Vital impact of using ginger roots powder as feed additive to the rations of local Friesian dairy cows and its effect on production & economic efficiency of milk and physiological of blood

Abstract

Three non pregnant local Friesian dairy cows were at same live weights, fourth production season and during first month of calving, they were divided into three treatments .2nd and 3rd treatments were reared on standard ration supplemented with 75 or 150 g. of ginger roots powder /cow /day ,respectively, while the 1st treatment reared on standard ration only. Cows were fed individually on standard ration during three periods (28 days/period) in 3x3 Latin square design. The results indicated that feed intake, daily quantities of uncorrected, corrected milk yields , fat, protein and lactose ,milk lactose %, red & white blood cell counts, hemoglobin concentration, packed cell volume ,lymphocyte %, total protein and globulin were increased significantly, while the percentages of milk fat and blood glucose were decreased significantly in T2 and T3 s as compared to those in T1.The present study was carried out to determine the effect of supplementation of ginger root on milk production and composition and physiological of blood.
