STUDY ON NUTRITIONAL STATUS OF COW AROUND PERIPARTURIENT PERIOD OF CROSS BREED IN COMMERCIAL DAIRY FARM

Abstract

The present study was carried out to investigate the nutritional status of cow around periparturient period. For this, a six month long study was conducted in Paharika Farm Limited, Fatikchari, Chittagong. A questionnaire survey was used to know the actual number of cattle which will deliver within one month of start of this study. Blood samples were collected aseptically from Jugular vein of these cows (n=24) and tagged properly. These cows were monitored for three months and blood samples were taken again within seven days after parturition and two month after parturition from tagged cattle. After clotting, obtained serum samples were further centrifuged to get clean serum and stored in eppendorf tube giving unique identification number and preserved in -200C until analysis. Serum samples were analyzed in Research laboratory of Department of Physiology, Biochemistry and Pharmacology, Chittagong Veterinary and Animal Sciences University for carbohydrate and protein (Glucose and Total protein, Albumin), lipid profile (Triglycerides, Cholesterol, High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL)), mineral profile (Calcium, Magnesium and Phosphorus) using automated biochemical analyzer (Humalizer®-3000, Germany). We found no significant variation in Glucose and Total protein level though Albumin level differed significantly (p < 0.001) in three different stages of periparturient period. Significant increase (p<0.01) of all the parameters of lipid profile was found in cattle after two months of parturition and significant lower level of these lipid profile in cattle before one month of parturition. The result also represented significant variations in the estimated mineral (Ca, Mg, P) level in the three different stages of periparturient period. This study suggests further intensive study to validate this finding of different biochemical parameters.
