Judul: The Influence of Supplementation Antanan (Centella asiatica (L.)Urban) and Feather Meal in Diets to Performance of Chicken Broiler Experiencing of High Ambient Temperature.
Abstrak: This experiment was conducted to study the influence of antanan (Centella Asiatica (L.) Urban) and feather meal in diet on performance of broiler exposed to high ambient temperature. This research was run on August to September 2002 in climatic chamber (temperature range from 27.73 to 31.84°C), Biochemical, Physiology and Microbiological Nutrition Laboratory by using 81 chicken broiler strain Avian from age of two weeks and reared for four weeks. Experimental diets were formulated iso-nitrogen and iso-calori containing crude protein 21% and metabolizable energy 3200 KcaUkg. This experiment used Complete Randomized Design (RAL) with two Factorial Pattern of 3 x 3 with three replications. Each of replication consisted of three chickens. Antanan as first factor (factor A) consisted of three levels i.e.: 0%, 5% and 10% and feather meal as second factor (factor B) consisted of three levels i.e.: 0%; 4.8% and 9.6%. Data obtained were analyzed using ANOVA (Analysis of Variance). When the results were significant, the data analyzed continued using Test of Contrast of Orthogonal to see the difference among the treatments. Parameters measured were Feed intake, body weight gain, feed conversion ratio (FCR), mortality and income over feed and chick cost (IOFCC). The results showed that there is no interaction between antanan and feather meal on consumption of diets and accretion of body weight gain of chicken under heat stress, whereas conversion of diets showed a significant interaction (P<0.05). The use of antanan up to 10% and feather meal up to 4.8% in the diet did not have any effect on consumption and accretion ofhody weight gain. In contrast, The use of feather meal up to 9.6% significantly (P<0.01) decreased feed consumption and accretion ofhody weight gain. The use of 5% antanan and 4.8% feather meal in the ration resulted in the best response in term of economic value. Keyword: high ambient temperature, performance, antanan, feather meal.

Judul: Performa dan Analisis Ekonomi Broiler yang Diberi Ransum Sumber Pati atau Lemak Tinggi sebagai Sumber Energi serta Suplementasi Vitamin E dan C
Abstrak: Environmental temperature in Indonesia is high enough to let heat stress in broiler chicken. This heat stress may cause oxidative stress, decrease feed consumption and production. Vitamin E and C are usually used as anti heat-stress agent while carbohydrate and lipid are used as energy source. The purpose of this research was to find out the influence of supplementation of vitamin E and C through drinking water on broiler performance fed carbohydrate or lipid as energy source. The dose of vitamin E and C given was 1 g/L drinking water. This research used 160 Ross broiler chickens. This study used Completely Randomized Design (CRD) with four treatments (R1: carbohydrate based diet, R2: lipid based diet, R3: R1+ vitamin E and C supplementation, and R4: R2+vitamin E and C supplementation) and four replications. The data were analyzed using ANOVA. Variables measured were feed consumption, final body weight, body weight gain, feed conversion, mortality, and income over feed and chick cost (IOFCC). The results indicated that carbohydrate or lipid based diet and supplementation of vitamin E and C did not influence the feed consumption, final body weight, body weight gain, and mortality. However the lipid based diet supplemented with vitamin E and C improved feed efficiency. The feed conversion of R4 was 1.46. The IOFCC of R4 was the highest. The conclusion of this research was lipid based diet supplemented with vitamin E and C resulted the best performances and had the highest profit.
