Abstract
The aim of this study was to evaluate the effect of different levels of threonine (0.81, 0.86, 0.91%) and lysine (1.10, 1.16, 1.24%) supplementation to the diet on feed intake, body weight gain and feed conversion ratio of male broiler chicks and to evaluate threonine aminoacid requirements of chicks. Day old, seventy five Ross 308 male chicks were divided into five dietary treatment groups; chicks were placed in individual cages. In the experiment, threonine and lysine supplementation to the diet affected feed intake, body weight gain and feed conversion ratio statistically (P<0.05), threonine+lysine supplementation to the diet improved feed consumption and body weight gain but did not improved feed conversion ratio. It was found that threonine and lysine levels were lower than broiler chick’s requirements and also it was necessary to increase threonine and lysine levels in the broiler chick’s diets in the experiment.
Özet
Bu çalışmanın amacı, karma yeme farklı düzeylerde treonin (%0.81, 0.86, 0.91) ile lizin (%1.10, 1.16 ve 1.24) katkısının erkek etlik civcivlerin yem tüketimi, canlı ağırlık kazancı ile yemden yararlanma oranı üzerine etkisini saptamak, civcivlerin treonin ve lizin aminoasit gereksinmesini bulmaktır. Denemede 1 günlük 75 adet Ross 308 erkek civciv, 5 muamele grubuna dağıtılmış, civcivler bireysel kafeslere konulmuştur. Denemede yemlere treonin ile lizin ilavesi yem tüketimini, canlı ağırlık artışı ve yemden yararlanma oranını istatistiki olarak etkilemiş (P<0.05), treonin+lizin katkısı grupların yem tüketimi ile canlı ağırlık kazancını artırmış, yemden yararlanma oranını ise kötüleştirmiştir. Denemede treonin ve lizin düzeylerinin, hayvanların gereksinmelerinin çok altında kaldığı, etlik civciv yemlerindeki treonin ve lizin düzeylerinin artırılmasının gerekli olduğu da saptanmıştır.
