Detection of Cows with So Poor Prognosis as to Require Emergency Slaughter

Abstract

Analysis was made on sick cows in which so poor prognosis had been made as to require emergency slaughter from the results of the blood test for screening. The deta used for it were collected from 14 items of the blood test on 25 healthy cows and 24 sick cows in which so poor prognosis had been made as to require emergency slaughter. The methods used were cluster analysis, principal component analysis, discriminast analysis, and analysis of variance.The results of analysis indicated that prognosis was poor when Ca, Eo, iP, and Mg were low in level and Fib, Glu, GOT, LDH, and T.Bil high in level. It was suggested that it might be necessary for sick cows to be subjected to emergency slaughter when Fib exceeded 1, 200mg/dl, Glu 100mg/dl, GOT 200 KU, LDH 500 WIU, and T.Bil 0.8mg/dl in the cows.
