This study was conducted to investigate the effects of Oenanthe javanica and Allium tuberosum powder on lipid metabolism in rats fed high fat·high cholesterol diet. Experimental rats were divided into five groups which were composed of normal diet group (N), high fat·high cholesterol diet group (HF), high fat·high cholesterol diet with 5% Oenanthe javanica powder diet group (OP), high fat·high cholesterol diet with 5% Allium tuberosum powder diet group (AP) and high fat·high cholesterol diet with 2.5% Oenanthe javanica and Allium tuberosum powder diet group (OAP). The serum TG content of the HF group was significantly increased compared to the N group, but that of the OAP group was significantly decreased. Serum HDL-cholesterol contents of the OAP group was significantly increased compared to the HF group. The serum total cholesterol, LDL-cholesterol and AI of the HF group were increased compared to the N group and especially the LDL-cholesterol of OP and OAP groups were significantly decreased compared to the HF group. The liver TG and total cholesterol contents of the HF group were significantly increased compared to the N group, while TG contents of the OAP group was significantly decreased compared to the HF group. Fecal total lipid and total cholesterol of OP, AP and OAP groups were significantly increased compared to the HF group. These results suggest that supplementation of Oenanthe javanica and Allium tuberosum may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat·high cholesterol diets.
This experiment was conducted to investigate the effect of continuous feeding of probiotics on growth performance, nutrient digestibility, blood urea nitrogen(BUN) and immune responses in pigs. Treatments were 1) Control(basal diet), 2) P-O.l(basal diet + 0.1% probiotics) and 3) P-0.2(basal diet + 0.2% probiotics). In growth trial, a total of sixty pigs(6.17 $\pm$ 0.45 kg average body weight) weaned at 21 days of age were used. All pigs were assigned according to sex and body weight, and each treatment had 5 replicates of 4 pigs per pen in a randomized complete block(RCB) design. During 0${\sim}$8 weeks, there was no significant difference in average daily gain(ADG), average daily feed intake(ADFI) and gain:feed ratio(GfF) among treatments. During 9 - 20 weeks, ADG was improved significantly in pigs fed P-O.I or P-0.2 diets when compared to the pig fed control diet(P <0.05), but there was no significant difference in ADFI and GfF ratio. During overall period, ADG, ADFI and GfF ratio were not significantly different among treatments. In the first metabolic trial(17.93 $\pm$1.45kg average body weight), apparent digestibility of OM, protein, fat in pigs fed P-O.l and P-0.2 diets were greater than in pigs fed control diet(P <0.05) and ash digestibility in pigs fed P-0.2 diet was significantly higher than in pigs fed control diet(P <0.05). Calcium digestibility in pigs fed P-0.2 diet was significantly higher than in pigs fed control and P-O.I diets(P <0.05). Fecal-N excretion was lower in pigs fed P-O.! and P-0.2 diets than in pigs fed control(P <0.05). In the second metabolic trial(41.80 $\pm$ 2.68kg average body weight), there was no significant difference among treatments in apparent digestibility of nutrients and N-retention. In blood assay for the BUN and immune responses investigations, there was no significant difference among treatments during overall period of experiment. Therefore, this experiment suggested that probiotics supplementation could improve growth performance and nutrient digestibility of pigs.
The effect of different particle sizes of scoria inclusion in weanling-growing-finishing diets on growth performance and carcass quality was investigated in this study. Treatments were the control (basal diet), and 3 scoria treatments with different partical sizes (500, 1,000, 1,700 ${\mu}m$, respectively) in which $3\%$ of basal diet was replaced by scoria. This study was carried out for 143 days using 84 pigs. Each treatment has 3 replicates (4 gilts and 3 barrows per pen). 1. During nursery period, all scoria treatment levels showed poor Average daily gain (ADG) and feed efficiency compared to the control. During growing period, The ADG and feed efficiency of pigs fed the $1,000\;{\mu}m$ swine treatment tended to improve. For the whole growth period (d 0-143), $1,000\;{\mu}m$ scoria treatment showed significantly higher (P<0.05) ADG and feed efficiency than the $1,700\;{\mu}m$ scoria treatment. 2. Carcass weight was higher in all of scoria treatment levels Either the control (P<0.05), while backfat thickness was unaffected among treatments. Carcass Grade A or B grade appearance was more evident in all of scoria treatments compared to the control. 3. Hunter L value was numerically higher in the control while there was no significant differences among the control, $1,000\;{\mu}m$ scoria and $1,700\;{\mu}m$. Hunter a value was highest (P<0.05) in $1,000\;{\mu}m$ scoria, while Hunter b values were not influenced by the scoria treatment levels. 4. The different scoria treatment levels reduced N and P excretion. For growing period, $1,000\;{\mu}m$ scoria was most efficient in reducing N excretion, while during the finishing period, $1,700\;{\mu}m$ scoria was the best. The P excretion was affected by scoria particle size during growing-finishing periods rather than weanling period. The above findings indicated that the inclusion of different scoria partical sizes in nursery diet resulted to adverse effects on growth performance in contrast to the growing finishing diets wherein the growth performance and carcass quality were not affected. Finally, scoria regardless of particle size proved to be effective in reducing N and P excretion and can be considered an environment friendly mineral source for growing-finishing hog diets.
In this study, we evaluated the recovery effects of dietary fiber extracted from soybean hulls on diarrhea in rats. Diarrhea-induced Sprague-Dawley male rats were divided randomly into 4 groups and fed experimental diets for 24 hours. The diets, based on the AIN93G diet, were as follows: CON (control diet), S-COTL (67.2 g/kg soybean cotyledon fiber diet), S-HULL (59.6g/kg soybean hull fiber diet), CHI (55.6g/kg chicory fiber diet). The results showed significant (10-20%) reductions of fecal water content in the CON and S-HULL groups, as compared to the S-COTL and CHI groups. The change in serum osmolality, a measure of dehydration symptoms, was significantly reduced in CON and S-HULL as compared to the S-COTL and CHI groups. Based on the results, it is suggested that soybean hull fiber functions well for diarrhea recovery in rats. Consequently, soybean hull fiber is an important food source that could be used as a medical food in patients suffering from diarrhea.

These studies were conducted to evaluate the Properties of lactic acid Producing bacteria(LAB), isolated from broiler and laying hens cecum and select the optimum strains to improve the performance, environment of poultry house, immunity, and intestinal microflora of broiler and laying hens. In experiment I , 23 LAB strains were isolated from broiler and laying hens cecum as a colony form. Six strains were selected by acid tolerance, bile salt tolerance, viability, enzyme release, antagonism, and antibiotics susceptibility. In Experiment II, selected LABs from Ex. 1 were conducted to investigate the effects of feeding various Lactobacillus on performance, nutrients digestibility, intestinal microflora, villi development and observation of epithelium surface, blood chemicals and fecal noxious gas of broiler chicks. One thousand eighty one day old broiler chicks were fed into Lactobacillus crispatus avibrol(LCB), Lactobacillus reuteri avibro2(LRB), Lactobacillus crispatus avihen1(LCH), and Lactobacillus vaginalis avihen2(LVH) at the level of 10$^4$ and 10$\^$7/cfu/g diet. Weight gam of chicks fed Lactobacillus tended to increase from the first week and was higher from 50 to 100g in Lactobacillus treatments than control. Feed intake and feed conversion were not statistically different of all treatments. Dry Matter digestibility of Lactobacillus treatments was prone to improve compared to that of control, but was not significantly different. Protein and Ca digestibility were also tended to improve in Lactobacillus treatments relative that of control. Lactobacillus treatments showed improved tendency in crude ash and fat compared to those of control, whereas phosphorus digestibility was not consistency. Nutrients digestibilities of bird fed LCH were superior to those of other treatments, It showed significantly higher in Ca and P digestibility than control(P〈0.05). Total Lactobacillus spp. of birds fed various Lactobacillus was significantly higher in illeum for five weeks(P〈0.05), but was not different at cecum. Yeast was thought to be not completely attached to intestinal lumen for one week. However, total number of yeast was significantly increased in cecum and illeum of three weeks old chicks (P〈0.05). The number of anaerobes exhibited to tendency the increase in Lactobacillus treatments from one week old of age at both ileum and cecum.
In order to investigate an effect of non-protein nitrogen on the biological utilization of protein, hatched single comb White Leghorn male chicks were fed for the first 8 days with a commercial chicks mash, next 6 days with protein-free diet and subsequent 6 days with protein-free diets and protein diets containing 10.59% of crude protein supplemented with 0, 0.5, 1.0 and 1.5%, respectively. During experimental feeding period, chicks fed protein-free diets had intaked gradually lower feed and had shown a similar body weight loss though urea contents were increased. When birds fed protein diets, body weight gain and feed intake were not different among birds fed the graded levels of urea although feed conversions were shown a highering tendency along with increasing urea contents. According as supplemented urea were increased, protein efficiency ratio f (PER) and net protein ratio (NPR) were increased in chicks fed protein-free diets, which were shown a lowering trend in chicks fed protein diets. Effect of supplemented urea on the urinary excretion of uric acid were not found in birds fed protein-free diets, while which were increased in birds fed protein diets with the increase of urea contents. Urea addition did not affect the excretion of total creatine in birds fed protein-free or protein diets. Excretion of ammonia was jogjered in order to increasing level of urea in birds fed protein-free diets, but which were not found any particular effect in birds fed protein diets. Also urea excretion were gradually increased with the increasing contents of urea in protein-free and protein diets. Nitrogen balance of birds fed protein-free diets were minus values, which were increased with increasing urea contents in diets. When birds fed protein diets, nitrogen balance and urinary nitrogen excretion was highered and fecal nitrogen excretion were not altered as urea levels of diets increased. Digestibility of urea nitrogen supplemented in protein-free diets were lowered along with increasing contents of urea, but biological value(BV) and net protein utilization(NPU) was found a highering tendency in birds fed protein-free diet containing 1.5% of urea. When birds fed with protein diets, digestibility, BV and NPU of protein were found a highering trend in birds fed protein diets added with 0.5% of urea.
Two experiments were carried out to evaluate the effects of feeding Aspergillus oryzae(AO) ferment on performance, intestinal microflora, serum components, ammonia generation and litter dampness in broiler chicks. In experiment I, three hundred sixty, one day old broiler chicks, Abor Acres, were fed 0 and 0.1% of Aspergiilus oryzae short conidia ferment(AOS) and 0.1% of Aspergillus oryzae long conidia ferment(AOL) for five weeks. In experiment II, three hundred sixty, one day old broiler chicks, Abor Acres were fed 0, 0.1 and 0.2% of Aspergillus oryzae long conidia ferment(AOL) for five weeks. In experiment I, growth rates were not statistically different among dietary treatments. AOS and AOL showed increased tendency in weight gain and feed intake compared to those of control, whereas feed conversion was not different. Litter dampness of AOS and AOL was also tended to decrease compared to that of control, but was not significantly different. Fecal ammonia gas generation was decreased in feeding AOS and AOL, and maintained 1/2 to 3/4 compared to the control. In serum metabolites, AOS and AOL increased glucose and calcium, and decreased total protein, blood urea nitrogen and total cholesterol. In experiment II, body weight of chicks fed 0.1 and 0.2% AOL were heavier than the control(P<0.05). Feed intake of chicks fed 0.1 and 0.2% AOL also were higher than the none, but feed conversion ratio was not different among treatments. Ileal and cecal microflora showed increased tendency in lactic acid bacteria compared to those of the control. Salmonella and E. coli were decreased in ileum of chicks fed 0.1 and 0.2% AOL. In conclusion, feeding AO ferment increased growth performance and improved intestinal microflora of broiler chicks and environments of broiler house.

This study was. conducted to investigate the effects of $\delta$-aminolevulinic acid supplementation on growth. performance, nutrient digestibility and hematological changes in weaned pigs. Seventy five Duroc${\times}$Yorkshire${\times}$ Landrace pigs (7.21$\pm$0.02 kg average BW) were used in a 20 d growth assay. Dietary treatments included 1) NC (negative control; basal diet), 2) PC (positive control; NC diet + 0.1% Apramycin + 0.1% Oxytetracycline), 3) ALA0.l (NC diet+0.l% $\delta$-aminolevulinic acid), 4) ALA0.2 (NC diet+0.2% $\delta$-aminolevulinic acid) and 5) ALA + AB (PC diet+0.2% $\delta$-aminolevulinic acid). In entire experimental period, ADG (Average Daily Gain) was greater in pigs fed ALA + AB diet than in pigs fed NC diet (p<0.05). However, there was no significant difference in ADG for pigs fed PC, ALA0.l or ALA0.2 diets. Also, ADFI (Average Daily Feed Intake) and G/F (Gain/Feed) were not affected by treatments. For 20 d, fecal digestibilities of DM (Dry Matter) and N (Nitrogen) were higher (p<0.05) for pigs fed ALA + AB diet than for pigs fed NC and ALA0.l diets. Total protein concentration of serum was increased in ALA + AB treatment compared to NC and PC treatments (p<0.05). In iron concentration of serum, pigs fed $\delta$-aminolevulinic acid supplementation diets were greater than for pigs fed NC and PC diets (p<0.05). TIBC (Total Iron Binding Capacity) concentration of serum was increased in ALA + AB treatment compared to NC, PC and ALA0.l treatments (p<0.05). Pigs fed ALA + AB and ALA0.2 diets were higher hemoglobin (Hb) and hematocrit (HCT) concentration of blood than pigs fed NC and PC diets (p<0.05). RBC and WEC concentrations of blood were significantly higher (p<0.05) for the pigs fed ALA0.2 and ALA + AB diets than for pigs fed NC diet. Lymphocyte concentration of blood was increased in $\delta$-aminolevulinic acid supplementation treatment compared to NC treatment (p<0.05). In conclusion, $\delta$-aminolevulinic acid supplementation for weanling pigs had improved growth performance and nutrient digestibilities and had increased total protein, iron, hemoglobin and lymphocyte concentration of blood. Also, feeding for dietary $\delta$-aminolevulinic acid and antibiotic mixture supplementation may have more higher effective growth performance in weanling pigs.

Crataegi fructus has been used as an oriental medicine and a folk remedy for the treatment of scurvy, constipation and stomach ailment. This study was aimed to investigate the effect of fermented Crataegi fructus vinegar (FCV) on the improvement of lipid metabolism in rats fed high fat diet (40% kcal% fat, fat source; beef tallow). Sprague-Dawley rats (n=32) were randomly divided into four groups [normal diet (ND), high fat diet (HD), and high fat diet supplemented with low (CFL; 1.5% wt/wt) and high (CFH; 3.0% wt/wt) doses of fermented Crataegi fructus vinegar] and were fed experimental diets for 6 weeks. At the end of the experiment, the body weight in high fat diet groups was higher than that of normal diet group, while the body weights of CFL and CFH group were significantly reduced by 7.2% and 10.0%, respectively, as compared with that of HD group. Moreover, liver and kidney weights in CFL and CFH group were significantly lower than that of HD group (p<0.05). The levels of serum triglyceride, total cholesterol, LDL-C, atherogenic index and hepatic triglyceride, total cholesterol in CFH group were significantly decreased as compared with HD group whereas it increased the serum level of HDL-C than HD group (p<0.05). CFL and CFH groups showed significantly decreased AST, ALT and ALP of serum as compared with HD group. Excretions of fecal saturated fatty acid in CFH group was significantly increased compared with ND and HD groups. These results imply that fermented Crataegi fructus vinegar can be used as possible food resources and functional food materials.
