A total of 60 growing pigs (25.50 ± 1.63 kg) were used in a 6-week trial to investigate the effects of diet supplementation with brewer's yeast (Saccharmyces cerevisiae) on growth performance, nutrient digestibility, and fecal score of growing pigs. Pigs were randomly allocated to one of two dietary treatments [six replications (five pigs·pen^-1)] according to initial body weight. The dietary treatments included: 1) control, basal diet (CON); 2) basal diet supplemented with 1% brewer's yeast. Dietary supplementation with brewer's yeast showed significant improvement in body weight (BW) at weeks 4 and 6; the average daily gain (ADG) and gain : feed ratio (G/F) was higher during week 4 and overall compared with CON (p < 0.05). Brewer's yeast supplementation in the diet had no significant on the nutrient digestibility. There was no significant difference in the fecal score of CON and brewer's yeast supplementation in the diet. In conclusion, the results indicate that dietary supplementation with brewer's yeast can improve growth performance in growing pigs. The results showed that supplementation of brewer's yeast in the diet of growing pigs had a positive effect on the ADG in growing pigs, but no significant effect on nutrient digestibility and fecal score when supplemented with brewer's yeast in the diet of growing pigs.

The utilization of feeding white sweet lupin (Lupinus angustifolius cv. Uniwhite) seeds supplemented with the limiting amino acids were investigated in day-old single comb White Leghorn male chicks. These were fed a commercial chick mash for the first 10 days and on a semi-synthetic protein-free diet for the next 6 days. For the subsequent 6 days of experimental feeding period, the birds were fed on the protein-free diet, basal diet containing 9.31% of lupin seed meal (LSM) protein, diets supplemented with methionine, methionine + tryptophan or methionine + tryptophan + lysine in the basal diet, and diet containing 9.84% of soybean meal (SBM) protein. When the LSM protein was supplemented with methionine, protein intake, body weight gain, protein efficiency ratio (PER) and net protein ratio (NPR) were increased (p<0.05). The birds excreted lower urinary nitrogen and fecal nitrogen per protein comsumption, had improved apparent (AD) and true (TD) digestibility but did not alter biological value (BV) of the protein. Metabolizability (MEn/GE) and heat production (HP) per MEn intake (HP/MEn) was lowered while energy retention (ER) was highered (p<0.05) compared with those of the basal diet. Also the body weight gain, PER, NPR and ER was increased but the BV and HP/MEn was lowered compared with those of the SBM protein. The results indicated that lupin seed supplemented with methionine increase body weight gain and energy rentention but did not alter biological value compared with those of lupin seed and soybean meal.

The purpose of this study was to investigate the improvement effect of 5% turmeric (Curcuma longa L.) on the blood glucose and lipid metabolism function of streptozotocin (STZ, 45 mg/kg body weight)-induced diabetic rats. Seven-week-old male rats were divided into four groups (n=6), and fed experimental diets containing turmeric meal [basal diet+5% turmeric (BT), basal diet+STZ+5% turmeric (ST)], and control (BD), BS groups (basal diet+STZ). The results of this study, turmeric diet groups (BT, ST) in lipid component as evidenced from the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, uric acid, blood glucose, non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol). The serum albumin and globulin contents were increased in turmeric supplementation diet than STZ-induced diabetic rats (p<0.05). Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the turmeric diet than diabetic group. Total calcium (T-Ca), phosphorus (Pi) and potassium (K) concentrations in sera were higher in the BT, ST and BD groups than BS group. In vivo experiments with Sprague-Dawley rats showed that ingestion of turmeric (Curcuma longa L.) were effective in the blood glucose and lipid metabolism functional improvement.

Two hundred 10-day-lid, male Arbor Acres broiler chicks divided randomly into 4 groups of 50 chicks each were used. Different feeding treatment was carried out for each group. Chicks in treatment 1 were fed a basal diet(Starter feed)(control); treatment 2, a basal diet + 0.1% B. subtilis culture; treatment 3, a basal diet + 0.2% lactobacilli culture in the feed; and treatment 4, a basal diet + 5 g lactobacilli in the drinking water. The viable bacterial counts for each treatment were approximately $10^9cells/kg$ feed. The weight gain in chickens given feeds incorporated with B. subtilis and lactobacilli was significantly(p < 0.05) higher than those of the control. With regard to feed efficiency, there was a definite tendency towards a higher feed : gain lower(p < 0.05) feed : gain ratio. A significantly(p < 0.05) larger population of Lactobacillus was found in the small intestine of chickens fed with feed incorporated with B. subtilis at 21 and 28 days and with lactobacilli at 14, 21 and 28 days. Populations of intestinal E. coli in broilers given feed added with B. subtilis were not significantly(p < 0.05) different from those of the control, but in chickens fed lactobacilli-added feed, their populations wee significantly lower(p < 0.05) at 14 and 21 days. No significant differences were found among the treatments and the control in the occurrence of Salmonella and Campylobacter during the whole experimental period.

The aim of this study was to evaluate the potential of fermented red ginseng extract (FRGE) as feed additive in broilers and laying hens. In broilers, 480 Arbor Acre male broilers were randomly allotted to 4 treatments with 6 replications per treatment and 20 chicks per pen. The experiment lasted 5 weeks and dietary treatments were as follows: i) CON, basal diet; ii) FRGE1, basal diet+1 g/kg fermented red ginseng extract; iii) FRGE2, basal diet+2 g/kg fermented red ginseng extract and iv) FRGE3 basal diet+4 g/kg fermented red ginseng extract. Throughout the experiment, no effects were observed (p>0.05) in performance in response to FRGE. At the end of the experiment, FRGE administration improved (p<0.05) the lymphocyte level compared with CON. The relative weight of bursa of fabricius and spleen were increased (p<0.05) by the inclusion of FRGE3. Besides, redness ($a^*$) value for the breast meat was higher (p<0.05) in FRGE1 and FRGE3 treatments than that in CON. In laying hens, 240 ISA brown layers at 35 weeks of age were used in this 8-week trial. Dietary treatments were the same as in the broilers trial with 10 replicates per treatment and 6 layers per replicate. During the entire experiment, there were no significant differences (p>0.05) in performance or egg quality among all the treatments. However, the layers fed diets supplemented with FRGE had higher lymphocyte level (p<0.05) compared with those fed CON. In conclusion, the dietary supplementation with FRGE did not influence performance but improved the lymphocyte level in both broilers and laying hens.

A study was carried out to determine the probiotic effect of Lactobacillus reuteri BSA-131 by investigating the growth performance and fecal microbial population of piglets. Five dietary treatment groups, the basal diet (control, BD), basal diet with antibiotics(BA), basal diet with 2$\times$106/g of probiotics (BP6), 2$\times$108/g of probiotics (BP8) and basal diet with antibiotics and 2$\times$108/g probiot-ics(BAP8) were divised. Each dietary treatment group was consisted of 1 month of age piglets(male 13, female 12). Fecal micro-flora, body weights and feed consumption were measured at before, after and stop feeding of probiotics. The results showed that the CFU of fecal Enterobacteriaceae of piglets of the group BA, BP6, BP8 and BAP8, were reduced (P<0.05) compared to control BA. On the contrary, Lactobacillus counts were increased significan시 (P<0.001) in all groups fed probiotics dites, but not antibiotics. Body weight of probiotics treated piglets were improved 5% (p<0.001) in BP6 group than that of control group and antibiotic treated piglets BAP group was 27% (P<0.001) higher than BA group. The amount of feed consumption value of probiotics treated piglets showed 21-30% (P<0.001) lower intake than the control group, whereas antibiotic treated piglets BAP was 20% (P<0.001) higher than BA group. The results showed that body weights and feed to gain ratios were improves 19% when compared to control piglets for groups fed diets probiotic. It is very suggestive that productivity of probiotic piglets would be economical in pig farming.
