Pengaruh oksitetrasiklin dan amoksisilin sebagai aditif pakan terhadap performan, residu dalam jaringan dan ekstra broiler=The effect of oxytetracycline and amoxycilin as feed additive on performance tissue and excreta

ABSTRAK This experiment was conducted to study the effects of level, feeding times, oxytetracyline and amoxycilin on performance, tissue and excreta residues of broilers. The experiment used the randomized completely block design with factorial 2x3x3, consisted of 2 kinds of antibiotics, i.e., oxytetracycline (Ao) and amoxycillin (Aa)3 levels of controls (Lo), 50 ppm (L^) and 100 ppm (L]00)and 3 different feeding times, i.e., 0-3 weeks (W^, 3-6 weeks (W2) and 0-6 weeks (W3). Every treatment was repeated four times with 4 chickens each, where as the determination of antibiotics\u27 residue was repeated three times. The data were analysed with variance analysis by the randomized completely block design with factorial and Duncanis test. The experiment results showed that there were no significant effects of antibiotics and feeding times on the performance. Feeding level affected (
