Cattle on low-protein rations may need amino acid supplement to boost milk yield

That's the conclusion of a new study conducted by an international research team led by Alexander Hristov, Penn State distinguished professor of dairy nutrition and a leading authority on greenhouse gas and other emissions from ruminant animals.

A series of experiments, which were published in the Journal of Dairy Science, followed, confirming the importance of histidine to maintain milk production and milk protein content when cows were fed diets with reduced protein concentration. Lactating mammals require large amounts of amino acids to support milk synthesis by mammary glands during lactation, Hristov noted. Amino acid metabolism is a critical process for the lactating mammary gland.

Cattle on low-protein rations may need amino acid supplement to boost milk yieldWhen dairy cows are fed diets with reduced protein concentrations—aimed at decreased environmental nitrogen pollution from their manure such as nitrate leaching, nutrient-laden run-off and ammonia volatilization—their milk production can suffer. Supplementing the amino acid histidine may help in maintaining, and even increasing, milk and milk-protein yields.
