Milne Animal Nutrition Aids Improved Milk Production 


The health of a dairy cow’s rumen impacts on her ability to convert pasture, fodder and grain/pellet supplements into milk and milk solids. A healthy rumen has many large papillae which increase the surface area to absorb the energy and protein from the breakdown of feed. The more energy and protein that passes through the rumen, the higher the production of milk and milksolids.


Dairy cows grazing high quality, low NDF pastures at this time of the year, in association with starch based grains can develop acidosis. The high sugar content of new, improved pastures can result in rapid fermentation within the rumen and when combined with the fermentation of starch from wheat and barley, can reduce the rumen pH. In cases where the rumen pH falls to very low levels, some or many of the papillae can be “burnt” off, thus reducing the surface area through which the energy and protein sources can pass into the blood stream.  This in turn decreases the pH of the rumen as the acid is not absorbed.  The rumen micro-organisms responsible for the breakdown of forage to energy die off increasing the lactic acid producers. The cow can no longer efficiently convert her feed into milk. This acidosis can result in less milk production, scouring and a low fat test.

One symptom of acidosis is a dramatic fall in the milk fat test of a cow and in severe cases the herd. This can often happen when cows are grazing high quality annual pastures and is put down to a “lack of fibre”. While there is less fibre in the ration at this time of the year, the combination of the fermentable sugars in the pasture and the starch in the cereal grain supplement results in acidosis and a low fat test.

Maximize® is a high starch based energy supplement that has been developed using technology that helps maintain rumen pH at a stable level. When Maximize® is introduced to a herd of cows that are suffering with subclinical and clinical acidosis, the rumen pH is quickly returned to a stable level, resulting in a rapid improvement in milk fat test. A stable rumen, as indicated by a stable milk fat test, is able to more efficiently convert pasture and supplements into milk, resulting in higher production.  To this is the added benefit  of animal welfare (increased comfort, reduced acidosis and bloating risks).
