Farklı Tahıl Kaynaklarını İçeren Broyler Rasyonlarına Butirik Asit İlavesinin Büyüme Performansı ve Bağırsak Histomorfolojisi Üzerine Etkileri

Bu çalışma mısır veya buğday/arpa temelli broyler rasyonlarına bütirik asit ilavesinin büyüme performansı ve bağırsak histomorfolojisi üzerine etkilerini araştırmak için yapılmıştır. Toplam 240 adet, bir günlük yaştaki erkek broyler civcivler (Ross-308) 2 farklı butirik asit düzeyi (%0 ve %2) ve 2 farklı tahıl grubu (mısır ve buğday/arpa) olmak üzere 2x2 faktöryel düzende 4 farklı deneme grubuna ayrılmıştır. Deneme grupları her birinde 15 adet civciv bulunanan 4 alt gruptan oluşmuştur. Deneme boyunca yem ve su ad libitum olarak sağlanmıştır. Denemenin 42. gününde sonuçlar, buğday/arpa bazlı rasyonlara bütirik asit ilavesinin canlı ağırlık, canlı ağırlık artışı ve yem tüketimini iyileştirdiğini (p<0.05) göstermiştir. Ayrıca, farklı tahıl bazlı rasyonlara bütirik asit ilavesi denemenin 1-21 günlük döneminde yemden yararlanma oranını iyileştirmiştir (p<0.001). Benzer şekilde, bütirik asit ilavesi 21 günlük yaşta jejunumda kript derinliğini önemli ölçüde etkilerken (p<0.05) villus yüksekliği buğday/arpa bazlı rasyonlarla beslenen civcivlerde daha yüksek (p<0.01) bulunmuştur. Sonuç olarak, buğday/arpa bazlı broyler rasyonlarına bütikik asit ilavesinin faydalı bir uygulama olduğu görülmüştür.

Effects of Dietary Butyric Acid Inclusion in Different Source of Grains Based Diets on Growth Performance and Intestinal Histomorphology in Broiler Chickens

This study was conducted to determine the effects of butyric acid addition in corn-based or wheat/barley-based diets on growth performance and intestinal morphology of broilers. Two hundred and forty one-day old male broiler (Ross-308) chicks were assigned to 4 treatments in 2 × 2 factorial arrangement of dietary butyric acid (0 and 0.2%) and grains (corn and wheat/barley) with 4 replicate pens in each treatment, each having 15 birds. Feed and water was provided ad libitum throughout the experiment. Results indicated that dietary butyric acid supplementation in wheat/barley based diets had improving effects on body weight, body weight gain and feed intake at day 42 of experiment (p<0.05). Moreover, the addition of butyric acid in different source of grain based diets also improved the feed conversion ratio of birds at days 1-21 of the trial (p<0.001). Similarly, crypt depth of jejunum was significantly affected dietary butyric acid inclusion in birds at 21 day of age whereas villus height was higher in birds fed wheat/barley based diets (p<0.05 and p<0.01, respectively). In conclusion, butyric acid supplementation to wheat/ barley based diets seems to be useful practice for broiler chickens.
