Performance and milk quality of the lactating dairy cow consuming ganoderma lucidum, organic chromium and CLA as feed supplement

Abstract

The aim of this study was to evaluate the use of feed supplement containing Ganoderma lucidum (GL), orgCr (organic Chromium) and CLA (Conjugated linoleic acid) from roasted soy bean by measurement of performance and milk quality of the lactating dairy cow. Two experiments were carried out in different time based on randomized block design. The first experiment used nine of the lactating dairy cow that consume three rations: R0: control; R1: R0 + GL; R2: R0 + GL + orgCr. The second experiment used twelve of the lactating dairy cow that consume four rations: P0: control; P1: P0 + GL + CLA; P2: P0 + CLA + orgCr; P3: P0 + GL + CLA + orgCr. The parameters for cow performance were consumption, average of daily gain, digestibility and milk production; while milk quality were protein, fat and total solid of milk. The first experiment results were the use of R2 increased as much two times of average of daily gain, 16% of milk production and 22% of milk fat. The second experiment results were P1 significantly increased 13% of the consumption and 18% of digestibility (P<0.05). The highest of milk production 4% FCM (9.09 kg/d) was achieved by consume P3 in which milk fat, protein and total solid significantly increased 29%, 21% and 7%, respectively from control (P<0.05). As conclusion, the performance and milk quality of the lactating dairy cow could be improved by addition of feed supplement containing Ganoderma lucidum, organic Chromium and roasted soybean as a source of CLA
