In this study, broiler diet was supplemented with 0
(control), 0.3 and 0.6% and dry yeast (Saccharomyces
cerevisiae) and their effects on growth performance body weight, and feed
conversion ratio in broiler chicken were investigated weekly. One day old Ross
308 broiler chicks were divided into nine groups (40 birds for each group)
randomly. The first three groups were fed on diet supplemented with 0.3% dry
yeast. Second groups were fed on diet supplemented with 0.6% dry yeast and
other there groups were used as control. Groups were separated by knitted fence
and floored area was formed 4 square meters. Four different type commercial
diets (starter, grower, broiler and finisher) were used in the experiment.
Feeds weighed (10 kg) separately and spread on polyethylene with 2-3 cm in
thickness. Measured 30 g and 60 g dried yeast was added on the feed and mixed.
At the end of the experiment, there was no significant difference between body
weight of the groups (P> 0.05). At the end of 6 weeks, final live weights in
control, 0.3% and 0.6% dry yeast supplemented groups were 2597.7, 2654.9 and
2568.4 g, respectively. There was no significant difference between the groups
in terms of feed conversion ratio (P> 0.05). At the end of 6 weeks, the feed
conversion rates in the control, 0.3% and 0.6% dry yeast supplemented groups
were 1.64, 1.69 and 1.68, respectively. It can be concluded that dietary
supplementation of dry yeast did not change growth performance in broiler
chicks.
Bu
çalışmada, yemlerine sırası ile % 0 (kontrol), 0.3 ve 0.6 oranlarında kuru maya
(Saccharomyces cerevisiae) ilave
edilen etlik piliçlerin (broyler) büyüme performansları araştırılmış, haftalara
göre canlı ağırlıkları ve yem dönüşüm oranları incelenmiştir. Denemede her grup
3 tekerrür ve 4m2 her tekerrüre 40 adet karışık cinsiyette Ross308
etlik civciv konulmuştur. Denemede standart 4 çeşit ticari yem (başlangıç,
büyütme, etlik piliç ve bitirme) kullanılmıştır. Deneme sonunda, haftalara göre
canlı ağırlık bakımından gruplar arasında istatistikî olarak bir fark
görülmemiştir (P>0.05). 6. hafta
sonunda kontrol, % 0.3 ve
% 0.6 kuru maya gruplarındaki canlı ağırlıklar sırası ile 2597.7, 2654.9 ve 2568.4 g olarak bulunmuştur. Yem dönüşüm oranı (FCR) bakımından da gruplar
arasında istatistikî bir fark bulunmamıştır (P>0.05). 6. hafta sonunda kontrol, % 0.3 ve % 0.6 kuru maya
gruplarındaki yem dönüşüm oranları sırası ile 1.64, 1.69 ve 1.68 olarak
bulunmuştur. Sonuç
olarak, etlik piliç yemlerine farklı oranlarda ilave edilen kuru mayanın canlı
ağırlık kazancı ve yem dönüşüm oranına etkisinin olmadığı belirlenmiştir.
