Dairy farmers are being urged to start planning for winter feeding to ensure cows receive consistent rations and achieve optimum milk yields.

With varying silage quality experienced this year, producers are being encouraged to undertake analysis of forages to gain an accurate picture of the quality of their silages.

"Measuring silage clamps and assessing the quantity of forages available to them is equally important," said Csaba Adamik, Lallemand Animal Nutrition's regional business manager for Scotland.

He says once farmers are aware of this, they can plan ahead to ensure their rations are balanced to meet their cows' needs.

"In instances where silage quality changes throughout winter, rations should be reformulated to maintain optimum nutrient levels."

He added that farmers must also pay close attention to clamp management and aim to feed a consistent ration every day.

"To achieve this while minimising waste, producers should feed out in a vertical column from the clamp to ensure silage quality is consistent in every mix," he explains.

"Producers should also aim to move across the whole clamp face in less than three or four days. In case of very wide clamp faces, taking shallower grabs, rather than full grabs will help to avoid silage being exposed to oxygen for too long, as that can affect aerobic stability of the silage negatively."

How the ration is delivered, is another area of focus as feeding out wagon mix rations between milkings, and not at milking time, has been shown to increase feeding bouts which can improve feed efficiency by as much as 7%.

Pushing feed up regularly and feeding twice a day or more increases dry matter intakes, reduces sorting, and leads to increased lying time and improved rumination activity."

He says feeding a rumen-specific live yeast, like Levucell SC, can help balance rations, while also delivering environmental benefits.

"The yeast works by optimising rumen function, increasing ration digestibility and feed efficiency - ensuring cows get the most out of the feed available to them," explains Mr Adamik.

"Studies have shown that inclusion of the live yeast in rations improves feed efficiency by 3-6% in lactation and subsequently reduces the carbon footprint of milk production by up to 6%.

"When fed prior to calving, the yeast reduces body weight loss and promotes early lactation feed intake. This, combined with the improved feed efficiency during lactation has the potential to improve milk yields by up to 8%, making a significant contribution to sustainable milk production," adds Mr Adamik.
