This experiment was conducted to evaluate the potential for dietary garlic powder(GP) on overall growth performances and cholesterol metabolism in broiler chickens. 1-d-old male chicks were fed diets containing 0 ％(with or without antibiotics), 1 ％, 3 ％ and 5％ GP for 6wk. Body weight gains in GP 3 ％ and 5 ％ groups were significantly higher than that of control without antibiotics. The content of tissue cholesterol in GP containing diet groups tended to be reduced as compared to those of control. The expression of hepatic HMG-CoA reductase mRNA was reduced consistently by dietary GP. IB antibody titer In chicks fed GP containing diets was significantly higher than control without antibiotics.

The present study was conducted to investigate the effects of dietary supplemental dry powder of Rehmannia radix (RR) root on the growth performance and physiological status of broiler chicks. The treatments consisted of corn-soybean meal control diet, and RR 0.5, 1, and 2％ diets. A total of 160 Arbor Acre male broiler chicks were randomly allotted to 16 pens ; four pens per treatment and 10 birds per pen. The growth performance, feed intake and carcass weight did not show any differences among the treatment groups, but feed conversion was significantly lower (P< 0.05) in RR 1％ group than that of the control group. The muscle color was lighter (P < 0.05) in RR lof group than those of the other treatment groups. The blood concentrations of protein, glutamic-oxaloacetic-transaminase (GOT) and glutamic- pyruvic-transaminase (GPT) were not different (P > 0.05) among the treatment groups, but the blood total cholesterol content was significantly decreased (P < 0.05) in RR 2％ group than those the other treatment groups. The blood concentration of sugar was lower (P <0.05) in RR 2％ group than those of the other treatment groups, and hemoglobin concentration was decreased (P <0.05) by addition RR. Crude fat content of thigh muscle was higher in RR 1％ group than those of the other treatment groups, and bone hardness of broiler chicks fed RR was higher (P < 0.05) than that of the control group. The saturated fatty acid content of the thigh muscle tende to be high in control and RR 0.5％ groups, and unsaturated fatty acid content tende to be high in RR 1 and 2％ groups than those of the other treatment groups

This study was conducted for improvement of meat quality in broiler chcikens. Birds were fed basal diet(control), ferritin, illite, betafin, or wood vinegar counting broiler feed according as broiler growth stage. Birds fed with basal diet, which was distributed under the best environmental condition, were more weight gain than other groups reared under same environmental condition. In the mean weight gain, the ferritin-group showed the highest and the illite-group showed the lowest among the feed additive groups; therefore, the effect of feed requirement change in odor reduction in illite and methyl saving of betafin was lower than those of other feed additives along to pass rear time. Meat quality was appraised by National Livestock Research Institute of RDA. Except the control-group, that had the best feed conversion ratio, the cooking loss of the illite-group was the biggest among groups although the illite-group chickens had a good water hold capacity. Therefore, illite is not good for making merchandise by reason that group chickens get reduction carcass weight after slaughter. On the other hand, the ferritin-group got the highest point of shear stress, cooking loss, and crude fat level. That group showed the best appraise in both breast and leg of sensory test in company and also feed conversion ratio was the highest among feed additive groups. As a result, the ferritin-group might use for making new merchandise among the feed additive groups.

Diets containing 0.02 to 10.0% EM-fermented orange (EFO) were fed to Paralichthys olivaceus(8.5 g), which were reared in flow-through system for 16 weeks. Groups fed on diets containing 0.1 and 0.2% EFO grew significantly faster; their feed coefficient and daily feeding rate were also higher. The number of goblet cells present in the mid-intestine of the fish receiving dietary EFO was significantly more. Total cholesterol level in plasma of the fish fed with 0.02% EFO was lower. However, there was no significant difference in GOT and GPT among the groups receiving different levels of EFO.

The effects of dietary $\beta$-glucan administration on non-specific immune parameters in common carp, Cyprinus carpio, (1.0 g and 68.7 g of body weight) and flounder, Paralichthys olivcaces (12.1 g and 54.0 g of body weight) were evaluated. All fishes were fed an experimental diet supplemented with $\beta$-glucan at $0.1\%$ per kg diet for 5 weeks. A week intermission with basal diet occurred between first 2 weeks and second 2 weeks of $\beta$-glucan administration, The changes in the numbers of peripheral neutrophils and macrophages were counted under light microscopy and serum lysozyme activity was also analysed at a week of interval during the experiment. Phagocytic activities of leucocytes from the swimm bladder of carp and the peritonium of flounder were measured 5 weeks after feeding. The oral adminisration of $\beta$-glucan induced significant reduction in mortality after an artificial challenge with $1\times10^6$ cells of Aeromonas hydrophila in larger carp and $1\times10^5$ cells of Edwardsiella tarda in larger flounder but did not in other groups. The numbers of peripheral macrophages and neutrophils, phagocytic acitivies of leucocytes, and the activity of serum lysozyme were greatly increased in the fish fed a $\beta$-glucan supplemented diet. These suggest that $\beta$-glucan administration by oral route can enhance leucocyte phagocytic activity, serum lysozymal activity, and survival rate against artificial infections depending on the infected fish size and challenged bacterial concentration.

This study was carried out to improve water thestability of extruded shrimp feed. Three types of extruded shrimp feeds which were control diet (no steaming, no wheat gluten), steaming treated diet and steaming treated diet containing wheat gluten were prepared to using the pilot scale extruder. Comparing with the water stability values of two types of extruded shrimp feed, Steamed shrimp feed containing 4% (w/w) wheat gluten showed on I after 48 h was better than the control diet (no steaming, no wheat gluten) of which water stability value was 4. Also Penaeus chinensis fed on the steamed feed showed good body weight gain (237%) and feed efficiency (16.7%) compared with body weight gain (151%) and feed efficiency (12.8%) of control diet in the feeding trial for 50 days. Briefly, the extruded shrimp feed has more efficient water stability on below I, and recommendable wheat gluten content and steaming time were 4∼8% (w/w) and 5∼10 minutes.

Effects of dietary killed salmonella and vancomycin on the performance and immune response was investigated in broiler chicks inoculated with Salmonella typhimurium. During 3 week(27 d) of age, experimental diet did not affect daily gain, feed intake and feed efficiency. Dietary killed salmonella and vancomycin decreased MnSOD activity. At 7day after Salmonella typhimurium inoculation, dietary killed salmonella and vancomycin increased, daily gain and feed efficiency of broiler chicks. At 7 and 15 day after salmonella inoculation, dietary killed salmonella and vancomycin decreased erythrocyte peroxidase activity, but elevated proliferation of PBMC stimulated with LPS and supernatant IL-1 level secreted by the PBMC. The results suggested that dietary killed salmonella and vancomycin improved the performance of broiler chicks due to modulate antioxidant system and innate immune response of broiler chicks innoculated with Salmonella typhimurium.

This study was conducted to investigate the effect of dietary wormwood powder (Artemisia montana Pampan; WP) supplementation on growing performance and fecal noxious gas emission in weanling pigs. One hundred and twelve pigs were alloted into four treatments and offered for 4 weeks one of the diets supplemented with 0% (control), 0.5% (0.5), 1.0% (1.0) and 2.0% (2.0) WP. Each treatments has four replicate with 7 pigs per replicate. ADG, ADFI and F/G were improved by 1.0 and 2.0 WP supplementation during 0d${\sim}$14d feeding. Feed intake of 1.0 WP diet was higher (P<0.05) than any other diet during 15d${\sim}$28d feeding. But there were no differences among the other treatments in the weight gain and feed conversion. During the whole feeding period, daily weight gain and feed intake of pigs fed 1.0 and 2.0 treatments were higher than those of pigs fed control and 0.5 diet. DM digestibility was significantly (P<0.05) higher in weanling pigs fed 0.5, 1.0 and 2.0 WP than that of the control. The protein digestibility was significantly improved in 1.0 WP treatment and the phosphorus digestibility was improved in 2.0 WP treatment. Excretion of nitrogen and phosphorus was significantly (P<0.05) decreased by 2.0 treatment than control. Emission of fecal ammonia after 48 hours storage in vinyl bag dramatically decreased by all the treatments except control. However, there was no statistical difference in fecal hydrogen sulfide emission among treatments. In conclusion, this study suggested that the dietary 1.0${\sim}$2.0 supplementation of WP can improve productivity of pigs decrease fecal $NH_3$ and $H_2S$ gas emission.
