Meeting your objectives

We know that as dairy farmers you’re faced with three main goals that chop and change depending on your cow’s stage in the lactation cycle, with overall herd health a permanent consideration when trying to get the best out of your cows. All three of these objectives can be targeted with the support of one key nutritional component – FAT.

These objectives are:

  • More milk
  • More milk fat
  • Better fertility

The Megalac know-how

Our extensive research has demonstrated that there are two major fatty acid players in the diets of dairy cows when it comes to supplementing for peak productivity – C16:0 (palmitic acid) and C18:1 (oleic acid).

With C16:0 fundamental for stimulating milk fat production and C18:1 known to aid Body Condition Score (BCS) and fertility, it’s easy to see how adjusting the ratios of each according to the stage of lactation and challenges you are facing, can result in your goals being achieved.

Every objective covered

Every product in our range is formulated with a carefully balanced fatty acid profile for the specific outcome in mind. Some, depending on when they are fed, can address multiple issues...
