PENGARUH PEMAPARAN DELTAMETHRIN TERHADAP BERAT BADAN DAN FEED CONVERSION RATIO PADA AYAM BROILER

Abstract

Deltamethrin is a type-II pyrethroid insecticide that is widely used in Indonesia. This insecticide is effective against insects via direact contact and ingestion. The aim of this research was to determine the effects of deltamethrin on the body weight and Feed Conversion Ratio of broiler. The total number of ten broilers was divided into two groups of five. Group I as a control group, were given standard feed and water. Group II as the experimental group were given standard feed and water containing 20 mg/L of deltamethrin. The feed consumption was weighed daily until the 35th day while the body weight of chickens was weighed weekly until the 5th week. FCR was calculated by dividing the total feed consumption with the body weight gain. The body weight gain of each group was analyzed by using Friedman test. Mann- Whitney test was used in analyzing the difference in body weight gain and FCR between both groups. The result showed that the body weight of the control group increased significantly from 119 ± 2,12g in the first week to 2546 ± 93,70g in the fifth week (P<0.05). The body weight of experimental group increased significantly from 112.4 ± 4.51g in the first week to 2036 ± 271.07g in the fifth week (P<0.05). The mean of Feed Conversion Ratio of the control group was 1,69 ± 0,07g, while for the experimental group was 1,95 ± 0,23g. The result of Mann-Whitney test showed that there was no significant difference between both groups. Based on the result, it can be concluded that deltamethrin has no effect on Feed Conversion Ratio, however, can reduce the weight gain of broilers
