GPT and fatty liver disease: In vivo, dietary rumen-protected DHA (180 g/d) supplementation reduced hepatic lipid deposition, improved liver function (evidenced by decreased total bilirubin and alanine aminotransferase), reduced oxidative stress and inflammation (suppressed malondialdehyde, glutathione peroxidase, and lipopolysaccharide), coincided with relieving insulin resistance (reduced insulin and glucose, as well increased adiponectin) in dairy cows with fatty liver.
