Abstract

The effects of a daily supplement of 300 ml fish oil and 20 g rumen-protected methionine, alone or in combination, were investigated in mid-lactation cows receiving a maize silage-based diet ad lib. Fish oil significantly decreased feed intake, increased milk yield, decreased protein and casein concentrations, and especially fat concentration (by 13·1 g/kg) and output. Fat concentration decreased more in primiparous than in multiparous cows. Methionine supplementation increased protein and casein concentrations and outputs. No significant interaction between oil and methionine supplementation was found on milk composition. Treatments did not modify live weight or body condition changes, or lactose and non-casein nitrogenous compounds in milk. Oil plus methionine supplementation made it possible to decrease milk fat content without changing protein content.
