Özet
Bu çalışma, farklı düzeylerde kurutulmuş damıtma çözünürlü tanelerinin (DDGS) broylerlerde besi performansı, karkas kalitesi ve kan parametreleri üzerine etkisini belirlemek için yapılmıştır. 42 günlük deneme süresinde, 1 günlük yaştaki civcivler 4 deneme grubu ve 4 alt grup olarak ayrılmıştır (22/adet): Kontrol, grup 1 (%5 DDGS), grup 2 (%10 DDGS) ve grup 3 (%15 DDGS). Denemede 352 adet civciv kullanılmıştır. Yem ve su ad- libitum olarak sağlanmıştır. 42. günde, her gruptan 32 adet broyler (16 erkek ve 16 dişi) rastgele seçildi ve karkas veriminin belirlenmesi için kesim işlemi uygulanmıştır. Kan örnekleri her deneme grubundan 8 adet broylerden (4 erkek ve 4 dişi) alınmıştır. Deneme sonunda, farklı düzeylerde DDGS ile beslenen deneme gruplarında canlı ağırlık, canlı ağırlık artışı, yem tüketimi ve yemden yararlanma oranı bakımından farklılıklar bulunmuştur (P 0.05), taşlık ağırlığında farklılık olduğu tespit edilmiştir (P 0.05).
Abstract
The objective of this study was to investigate the effects of different levels dried distillers grains with solubles (DDGS) on growth performance, carcass quality and blood parameters in broilers. In 42 d feeding trial, 1 day old broilers were allocated to 4 experimental groups with 4 replicates (22/pen): control, treatment 1 (5% DDGS), treatment 2 (10% DDGS) and treatment 3 (15% DDGS). In experiment 352 chicks were used. Feed and water are provided ad libitum. On day 42, 32 (16 male and 16 female) chicks per treatment were randomly chosen and slaughtered for determining the carcass yield. Blood samples were taken 8 (4 male and 4 female) chicks per treatment. At the conclusion of the trial, differences in terms of body weight, body weight gain, feed intake and feed conversion ratio were found between trial groups fed DDGS in different amounts (P<0.05). As a result of the slaughtering process at the conclusion of the trial, differences (P<0.05) were found in terms of slaughter weight and cold and hot carcass weight in the trial groups. No difference was found in terms of the weight of the heart and liver (P>0.05), but gizzard weights did vary (P<0.05). Differences also emerged between the groups in terms of total protein and total triglyceride levels in the blood samples taken during the slaughtering process (P<0.05), but there was no difference between the trial groups in terms of total cholesterol levels (P>0.05).
