Abstract

Wheat pollard is a common feed ingredient, but its non starch polysaccharide component is still a limiting factor as an anti nutrition. The combination treatment of enzymes from rumen liquor (DE) and steam pelleting (SP), could change non-starch polysaccharide structure to be more digestible for broiler chicken. Twenty seven broiler chicken of 37 days old were divided into 27 experimental unit and randomly offered one of 9 treatments, that were R1 (DE 0 U/kg + 600C), R2 (DE 0 U/kg + 800C), R3 (DE 0 U/kg + 1000C), R4 (DE 620 U/kg + 600C), R5 (DE 620 U/kg + 800C), R6 (DE 620 U/kg + 1000C), R7 (DE 1.240 U/kg + 600C), R8 (DE 1.240 U/kg + 800C) and R9 (DE 1.240 U/kg + 1000C). The chicken have been fasted for 24 hours and fed by force feeding 30 g/head while water was offered ad libitum. Apparent Metabolizable Energy (AME), Nitrogen Corrected Apparent Metabolizable Energy (AMEn), True Metabolizable Energy (TME), Nitrogen Corrected True Metabolizable Energy (TMEn) and Nitrogen Retention were determined. Three chickens were used for collecting nitrogen and endogenous energy. Data were analyzed by analysis of variance according to completely randomized design with factorial 3x3 and Duncan’s Multiple Range Test. Enzymes dosage and steam treatment did not influence metabolizable energy (AME, AMEn, TME and TMEn) and nitrogen retention. Combination of enzymes (R4 and R8) and steam temperature treatment increased AME, AMEn, TME and TMEn but did not increase nitrogen retention. The result indicated that combination of enzymes at dosage of 620 U/kg with steam 600C treatment increased the metabolizable energy of wheat pollard based diets.

Abstract

Cholin (B-hydroxyethyl-trimethylammonium hydroxide) is a constituent of phospholipids, can interfere the metabolism process that affects the growth. Sometimes cholin in a diet does not meet the animal requirement because of its low availability. The objective of the research was to study the effect of cholin chloride supplementation in the diets on broiler performance. A completely randomized design with 4 treatments and 4 replications were used in the experiment on broiler chicks reared up to 6 weeks of age. The treatment diets were R1 (control), R2 (R1 + 750 mg cholin chloride/kg diet), R3 (R1+ 1,500 mg cholin chloride/kg diet), R4 (R1+ 2,250 mg cholin chloride/kg diet). All of the prestarter diets (0-2 weeks of age) contained isocaloric (3,000 kcal ME/kg) and isoprotein (24.8% crude protein). The starter-finisher diet (2-6 weeks of age) contained 3,000 kcal ME/kg and 20% crude protein. Supplementation of 750 mg cholin chloride/kg diet (R2) increased (P < 0.01) body weight gain and final body weight. Supplementation of 1,500 mg cholin chloride/kg diet (R3) and 2,250 mg cholin chloride/kg diet decreased (P < 0.01) body weight gain, final body weight, as well as feed efficiency. It was concluded that supplementation of 750 mg cholin chloride/kg diet (containing 1,956 mg cholin/kg in prestarter diet and 1,791.3 mg cholin/kg in starter-finisher diet) yielded the best performance of the broilers. Key words : cholin chloride, broiler chickens, performance

Abstract

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

Abstract

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

Abstract

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.

Abstract

Jatropha curcas meal (JCM) contains high crude protein (58%-60%), but it can not be used properly because of anti-nutritional contents known as curcin and phorbolesther. These components interferes protein metabolism and body protein synthesis. This study was conducted to evaluate the effect of feeding fermented JCM using Rhizopus oligosporus on broilers' performances. Ninety six of day old chicks  of Ross strain broiler (initial body weight 45.6±1.7 g) were used and reared for five weeks. The treatments were: R0 (diet without JCM), R1 (diet contained 3% fermented JCM), R2 (diet contained 6% fermented JCM) and R3 (diet contained 9% fermented JCM). A completely randomize design with 4 treatments and 4 replications was assigned in this experiment. The data were analyzed using analysis of variance (ANOVA). The results indicated that feeding fermented JCM at the level of 3% to 9% in starter and grower-finisher broilers highly significant reduced (PR. oligosporus indicated no effective detoxification process in relation to the improvement of broiler performances.
