Good nutrition for cows in dry period can reduce need for culling

New Delhi, June 24, 2018: WITH one in four cull cows reported to leave the herd during the first 60 days of lactation, dairy farmers are being encouraged to pay closer attention to detail during the dry and transition period.

Tom Chanter, InTouch feeding specialist, said: “Good management and nutrition during the dry period is crucial and will support easier calving, improve immunity and increase milk yield during early lactation.

“However, producers typically focus their attention on the milking herd, which means cows are often poorly prepared for calving and transition into lactation.

He said the dry period should not be overlooked and outlined some key areas for producers to consider when it comes to dry cow nutrition.

“Components of the ration, as well as ration presentation, are both important. A high fibre, controlled energy diet, with a crud protein content of between 13 and 14 percent is recommended. Producing an optimal chop length, of between four and six centimetres for optimum intake and effect from fibre.

“Dry cow rations tend to be quite dry which can discourage eating, so ration palatability is key. The optimal dry matter (DM) for a dry cow diet is between 42 to 45 percent. If the mix is very dry, adding water can be an effective way to overcome this.”

Mr Chanter also said the addition of a live yeast can help prepare the rumen for transition onto the milking ration.

“The inclusion of a live yeast, such as Yea-Sacc, will support rumen bacteria and help promote high intakes post-calving. This will support early lactation yields, enabling producers to capitalise on the high levels milk production efficiency a cow is able to achieve during this period.”

He said good mineral nutrition is also critical according to darlingtonandstocktontimes.co.uk.

“A good calcium status is vital, but high-quality trace elements including selenium, zinc and copper should also be provided.

“This is particularly important at times of physiological stress such as calving, as the cow may have a sudden requirement for increased levels of minerals,” he said.

“If not available, cows can be more at risk of metabolic diseases such as ketosis and retained placenta.”
