How to Make Silage for Livestock

What is Silage?

Silage is an animal feed made by fermenting green crops until they become acidic. This process is called ensilage or silaging. Silage is commonly fed to cattle, sheep, and other ruminants as a source of nutrition. The fermentation process preserves the crop, making it available for feeding throughout the year. The most common crops used for Silage are grasses like corn, sorghum, and alfalfa.

However, other crops like oats can also be used. The type of crop used determines the term used for the Silage, such as oatlage for oats and haylage for alfalfa. The method of making Silage depends on the available technology, local traditions, and the prevailing climate. Silage is stored in airtight conditions, often under plastic sheeting, to prevent spoilage and leaching of fermented juice.

Importance of Silage in Livestock Farming

Silage is a cost-effective way to provide nutritious feed to livestock. It can be made from different crops, including those unsuitable for other types of animal feed.
Silage has a longer shelf life compared to other forms of feed. Properly made and stored Silage can be fed to livestock for up to a year, reducing the need for frequent harvesting and storage.
Silage is a source of energy and protein for animals. It contains a high level of digestible fiber, promoting gut and overall animal health.
Silage can supplement feed during periods of low forage availability or poor weather conditions, ensuring that livestock receives adequate nutrition year-round.
Silage can also improve milk production in dairy cows and weight gain in beef cattle.

Benefits of Making Silage

Provides a cost-effective and reliable source of nutrition for livestock.
Increases feed efficiency and reduces waste.
Extends the shelf life of crops, reducing the need for frequent harvesting.
It improves animal health and promotes weight gain and milk production.
It can be made from different crops, making it a versatile feed option for livestock.

Common Fodder Crops for Silage Making

Common fodder crops used for silage-making include cereals like maize, sorghum, oats, and millets, legumes such as berseem, lucerne, and cowpea forages like napier and hybrid napier.

Silage Preparation Process / How to Make Silage for Livestock

Choose the type of crop: Choose hybrid and annual plants that grow quickly and can be grown repeatedly. For making Silage, it’s a good idea to grow sorghum, maize, barley, oats, millet, or other grains.
Choose a dry place: Choose a safe and dry place to dig a pit. The pit’s size, form, and dimensions depend on how much forage it can hold.
Cut the greens: After you’ve made the pit, harvest it and cut it into little pieces with a chaff cutter. Make 1-inch pieces out of the greens.
Cover the bottom: Cover the pit’s bottom with a polythene sheet to keep the greens from touching the earth. Cover all of the pit’s sides as well.
Place the chopped greens: Then, into the pit, spread the chopped greens into a thin layer, and continue until one-third of the pit is covered.
Sprinkle molasses: 1 liter of molasses should be diluted with 3 liters of water. And then, uniformly sprinkle the preserved greens with the solution. This feeds the microorganisms and speeds up the fermentation of the Silage.
Press the greens: To force air out and protect the greens against fungal infection, press the greens with your foot or something heavy object.
Add more greens: After pressing and making more places inside the pit. Repeat the molasses sprinkling and pressing. Continue until the pit is filled in a dread form.
Cover the pit: Cover the top with a polythene sheet after the final pressing. Covering the top is critical to preventing water contact with the Silage, and if possible, build a short trench around the pit’s edges.
Cover the pit with soil: Cover the top with dirt and polythene after pressing. This allows air to circulate and protects the polythene from damage caused by rain, birds, or other animals.
Leave the pit: Leave the pit until fodder is scarce, as conservation through fermentation may take many weeks. However, you must wait at least two weeks before utilizing it. Silage produced in this manner can be stored for an extended period, typically up to two years.
Using the Silage: To use the Silage, open the hole from the slope’s lower side. Take enough silage fodder for one day, then close the pit again. When you need Silage for your animals, repeat the process.

Nutrition Value in Silage for Livestock

Silage provides a reliable and cost-effective source of nutrition for livestock and can be substituted for root crops.
Silage increases feed efficiency and reduces waste.
Silage acts as a natural preservative due to the production of volatile fatty acids (VFAs) during fermentation. These VFAs lower the pH and create a hostile environment for spoilage-causing bacteria.
Silage fermentation can also produce vitamins, including folic acid and vitamin B12.
The fermentation process yields energy that bacteria use, which is released as heat. While Silage may be slightly lower in caloric content than the original forage, its improved digestibility and preservation characteristics

Limitations of Silage Making

The initial infrastructure required to set up silos increases investment.
Mismanagement can lead to better-quality Silage, which animals may reject.
Silage has less vitamin D than sun-dried hay.

Silage Feed Preparation Process for Goats

Collect freshly cut grass when it’s still moist and has a high sugar content, ideally in the morning.
Chop the grass into small pieces, about 0.5 inches or 1.3 cm, using a chopper or a machete.
Pack the chopped grass tightly into a silo or container, filling it up to about 75% of its capacity.
Add a silage inoculant containing lactic acid bacteria to speed up and improve fermentation.
Cover the container with a plastic sheet to exclude as much oxygen as possible.
Weigh down the plastic cover with rocks or tires to prevent it from being blown away by wind or animals.
Allow the Silage to ferment for 21 to 30 days or until the pH drops to around 4-5.
Open the silo or container and remove small amounts of Silage as needed, resealing it tightly after each use.
Store the Silage in a cool, dry place to prevent spoilage, mold growth, and nutrient loss.
Properly prepared and stored Silage can be fed to goats for 3-5 months.
Goats must consume 2-5% of body weight fodder daily. For the average dairy goat, 3-4 pounds of Silage.

Silage Feed Preparation Process for Sheep

Collect freshly cut grass when it’s still moist and has high sugar content.
Chop the grass into small pieces using a chopper or a machete.
Pack the chopped grass tightly into a silo or container.
Cover the container with a plastic sheet to exclude as much oxygen as possible.
Weigh down the plastic cover with rocks or tires to prevent it from being blown away by wind or animals.
Allow the Silage to ferment for several weeks or until the pH drops to around 4-5.
Feed the Silage to sheep in small amounts, gradually increasing the quantity.
Avoid feeding spoiled or moldy Silage to sheep, as it can cause digestive problems and other health issues.

Silage Feed Preparation Process for Pigs

Silage is a popular feed for pigs, especially during winter when pasture and other fresh forage may be scarce. To prepare Silage, crops like corn, grass, or alfalfa are chopped, packed tightly into a storage unit, and allowed to ferment. This process creates a nutritious and palatable feed that can be stored for months. When feeding pigs silage, it’s important to ensure it’s fresh and free from mold or other contaminants. Pigs generally consume 8 pounds(3-4kg) of feed per pig per day.

Silage Feed Preparation Process for Cows

Silage is an animal feed that ferments high-moisture fodder crops like corn, grass, and legumes. Making Silage involves chopping up the crops into small pieces and storing them in an airtight container, where natural bacteria break down the sugars and produce lactic acid. This process preserves the feed and enhances its nutritional value for dairy animals like cows.

Molasses, a good source of sugar, should be added to the chopped crop to provide the necessary soluble carbohydrates for organic acid production. The chopped and wilted crop with molasses should then be packed tightly into a silo or container and covered with airtight material to prevent air from entering and spoiling the Silage and generally given about 6 kg to 15 kg of Silage daily.

Silage Storage and Management

Silage can be made from various plants, such as grass, corn, and alfalfa.
The fermentation process typically takes 2-4 weeks, during which the silage temperature may rise due to microbial activity.
It’s crucial to monitor the Silage’s pH level, as a pH below 4.2 inhibits the growth of undesirable microorganisms.
Silage should be stored in a cool, dry place to prevent spoilage and mold growth.
Feed out Silage in small amounts daily to avoid spoilage and feed waste.
Silage that smells musty, has a slimy texture or appears discolored should not be fed to animals.
Silage undergoes four stages in a silo: presealing, fermentation, infiltration, and emptying.
During presealing, respiration and DM loss occur, stopping after a few days. Fermentation occurs over a few weeks, with a drop in pH, more DM loss, and breakdown of hemicellulose.
Infiltration enables limited microbial respiration, causing the loss of available carbohydrates as heat and gas.
Emptying causes additional loss as surface exposure increases.

Tips and Techniques for Preservation of Silage

Cut grass at the right stage of maturity, ideally when the moisture content is around 60-70%.
To promote efficient fermentation, chop the grass into small pieces, about 0.5 inches or 1.3 cm.
Pack the grass tightly into the silo or bales to exclude as much oxygen as possible.
Cover the silo or bales with plastic sheeting to prevent oxygen infiltration.
Use a silage inoculant containing lactic acid bacteria to speed up and improve fermentation.
Monitor the pH of the Silage, aiming for a pH of 4-5, to ensure proper fermentation and prevent undesirable bacterial growth.
Avoid exposing Silage to oxygen until it’s time to feed, and only remove small amounts of Silage at a time to minimize spoilage.
Store silage in a cool, dry place to prevent mold growth and nutrient loss.
