To optimise dairy herd productivity you need healthy, fertile, cows that produce good volumes of milk with high constituent values. Trouw nutrition’s Grass Watch to date indicates grass yields are generally lower and are also low in fibre, giving rise to rumen acid loading and high risk of low butter fats.
Therefore, it is vital that grazing is measured and managed for quality & quantity so it can be balanced with the correct choice of energy sources and buffer feeding. This ensures effective rumen fermentation and maximises dry matter intake (DMI).
Grass Watch also indicates grazing is high in rapidly fermentable carbohydrates (RFC’s) and adding more starches & sugars to the feed will only increase the rumen acid loading. Therefore, to balance this, we need to add effective fibre based feeds. To ensure energy requirements are met and cows are kept healthy and fertile, a balanced, highly digestibly rumen inert fat should be added.
Importantly at this time of the year, adding a balanced rumen inert fat, which is digested in the small intestine, has the added benefit of not generating heat in the rumen. Consequently, it does not add to the DMI reduction often seen in the summer, as a result of the increase in the temperature humidity index (THI).
Feeding a combination of UFAC Dynalac and Glyco-buf will provide the cow everything she needs to maintain the correct rumen pH, milk quality, herd health and fertility, all of which are at potential risk.
