Özet
Bu araştırma, farklı seviyelerde ham protein (HP) ve metabolik enerji (ME) içeren rasyonların kapalı şartlar altında yetiştirilen etlik kınalı kekliklerin performans, karkas karakterleri ve bazı kan parametrelerine etkilerini tespit etmek amacıyla yapılmıştır. Denemede iki tip rasyon kullanılmış olup, keklikler 0-8 haftalar arasında 4 farklı HP (HP1 %16, HP2 %20, HP3 %24, HP4 %28) ve ME (ME1 2600, ME2 2800, ME3 3000, ME4 3200 Kcal/kg) ihtiva eden başlatma, 9-16 haftalar arasında 4 farklı HP (HP1 %15, HP2 %17.5, HP3 %20, HP4 %22.5) ve ME (ME1 2850, ME2 3000, ME3 3150, ME4 3300 Kcal/kg) içeren büyütme rasyonlarıyla yenilenmişlerdir. Araştırma,Tesadüf Parselleri Deneme Tertibinde Faktöriyel Düzende, 3 tekerrürlü olarak yürütülmüş ve her alt gruba karışık cinsiyette 10 hayvan konulmuştur. Keklikler, 8 haftalık yaşa kadar ana makinalarında, 9-16 haftalar arasında büyütme kafeslerinde banndınlmışlardır. Yem ve su ad libitum verilmiş, sürekli aydınlatma yapılmıştır. Başlatma periyodunda, %16 HP içeren rasyonla yemlenen grubun canlı ağırlığı (CA) ve canlı ağırlık artışı (CAA), diğer graplarınkinden önemli seviyede (P<0.01) daha düşük olmuş, ancak rasyon HP ve ME seviyelerinin grupların deneme sonu CA ve CAA'larma etkileri önemsiz bulunmuştur. Rasyon ME seviyesinin, grupların başlatma ve büyütme periyodu ile deneme sonu günlük ortalama yem tüketimine (YT) etkisi önemli olmuştur. Başlatma periyodunda, rasyon HP seviyesinin grupların YT'lerine etkisi önemsiz, büyütme periyodunda ise önemli bulunmuştur. Başlatma periyodunda, rasyon HP ve ME seviyelerinin, büyütme periyodunda rasyon HP seviyesinin deneme gruplarının yem değerlendirme katsayısına (YDK) etkisi önemli olmuştur. Rasyon ME seviyesinin, grupların deneme sonu ortalama YDK'lanna etkisi önemli, HP seviyesinin etkisi önemsiz bulunmuştur. Rasyon HP seviyesinin erkek kınalı kekliklerin karkas parametrelerinden boyun ağırlığına, rasyon ME seviyesinin karkas, but ve göğüs ağırlıklarına etkisi önemli olmuştur. Rasyon HP ve ME seviyelerinin dişi kınalı kekliklerin karkas özelliklerine etkisi önemli bulunmamıştır. Rasyon HP seviyesinin erkek kınalı kekliklerin serum kolesterol seviyene, rasyon ME seviyesinin serum kalsiyum (Ca), fosfor (P), klor (Cl) ve potasyum (K) seviyelerine etkisi önemli olmuştur. Rasyon ME seviyesinin dişi kınalı kekliklerin serum glukoz, Ca, P ve trigliserid seviyelerine etkisi önemli bulunmuş, ancak rasyon HP seviyesinin dişi kınalı kan parametrelerine etkisi önemli olmamıştır. Bu denemede, kritik amino asitlerce desteklenmek şartıyla HP seviyesi %20, ME seviyesi 2800 Kcal/kg olan başlatma ve HP seviyesi %15, ME seviyesi 3000 Kcal/kg olan büyütme rasyonlarmın kınalı keklikler için yeterli olduğu sonucuna ulaşılmıştır.
This experiment was conducted to determine effects of diets containing different levels of crude protein (CP) and metabolizable energy (ME) on the performance, carcass characteristics and some blood parameters of chukar partridge raised in captivity. Two type diets were used in the experiment. The chukar partridges were fed starter diets containing 4 levels of CP (CP1 16, CP2 20, CP3 24, CP4 28%) and 4 levels of ME (ME1 2600, ME2 2800, ME3 3000, ME4 3200 kcal/kg) from hatch to 8 weeks of age, and were also fed grower diets containing 4 levels of CP (CP1 15, CP2 17.5, CP3 20, CP4 22.5 %) and 4 levels of ME (ME1 2850, ME2 3000, ME3 3150, ME4 3300 kcal/kg) from 9 to 16 weeks of age. Sixteen treatment consisting of 4 levels of CP and 4 levels of ME in 4 x 4 factorial arrangement were used with three replicates of 10 mixsexed partridges each. The chukar partridges were kept in multideck battary brooders from hatch to 8 weeks of age, and between 9-16 weeks of age, they were raised in three-deck colony cages. Feed and water offered ad libitum, and continuous lighting was provided. Live weight and live weight gain of groups fed starter diet containing 1 6% CP were significantly (P<0.01) lower than groups fed diets containing 20, 24 and 28% CP. CP and ME levels of diets did not have a significant effect on live weight and live weight gain at 16 weeks of age. Daily mean feed consumption for starter, grower and 0-16 weeks period were affected by ME levels of diets. CP levels of starter diets did not have a significant effect on daily mean feed consumption, however, CP levels of grower diets had a significant effect on daily mean feed consumption. Average feed conversion ratio was affected by CP and ME levels of starter diets, and was affected by CP levels of grower diets. CP levels of diets did not have any significant effect on average feed conversion ratio for 0-16 weeks period, but ME levels of diets had a significant effect on average feed conversion ratio for 0-16 weeks period. CP levels of diets had a significant effect on neck weight of male partridges. The carcass, breast and rump weights of male partridges were affected by ME levels of diets. The carcass characteristics of female partridges were not affected by CP, ME levels and by their interactions. Serum calcium, phosphorus, chlorine, potassium levels of male partridges were affected by ME levels of diets. CP levels of diets had a significant effect on serum cholesterol level of male partridges. Blood parameters of female partridges were not affected by the CP levels of diets, however, ME levels of diets had a significant effect on serum triglycerides, glucose, calcium and phosphorus levels of female partridges. We concluded that when supplemented with critical amino acids, starter diets for chukar partridges raised in confinement might contain at least 20% CP, 2800 kcal/kg ME, and grower diets might contain 15% CP, 3000 kcal/kg ME.
