How Hay Wrap Film Improves the Nutrition of Livestock Feed

Hay wrap bales can be easily stacked and stored

Silage: that mysterious, often pungent feedstuff that finds its way into the diets of livestock across the globe. But what exactly is silage, and why is it considered superior to regular grasses in terms of nutrition? The answer lies in the fascinating science of fermentation, aided by hay wrap film and storage solutions. This enhances the nutritional value of forage and offers economic advantages.

In this blog, we'll delve into the science behind silage, explore its nutritional benefits, discuss cost-efficiency, and even take a trip back in time to discover its origins.

The Discovery of Silage

The concept of silage dates back centuries, with its roots in the preservation of forage for livestock during harsh winters. Ancient farmers discovered that by burying green vegetation in pits or mounds and packing it tightly, they could create a feed source that remained nutritious and palatable throughout the winter.

However, the true modern understanding and widespread use of silage began in the late 19th century when scientists and agricultural pioneers like Auguste Goffart and William Shaw developed and promoted silage-making techniques. These innovations led to the development of the silo, which revolutionized the way farmers stored and preserved forage. Today, many farmers use the hay wrap technique, which eliminates the need to have a silo constructed.

The Science of Silage

Silage is essentially forage, such as grasses or corn, that has undergone a fermentation process through the use of hay wrap film to preserve and enhance its nutritional content. The secret sauce here is lactic acid bacteria, which play a pivotal role in the fermentation process. Let's break it down step by step:

The journey to creating silage begins with the harvest. Forage crops, typically grasses or corn, are cut at the peak of their nutritional value. Timing is crucial, as you want to capture the maximum nutritional content before it starts to deteriorate. The harvested forage is then chopped into smaller pieces. This increases the surface area exposed to the next critical ingredient: lactic acid bacteria.

The chopped forage is densely packed into bales secured by hay wrap film. Wrapping the bales tightly ensures that minimal oxygen is present. Oxygen is the enemy of fermentation in this case, so sealing the forage tightly is essential.

Lactic acid bacteria, naturally present on the forage or introduced as an inoculant, break down the sugars in the forage into lactic acid. This drop in pH creates an acidic environment that preserves the forage and prevents spoilage by harmful microbes.

Nutritional Advantages of Silage

During fermentation, the forage is preserved by the hay wrap, and its nutritional profile is enhanced. The lactic acid produced during this process helps break down complex carbohydrates into simpler, more digestible forms. This makes the nutrients in silage more readily available for the animals that consume it.

Higher Nutrient Retention

The fermentation process preserves the forage, locking in essential nutrients such as proteins, vitamins, and minerals. This means that when livestock consume silage, they're getting a more concentrated dose of nutrition compared to dried grasses.

Improved Digestibility

Silage's lower pH and the breakdown of complex carbohydrates result in improved digestibility. Livestock can absorb and utilize the nutrients more efficiently, promoting better growth and health.

Reduced Waste

Unlike dried grasses, silage is less prone to being scattered or trampled by livestock by chopping it into smaller pieces. While this is done primarily to help the fermentation process, it also reduces waste. More of the feed ends up in the animals' bellies, translating to cost savings.


Silage offers a consistent nutritional profile throughout the year. In contrast, the quality of dried grasses can vary depending on factors like weather and harvest timing, making it harder to meet the dietary needs of your livestock consistently.

Economic Benefits of Silage

Beyond its nutritional advantages, silage can also provide significant economic benefits to your farming operation.

Lower Harvest Costs

Harvesting silage involves fewer expenses compared to drying and baling hay. You don't need to wait for perfect weather conditions, and you can efficiently use machinery to chop and pack the forage.

Reduced Labor Costs

Silage production is highly mechanized, reducing the need for manual labor during harvest. This means lower labor costs and less reliance on seasonal labor.

Year-round Feeding

With silage, you have a continuous supply of nutritious forage regardless of the season. This eliminates the need to stockpile large quantities of hay, feeds, or other supplements during the winter months, saving on storage costs.

Increased Productivity

The improved nutrition from silage can lead to increased livestock productivity, such as higher milk yields in dairy cows and faster weight gain in beef cattle. This, in turn, can boost your farm's revenue.
