Özet
Rasyon protein ve enerji seviyesinin Konya Merinosu kuzularında besi performansı, protein ve enerjinin kullanımına etkisini tespit etmek amacıyla 84 günlük bir çalışma yapılmıştır. Denemede ortalama canlı ağırlıkları (CA) 19.9 kg olan 2.5-3 aylık yaşta 54 baş Konya Merinosu erkek kuzu, yemlendiği şekliyle % 12.5, 15 ve 17.5 ham protein (HP) ve her bir protein seviyesinde 2250, 2500 veya 2700 kcal/kg metabolik enerji (ME) içeren rasyonlarla, tesadüf parsellerinde 3x3 faktöriyel deneme planında yenilenmiştir. Bütün kuzular ferdi bölmelerde barındırılmış, ferdi olarak tartılmış ve yenilenmişlerdir. Ana faktör olarak, rasyonda artan protein seviyesi ile birlikte canlı ağırlık artışı (CAA), günlük ham protein tüketimi (G HPT) ve enerji etkinlik oram (EEO) artarken, yem/CAA oranı ve protein etkinlik oranı (PEO) azalmıştır (P0.01). Rasyon protein seviyesi diğer performans özelliklerini önemli olarak etkilememiştir. Diğer ana faktör olan rasyon enerji seviyesi tüm performans özelliklerini önemli seviyede etkilemiştir. Rasyonda artan enerji seviyesi ile kuzuların besi sonu CA, CAA, yem tüketimi (YT), GHPT, günlük ME tüketimi (OMET), PEO ve EEO' ları artmış ve yem/CAA oranı ise azalmıştır (p0.05-p0.01). Rasyon protein x enerji seviyeleri arasındaki interaksiyonlar bu çalışmada ölçülen hiçbir özelliği önemli olarak etkilememiş ise de bütün protein seviyelerinde rasyonda artan enerji seviyesi ile birlikte CAA, GHPT, GMET, PEO ve EEO artmış ve yem/CAA oranı azalmıştır.
An 84-day experiment was conducted to determine the influence of dietary protein and energy levels on the fattening performance, utilization of protein and energy in Konya Merino lambs. In the experiment, in a 3x3 factorial arrangement in completely randomized design, 54 male Konya Merino lambs aged 2,5-3 months and at an average of 19.9 kg live weight were fed diets containing crude protein (CP) 12.5, 15 and 17.5 % with 2250, 2500 and 2700 kcal/kg metabolizable energy (ME) as fed. All lambs were penned, weighted and fed individually. As the main factor, increasing dietary protein level increased live weight gain (LWG), daily crude protein intake (DCPI) and energy efficiency ratio (EER) but, decreased protein efficiency ratio (PER) and feed/gain ratio (P<0.01). Dietary CP did not significantly alter other traits. Dietary energy level, as the other main factor, significantly effected the all performance traits. Increasing energy level of diets resulted in a significant improve in final live weight, LWG, feed intake (FI), DCPI, daily metabolizable energy intake (DMEI), PER and EER and resulted in a significant decrease feed/gain ratio (p<0.05-0.01). Although any performance traits measured in this experiment were not affected by the dietary protein x energy interaction, as the energy level in the diet increased, LWG, DCPI, DMEI, PER and EER were increased and feed/gain ratio was decreased with in the all dietary protein levels.
