Sunulan çalışmanın amacı, süt sığırlarında sırt yağ kalınlığını
inspeksiyon ve palpasyonla ( gözle ve elle) subjektif olarak ölçülen Vücut
Kondisyon Skorunu (VKS), doğum sonrası transrektal ultrasonografik muayene
yöntemi ile objektif olarak belirlemektir. İşletmedeki 350 adet süt sığırı
içerisinden rastgele seçilen ortalama 650 kg canlı ağırlıkta, 2 - 6.laktasyonda
44 adet inek kullanılmıştır. İnekler BCS göre; 1. grup (BCS ≤ 3) 22 inek
(Pelvis bölgesine yandan bakıldığında BCS’nin 3 veya 3 ‘ ün altında olduğunda
“V” şeklinin görülmesi) ve 2. grup (BCS ˃ 3) 22 inek (Pelvis bölgesine yandan
bakıldığında BCS’ nin 3’ ün üstünde olduğunda “U” şeklinin görülmesi) olmak
üzere inekler iki gruba ayrılmıştır. Derinin üstünden ultrasonografik görüntü
elde edilerek deri altı yağ kalınlığı (Subcutaneous fat thickness)
belirlenebilmekte, vücut yağ oranı ile ilgili bilgiler elde edilmektedir. Bu
çalışmada ilk kez transrektal ultrason muayene yöntemi ile ultrasonografik
görüntü elde edilmiş, sırt yağ kalınlığı tespit edilmiş ve literatüre
sunulmuştur. Transrektal ultrason muayenesinde; avuç içine alınan prob,
rektumdan içeriye sokularak, rektumun boşaltılması sağlanmış, daha sonra cavum
pelvis içinde ilerletilerek son bel omurları, sakrum ve tuber coxa’ların üst
kısımları arasında kalan sakral bölge prob ile dikey (vertically) taranarak,
kas ile deri tabakası arasındaki yağ dokusu tespit edilmiştir. Muayene sonucu
elde edilen görüntüler (corresponding images) ultrasonografi cihazına
kaydedilmiş ve bilgisayar ortamına aktarılarak değerlendirilmiştir. Araştırma
sonucunda transrektal ultrasonografi muayene yöntemine göre BCS ≤ 3 ve BCS ˃ 3
gruplarının yağ kalınlıkları tespit edilmiş ve gruplar arasında gözlenen
farklılık önemli bulunmuştur (p<0,05).

Determination of backfat thickness with transrectal ultrasonography in cattle

Öz

The purpose of this
study is to determine the Body Condition Score (BCS), which is subjectively
measured in dairy cattle with inspection and palpation of backfat thickness,
objectively by using transrectal ultrasonography examination method after
delivery. Forty-four cows, randomly selected, average 650 kg live weight, 2 - 6 lactation from 350 dairy cattle have
been used. Cows have been separated into two groups according to BCS; which are:
group 1 (n = 22) (BCS ≤ 3) and group 2 (n=22) (BCS ˃ 3). In previous studies, subcutaneous fat thickness has been determined by examining body thickness
using ultrasonographic imaging above the skin. In the transrectal ultrasound
examination; A hand-held probe was inserted from the rectum after rectum is
cleared, it was pushed forward inside the cavum pelvis, and measurements were
performed on the fat tissue between the muscle and skin layers by scanning
vertically using the probe on the sacral region between the upper parts of last
lumbar vertebrae, sacrum and tuber coxae. Corresponding images resulting from
the examination were saved on the ultrasonography device and evaluated after
being transferred in software. In the result of this study, backfat thickness of
BCS ≤ 3 and BCS ˃ 3 groups were determined according to ultrasonography
examination, and a difference was observed between groups (p < 0.05).  305- day milk yield between the groups and
TMR analysis have been determined in this study and no difference has been
determined between groups (p ˃ 0,05)
