Assessment possible subclinical ketosis in pregnant conditions in Mehraban sheep compared to Afshari sheep

Abstract

Introduction: Subclinical ketosis is considered one of the important veterinary
diseases which causes high economic losses. negative energy balance, especially at the
late-pregnancy and lactation, can cause ketosis in the flock.
Materials & Methods: In this study, Blood samples were collected of 125 sheep,
which included 30 pregnant Mehraban sheep, 35 pregnant Afshari sheep, 30 nonpregnant
Mehraban sheep, and 30 non-pregnant Afshari sheep. The age of the sheep
was 3 to 4 years and all of them were healthy and had single birth history. Glucose,
BHBA (beta hydroxyl butyric acid), total protein, albumin, urea, creatinine,
cholesterol, triglyceride, calcium, phosphorus, magnesium, Serum aspartate
aminotransaminase and alanine transaminase activity were measured in serum by
autoanalyzer with commercial kits.
Results: Statistical analysis of the data showed that, in Mehraban breed which
pregnant compared with non-pregnant, glucose decreased significantly and BHBA,
cholesterol and triglyceride increased significantly. In Afshari breed which pregnant
compared with non-pregnant glucose and magnesium decreased significantly and
BHBA, cholesterol, triglyceride and urea increased significantly. According to the
results, both breeds had subclinical ketosis (BHBA = 0.86-1.6).
Conclusion: In this research, was seen, sub clinical ketosis changes liver enzymes,
level of serum proteins, blood lipids and kidney factors, so sub clinical ketosis can
affect on different organs in animals.
