Özet
Bu çalışma, farklı düzeylerdeki formaldehit muamelesinin soya küspesinin (SK) rumendeki kuru madde (KM), ham protein (HP), efektif kuru madde (EKMP) ve efektif protein parçalanabilirliği (EPP), ile bunlara ait parçalanma parametreleri (a, b, a+b, c) üzerine etkisini incelemek amacıyla yapılmıştır. Çalışmada SK ham protein miktarının %0, 0.3, 0.6 ve 0.9'u düzeyinde formaldehit ile muamele edilerek 2, 4, 8, 16, 24 ve 48 saatlik sürelerde nanende inkubasyona tabi tutulmuştur. Muamelesiz ve %0.3, 0.6 ve 0.9'u düzeyinde formaldehit muameleli SK'nin 48 saatlik inkubasyonda kuru madde parçalanabilirliği sırasıyla %89.38, 85.04, 77.09, 70.81 ham protein parçalanabilirliği %87.67, 79.98, 68.42, 58.61 olarak bulunmuştur (P < 0.01). Yine k=0.05 de efektif kuru madde parçalanabilirliği %58.58, 55.15, 52.38, 49.85 efektif ham protein parçalanabilirliği ise %49.48, 44.55, 39.75, 36.73 olarak tespit edilmiştir (P < 0.01). Çalışmada parçalanma parametrelerinin de (b, a+b) muamelelerden önemli derecede etkilendiği saptanmıştır (P < 0.05). SK'nin gerek kuru madde gerekse ham protein parçalanma oranlarının formaldehit muamelesi ile önemli derecede azaldığı, bu azalmanın formaldehit düzeyi ile doğru orantılı olduğu belirlenmiştir.
This study was conducted to determine the effects of different level of formaldehyde treatments on dry matter (DM), crude protein (CP), effective DM (EDMD), effective CP (ECPD) degradabilities and degradation kinetic parameters of soybean meal in the rumen. Soybean meal was treated with 0, 0.3, 0.6, and 0.9% formaldehyde and then incubated in the rumen for 2, 4, 8, 24, and 48 hours. Degradability of DM was 89.38, 85.04, 77.09, and 70.81 degradability of CP was 87.67, 79.98, 68.42, and 58.61% for soybean meal treated with 0, 0.3, 0.6, and 0.9%, respectively (P < 0.01). At the passage rate of 0.05, EDMD was 58.58, 55.15, 52.38, and 49.85% and ECPD was 49.48, 44.55, 39.75, and 36.73% for increasing level of formaldehyde respectively (P < 0.01). There were also significant effects of formaldehyde treatments on "b" and "a+b" kinetic parameters (P < 0.05). In conclusion, degradabilities of DM and CP in the rumen decreased accordingly with increased levels of formaldehyde treatment of soybean meal.
