  • 본 연구는 오디수확 후 버려지는 뽕잎을 이용하여 누에를 사육할 경우 추가 소득을 올릴 수 있다는 점을 고려하여 시설하우스 내 오디용 뽕나무 유인방법별 오디수확 후 뽕잎생산량과 적정누에 사육량을 구명하기 위하여 수행하였다. 먼저 오디용 뽕나무 수형별 뽕잎생산량을 조사한 결과, 뽕나무 1주당 관행은 4.75 kg 생산되는데 비해 T자형은 7.07 kg, Y자형은 6.55 kg으로 각각 49%와 38% 더 생산되었다. 그리고 오디용 뽕나무 시설재배에서 생산되는 뽕잎으로 누에 1상자를 사육할 때 소요되는 뽕잎량은 평균 302 kg으로 분석되었다. 한편 대부분 농가에서 선호하는 5령 3일 누에를 기준으로 오디용 뽕나무 시설재배 수형별 누에사육량을 분석한 결과, 10 a당 생산되는 뽕잎으로 관행 3.24 상자인 반면, T자형 4.17상자, Y자형은 3.83 상자였으며, 평균 3.74 상자 사육 가능한 것으로 분석되었다.

  • Two experiments were conducted to evaluate the nutritional value of common fodder tree leaves with goats fed at 50% of total ration. In experiment 1, leaves from six fodder tree species i.e., Ailanthus aitissima, Elaeagnus angustifolic, Morus alba (Mulberry), Populus spp, Robina pseudoacacia and Salix babylonia were harvested in spring and winter from northern areas of Pakistan. Chemical composition and apparent in situ dry matter digestibility (DMD) of fodder tree leaves were measured. Results showed that crude protein (CP) values were higher (p<0.05) in all the species during spring compared to winter (17.9% vs 12.0%). The concentration of NDF in Elaeagnus and Robinia was higher in spring, whereas no seasonal difference was found in other species. In situ DMD was higher (p<0.05) in Ailanthus and Populus at spring while it was higher (p<0.05) in Elaeagnus, Mulberry and Robinia at winter. There was no (p<0.05) seasonal effect on in situ DMD of Salix. In experiment II, four iso-nitrogenous and iso-caloric rations viz., A, B, C and D were prepared containing 50% (winter harvested) sun dried leaves of Salix, Robinia, Mulberry and Elaeagnus, respectively and 50% concentrate. Dry matter and crude protein intakes were higher (p<0.05) given ration A (Salix) whereas DM and CP digestibility was lowest (p<0.05) given ration B. Nitrogen retention was higher (p<0.05) given ration A. Goats fed on fodder tree leaves and concentrate showed moderate intake and digestibility.

  • Vermicompost, manure, compost and organic fertilization are ecofriendly. Nowadays, many products resulted from sericulture consumed by humans such as mulberry leaves, fruits, mulberry tea, silk and natural silk cosmetics. Soil applications of three treatments with vermicompost (0.5, 1 and 2 tons per 0.42 hectare) and recommended rate of mineral fertilizers of nitrogen phosphorus potassium were used for investigation. Impact of fertilization on mulberry plant traits of moisture, number of shoots/tree, total shoots length/tree, number of leaves/shoot, number of leaves/ (100g), leaf yield/tree and leaf yield of fadden/season were recorded. In addition the effect of fertilization on larval and cocoon characters of young instar duration, fifth instar duration, total larval duration, larval mortality percentage, weight of third instar larvae, weight of fourth instar larvae, weight of fifth instar larvae, fresh cocoon weight, fresh shell weight, pupae weight, cocoon shell ratio, silk productivity, cocooning percentage, pupation ratio, number of cocoons/ liter, crop cocoons by number, crop cocoons by weight, fecundity and fertility. Using vermicompost treatment was enhancing plant characters. Treatments of V3, V2 and V1 were shortage young, fifth and larvae durations. Mostly feeding silkworm during the whole larval duration on treated mulberry leaves with vermicompost improving the traits average. Using vermicompost for fertilization by rate of V3 and V2 is better than others for cocoon characters for females and males.V3 and V2 of vermicompost per 0.42 hectare is recommended for rearing mulberry silkworm instead of mineral fertilization.

  • In order to develop new functional yogurts using mulberries and mulberry leaves, which were cultivated in Hwasun-gun, Jeonnam Province, Korea, the nutritional compositions, fermentation conditions, sensory properties, and storage stabilities of the yogurts were analyzed. The mulberry powder yogurt contained 87.96% moisture, 3.21% carbohydrate, 4.52% protein, 3.63% lipid, and 0.68% ash, and the mulberry leaf yogurt contained 86.36% moisture, 4.13% carbohydrate, 4.87% protein, 3.79% lipid, and 0.85% ash. A yogurt base was fermented for 13 h with 0.01% ABT-5 starter inoculum at $40^{\circ}C$. To prepare the mulberry jam and mulberry leaf yogurts, a variety of mulberry jam and mulberry leaf samples were added to the yogurt base. The sensory evaluation results of the yogurts containing the mulberry jam and mulberry leaves indicated that a product made with 15% mulberry jam was more strongly preferred than other samples. When the mulberry jam and mulberry leaf yogurts were stored at $4^{\circ}C$ for 15 d, there were no significant changes in pH, titratable acidity, or viable cell numbers of lactic acid bacteria and Bifidobacterium bifidum.

  • Entomopathogenic nematodes, Heterorhabditidae and Steinernematidae, were isolated from the soil of mulberry field, and the high infectivity and invesiveness were confirmed in the silkworm, Bombyx mori. The cause of non-microbial and acute flacherie was found as an disease by infection with soil-born nematodes through the mulberry leaves contaminated with soil and rainwater. The causal nematodes were isolated by silkworm trap from all of the 5 soil samples collected on the 5 mulberry fields, and identified as 3 strains of Heterorhabditis sp. and 2 of Steinernema sp. Rainwater itself, however, wasn't engaged in the silkworm disease, mulberry leaves with rainwater was rather profitable for cocoon production when the leaf quality was too hard to feed silkworm. Feeding of wet mulberry leaves with rain might not so harm to silkworm when the condition of rearing room to be kept at suitable temperature and ventilated well. Nematode infection of silkworm could be occurred by harvesting and feeding of contaminated mulberry leaves on the weather condition of rainy and wind. For the prevention of nematode infection, silkworms should be fed the leaves harvested from the higher portion of the mulberry tree in rainy days. For an oppositional application of this susceptibility of silkworms to nematode, might be useful on the collection and amplification of nematode agents for biotic control of pest insects.

  • One of the main processes of tenderizing beef in Joseon Dynasty was chemical methods involving Apricot seeds, manchu cherry twig and leaves, bamboo skins, mulberry tree bark, mangsa (硭砂), salmiacum (磠砂), alcohol, fermented malt, and original honey. This study analyzed and compared the effect of broussonetia papyrifera, fermented malt, cherry trees, and mulberry tree bark from old cookbooks. Tenderizing beef with cherry trees was most effective in the experiment on shearing force, TPA, and electrophoresis of beef. According to sensory evaluation and electrophoresis test results, tenderized beef with mulberry tree bark was slightly more preferred over the method using cherry trees. However, in accordance with the above mentioned experiment, quantitative descriptive analysis showed that the most common tenderizing material was derived from morus alba powder.

  • 춘하추 삼기사육에 있어서 연구조사한 결과 본시험에서 다음과 같은 결과를 얻었다. 1. Menthol의 상기첨식시험에서 Menthol의 1%내에서는 잠아의 생리에 하등의 영향이 없다는 결과를 얻었다. 이 결과는 누에의 상기한 실용형질 전면에 걸쳐 무해이며 또 유익하다는 점도 발견치 못하였다. 2. 박하를 상전에 간작하여 지장이 없음이 연명되였으며 박하엽에 거찰된 상엽을 잠아에 결여하여도 누에 생리에 하등영향이 없다. 3. 들깨(荏)에 있어서도 2항과 동일하다. 4. 결과적으로 박하의 상전간작은 무해로운 작물로 사료되며 들깨의 상전간작도 농민들이 기피하는 경향이 있으나 잠아에는 하등영향이 없다.
