Lactipro Advance® can be used in a receiving program aimed at:
- Stepping up cattle to a more energy dense diet faster.
- Optimizing energy density of the diet.
For rapid and efficient growth, the challenge is to maximize your animal's energy intake as soon as possible after their arrival at the feedlot. This involves feeding increased levels of high-concentrate diets rich in rapidly fermentable carbohydrates (RFCs). During transition from typical roughage diets fed before feedlot entry to high-concentrate feedlot diets, rumen microorganisms need time to adapt from predominantly fiber digestion to digestion of more rapidly fermented carbohydrates.
Lactic Acid Production
As these microorganisms adapt to high-concentrate diets, they convert the starch components into desirable volatile fatty acids (VFAs). However, even under careful diet management rumen conditions can favor the production of lactic acid, by bacteria such as Streptococcus bovis and lactobacilli. Lactic Acid is a 10-times stronger acid than VFAs and is responsible for severe drops in rumen pH.
Megasphaera elsdenii: The Lactic Acid-Utilizer
Megasphaera elsdenii is the most important lactic acid-utilizing microorganism in cattle during the adaption to and feeding of high-concentrate diets. It plays a critical role in preventing the buildup of lactic acid in the rumen. However, Megasphaera elsdenii numbers are often low when cattle are fed roughage or low-concentrate diets and need time to increase to levels capable of handling high-concentrate diets. Conventional methods of adaptation take this into account by offering multiple step-up diets over several weeks. This extra time and added management of step-up diets leads to inefficiencies.

Lactipro Advance® Robust Strain of Megasphaera elsdenii
Lactipro Advance® contains 2x10^8 cfu/ml. of viable cells of a patented Megasphaera elsdenii strain, isolated from the rumen of a concentrate-adapted high producing dairy cow. Drenching cattle with Lactipro Advance® supplies an immediate population of this potent and resilient lactic acid-utilizing Megasphaera elsdenii in the rumen to supplement the animal's own Megasphaera elsdenii population and to respond to the change from roughage to high-concentrate diets.
