Bu çalışma 950 adet süt
sığırı  içerisinden rastgele seçilen 197
adet süt sığırı üzerinde yürütülmüştür. Hayvanlar doğum yaptıkları günden
itibaren takibe alınmış olup ilk 8 hafta boyunca kan sayımı ve serum BHBA
analizleri haftalık olarak yapılmıştır. Elde edilen BHBA sonuçlarına göre
çalışmadaki tüm hayvanlar aşağıdaki şekilde üç gruba ayrılmıştır; a) Kontrol
Grubu “K”; çalışma boyunca serum BHBA seviyesi 1.2 mmol/l’nin altında seyredenler
b) Subklinik Ketozis Grubu “SK”; serum BHBA seviyesi 1.2 ile 2.9 mmol/l
arasında seyredenler c) Klinik Ketozis Grubu “KK”; serum BHBA seviyesi 2.9
mmol/l’nin üzerinde seyredenler. Çalışmada kullanılan tüm parametreler sürü
yönetim programından (Dairy Plan, Gea, Westfalia/Almanya) alınmıştır. Çalışmada
kullanılan tüm hayvanlar aynı rasyonla beslenmiş olup hiçbir hayvana özel bir
koşul uygulanmamıştır. Yapılan analizler sonrasında TLS, LS ve NS’nın en yüksek
olduğu grup KK, en düşük olduğu grup K olarak tespit edilmiştir. Özellikle TLS
ve BHBA seviyeleri arasında güçlü bir 
ilişki tespit edilmiştir (p<0,000). Bununla birlikte hem mastitis hem
metritis hem de bu iki enfeksiyonun birlikte seyretme insidensi subklinik ve
klinik ketozis gruplarında kontrol grubuna göre çok yüksek bulunmuştur. Bununla
birlikte subklinik ve klinik ketozis geçiren hayvanlarda sürü dışı bırakma
oranı kontrol grubuna göre çok daha yüksek bulunmuş aynı zamanda ketozisin
şiddetinin artması ile bu oranının da doğru orantılı bir şekilde yükseldiği
görülmüştür. Bu bulgular göstermektedir ki gerek klinik gerekse subklinik
ketozis geçiren hayvanlarda hematolojik parametreler ciddi oranda değişmekte,
mastitis ve metritis gibi periparturient dönemin önemli enfeksiyöz
hastalıklarına yatkınlık artmakta ve tüm bunların bir sonucu olarak sürü dışı
kalma oranı yükselmektedir.

Effects of Subclinical and Clinical Ketosis on The Incidence of Mastitis, Metritis, Culling Rate and Some Hematological Parameters in Dairy Cows

Öz

The
study was conducted on 197 milk dairy cattle randomly selected from 950
breeding dairy cattle. These animals were monitored immediately after delivery
and blood count and serum BHBA analyzes were performed weekly for the first 8
weeks. According to the results of the BHBA obtained, all animals in the study
were divided into three groups as follows; a) Control Group “C”; serum BHBA
levels below 1.2 mmol/l during the study b) Subclinical Ketosis Group “SK”;
serum BHBA levels between 1.2 and 2.9 mmol/l c) Clinical Ketosis Group “CK”;
serum BHBA levels were above 2.9 mmol/l. All performance parameters such as
milk yield and reproductive efficacy obtained from the herd management program
(Dairy Plan, Gea / Germany). TLS, LS, NS, MS levels were found to be higher in the
SK and CK compared to the C. Especially, a strong positive interaction between
TLS and blood BHBA level was determined (P <0,000). In addition, the
incidence of mastitis, metritis and coexistence of these two infections was
significantly higher in the SK and CK than in the C (p <0,013). Furthermore,
the rate of culling was significantly higher in the SK and CK than C and it was
also observed that this ratio increased in parallel with the severity of the
ketosis (p <0.008). These findings show that hematologic parameters change
significantly in animals that have undergone clinical or subclinical ketosis
and that susceptibility to significant infectious diseases during the periparturient
period such as mastitis and metritis increases and as a result, the rate of
culling increases.
