This research was conducted to investigate the antibacterial activity of powder of temulawak, ginger and garlic to S.typhimurium using modified agar well method. Preliminary study showed that garlic powder had the best antibacterial activity, therefore it was further tested in a feeding trial to evaluate the effect on growth performance and immune response in broiler chicken challenged with S. typhimurium (ST). Experimental treatments were arranged in Completely Randomized Design with four treatment and three replications (Negative control, positive control, garlic powder and tetracycline). Seventy-two Day-Old-Chickens with body weight 46,7 g strain Ã¢â&sbquo;¬Å“Hubbard WonokoyoÃ¢â&sbquo;¬Â were used in a 28 days experiment. Broiler chickens were fed garlic powder and tetracycline diets for 10 days and then challenged orally with ST 4,1 x 1011 cfu. Body weight, feed intake and salmonella colony in faeces were monitored. Blood serum was collected at 18-d after infection. Results indicated that there was no significant effect of garlic powder on body weight and feed intake, but feed intake tended to decrease. However, feed conversion ratio of ration with garlic powder was better than rations with tetracycline and other treatments. Salmonella population in faeces also decreased with addition of garlic powder in diets. Total protein serum was influenced by disease challenged. Serum immunoglobulin (gamma globulin) was not influenced by disease challenged, but addition garlic powder in diet tended to increase gamma-globulin concentration. It can be concluded that garlic powder has antibacterial activity to S.typhimurium. Furthermore, this result indicated that some beneficial effect of dietary garlic powder at 2,5% supplementation on growth performance and no effect on immune response in the presence of ST-challenge. Key words : antibacterial, temulawak, ginger, garlic, Salmonella, chicken

The objective of this experiment was to determine the effect of bay leaves (S. polyanthum (Wight) Walp) used in the diet as E. coli antibacteria in improving broiler performances. This experiment used 180 day old chicks (DOC) of Cobb strain which were kept in litter system for five weeks. The experiment used completely randomized design with six treatments and three replications consisting of 10 broilers in each replication. The treatment diets were R0 = control diet, R1 = R0 infected with E. coli, R2 = R1 + 1% bay leaves, R3 = R1 + 2% bay leaves, R4 = R1 + 3% bay leaves, R5 = R1 + antibiotic. The data were analyzed with analysis of variance. The variables observed were feed consumption, body weight gain, final body weight, feed conversion ratio, mortality, and total colony of E. coli in broiler excreta. The results showed that the use of bay leaves up to 3% in the ration increased broiler performance by increasing feed consumption and body weight gain, depressing the number of E. coli in excreta, and reducing mortality compared to the other treatments, but it did not affect the feed conversion ratio. Key words: bay leaves, antibacteria, E. coli, broiler performance

Diarrhea is one of diseases in broiler chicken. Antibiotics are usually used to cure the disease. However, there are many risks caused by the use of antibiotic in poultry industries for human health. The risks are carcinogenic effect and resistance to the antibiotics. Therefore the use of antibiotics needs to be replaced by natural antimicrobes. One of the natural antimicrobes is bay leaves which contains volatile oils, tannins and flavonoids. This research was conducted to study the effect of bay leaves powder addition in the ration on the body weight, carcass percentage, carcass commercial cut and carcass cholesterol of the broiler using completely randomized design with six treatments and three replications. The research used 180 DOC (Day Old Chicken). The treatment diets were: R0 (control), R1 (control with infected Eschericia coli), R2 (1% bay leaves powder), R3 (2% bay leaves powder), R4 (3% bay leaves powder), R5 (antibiotic). The data were analyzed using analyses of variance and any significant difference was further tested by Duncan test. The results showed that the treatment diets did not significantly increase body weight, carcass percentage, and carcass commercial cut percentage. The treatment significantly decreased carcass cholesterol level. It is concluded that bay leaves meal could replaced the use of antibiotic in broiler ration and reduced carcass cholesterol. Key words: bay leave, E. coli, body weight, carcass, cholesterol

The objective of the present experiment was to evaluate the utilization of bay leaf (Syzygium polyanthum (Wight) Walp.) in the diets as antibacterial agent and its effect on the weight viscera organ of broilers. The experiment was arranged in a completely randomized design with six treatments and three replications. One hundred and eighty birds of five week-old broiler were used in the present experiment, and thirty six birds were decapitated to measure the weight of viscera. On day four, experimental animals were divided into six group of treatments and were provided standard diet. The treatments were as follows, Escherichia coli (E.coli)-uninfected broiler without bay leaf (R0/positive control goup), E. coli-infected broiler without bay leaf (R1/negative control group), R1 + 1% bay leaf (R2), R1 + 2% bay leaf (R3), R1 + 3% bay leaf (R4), and R1 + 0.02% tetracycline (R5). The results showed that weight percentage of liver, spleen, heart, pancrease, bile and intestine were not affected by the addition of 1, 2 and 3% bay leaf (R2,R3 and R4) as compared to those of R0, R1 and R5. However, gizzard percentage of broiler given 3% bay leaf (R4) increased (P < 0.01) to the value same as that of R0 (2.31 vs 2.71%). The highly significant (P < 0.01) increased in weight percentage of kidney was also found due to the treatments, and the increase was significant (P < 0.05) when R5 compared to R2 and R4. The addition of 2% (R3) and 3% (R4) bay leaf and 0.02% tetracycline (R5), as compared to R0, R1 and R2, could depress the number of E. coli in the excreta. In conclusion, the addition of bay leaf up to 3% was able to minimize the number of E. coli in excreta without negatively affecting weight of viscera of broiler chickens.

The problem with low meat production is caused by several factors, ie: management, feed and animal health. The development of integration system such as cattle-rice, cattle-corn and cattle-palm oil aims to utilize feed from local resources. However, sometimes local feedstuff causes a problem of imbalance nutrient. There are several strategies to overcome this problem and one of them is the use of feed additives from natural substance or plant resources such as lerak (Sapindus rarak De Candole). This research was aimed to utilize lerak fruit to improve performance and evaluate some blood profiles of Ongole crossbred cattle. The in vivo work was done using 12 Ongole crossbred cattle receiving 3 different feeds as treatment, i.e. 1) feed without lerak (high roughage diet) as control, 2) feed contained 2,5% lerak, and 3) feed contained 5% lerak. Growth, daily gain, blood profiles (leucocytes, cholesterol, trigliceride and globulins) were observed. The results showed no significant differences for nutrient intake, meaning that the ration has good palatability. Average daily gain of cattle fed with 2,5% lerak was 20% higher than those with control diet. White blood cells tended to decrease caused by lerak treatments, but the globulin profiles (alpha, beta and gamma) were not significantly affected in all treatments. Blood cholesterol concentration decreased following the increase of lerak percentage. It is not recommended to use lerak in the cattle ration for more than two months because of the decreasing of leucocytes. Key words: Sapindus rarak, in vivo, leucocytes, globulins, palatability

The present experiment was aimed to identify the phytochemical of Jatropha curcas leave extracted with water and methanol as an anthelmintic agent for Ascaridia galli, and its effect on native chicken performance. In vitro study of anthelmintic activity was conducted by counting the number of paralyzed worm dead-body of A. galli during 18 hours in petri dish containing different levels of extract, namely 0%, 1%, 2%, 3%, and 4% (w/v) and compared to the piperazine 0.5% (w/v). Eightteen birds of naturally A. galli-infected native chicken were used for the in vivo study. The treatments were 0%, 2%, 4%, 8%, and 16% of J. curcass leave extract, and 10% of piperazine using a completely randomized block design with 6 treatments and 3 replications. Parameters observed were fecal worm egg count, feed consumption, body weight gain, feed conversion ratio, and mortality. The results showed that water- and methanol-extracted J. curcas leave had similar composition of secondary metabolite compounds which is high in triterpenoid and steroid contents, respectively. Percentage of paralyzed A. galli was higher (P < 0.01) in water-extracted jatropha leaves. On the contrary, the dead-body percentage was higher (P < 0.05) in the methanol-extracted than that in the control group. In vivo study showed that leave meal significantly decreased (P < 0.05) fecal worm egg count. The leaf meal at the level 16% tended to increase feed consumption, body weight gain, and significantly decreased feed conversion ratio. In conclusion, J. curcas leave meal have anthelmintic activity to A. galli and could improve nutrient utilization of naturally A. galli-infected native chicken by decreasing feed conversion ratio.

This experiment was conducted to evaluate the effect of supplementation with lerak extract combined with mineral block on protozoal and bacterial population, and fermentation characteristic in vitro. The experimental design was completely randomized block design with 3 treatments and 4 replications. Control diet was a substrate that consisted of concentrate, forage and feed block with ratio 50 : 48 : 2, respectively. The treatments as a substrate were: control diet (C), C + 0.09% lerak extract, and C + 0.18% lerak extract from the total ration. Variables observed were protozoal and bacterial population, dry matter and organic matter degradability, N-NH3 and total volatile fatty acid (VFA) concentration. Data were analyzed using analysis of variance (ANOVA). The result showed that there were no significant effect (P>0.05) for all parameter measured with lerak extract supplementation up to 0.18% in the presence of mineral block. However, supplementation of lerak extract 0.18% only slightly reduced protozoal numbers but tended to increase bacterial numbers. Dry matter and organic matter degradability and concentration of N-NH3 were similar among treatments. Volatile fatty acids profile changed which propionate tended to increase and acetate tended to decrease and ratio of acetate to propionate tended to decrease. In conclusion, addition of lerak extract up to 0.18% from total ration in the presence of mineral block was not yet effective to depress protozoal population, but could modify fermentation characteristic in vitro.
