This experiment was conducted to study the effects of medicinal plant extract on performance in broiler chickens. A total of eight hundred forty, 1-d-old broiler chicks(Ross) were randomly allocated to 7 treatments with 4 replicates of 30 birds per replicate. The treatments were negative control (NC, diets without antibiotics), positive control (PC, diets with-containing antibiotics), Schisandrae fructus (T1), Scutellariae radix (T2), Camellia sinensis (T3), Artemisia capillaris (T4) and mixed medicinal plants (T5) extracts added to drinking water. The final body weight, body weight gain and feed conversion rate were significantly improved in all treatments compared to NC (P<0.05). No significant differences were observed in the relative weights of liver, spleen, pancreas, bursa of Fabricius and intestinal tract among the groups. The relative lengths of duodenum, jejunum and ileum were significantly decreased in PC compared with other groups (P<0.05). No significant differences were observed in the cecal microflora. The contents of triacylglycerol (TG), blood urea nitrogen (BUN), glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) in blood serum were not significantly influenced. The concentration of cholesterol in blood serum was significantly decreased in all treated groups as compared to those of the control (P<0.05). There was no difference in the components of leukocytes and erythrocytes among the groups.

The screening of anti-cancer activity for the MeOH extracts of 163 natural sources, which were registered as edible plants by Korea Food & Drug Administration, exhibited 9 extracts to have significant inhibitory effects on farnesyl-protein transferase (FPTase) and phosphatase of regenerating liver-3 (PRL-3). In order to confirm the inhibitory activity of these active extracts, the activity assay was repeated for some fractions obtained from the active extracts using Medium Pressure Liquid Chromatography (MPLC). Some fractions of Carya illinoensis, Chlorella vulgaris, Panicum miliaceum, Perilla frutescens, Rosmarinus officinalis showed over 50% inhibitory activity on FPTase as well as those of Capsella bursa-pastoris, C. illinoensis, C. vulgaris, Coix lacrymajobi, Myristica fragrans, P. miliaceum, R. officinalis did over 50% inhibitory activity on PRL-3.

An experiment was conducted to study the performance of broilers chicks (2 to 42 d of age) fed diets containing pearl millet (PM, Pennisetum typhoides), foxtail millet (FOM, Setaria italica) or finger millet (FIM, Elusine coracana) totally replacing (w/w) yellow maize (YM) with and with out supplementing non-starch polysaccharide (NSP) hydrolysing enzymes at the rate of 0.5 g/kg diet. Enzyme preparation contained amylase 2,400 units, hemi-cellulase 5,400 units, cellulase 12,000 units, protease 2,400 units and beta-glucanase 106 units/g. Each diet was fed to eight replicates (five female Vencob broilers/replicate) housed in stainless steel battery brooders. The estimated metabolizable energy (ME) contents of YM, PM, FOM and FIM were FM (PM) were about 3,389, 2,736, 3,303 and 2,846 kcal/kg, respectively. Total replacement of YM with FOM did not influence the body weight gain, ready to cook yield, relative weights of giblet, liver, intestine, lymphoid organs (bursa and spleen) and length of intestine, antibody titers and livability at 42 d of age. But the food efficiency decreased significantly in FOM fed broilers compared those fed YM. Further, the fat content in thigh muscle reduced with FOM fed groups compared to those fed YM. The performance of broilers decreased significantly in PM and FIM fed broilers compared to those fed YM. The relative weights of giblet, gizzard and liver increased in FIM fed groups compared to those fed YM as the principal source of energy in broilers. Incorporation of NSP hydrolysing enzymes in commercial broiler diets improved the efficiency of feed utilization during starter phase but not at 42 d of age. The results thus indicate that yellow maize can be replaced in toto on weight basis in commercial broiler diets without affecting the performance. Supplementation of NSP hydrolysing enzymes was beneficial in enhancing feed utilization during the starter phase.

Two experiments were conducted to evaluate the efficacy of dietary FERMKIT, a commercial toxin binder consisting of probiotic-fermented natural product containing chitin, chitosan and chitosan oligosaccharides ($FERMKITO^{(R)}$, EASY-BIO SYSTEM, Inc., Korea), in binding aflatoxin (AF) and zearalenone (ZEN) and ameliorating their mycotoxicity in meat type ducks. FERMKIT was supplemented to AF contaminated diets (at 120 ppb) at either 0.3 or 0.6% in experiment 1 and to ZEN contaminated diets (at 150 ppb) at 0.6% in experiment 2. In experiment 1 body weight gains were reduced by 37% and mortality was increased by 18% in ducks fed diet contaminated with AF at 120 ppb compared to ducks fed control diet (<10 ppb AF) for the 4-wk experimental period. However, dietary FERMKIT supplementation effectively alleviated overall toxicity induced by AF. The significant treatment-related changes in feather growth, web-toe hemorrhage, leg deformity, liver paleness, organ weights, hematological values and serum biochemical values, as compared to the control, were observed. The FERMKIT supplementation significantly diminished the adverse effects of AF and restored all the parameters measured back (<0.05) toward the control values. These findings indicated that FERMKIT, when added at the levels of 0.3 or 0.6% in the 120 ppb AF diets, could modulate the toxicity of AF with percentage sorption capacity of 52.70% at the level 0.3% and 79.85% at the level 0.6% of the diets (experiment 1). In experiment 2, FERMKIT, when added at 0.6% to the 150 ppb ZEN diets for the 4-wk experimental period, diminished the toxicity as shown by body weight gain, weights of testicles, oviducts, Bursa of Fabricius and cloaca eversion score as compared with the controls (<10 ppb ZEN) and 150 ppb ZEN diet with no added FERMKIT. The findings indicated that FERMKIT could be protective against the effects of ZEN in young growing ducks with percentage sorption capacity of 67.11% as evaluated from toxicity index parameter measured when added at 0.6% of the diets containing 150 ppb ZEN.

This study represented an endeavor to observe clinical signs and pathological lesions in broiler chicks suffering from experimental Infectious stunting syndrome(ISS). One hundred and twenty day old broiler chicks were divide randomly into two equal groups i.e. control (A) and inoculated (B). At day one of age each chick of the groups (A and B) was dosed with one ml of either tryptose phosphate broth or prepared inoculum respectively. Chicks of both the groups were housed separately under similar standard management. Inoculation induced characteristic clinical changes in birds of treatment group like of brownish diarrhea, lameness, feather developing problems and paleness of combs, wattles and shanks. By day-29 of the experiment all the stunted birds from group-B and an equal number of birds from group-A were slaughtered. These birds were examined thoroughly to record the gross changes in various structures and then the severely affected organs were processed for histopathological examination. The skeletons of affected birds were brittle, keel bones showed quite prominence while the muscles and subcutaneous tissues were almost devoid of fat. Grossly it was observed that pancreas, spleen and bursa of Fabricius were severely atrophied while the intestines were ballooned with undigested feed and gases. Histopathological examination of pancreas and spleen revealed a classical picture necessary for understanding the pathogenesis of the syndrome. The acivar cells of pancreas were atrophied and underwent vacuolation, degeneration and vecrosis. The zymogen granules were almost absent from the acinar cells. A characteristic change was an inflammatory reaction in one or more pancreatic ducts where the epithelium and fibrous tissues occluded the lumen of the ducts and led to the obstruction in pancreatic drainage.

Different levels of dietary mannanoligosaccharide (Bio-MOS, Alltech Inc.) were evaluated for their efficacy on performance and gut development of broiler chickens during a 6-week experimental period. Experimental diets contained (g MOS/kg diet) a low (0.5 g during the entire period), medium (1 g during the entire period), high (2 g during the entire period), or step down (2 g in the first week; 1 g in the second and third week; 0.5 g in the last three weeks) level of MOS. Control diets included a negative and a positive control (zinc bacitracin, ZnB, 50 ppm and 30 ppm in the first and last three weeks, respectively). MOS supplementation improved the growth performance of young birds and the effects became less when the birds got older. The growth response of birds was more obvious at the high dosage level of MOS treatment than the other MOS treatments and the growth performance of birds fed on the high MOS diet was comparable to that of birds fed on the ZnB diet. Depending on the dosage level and the age of birds, MOS seemed to reduce the size of the liver and the relative length of the small intestine but did not affect the relative weight of the other visceral organs (proventriculus, gizzard, pancreas, bursa and spleen) and that of the small intestine. A numerical increase in the small intestine digestibility of nutrients was noticed in the young birds fed on the MOS diet(s), but not in the older ones. Medium and/or high MOS treatment also increased the villus height of the small intestine of birds at different ages. Similar results were observed on the ZnB treatment. However, MOS and ZnB affected caecal VFA profile in different ways. MOS increased, or tended to increase, whereas ZnB reduced individual VFA concentrations in the caeca.

The objectives of this study were to investigate the immune responses of broiler chickens fed diets supplemented with different level of chromium methionine (CrMet) in heat stress (HS) condition. Two hundred and eighty eight male broiler chickens (Ross 308) were allocated to four treatment groups (supplementation with 0, 200, 400 or 800 ppb Cr in the form of CrMet) in a completely randomized design. The experiment was conducted at heat stressed condition and all birds were kept under temperature of $33{\pm}2^{\circ}C$. Antibody titers against Newcastle disease virus (NDV) and infectious bronchitis virus (IBV), heterophil to lymphocyte ratios (H/L), and concentration of plasma cortisol (CPC) were measured at 21 and 42 d. At 42 days of age two birds were chosen randomly from each replicate, slaughtered, spleen and bursa of Fabricius were collected, weighed and expressed as a percentage of live body weight. Antibody titers against NDV and IBV at 21 and 42 days of age in broiler fed supplemental CrMet were higher than in broiler chickens fed control diet (p<0.05). CPC level in broiler chickens fed CrMet were significantly (p<0.05) decreased. Increases in lymphocyte counts and consequently a decrease in heterophil to lymphocyte ratios in broiler chickens fed 800 ppb Cr were observed at 21 and 42 d. Supplementation with CrMet had no significant effect on lymphoid organs of broilers. The results suggest that dietary CrMet supplementation at a level of 800 ppb can improve some immune responses of broiler chickens under heat stress conditions.
