Abstract: | To obtain blood biochemical basic data of Japanese Black calves in Kagoshima Prefecture, Japan, blood samples
were obtained from 582 clinically healthy calves on 27 farms. Calves were divided into three stages: the
suckling stage (between 14 and 90 days of age, n=191), the early growing stage (between 91 and 180 days of
age, n=200) and the late growing stage (between 181 and 270 days of age, n=191). The mean concentration of
total cholesterol, triglyceride, nonesterified fatty acids, calcium and zinc, and the mean activities of
γ-glutamyltransferase and alkaine phospatase in the suckling stage were significantly higher than those in the
early and late growing stages (P<0.01). The mean concentration of total protein, albumin
and globulin increased gradually with growing. The mean concentration of beta-hydroxybutyrate in the suckling
stage was below 150 µmol/l, however, it elevated above 400
µmol/l in the early and late growing stages. The mean concentration of
copper concentration was above 70 µg/dl in all stages. The mean
concentration of zinc was between 90 and 110 µg/dl in all stages. These
results suggest that the blood biochemical values of Japanese Black calves vary with growing stages, and the
blood parameters obtained in this study are considered useful as indices for health management of Japanese
Black calves. |
