One hundred forty four 10-day old male Arbor Acres (320±5g) broiler chicks were used to compare the responses in liver function to dietary supplementation of milk thistle (Silybum marianum), artichoke (Cichorium intybus) and olive (Olea europaea) extracts with gemfibrozil and atorvastatin, in broiler chickens fed with a lipogenic diet. Birds raised in the standard experimental conditions and re...
