Studies On The Relations Between Lipid Metabolism And Some Bio-chemical Indexes In Blood Of Cow During Perinatal Period

In order to make clear the relations in the incidence of two diseases of ketosis and the fat liver, The experiment selected 105 cows during perinatal period in huhhot region . The ultraviolet spectrophotometry was used to determine the content of glucose, glutamic-oxal(o)acetic transaminase(GOT),free fatty acid, bilirubin, glutamic-pyruvic transaminase(GPT), triglyceride, cholesterol, alkaline phosphatase,total protein, albumin, urea nitrogen in blood of normal or off-normal cows.The atomic absorption spectrophotometry was used to determined the content of cobalt (Co), manganese(Mn),magnesium(Mg) in blood. In order to find a agent of rapidly detecting ketosis, the gradient dilution method was used to detect ketone body in milk.The conclusion is the incidence of fat liver is 42.9%, the incidence of ketosis is 18.1%, the ratio of the amount of cows suffering from negative fat liver to total amount of cows suffering fat liver is 24.4%.The result also exhibits there are more or less the liver cells in fat of cows suffering from ketosis during perinatal period, but it is not sure that there is ketone body in blood of cows suffering from fat liver disease .The result exhibits the content of glucose in blood of cows suffering from fat liver is significantly lower than the content of glucose in blood of normal cows( P<0.01). The content of glutamic-oxal(o)acetic transaminase(GOT),free fatty acid,bilirubin, glutamicpyruvic transaminase(GPT) and triglyceride in blood of cows suffering from fat liver is significantly higher than those content in blood of control cows( P<0.01). The content of cholesterol, alkaline phosphatase, total protein and albumin in blood of cows suffering from fat liver is significantly lower than those content in blood of control cows( P<0.01),but the content of urea nitrogen in blood of cows suffering from fat liver did not significantly change. the content of Mg and Mn in the blood of cows suffering from fat liver is significantly lower than that of control cows( P<0.01). The content of glucose, total protein, albumin , cholesterol and alkaline phosphatase in blood of cows suffering from ketosis is significantly lower than those content in blood of control cows( P<0.01). The content of glutamic-oxal(o) acetic transaminase(GOT),free fatty acid, glutamic-pyruvic transaminase(GPT),bilirubin and triglyceride in blood of cows suffering...
