This article is from PLoS ONE, volume 8.AbstractPurpose: The mechanism underlying the decline in milk quality during periods of feeding high-concentrate diets to dairy ruminants is not well documented. The aim of this study was to investigate the metabolic changes in the liver that contribute to the input of substrate precursors to the mammary gland after feeding a high-concentrate diet to lactating goats for a long period. Experimental Design: Eight mid-lactating goats with rumen cannulas were randomly assigned to two groups. For 9 weeks, the treatment group was fed a high-concentrate diet 60% concentrate of dry matter, HC and the control group was fed a low-concentrate diet 40% concentrate of dry matter, LC. Ruminal fluid, plasma, and liver tissues were sampled, microarray techniques and real-time polymerase chain reaction were used to evaluate metabolic parameters and gene expression in liver. Results: Feeding a 60%-concentrate diet for 9 weeks resulted in a significant decrease in rumen pH. Changes in fat and protein content also occurred, which negatively affected milk quality. Plasma levels of leptin p = 0.058, non-esterified fatty acid p = 0.071, and glucose p = 0.014 increased markedly in HC group. Plasma cortisol concentration was significantly elevated in the treatment group p
