Recent research from Michigan State suggests that feeding a more balanced approach (60:30 palmitic versus oleic) in early lactation results in:

• Significant gains in energy-corrected milk (ECM)
• Increases in dry matter intake (DMI)
• Reduced body weight loss versus the higher palmitic treatment (80% Palmitic:10% Oleic)
• Be sure to assess the Palmitic:Oleic balance in the whole diet, as these fatty acids come from other feeds besides your fat supplement
