Crude fiber, ash and crude fat in various parts of root had highly significant correlation each other. In shoot, crude fiber showed highly significant negative correlation with crude fat or crude protein which were in highly significant positive correlation each other. In whole plant, crude fiber and ash, crude fat and crude protein, Mn and Cu, ash and Ca, and ash and B showed positive correlation respectively and negative between crude protein and crude fiber. Ash, crude fat and curde fiber showed highly significant positive correlation with all mineral nutrients in root while in shoot pairs haying significant correlation were less and most of these were in negative correlation. Ash with Mg, K or Cu, crude fat with B, crude fiber with Cu, K, Mg in root and crude fat with Mn in shoot were specially high significant pairs. Ash with B and crude fat with Mn were significant in root, shoot and whole plant. Saponin contents in root showed highly significant positive correlation with crude fiber, crude fat, ash and with all other mineral nutrients except N, P, Mg while, in shoot, it showed, negative correlation with K and crude fiber, ana positive with N, Mn, Cu, and crude fat. Saponin showed positive correlation with crude fat, Mn, Cu, in root, shoot and whole plant.

The present study aimed to examine the effect of dietary Ptecticu tenebrifer powder mixtures as pet dogfeed ingredients on crude fat and ash digestibility. Three groups of feeds Feed A, Feed B, and Feed C supplied from three farms were fed to a total of 45 dogs. The dietary Ptecticu tenebrifer powder mixture were prepared by mixing 25 g of Ptecticu tenebrifer powder with 100 g of canned food. Feed A, Feed B, and Feed C containing dietary Ptecticu tenebrifer powder mixtures were fed to 15 dogs of each breed of bichon, poodle, and chihuahua that were divided into three groups following a completely randomized design. For measuring the crude fat and crude ash digestibility, manure of each dog breed from each group were collected. Crude fat digestibility was not statistically significant among the dog breeds fed with feed C (p>0.05), but overall there was a statistical difference between the feed and the group by dog breed (p<0.05). In terms of crude ash digestibility, the three types of feed showed differences with respect to dog breeds (p<0.05). However, the group with no significant difference was observed in Feed B by dog breed (p>0.05). In conclusion, feeding Ptecticu tenebrifer powder mixture to dog breeds had no positive effect on the crude fat and ash digestibility and can be used as pet dogfeed ingredients.

Apparent digestibility of three representative seaweeds commonly used in Korea was obtained through an animal experiment and their calorie values were calculated therefrom. 1) Digestion coefficients for the nutrients of laver were crude protein, 42%; crude ash, 9%; carbohydrate, 62% and crude fat, none. 2) Digestion coefficients for the nutrients of tang1e were crude protein, 10%; crude fat, 40%; carbohydrate, 40% and crude ash, none. 3) Digestion coefficients for the nutrients of green laver were crude protein, 38%; crude fat, 59%; carbohydrate, 66% and crude ash, none. 4) Calorie values of seaweeds on the basis of above digestion coefficients were assessed to be only 52% in laver, 32% in tang1e and 59% in green laver as compared with those customarily obtained from proximate composition and Atwater's coefficient.

This study aimed to investigate the effect of treating environmental purification insect larvae to pig manure on crude ash contents and ammonia production. The experiment set up consisted go two groups: 1 kg of each 3^rd instar TM (Tenebrio molitor) and 3^rd instar PBS (Protaetia brevitarsis seulensis) larvae in Experiment 1 or 3^rd and 4^th instar of HI (Hermetia illucens L.) larvae in Experiment 2 were treated with 5 kg of pig manure. In Experiment 1, the crude ash content was higher in TM larvae-treated pig manure at days 0 and 5 (p>0.05), but was similar to that in PBS larvae-treated pig manure over (p>0.05). Ammonia production was observed at day 0 of TM and PBS larvae-treated pig manure (p<0.05), but did not occur thereafter. For Experiment 2, there was significant difference in crude ash content of 3^th and 4^th instar HI larvae-treated pig manure on day 15. Additionally, ammonia production was found in 3^th and 4^th instar HI larvae-treated pig manure at days 0 and 5, but did not continue over time. In conclusion, treating TM, PBS and HI to pig manure changed the crude ash contents and reduced ammonia through the ability to decompose pig manure. Thus, environmental impact can be minimized using environmental purification insect larvae.

To investigate the effects of reduction of leaf processing factories on the uniformity of processed leaf quality, the contents and their C.V.(Coefficient of Variation) of chemical constituents of flue-cured leaf tobacco produced from 1997 to 2001 and processed at various factories were analysed. The average leaf chemical contents of 12 grades for 5 years ranged as follows ; nicotine 2.00∼0.85%. total sugar 10.7∼16.9%, total nitrogen 2.36∼2.78%, crude ash 14.6∼15.6% and chlorine 0.50∼0.75%. The variations of chemical contents among crop years was higher in total sugar content while lower in crude ash content. The C.V. of chemical content in same grade leaves was higher in chlorine content while lower in total nitrogen and crude ash contents, and the ratio of C.V. among processing factories/C.V. in total population was higher in total sugar content while lower in crude ash content. When the leaves were processed at one factory, the deviations of chemical contents reduced considerably. Particularly, the decreasing effect of deviation was higher in total sugar content.

Although each part of Trichosanthes kirilowii is frequently used as medicinal herbs, study on the chemical composition is not sufficient. It was found that sarcocarp consists of 70% of carbohydrate, 13% of crude protein, 5% of crude fat, 6% of crude fiber and 6% of crude ash; seed consists of 62.59% of carbohydrate, 12.75% of crude protein, 14.80% of crude fat, 6.50% of crude fiber and 3.36% of crude ash; and root consists of 89.40% of carbohydrate, 4.10% of crude protein, 0.50% of crude fat, 3.50% of crude fiber and 2.50% of crude ash. Sarcocarp and seed contain fifteen kinds of amino acids such as Asp, Ser, Glu, Gly, His, Arg, Thr, Ala, Pro, Try, Cys, Met, Val, Leu, and Phe. Sarcocarp contain large quantities of phenylalanine and glycine and seed does not contain leucine but lysine. The mineral contents in Trichoxanthes kirilowii are 0.55% Ca, 0.91% Mg, 10.29% Na, and 0.17% K.
