Abstract :ÖZET Civciv rasyonlarında 8 hafta süreyle, çeşitli düzeylerde (0.00, '25,50,100 mg/kg yem) ampicilin, terramycin, ç. bacitracin, erythromycin ve bakın sülfatın; tavuk rasyonlarında ise 6 aylık periyotta, farklı düzeylerdeki (0.00, 25; 50,100 mg/kg yem) terramycin ve çinko bacitroc'ın'in etkileri araştırılmıştır. Sekiz haftalık periyotda, kontrol grubuna nazaran ampicîllin, çinko bacitracin, terramycin, erythromycin ve bakır sülfath rasyonlarla beslenen gruplarda canlı ağırlık artışı sırasıyla % 658, % 7.38, % 9.7, % 857 ve % 5.3 nisbetlerde daha yüksek olmuştur. Antibiyotikler ve bakır sülfatın civcivlerin yemden yararlanma ve yaşama gücüne etkileri farklı olmamıştır. Yumurta tavuklarında terramycin ve çinko bacitracin'in tavukların yumurta verimi, yumurta ağırlığı, yemden yararlanma ve yaşama gücüne etkileri istatistiki olarak Önemli bulunmamıştır. Fakat antibiotik olan gruplarla yumurta ağırlığı, basal rasyonla beslenen grubunkinden önemli derecede düşük bulunmuştur, THE EFFECTS OF DIFFERENT ANTIBIOTICS ON THE VARIOUS PERFORMANCES OF THE LAYING HENS AND BROILER CIIICKS SUMMARY Two exp erime nt were conducted in order to de ter mi ne the effects of verious levels of ampicillin, terramycin, batcitracin, erythromycin and copper sulphate in broiler chiks; the effects of terramycin and zine bacitracin in layin hens. Only one control groupped factorlal experimental design of dectary treatments at four levels (0, 00, 25, 50, 100 mg/kg feed) of supplementary ampicillin, terramycin, zince bacitracin, erythromycin and cupper sulphate were studied in the fırst eıperiment. Day-old 14 male andfemale chick were randomly assigned to each of the dictory treatments The second experiment was rum with 22-weeks oldpulletsfor 6 months. Two replicated of 15 white leghorn pullets were randomyl assigned to diets containing various levels (O, 00, 25,50,100 mg/kgfeed) ofZine bacitracin and terramycin. İn the flrst experiment (or in broiler chicks) there were no significant dijferences among the dietary treatments containing supplementary antibiotics and Cu-sulfate in regarding to eight-\veek body weight, feed effıcienty and the survival rate. But the chicks receiving ampicillin, zinc bacitracin, terramycin, erythromycin and copper sulphate gained 658 %; 7.38 %; 9.70 %; 857 % and 5.30 % more body weight respectively ofthosefed basal diet. In the secont experiment (or in laying hens) the terramycin and the zinc bacitracin have no significantly effected on the egg producting, egg weight, feed efficiency and survival rate of the laying hensfor 6 mounths. But the egg weights of the groups receiving 25, 50 and 100 mg. of terramycin and zince bacitracin were significantly less than those receiving basal die
