  • The problems in the current domestic forage production were evaluated, and the prospective improvement was suggested in this paper. Grassland development in forest, production of high quality forages in upland and paddy land, efficient utilization of rice straw, development of new varieties of forages suitable for our environmental conditions and imported forages were described Among them, preferential production and utilization of forages using paddy field after rice harvest . should be enlarged for domestic supply of forages in Korea. Several studies were carried out to select the promising forage crops and barley cultivars for whole crop silage production, to determine productivity, nutritive value and production cost of forages produced in paddy field, and feeding effect of forages with Hanuwoo and milking cow for whole crop silage with forages produced in paddy field, 1999 to 2001, and also discussed restraint factors and activation plans for enlargement of forage production in paddy land. The promising forage crops in paddy field were rye and barley for Middle region, and rye, barley, early maturing Italian ryegrass and wheat for Southern region. The promising barley cultivars for whole crop silage in paddy field were Albori in Suwon, Keunalbori, Milyang 92, Saessalbori, and Naehanssalbori in Iksan, and Keunalbori, Albori, Naehanssalbori, and Saegangbori in Milyang, respectively. Silage production, quality and animal palatability of silage by trench and round bale were also compared. The production yields of whole crop barley silage(WBS) were 17,135kg as a fresh matter, and 6,011kg as a dry matter per ha, and the quality of WBS was 2∼3 grade, while that of rice straw silage was 4 grade as a farm basis. The production cost of WBS per kg was 83won as a fresh matter, and 238won as a dry matter. Feeding of WBS as forages on Hanwoo was very desirable for the improvement of live-weight gain, beef quality and farm income, particularly in growing stage of Hanwoo. Milk production and income were also increased, and feed cost was decreased by feeding of WBS. The daily voluntary intake of WBS in milking cow was 26.3kg as a fresh matter(DM 7.7kg) per head. Milk production when WBS was fed, was very similar to that of imported hay feeding such as Kentucky bluegrass or domestic corn silage. The issues to be solved in near future f3r stable forage production and supply in paddy land are sustainable livestock-forages policy, development & seed production of new varieties of barley, rye, Italian ryegrass and other promising forages, efficient demand & supply system of forages, solidification for mass production and utilization of forages, efficient application management of animal slurry on paddy field considering environmental agriculture/livestock industry, and break k development of bottleneck technique in production field. Domestic production & supply of high cost agricultural machine (round baler, wrapper, handler and so on), plastic wrapping film, and silage additives are also important.

  • Two experiments were carried out to investigate the effect of Murrah buffalo cows pulling sledges under field conditions on milk production and milk composition. In Exp. 1, 24 buffaloes in the fourth month of lactation were used. They were allotted to four treatments according to a $2{\times}2$ factorial arrangement: work or no work, and with or without urea-molasses cake supplementation (700 g/animal/day). Feeds consisted of 20 kg fresh elephant grass (18% DM), 2 kg rice bran per day and rice straw ad lib. The animals worked in pairs three hours per day (work done: $3464{\pm}786kJ/d$) five days a week for three months. Three teams worked in the morning and the others worked in the afternoon in the same day. The following day the working times were switched. In Exp. 2, 16 lactating Murrah buffalo cows in the sixth month of lactation were allotted to two groups (work and no work). They were fed with fresh ruzi grass (Brachiaria ruziziensis) ad lib. supplemented with 2 kg rice bran and 700 g urea-molasses cake. The working regime was similar to that of the first experiment (work done: $3753{\pm}879kJ/d$) and they worked for two months. In the first experiment, there was a small but significant drop (p<0.05) in milk yield from 3.5 to 3.0 kg/day due to work, but there was no supplementation effect. The working buffaloes lost 5.2 kg whereas the non-working animals gained 9.7 kg during the three months (p<0.05). Supplementation increased live weight by 9.9 kg as compared to -5.4 kg for those not supplemented (p<0.05). Milk composition was not affected by the treatments. In the second experiment, daily milk production was similar for both treatments and approximately 3 kg. No significant differences were found in milk composition or in live weight changes for working and non-working groups, respectively. It was concluded that work may cause a reduction in milk yield and a loss of live weight on a poor rice straw diet but that an appropriate supplementation can alleviate this situation.

  • Two male, rumen fistulated crossbred Brahman-Thai native beef cattle (body weight = $400{\pm}50$ kg), fed on rice straw as a source of roughage, were used as rumen fluid sources. The treatments were $2{\times}3$ factorial arrangements; two roughages (fresh cassava foliage and cassava hay) and three sulfur levels (elemental sulfur) at 0.2 (control), 0.5 and 1% of DM, respectively. The experiment revealed that the rates (c) of gas production, ammonia-nitrogen concentration, true digestibility, total concentration or molar proportions of VFA and microbial biomass were not significantly different between cassava hay and fresh cassava foliage. However, all parameters for cassava hay were higher than for fresh cassava foliage. The supplementation of 0.5% sulfur to fresh cassava foliage resulted in a significant increase in the rate of gas production, true digestibility, total concentration of VFA, microbial biomass, rate of HCN disappearance, thiocyanate appearance and cyanide percentage conversion into thiocyanate. However, there were no effects of sulfur supplementation at 0.2, 0.5 and 1% to cassava hay. The finding suggests the utilization of cassava foliage for rumen microorganisms in terms of fermentation and HCN detoxification could be improved by sulfur supplementation of 0.5% of DM.

  • 인삼의 주요 해충의 하나인 큰검정풍뎅이의 발생요인을 구명하여 효율적인 방제대책을 수립하기 위해 몇 가지 환경요인에 대한 산란선호성을 조사한 결과 큰검정풍뎅이는 지피식물이 없는 나지에는 전혀 산란하지 않았고 식물의 종류에 따라서도 차이를 보여 쑥. 망초, 바랭이, 쇠비름 등에는 잔디나 달맞이꽃에 비해 산란수가 많았으며, 토끼풀에는 산란하지 않았다. 지피식물이 바랭이일 때 지피도 높은곳, 토양경도가 낮은 곳에서 산란수가 많았다. 지피물이 볏짚인 곳은 산란수가 있어 나지와 유의차를 보이지 않아 볏짚은 산란유인으로 작용하지 않는 것으로 생각되며, 토양내의 부숙볏짚 역시 산란수에 영향을 미치지 않는 것으로 보였다. 또한 과건 또는 과습토양에서는 산란수가 현저히 감소하였다.

  • In search of a method to achieve sustainable agricultural practices, a trickling filter was employed for the piggery wastewater treatment, where rice straw was the support medium in place of more commonly used materials. The filtrate from the trickling filter were applied to a soil, on which orchard grass (Dactylic glomerata L.) was grown followed by amendment of the treated straw medium. Orchard grass was cut twice, and growth parameters and yields were measured. Soil chemical properties before and after harvesting orchard grass were analyzed. Development of the forage crop was greatly enhanced by the application of the filtrate in terms of fresh weight, dry weight, and the absorption of nutrients. Better growth and higher nutrient uptake were found in the second cutting of the orchard grass. Organic matter content, ionic intensity, exchangeable cations, and phosphate of the soil increased with the application of the filtrate. The relative high concentrations of salts in the piggery trickling filtrate, expressed in electrical conductivity and content of sodium, exerted no detrimental effect on the crop and soil.

  • The objective of the study was to evaluate the effects of Lactobacillus, cellulase, and molasses on chemical composition, fermentation qualities, and microorganism count of sugarcane bagasse silage after 30-days fermentation. The treatments were arranged according to a factorial arrangement (2 × 2 × 2) + 1, in a complete randomized design. The first factor consisted of two levels of Lactobacillus casei TH14 (TH14, 0 and 0.05 g/kg fresh matter; the second factor consisted of two levels of cellulase enzyme (C, 0 and 104 U/kg fresh matter); and the third factor consisted of two levels of molasses (M, 0 and 5 g/ 100 mL distilled water). A treatment (+1) referred to the use of rice straw without any treatments. The result showed that dry matter increased by 4% and neutral detergent fiber decreased by 2% of sugarcane bagasse when ensiled as a combination of additives as compared to untreated sugarcane bagasse. The pH and ammonia nitrogen were significantly dropped to 3.5 and 2.3 g/kg dry matter. Furthermore, lactic acid was increased by 64% when compared to untreated sugarcane bagasse, respectively. Lactic acid bacteria count was increased by 28% as compared to untreated sugarcane bagasse. Based on this experiment, fermenting with L. casei TH14, cellulase, and molasses in combination resulted in the promotion of the best qualities of sugarcane bagasse silage.

  • 수박재배에 적합한 양분함량보다 약 3배 이상 높고, 7년간 수박을 연작해온 시설 재배지에서 시비관리 및 생볏짚을 연용하면서 토양 중 염류경감 효과와 수박시들음증 발생률을 조사하였다. 시험은 관행구, 시비관리구, 시비관리 및 5, 10, 15 ton $ha^{-1}$ 생볏짚 처리구로 나누어 3년간 실시하였다. 유기물함량은 예상할 수 있는 바와 같이 대부분의 처리구에서 지속적으로 증가하였으며, 단지 시비관리구에서만 감소하였다. 토양 pH는 관행구 및 시비관리구에서는 변화가 거의 없었고, 시비관리-볏짚처리구에서 감소하는 경향을 보였다. 그러나 시험 3년차부터 10, 15 ton $ha^{-1}$ 시비관리-볏짚처리구에서 다시 증가하는 경향을 보였다. 치환성 양이온 즉 $Ca^{2+}$, $Mg^{2+}$, $K^+$, 중 $Ca^{2+}$$Mg^{2+}$의 함량과 수용성 음이온, ${NO_3}^-$, $Cl^-$, ${SO_4}^{2-}$, ${PO_4}^{3-}$의 함량은 시비관리구 및 시비관리-볏짚처리구에서 상당히 감소하는 경향을 보였다. 그러나 시비관리-볏짚처리구에서 생볏짚의 처리량과는 관계없이 시험 1년차에 많은 양이 감소한 후, 2~3년차에서는 더 이상 감소하지 않는 것으로 나타났다. 또한 치환성 $K^+$ 함량은 시비관리구에서 다고 감소하는 경향을 보였으나 다른 처리구에서는 시험기간 동한 거의 변화하지 않았다. 그리고 이러한 양이온과 음이온의 함량변화와 관계가 깊은 전기전도도(EC)를 조사한 결과 수용성 음이온 함량변화와 같은 경향을 보이며 감소하였다. 또한 수박생육과 관련하여 수박시들음증 발생률은 관행구에서 최고 약 20%까지 발생하였으나, 시비관리와 함께 생볏짚을 10 ton $ha^{-1}$ 이상 사용하면 최고3.5%까지 급격히 감소하였다.
