An Investigation on Body Condition Score, Body Weight, Calf Weight and Hematological Profile in Crossbred Dairy Cows Suffering from Dystocia
Özet
The knowledge of hematological values is useful in diagnosing various
pathological and metabolic disorders, which can adversely affect
reproductive performance of cows. The aim of this study was to
investigate body condition score (BCS), body weight, calf weight, blood
erythrocyte parameters and total and differential leukocyte count
changes in dystocia-affected crossbred dairy cows. Values of mean
corpuscular volume (MCV) and neutrophil count were markedly increased
(P<0.001) in the dystocia group compared to normal calving group. The
levels of mean corpuscular haemoglobin concentration (MCHC) and
hematocrit in dystocia-affected cows were significantly lower (P<0.001)
than normal control group. However, in cow suffering from dystocia,
counts of the white blood cells (WBC), red blood cells (RBC),
haemoglobin concentration, mean corpuscular haemoglobin (MCH),
eosinophils, basophils, lymphocytes and monocytes were not different
from the normal parturient group. In cows with dystocia, BCS, age and
parity of dams did not show significant difference compared to normal
parturition. However, body weight in cows with difficult calving was
lower (P<0.05) than spontaneous calving cows. These results suggest that
hematocrit, MCV, MCHC and neutrophil counts were significantly affected
due to dystocia in cattle. BCS, age and parity of the cow had no affect
on the occurrence of dystocia. (C) 2011 PVJ. All rights reserved
