Making clean, quality grass silage is key to offset rising feed prices
Experts are urging livestock producers to make the best silage possible this season as purchased feed, energy and other inputs continue to rise. Granted, the cost of making grass silage has also risen due to widespread inflation effecting energy and input costs. However, it still offers exceptionally good value — costing around 60 euro per tonne to produce— and will be crucial to offsetting higher feed costs, especially if corn silage quality and yields were affected by the drought conditions seen in 2022. Making small changes to your grass silage production process can achieve incremental improvements in silage quality and palatability, which offer significant cost benefits when fed.
Cleaner silage
When it comes to making the best silage possible, management from the field to the bunker/silo is critical. Using MAGNIVA condition-specific inoculants are also crucial as inoculants ensure an efficient fermentation and reduce undesirable microbial growth, which ensures the silage made is clean as well as nutrient and energy rich.
Trials show that after 30 days ensiling and five days after opening, MAGNIVA Platinum reduces yeast and mold levels by over 100 times compared to untreated grass silage (Figure 1).

Maintain nutritional value
Making cleaner silage by controlling both yeast and mold growth through the ensiling and aerobic exposure periods results in a silage that better maintains nutritional and energy levels compared to untreated grass silage.
This was highlighted in independent analysis of more than 100 first-cut grass silage samples undertaken by Trouw Nutrition (UK), which clearly shows that using MAGNIVA inoculants results in grass silage with higher energy (ME), improved digestibility and protein levels compared to untreated grass silage (Table 1).

Improve return on investment
The resulting improvement in energy and protein levels seen in MAGNIVA treated grass silages has a positive impact on milk and meat production as the maintained feed quality of MAGNIVA grass silage means there’s a reduced reliance on costly purchased feed.
Even taking the cost of the inoculant into account, MAGNIVA treated grass silage offers a significant return on investment (ROI) for the producer: up to 1:7 ROI has been calculated.
Making small changes to grass silage management practices such as: ensuring optimum cutting times, using best practices during silo filling and ensiling, and applying MAGNIVA forage inoculants can result in significant improvements of grass silage quality.
