Özet: Günümüzde hayvanlardan vücut ölçüleri alabileceğimiz güvenilirlik ve fiyatı farklı pek çok teknoloji vardır. Bunlardan Bilgisayarlı Tomografi (BT), ilk olarak tıpta tanı için kullanılmış ve son 20-30 yıldan bu yana ise çiftlik hayvanlarında karkas kalitesinin belirlenmesi çalışmalarına başarılı bir şekilde uyarlanmıştır. Elde edilen verilerin seleksiyon indekslerinde kullanılmasıyla da daha yüksek genetik ilerleme sağlanmıştır. BT ile canlı hayvanlardan karkas ağırlığı, yağ, kas ve kemik miktarları, karkas randımanı, yağ oranları, but, bel ve göğüs bölgelerinde kas yüzdesi ile göz kası uzunluğu, derinliği ve genişliği ölçülebilmektedir. Günümüzde BT teknolojisi başta İngiltere ve Yeni Zelanda olmak üzere birçok ülkede et koyunculuğunda, et sığırcılığında, domuz, kanatlı hayvan ve balık yetiştiriciliğinde başarılı bir şekilde kullanılmaktadır. Bununla birlikte bu yöntemin pahalı olması ve belirli cihazlara ihtiyaç duyulması gibi dezavantajları vardır. Bu derlemede canlı hayvanların vücut kompozisyonlarının belirlenmesi ve karkas kalitesinin iyileştirilmesinde BT teknolojisinden yararlanma olanakları değerlendirilmiştir.

Using X-ray Computed Tomography Measurements to Predict Body Composition and Carcass Quality of Live Animals
Summary: There are many technologies available to measure body composition and they differ in accuracy, reliability and cost, at the present time. For example, computer technology (CT), originally used in diagnostic medicine for humans, have been adapted in the last 20-30 years for using determination of carcass quality study in farm animal species with considerable success. The data from live animal using computer technology for index selection also obtained high genetic gain per generation. This scope, using by CT in live animals can be measured total carcass weight, amount of fat, muscle, and bone, rate of carcass fat, muscle and bone, carcass yield, percentage of shoulder, back and chest muscles of parts of the eye muscle length and depth. More recently, especially the United Kingdom and New Zealand in some countries, including, the use of CT in carcasses has been used to successfully in pigs, sheep, beef cattle, poultry and fish breeding. Nevertheless, these methods are expensive and need specific equipment. In this review, using CT technology opportunities was assessed to determine improving body composition and carcass quality of live animals.
