Performa Broiler dengan Ransum Mengandung Campuran Ampas Sagu dan Ampas Tahu yang Difermentasi dengan Neurospora crassa
Media Peternakan , 2009,
Abstract: The experiment determined the effect of the mixture of sago and tofu by-products fermented with Neurospora crassa on broiler performances. One hundred of broiler chicken were randomly divided into four groups of dietary treatments and five replications (5 birds each). The experiment was arranged in a completely randomized design according to dietary treatment tested, namely, none or 0% (RA), 7% (RB), 14% (RC) and 21% (RD) fermented sago and tofu by-products mixture. Experimental diets were formulated iso-protein (22%) and iso-energy (3000 kcal/kg). Variables measured were performances, carcass quality (meat cholesterol) of broiler and income over feed chick cost (IOFCC). Results of the experiment indicated that feed consumption, body weight gain, feed conversion ratio, nitrogen retention and carcass percentage were not affected by feeding fermented sago and tofu by-products mixture. Meat cholesterol indicated the lowest but IOFCC indicated the highest of RD group treatment mixture as compared to other treatment groups. It is concluded that feeding ration containing 21% fermented sago and tofu by-products maintains broiler performance similarly to that of control group, reduce meat cholesterol by 27% and increase IOFCC by 35.41%.

Pakistan Journal of Nutrition , 2005,
Abstract: The objective of this study was to evaluate the tomato pomace (TP) as unusual feed stuff in broiler diets in terms of growth, feed conversion ratio (FCR) and mortality. 300-day old Hubbard broiler chicks were weighed and randomly distributed into 4 groups with three replicates of 25 chicks each. Birds were fed four experimental diets in which the first was the control group (T1) and the other diets contained 10% alkali treated tomato pomace (T2), 10% heat-treated tomato pomace (T3) and 10% sun dried tomato pomace (T4). All diets were isonitrogenous and isocaloric. Feed and water were offered ad-lib during the experiment period. The results of this experiment showed that there were no significant differences (P<0.05) in live body weight due to feeding chicks diets containing TP. The only significant difference (P<0.05) was observed between the control group and those fed dietary treatments. Body weight gain had nearly the same trend as live body weight. Cumulative feed consumption was significantly (P<0.05) affected by feeding TP when compared with control group. There were no significant differences (P<0.05) in FCR of chicks fed different dietary treatments when compared with those fed control diets. Mortality rate was 3% during the whole experiment period, which is insignificant.

Abstract: locomotion deficiencies in broiler production cause poor welfare and lead to change in drinking and feeding behavior with consequent loss in weight gain. this research aimed to assess locomotion deficiencies in broiler chicken by analyzing the vertical peak force on both feet during walk. a chamber was built with an inlet ramp, a horizontal walkway in the middle and an outlet ramp. in the walkway a thin mat with piezoelectric crystal sensors was placed to record the step vertical peak force of the feet while walking on the force platform. the measurement system consisted of a mat with electronic sensors and software that allowed real time recording of the forces and the processing and analysis of data. footage was taken from two digital video cameras and used for gait scoring. forty male broilers were chosen at random, grown under similar rearing conditions and farms, with age varying from 49 to 28 days (ten birds of same age) to be used in the trial. measurement consisted of inducing the bird to walk on the force platform which automatically registered the peak vertical force of the steps. results showed that the gait score increased with the weight and age of the birds. peak force asymmetry was found for each foot, independent of age or gait score. although not identified visually in the broilers, the peak vertical force values differed in both right and left feet leading to slow and uneven walking. walking deficiency was more severe in older birds.

Journal of Animal Production , 2009,
Abstract: An experiment was conducted to compare the effect of feeding medicinal weeds namely bandotan, patikan kebo and sidaguri on broiler chicken’s performance. The experiment used 100 broiler chicken 3 days of age and were kept for 5 weeks in battery cages. Each cage was 100 x 80 x 60 cm of size and consist 5 chickens. Design of this experiment was assigned to Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments were R0 (Basal ration without medicinal weed), R1 (95% basal ration + 5% bandotan (Ageratum conyzoides L)), R2 (95% basal ration + 5% patikan kebo (Euphorbia hirta L)) dan R3 (95% basal ration + 5% sidaguri (Sida cordifolia)). Ration and drinking water were ad libitum. Measured parameters were feed consumption, average daily gain and feed conversion ratio. Data were analyzed by analysis of variance (ANOVA) and the significant effects by Duncan’s multilple range test (DMRT). Results of this study showed that feeding 5% of medicinal weeds either bandotan, patikan kebo or sidaguri had similarly effect (P>0,05) on feed consumption, average daily weight gain and feed conversion ratio of broiler chicken. However, bandotan and sidaguri resulted average daily weight gain lower than patikan kebo. It is concluded that medicinal weeds bandotan, patikan kebo and sidagu could be fed to the chicken up to 5% without significant effect on broiler performance. Patikan kebo resulted better broiler performance than that of bandotan and sidaguri. (Animal Production 11(2): 103-108 (2009) Key Words: Ageratum conyzoides, Euphorbia hirta L, sida cordifolia, weeds

Abstract: Thiram a fungicide used for treating corn and for storing food grains were incorporated at 15, 30 and 60 ppm into the toxin free diet of broiler chicken for four weeks from the day of hatch. The clinical signs were reduced weight gain, lameness, abnormal bending of the tibial bones, enlarged hock joints and sternal recumbency. Grossly tibial dyschondroplasia was seen as a white opaque unmineralized cartilage plug in the tibiotarsus. Histopathologically, tibiotarsus revealed thinning of the growth plate, irregular arrangement of the proliferating layer, abnormal thickening of the transitional layer and thickened hypertrophic layer in the thiram fed groups. Changes were also seen in the liver, bile duct, kidney, heart, crop, gizzard, intestine, lymphoid organs including bursa, spleen and caecal tonsils and brain. There was no mortality at any levels of thiram tested. Results of the present study thus revealed that thiram at a level of even 15 ppm affected the health and performance of broiler chicken.

Abstract: The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, gut health and carcass characteristics of broiler chicken. Results indicated that the birds fed diets supplemented with organic acids showed significantly (p<0.05) higher body weight gains and feed conversion ratio. Maximum improvement was achieved in the group fed 3% fumaric acid in the diet. Differences in the cumulative feed consumption were non-significant (p>0.05) among all the treatment groups. Addition of organic acids in broiler diets increased the villus height in all the segments of small intestines but the differences were non-significant (p>0.05) in case of ileum. No effect (p>0.05) on carcass characteristics was observed among all treatments except for length and weight of small intestines which were significantly (p<0.05) increased in the groups fed supplemental organic acids.

Abstract: An experiment was carried out to study the haematological and biochemical changes of stunting syndrome in broiler chicken from day old ( group I) and 3 weeks (group III) of age to 8 weeks of age in two phases along with group II and group IV as control. Birds were slaughtered at 3, 5 ,7 and 8 weeks of age and the blood samples were collected and analyzed. The mean PCV, Hb, TEC values were reduced significantly (P<0.01) in stunted birds. Increased AHC, AMC and ABC values along with decreased ALC values were obtained. Significantly (P<0.01) lower serum total protein values and increased serum Amylase ALP, AST and ALT activity were observed in stunted groups ( I and III) whereas blood glucose values among the groups were not significant. The decreased haematological and biochemical parameters in the present study indicates a decrease in the absorption and digestion of protein and damage to liver and intestines in stunting syndrome of broiler chicken.

Abstract: Thiram a fungicide used for treating corn and storing food grains were incorporated at 15, 30 and 60 ppm into the toxin free diet of broiler chicken for four weeks from the day of hatch. Body weights (g) were recorded at weekly intervals. Average weekly feed consumption (g) and conversion were arrived at. The results showed that feeding thiram caused dose and time related severe depression in the body weight gain. Significant reduction in weight gain was observed from the first week in 60 ppm level and from second week in 30 ppm level. By fourth week all the thiram fed birds showed significant reduction in the weight gain.

Abstract: The goal of this study was to evalaute the meat quality of broiler chicken by defining Meat Quality Index (MQI). Meat quality is a complex trait which is consist of several meat quality indicators and affected by a series of factors. So, evaluation for the meat quality of broiler is indeed a difficult project. In this study, the coupling model of Principal Component Analysis and Linear programming techniques for Multidimensional Analysis of Preferences (PCA-LINMAP) was constructed to evaluate meat quality performance of broiler chicken and 250 chickens both cocks and hens from 5 populations (S01, S02, S03, S05, D99 developed by Dahen Poultry Breeding Company and Sichuan Animal Science Academy) were used as an application case, the eight main meat quality indicators of breast muscle and leg muscle were collected. About 4 representative indicators were selected by cluster analysis, they are crude fat, ultimate pH, muscle fibre number and drip loss. And then the meat quality index was constructed by PCA-LINMAP coupling model, the results show that the meat quality of S01 is the best, S03 came next, D99 came last and meat quality of female is superior to the cock in each line. Finally, the value range of MQI was identified based on its property. The PCA-LINMAP model made the evaluation for meat quality easily and the all main meat quality indicators were gathered to one integrated trait which could be contained in the breeding plan with other traits such as production and reproduction traits of broiler.
