High grain yields boost silage

According to Jason Scott of Pioneer Brand Seeds, to maximize economic returns, corn crops grown specifically for silage production must have a high grain yield to provide the best overall forage quality.

Research has shown that the forage quality of corn leaves and stalks, called stalk, varies between hybrids, but to maximize milk and animal production potential, grain yield will have the greatest influence.

“The highest grain yield provides the best overall forage quality, so it makes sense to choose a high grain yield hybrid,” Scott said.

“Grain provides, roughly, about 50% of the yield of silage. About 65 percent of silage’s metabolizable energy comes from grain, and grain provides 80 percent more energy than stalks on a pound-for-pound basis.

“That’s why you need a high-yielding grain hybrid to start with, for silage.

Inoculants improve corn silage fermentation, reducing losses and improving silage performance when fed to livestock.

“Medium and fast maturing hybrids are generally best at providing the best mix of digestibility and metabolizable energy. They can produce good kernels and provide quality stalks at the right dry matter content.

Pioneer has observed a trend among producers to select hybrids in maturity categories below 118 CRM for silage.

“These hybrids allow growers to increase the rate of crop rotation, mitigate the risk of early season frost and wet weather, and have enough water to bring the crop up to material content. dries 34 to 38 percent for optimal silage production,” said Scott.

“We are seeing silage growers aiming for higher plant densities with the low CRM hybrids, around 10-20% more than with a cereal crop, and this gives them the ability to achieve the amount of silage more the ideal quality they are looking for.”

He recommended seeking advice from an agronomist or seed sales manager, as forage quality could be reduced by lower grain production where very high plant populations were used.

“Selecting the right hybrid for your growing environment and managing that crop for the conditions it will encounter is important to achieving your silage goal.”

Mr. Scott also advised that in addition to agronomic factors, growers should not forget the importance of selecting the correct bacterial inoculant to apply at the harvest stage.

Pioneer has been researching and identifying safe and effective bacterial strains for use in silage additives and inoculants since 1978, and has developed a broad portfolio of crop-specific inoculants.

“A properly inoculated and ensiled silage pit will have minimal activity on the silage face at the exit, reducing the risk of spoilage losses and herd health issues,” Scott said.

Pioneer has marketed the first proprietary inoculant containing L. buchneri— the leading bacterial strain of choice for keeping silage pits fresh and preventing feed loss due to yeast and mold growth — in 2000.

“Pioneer has made progress since then,” Scott said.

“We know that an inoculant that reduces pH below 4.5 in a fast and effective action will have a reduced risk of spoilage through slow fermentation.

“So in 2016 we introduced our Rapid React technology products which contain a new L. buchneri strain that works to produce stable silage in just seven days.

“With the characteristics of a fast-seasoning corn hybrid like Pioneer P9911 paired with Pioneer-brand 11C33 inoculant with Rapid React, dairy farmers are able to harvest and ensile for maximum energy and production. maximum milk.

Pioneer has also supported the advancement of inoculant technology with the development of an application system designed and calibrated specifically for Pioneer brand inoculant products.

“The unique design of the Appli-Pro application system reduces water requirements and provides a high level of application precision and convenience,” Scott said.

The Appli-Pro has been designed to work with all major brands of forage harvesting equipment and allows the operator to use the easily calibrated cab-mounted control panel to turn the applicator on and off to precisely control the rate of application.

Controls are available in wired mode or via the iPad app, to suit operator and cabin configuration.

The extremely low application rate of the Appli-Pro application system and the non-requirement to pre-mix the inoculant before filling the tank allows for reduced downtime and increased chopping or setting time. balls.
