Özet
Bu çalışma mısır ve soya fasulyesi küspesine dayalı etlik piliç rasyonlarında artan valin
seviyelerinin performans, kesim ve serum parametreleri, nitrojen atılımı ve jejunum histomorfolojisi
üzerindeki etkilerini incelemek için yapılmıştır. Denemede toplam 480 adet erkek etlik civciv, her birinde
10 civciv bulunan sekiz tekerrürlü altı muamele grubuna rastgele dağıtılmıştır. Üç periyot (0-10., 11-24.
ve 25-42. günler) ile yürütülen denemede bazal rasyonlar etlik piliçler için tavsiye edilen besin madde
ihtiyaçlarına göre hazırlanmış ve valin seviyeleri %100 (V100, kontrol), %110 (V110), %120 (V120),
%130 (V130), %140 (V140) ve %150 (V150) olarak belirlenmiştir. Performans parametreleri ilk
periyotta muamelelerden etkilenmemiş (P>0.05), ikinci periyot ve deneme genelinde en iyi sonuçlar
V120 grubunda elde edilmiştir (P<0.05). Kesim özelliklerinden, but ağırlığı (P<0.05) linear olarak artmış
ve göğüs ağırlığı (P<0.01) ise azalmıştır. Serum biyokimyasal özelliklerinden glukoz (P<0.05), toplam
protein (P<0.05), globülin (P<0.01) ve kreatinin (P<0.05) linear olarak artarken, trigliserit (P<0.01)
kuadratik olarak azalmıştır. Dışkı ile nitrojen atılımı, artan diyet valini ile doğrusal olarak azalmıştır
(P<0.01). Ayrıca en yüksek villus yüksekliği V130'da ve villus yüzey alanı V120'de elde edilirken, kript
derinliği artan valinden olumsuz etkilenmiştir (P<0.01). Elde edilen sonuçlara göre en yüksek performans
ve villus yüzey alanı V120 grubunda elde edilmiştir. Yüksek seviyelerde valin uygulaması (%140 ve
%150) göğüs eti ağırlığını ve jejunum histomorfolojisini olumsuz etkilemiş ancak dışkı ile atılan nitrojen
azalmıştır. Bu sonuçlara dayanarak etlik piliç rasyonlarında valin seviyesinin tavsiye edilen seviyenin
%20'si kadar artırılabileceği söylenebilir.
Current experiment was carried out to examine the effects of increasing valine levels in broiler diets based on corn-soybean meal on performance, slaughtering and serum parameters, nitrogen excretion, and jejunum histomorphology. A total of 480 male broiler chicks were randomly allocated to six treatment groups with eight replications, each containing 10 birds. In the three-period (0-10., 11-24., and 25-42. days) experiment, basal diets were prepared according to the recommended needs of broilers and valine levels were determined as 100% (V100, control), 110% (V110), 120% (V120), 130% (V130), 140% (V140), and 150% (V150). The performance parameters were not affected in the first period (P<0.05), and best results were obtained in V120 group in the second period and cumulatively (P<0.05). Among the slaughtering characteristics, thigh ratio weight linearly increased (P<0.05) and breast weight decreased (P<0.01). The glucose (P<0.05), total protein (P<0.05), globulin (P<0.01), and creatinine (P<0.05) linearly increased, while triglyceride (P<0.01) decreased quadratically. Nitrogen excretion decreased linearly with increasing dietary valine (P<0.01). In addition, highest villus height was obtained in V130 and villus surface area was obtained in V120, while crypt depth was negatively affected by increasing valine (P<0.01). According to results, highest performance and villus surface area were obtained in V120 group. The high levels administration of valine (140 and 150%) adversely affected breast ratio and jejunum histomorphology, but nitrogen excreted with feces decreased. Therefore, valine level in broiler diets can be increased by 20% of the recommended level.
