Abstract

The present invention relates to a dairy cow sub-clinical ketosis diagnosis test paper which belongs to the art of the veterinary clinical laboratory science. The present invention comprises a support cushion and a test cushion that is fixed on the support cushion; and the present invention is characterized in that the test cushion of the test paper comprises the following reagents: D-(-)-3-Hydroxybutyrate Dehydrogenase with 2270U/mg and 50mg-100mg; nicotinamide adenine dinucleotide with 300mg-500mg; diaphorase with 35U/mg-45U/mg and 500-1,000mg; NBT with 100mg-200mg; Tris Base with molecular weight 121.14 and 1.21g; oxalic acid with molecular 126 and 126mg; fucose with molecular 383 and 4-6g; and distilled water with 100ml. The dairy cow sub-clinical ketosis diagnosis test paper of the present invention is used conveniently and has the advantages of economic practicality, high sensitivity and specificity, and good stability. The test paper is used to test D-(-)-3-Hydroxybutyrate and D-(-)-3-Hydroxybutyrate sodium in the milk of the milch cow.

Description

technical field [0001] The invention belongs to the field of veterinary clinical laboratory science, and the detected substance is D-(-)-3-hydroxybutyric acid and its salt in cow milk, which is suitable for monitoring subclinical ketosis of dairy cows in intensive dairy farms. Background technique [0002] Ketone bodies are the products of fatty acid metabolism, and the production of ketone bodies reflects the intensity of fat oxidation metabolism. Under normal circumstances, the concentration of ketone bodies in the blood is relatively constant, because the ketone bodies produced in the liver can be quickly utilized in extrahepatic tissues, especially the kidney and myocardium have a strong enzyme system that oxidizes acetoacetate, followed by the brain. Muscle tissue is also an important tissue for utilizing ketone bodies. The use of ketone bodies as an energy source is of great significance for brain tissue that cannot utilize fatty acids. However, under certain physiol...
