05) compared with those of control (5.42 and 4.93 mmol / d).

본 연구는 쑥 펠렛 사료 급여에 따른 돼지의 성장율과 육질에 미치는 영향을 구명하고자 거세돈과 비거세돈에게 각각 대조구, 쑥 펠렛 3％, 쑥 펠렛 5％씩을 첨가급여하여 60일간 사양한 후 실험한 결과는 다음과 같다. 일당증체량에서 거세돈구 및 비거세돈구의 쑥 펠렛 사료 급여구가 대조구보다 유의적으로 높았다(p<0.05). 사료요구 율은 거세돈구가 비거세돈구보다 낮았고, 거세돈구의 경우는 쑥 펠렛 첨가에 따라 낮아지는 경향을 보였다. 전처리구간의 돈육의 일반성분은 조지방 함량을 제외하고 처리구간에 차이가 없었고, 그 중 거세돈구는 쑥 펠렛 급여에 따라 조지방 함량이 낮아져 유의성이 인정되었다(p<0.05). 전단력과 관능검사는 거세돈구가 비거세돈구보다 높아 유의차가 있었고(p<0.05), 또한 쑥 펠렛 급여구는 대조구보다 크게 향상되었다(p<0.05). 거세돈구의 경우 연도와 향미는 쑥 펠렛 3.0％ 급여구가 가장 좋게 나타났다. 돈육의 카뎁킨 함량은 거세돈구가 비거세돈구보다 더 높은 경향이었고, 쑥 펠렛 첨가 수준이 증가함에 따라 높아지는 경향을 나타내었다.

This study investigated the effect of coated feed using mixed oil on rumen fermentation characteristics. Two experiments were conducted based on materials that were mixed. First, cashew nut and soybean oils were mixed with white mineral oil. And second, different plant extracts were mixed with white mineral oil. At first experiment, inclusion levels of mixed oil on diet (0.03%, 0.1%, 0.5%) were applied as variables. A coated diet was fermented with rumen inoculum according to in vitro rumen fermentation and its parameters were investigated. In the result of first experiment, no negative effects on rumen pH were found. Significantly decreased dry matter digestibility was detected at 0.5% treatment (P<0.05). Total gas productions in control and 0.03% were significantly greater than those of others (P<0.05). Significantly reduced methane productions were found in all treatments compared to the control (P<0.05). Inclusion of mixed oil did not affect on ammonia production. Total volatile fatty acid production was also not influenced by coating with mixed oils. Rumen fermentation parameters were greatly changed according to introduced plant extracts at second experiment. The significantly lowest and greatest ammonia productions were found at treatments with Ixeris dentata and Plantago asiatica, respectively (P<0.05). The significantly greatest acetate and propionate productions were detected at treatments with Crucuma longa and Zizyphus vulgaris 1, respectively (P<0.05). All treatments, except Chrysanthemum idicum, Euyale ferox seed, Moringa leaf and fruit and Zizyphus vulgaris 1, showed significantly increased total volatile fatty acid production compared to the control (P<0.05). Only Paeonia lactiflora showed significantly lesser gas production than the control (P<0.05). In methane production, Ceramium, Zizyphus, Paeonia, Agrimonia, Torilis, Mugwort, Foeniculum, Euphorbia, Taraxacum, Artemisia, Momordica, Curcuma and Moringa reduced methane significantly compared to the control (P<0.05).
