Milk Quality Measures Can Identify Missing Yield Potential

An annual pattern of milk composition has been well recognized on dairy farms across the world for years, with the highest milk fat and protein concentration in milk observed during the winter and lowest occurring in the summer. This trend is manipulated solely by season, and impacts housed and grazing cows similarly. So, when we get to spring, and then turnout for some, and milk butterfats start to decline- how do we know if this is real milk fat depression or not?

RumiStar™: maximising starch availability from maize based diets

In order to maximise profitability from the production of cow’s milk, farmers are increasingly focused on improving the efficiency of feed and animal production. One method to consider is the use of feed additives, such as RumiStar™, to optimise health and well-being.

Dairy farmers can achieve efficient milk production by investing in high quality genetics, but this can depend on good management and high quality rations. Evidence from trials and practical experience indicates that a reliable and cost-effective way of earning more profit per cow is through optimising feed with the right additives. This is important for farmers not only to ensure that milk production is profitable, but also to ensure optimal rumen health and well-being for cows.

To get the most from a dairy cow, you must get the most from the animal’s rumen. The rumen is the engine of milk production. RumiStar™ is a product that can get you a turbo charged engine and better profits. When you feed a dairy cow, you are feeding the billions of microorganisms in its rumen. Many factors affect the performance of the rumen, get them right and you will have more productive cows with better feed efficiency.

The rumen is populated by vital microorganisms that digest the diet. Fine tuning the rumen means maintaining these in an optimal state. This increases the energy and protein available to the cow from its feed. Sometimes the rumen needs a helping hand; for example, in order to extract a higher value from high starchy maize.

From carrying out on-farm digestion analysis, we can evaluate the cows’ dung. Analysing digestion by muck sieving we can adjust diets accordingly, promoting good rumen efficiency and optimal rumen nutrient balance. The Nasco Three Sieve analyser is a fantastic tool to use, as it shows how well the cows are digesting the diet. Those herds with a high percentage of corn in the dung will be losing a high amount of potential energy, therefore, potential milk loss which equates to lost income.
RumiStar™ is a cutting edge feed enzyme specifically developed for dairy cows. It increases corn starch digestion; increases energy supply and allows more milk to be produced from the same feed; greater feed efficiency and more income.

How It Works
A pure amylase (an enzyme, found in saliva and pancreatic fluid, that converts starch and glycogen into simple sugars), it releases more of the starch energy in corn based diets. This provides more starch energy to the animal and also increases forage digestion. As a result, cows make better use of their total diet and can allow increased forage use, which reduces feed costs.

Where cows are fed RumiStar™ I have seen much higher corn digestion and overall forage digestion, and rumen fill has been very consistent. Results from the UK and rest of Europe can conclude a response in milk production of an extra 1.5-1.8 kg/cow. A significant rise in efficiency and financial returns have increased.

RumiStar™ Benefits
• Better adoption and utilisation of maize based diets
• Better digestion of dietary starch and NDF
• Glucogenic effect; higher blood glucose, important link to fertility
• Better rumen health
