Increase N efficiency for cheaper milking

tue, 10 mar 2015
The necessity to work on enhancing N and P efficiency in dairy cattle is increasing. How can you achieve this without making feed more expensive? The current lower milk prices - and the super levy for a number of livestock farmers - leave little room for purchasing more expensive feedstuffs for better mineral efficiency. After abolishing the milk quota, adequate N and P efficiency seems to become a necessity to retain the ‘licence to produce’. Both at stable level and country level, the use of these two elements in particular is scrutinised and must increasingly be accounted for in more detail.

Fortunately, feed that results in better efficiency can also be cheaper. For example by applying bypass protein and urea. With a combination of both, a cow can produce at least as efficiently as based on regular protein feed.

Protein can pass the rumen in various ways, where the units are broken down into ammonia, partially into amino acids, or is not broken down at all. Bypass protein is not broken down in the rumen, but is easy to digest in the intestines, and this results in the most efficient path. Using the MervoBest products that were made resistant, the raw protein content of the feed can be decreased, allowing for increased N and P efficiency. With lower protein content, the phosphor content is generally also lower.

The protein that is broken down in the rumen may in part be derived from non-protein nitrogen (NPN). In particular the rumen microbes that break down cell walls need NPN, rather than amino acids from true protein. With the right dose per cow per day, you can achieve higher feed efficiency than when using a regular source of protein. MervoBest resistant protein and NPN enable you to milk cheaper with better efficiency of both nitrogen and phosphor.
