The object of this experiment was to evaluate nutritive value of roughage which was collected by Woosung Feed Co., Ltd. in Korea in 1999-2000. Nineteen kinds of roughage(l32 samples) were collected by Woosung Feed Co., Ltd. and their chemical composition, ADF, NDF, Ca and P. were analysed. In addition, their DMD, DMI, WV and hay grades were calculated based on analysed values. The CP content of roughage was ranged from 17.35%(alfalfa hay) to 4.00%(Italian ryegrass hay), and ten kinds of roughage under six percentages were observed. The NDF content of roughage was ranged from 47.50%(sugarcane leaf) to 78.84%(orchardgrass hay), and eight kinds of roughage above seventy percentages were observed. The DMD of roughage was ranged from 66.38%(beet pulp) to 50.95%(orchardgrass hay). The WV of roughage was ranged from 60.1 l(orchardgrass hay) to 125.07(sugarcane leaf). In hay grade of roughage, the first grade was assigned to sugarcane leaf only and the third grade and fourth grade were assigned to four kinds of roughage each. Bermudagrass straw received the fifth grade, and the nine kinds of roughage received the poor grades. As shown in the above results, nineteen kinds of roughage were mostly low in crude protein contents and dry matter digestibility, but they were high in fibrous contents. Futhermore, while only one kind of roughage was evaluated as obtaining the first grade, nine kinds of roughage were evaluated as the poor grade. Hence, we know that roughage which was collected in Korea was mostly low in their quality and that there was significant difference in their feed value among those roughage(P<0.05). Therefore, it is necessary to mark the hay quality for purpose of distributive circulation of roughage. (Key words : Roughages, Nutritive value, DMD. RFV. Hay grade)

The objective of this experiment was to evaluate chemical composition, dry matter(DM) digestibility, DM intake, relative feed value(RFV) and hay grade of imported roughage which was collected by wholesale dealer at Chungnam province in 1999. Experimental roughages includes 8 kinds of imported hays(com stover bale, tall fescue straw, green cell, bermudagrass straw, reed camarygrass straw, alfalfa bale, sugarcane bale and oat hay) and mixture hay(contro1) which was harvested at Chungnam National University experimental field. Compared with mixture hay(contro1) except for alfalfa bale, crude protein of most imported roughage was low, but NDF, ADF, cellulose and lignin compound were high. Futhermore, DM digestibility, DM intake, RFV and hay grade of imported roughage except for alfalfa bale was significantly lower than those of mixture hay(control)(P<0.05). Therefore, it is necessary to evaluate the economic value in the aspect of quality for the imported roughages. (Key words : Imported roughage, RFV, Hay grade, Nutritive value)

An experiment was carried out to determine the effect of cultivar and tedding frequency on changes of moisture content of oat(Avena sativa L.) hay during field drying and on quality of baled oat hay after storage. The experimental design was a split-plot with the four oat cultivm such as 'Magnum', 'Cayuse', 'West' and 'Murray' as main plots and the two tedding frequencies such as 1 or 3 times a day as subplots in three replications. Moisture content of fresh cut oat cultivar was higher in the order of 'Magnum', 'Cayuse', 'West', and 'Murray' and the moisture content difference among the cultivm was maintained to the final curing day(P< 0.05). Moisture loss from the oat hay during the last 3 curing days was greater with 3 tedding a day than I tedding a day. Temperature of baled oat hay began to rise critically from the 6th day of storage and wa5 highest in 'Magnum' oat cultivar($45.3^{\circ}C$). Total nitrogen and ADIN contents of late maturing oat hay 'Magnum' and 'Cayuse' were higher than those of early maturing 'Murray' and 'West'. Tedding frequency did not influence total nitrogen and ADIN contents. ADF and NDF contents of early maturing oat hay were higher than those of late maturing oat hay. Relative feed value (RFV) of 'Magnum' oat hay was the highest(l06) and classified as Grade 2 in forage quality standard. Quality grade difference between early and late maturing oat cultivan was only 1 or 2.

본 연구는 수입건초의 품질평가를 통해 사료가치를 평가하고 초종 및 등급별 현황을 파악하고자 수행되었다. 수입건초의 품질 평가를 위하여 2016년부터 2018년까지 전국 건초 수입상, TMR 회사와 축산 농가에서 목건초 9종 133점을 수집하였다. 수입건초의 품질등급이 3~4등급 수준으로 대부분의 수입건초가 사료성분이 낮은 것으로 판단된다. 알팔파의 품질등급별 사료성분은 ADF, Ash, TDN 및 DDM에서 유의적인 차이가 나타났다(p<0.05). 알팔파에 표기된 품질등급이 사료성분을 통해서 산출된 실제 품질 등급과 유사하지 않았다. 화본과목초의 품질등급별 사료성분은 DM 및 CP를 제외한 모든 항목에서 유의적인 차이가 나타났다(p<0.05). 국내에 유통되는 화본과목초 중에서 저품질인 품질등급 미표기가 49%를 차지하고 있으므로 사료성분에 따른 품질기준 제시가 시급하다. 이상으로 수입건초의 사료성분을 검토하였을 때 표시된 품질등급보다 낮은 결과를 나타내었다. 이는 수입건초에 표시된 품질등급만으로 판매가격을 책정하는 것은 축산 농가 및 사료제조사 등에 경제적 손실을 야기한다고 볼 수 있다. 수입건초의 품질등급을 재 검토하는 제도적 장치가 마련되어야 한다.

An experiment was carried out to determine effect of cultivar, drying agent concentration and preservative on the moisture content, temperature and quality changes of fall harvested oat(Avena sativa L.) hay during field curing and storage. The main plots consisted of the cultivar such as 'Foothill' and 'Swan', the subplots consisted of drying agent concentration such as 7Skg/ha(C1), lOSkglha(C2) and control(C0) and the sub-subplots consisted of preservative such as buffered acid(BA), lactic bacteria inoculant(LB) and control(C0). Moisture contents of 'Foothill' and 'Swan' oat cultivar at harvest were 635.5 and 385.4%DW(Dry weight), respectively, but the final moisture contents of the oat cultivars were 117 and 86%DW. The moisture content of cut oat was not affeded by drying agent concentration. Core temperature of baled 'Swan' oat hay was a little higher than that of 'Foothill' and no consistent preservative effect was found. Total nitrogen content of 'Swan' oat hay was 3.08% and that of 'Foothill' oat hay was 3.45%(P<0.05). Drying agent treatment increased total nitrogen content of 'Swan'(P <0.05), but preservative had no effect. Crude fiber content of oat cultivar was increased as the curing progressed(P<0.05) and the difference of crude fiber content of oat cultivar was maintained through the whole curing period. Effect of drying agent concentration on crude fiber content was not found after preservation. Crude fiber content of 'Swan' oat hay was higher than that of 'Foothill' by 1.O% in ADF and 3.1 % in NDF(P<0.05). No preservative effect was found in crude fiber content. According to RFV of oat cultivar at harvest, forage quality of 'Foothill' and 'Swan' was Prime and Grade 1, respectively, but that of both cultivm was above Grade 2 at the final curing day. RFV of the stored 'Foothill' and 'Swan' oat hay was 122 and 114(P<0.05), respectively, and the quality of oat hay was classified as Grade 1 and 2, respectively, according to the forage quality standard assigned by AFGC.

An experiment was camed out in 1994 to determine the effects of curing periods and preservatives on the characteristics and forage quality of baled alfalfa(Medicago sativa L.) hay after 60 days of storage. The main plots consisted of the curing periods such as 5 and 7 days, and the subplots consisted of preservatives such as commercial propionic acid preservative, lactic inoculant and control. Temperature during storage remained lower in 7 days cured hay bale than in 5 days and didn't rise over $30^{\circle}C$ in 7 days cured hay bale. After storage, bale with 7 days curing remained in better condition by visual assessment and DM loss of the bale was 21.4% with 5 days curing and 11.8% with 7 days curing. ADF and NDF contents of 5 days cured baled hay were 43.0 and 56.1%. respectively, which were lower than those of 7 days cured baled hay by 1.3 and 1.4%, respectively(P< 0.05). ADF and NDF contents of preservative treated baled hay were higher than those of the control(P<0.05). According to RFV, forage quality of the control and inoculant treated baled hay of 5 days curing, and the control of 7 days curing was classified as 3rd grade, but other baled hay was classified as 4th grade. The total nitrogen content of 5 days cured baled hay was 1.84% and 7 days was 1.38%(P<0.05). Significant differences(P<0.05) in total N content of baled alfalfa hay were found among the preservatives. ADIN/total N of 5 and 7 days cured baled alfalfa hays was 28 and 26%. respectively.

Background: This study was aim to observe the effects of feeding mixed local hay (MH) consisted of 55% orchard grass (Dactylis glomerata L.), 35% tall fescue (Festuca arundinacea) and 10% red clover (Trifolium pratense) to Hanwoo steers on performance, carcass characteristics and meat quality (longissimus thoracis) compared with feeding imported timothy hay (TH) and local rice straw (RS). Results: Although no significant effects were found on animal performance and carcass yield grade, the carcasses of MH group had higher marbling score and quality grade than those of RS and TH group (P < 0.05). Therefore, higher fat content (P < 0.001), lower shear force and hardness value in the beef of MH group than that of other groups were observed. Furthermore, the beef of MH group had higher CIE $a^*$ value (redness) than that of other groups and feeding MH to Hanwoo steers lowered n-6 to n-3 fatty acids ratio in beef. Conclusions: Mixed hay provided benefits on meat quality and could be used for Hanwoo fattening program.
