Why Blood Meal Replacement?
Today's dairy cow rations are precisely balanced, but feedstuff quality is variable. This results in less metabolizable protein (MP lysine) than what is accounted for during feed formulation. Additionally, studies suggest that increasing MP lysine by 10 grams/head/day can increase milk production by reducing the risk of underfeeding lysine.
Helping You Close The Gap
Milk production is maximized when nutrient requirements are met. NRC 2001 meta-analysis identifies 7.2% MP lysine as the target.
- Meeting nutrient requirements to achieve maximum milk production
- Inadequacies of blood meal
- Producers no longer stuck with practical recommendations
Formulating For Optimum Lysine
In a 2009 study published in the Journal of Dairy Science, researchers looked at grams of lysine and milk protein yield. The researchers concluded that increased lysine levels support the possibility of higher milk protein yield. See chart below for the linear relationship between lysine and milk protein yield.
Energy Corrected Milk vs. Grams of MP Lysine
The figure below plots trials that reported MP lysine in diet and energy corrected milk values. Studies were split into high-, mid- and low-producing herds. Results showed more grams of MP lysine means more milk.
