Rasyona Treonin İlavesinin Büyüyen Bıldırcınların Büyüme Performansı, Karkas Özellikleri ve Serum Parametrelerine Etkisi

Bu çalışma farklı seviyelerde treonin içeren büyütme rasyonlarının büyüyen Japon bıldırcınların performans, karkas özellikleri ve serum biyokimyasal parametrelerine etkisini belirlemek amacıyla yürütülmüştür. Çalışmada günlük yaşta toplam 240 adet karışık cinsiyetteki bıldırcın civcivi 4 tekerrürlü 6 muamele grubuna rastgele dağıtılmıştır. Muamele rasyonları %0,84 (L-treonin ilavesiz), 1,02 (kontrol), 1,10, 1,20, 1,30 ve 1,40 seviyelerinde treonin içerecek şekilde hazırlanmış ve altı hafta süre ile bıldırcınlara bu muamele rasyonları verilmiştir. Rasyon treonin seviyesi bıldırcınların performans ve karkas parametrelerini istatistiki olarak etkilememiş, ancak en iyi yem değerlendirme %1,10 treonin seviyesinde elde edilmiştir. Serum kolesterol, toplam protein, albümin, kreatinin, kalsiyum ve AST seviyeleri rasyon treonin seviyesinden etkilenmezken, serum glukoz, trigliserit, globülin, üre ve fosfor seviyeleri istatistiki olarak etkilenmiştir. Rasyonun %1,30 seviyesinde treonin içermesi ile serum glukoz ve trigliserit seviyeleri minimum olurken, serum globülin seviyesi maksimum olmuştur. Serum fosfor seviyesi rasyonda %1,40 treonin seviyesinde kontrol grubuna göre önemli derecede artmıştır. Bu sonuçlara göre, %1,10 seviyesinde treonin seviyesinin büyüyen bıldırcın rasyonları için uygun olacağı söylenebilir

Effect of Dietary Threonine Addition on Growth Performance, Carcass Characteristics and Serum Parameters in Growing Quails

This research was carried out to determine the effects of diets containing different levels of threonine on the performance, carcass characteristics, and serum biochemical parameters of growing Japanese quails. In the study, a total of 240 mixed sex quail chicks at the age of one day were randomly allocated to 6 treatment groups with 4 subgroups. Experimental diets were prepared to contain threonine at 0.84 (without L-threonine addition), 1.02 (control), 1.10, 1.20, 1.30 and 1.40% levels, and quails were fed with these treatment diets for six weeks. The threonine level of the diet did not statistically affect the performance and carcass parameters of quails, but the best feed efficiency was obtained at 1.10% threonine level. While serum cholesterol, total protein, albumin, creatinine, calcium and AST levels were not affected by dietary threonine level, serum glucose, triglyceride, globulin, urea, and phosphorus levels were statistically affected. With 1.30% threonine in the diet, serum glucose and triglyceride levels were minimum, while serum globulin level was maximum. Serum phosphorus level considerably increased at 1.40% threonine level compared to the control group. According to these results, it can be said that the addition of 1.10% threonine to diet would be proper for growing quails
