How To Make High Quality Hay: 10 steps to success

Producing high-quality hay is essential for ensuring nutritious and palatable forage for livestock. To achieve this, several key factors and steps must be considered throughout the hay production process.

This article provides a comprehensive guide on how to make high-quality hay, covering factors that determine hay quality and the steps you should follow to optimize hay production.

Factors Determining Hay Quality

Hay quality is influenced by various factors that affect its nutritional value, palatability, and overall quality. Understanding and addressing these factors are crucial for producing high-quality hay. The following are the key factors that determine hay quality.

Species and Variety of Grass

The selection of the appropriate grass species and variety plays a significant role in hay quality. Different grasses have varying nutritional compositions and palatability. Consider the specific grass species and variety that are suitable for your region and livestock requirements to achieve optimal hay quality.

Stage of Maturity at Harvest

Harvesting hay at the right stage of maturity is critical. Grasses become less nutritious as they mature, with higher fiber content and lower nutrient levels. Cut the grass during the early to mid-maturity stage, just before it becomes too mature or starts to flower excessively. This ensures higher nutrient levels, improved digestibility, and enhanced forage quality. We discuss this more in detail later in this article.

Drying and Moisture Content

Proper drying and moisture management are essential for maintaining hay quality.

Hay should be dried to an appropriate moisture level (around 10% to 20%, depending on the type of hay) before baling to prevent spoilage and nutrient degradation.

Monitor weather conditions closely and aim for a period of dry weather with minimal rain when planning to cut hay. Spread the cut grass evenly in the field to promote faster and more uniform drying. Regularly monitor the moisture content using a moisture meter or other testing methods to ensure it reaches the desired level.

Leaf-to-Stem Ratio

The leaf-to-stem ratio in hay is an important indicator of quality. Leaves contain higher nutrient concentrations compared to stems, so a higher leaf-to-stem ratio indicates superior nutritional value. Handle the hay carefully during cutting, drying, and baling processes to minimize leaf loss and preserve the leaf content.

Color and Aroma

The color and aroma of hay can be indicative of its quality. High-quality hay typically exhibits a vibrant green color (unless it’s a naturally brown or mixed-grass hay) and a pleasant, fresh smell.

Faded or yellowed hay may suggest nutrient degradation or poor drying conditions. A musty or moldy odor can indicate spoilage or insufficient drying. Regularly inspect the hay for any signs of discoloration or unusual odors.

Weed and Foreign Material Content

The presence of weeds, dirt, dust, and other foreign materials can significantly affect hay quality. Weeds can be less palatable or even harmful to livestock, while excessive dirt or dust can introduce unwanted bacteria which can cause the hay to rot.

Implement good weed control practices such as removing buttercups, docks and rushes. Carefully handle the hay to minimize the presence of undesirable materials.

Storage Conditions

Proper storage is crucial for maintaining hay quality. Store the baled hay in a well-ventilated, dry shed or barn to protect it from moisture, rain, and excessive sunlight.

Ensure proper air circulation around the bales to prevent heat buildup and mold growth. Regularly inspect the stored hay for signs of spoilage, mold growth, or insect infestation. Remove any damaged or spoiled bales promptly to prevent the spread of issues to surrounding bales.

What is the best way to assess the moisture content of hay?

Assessing the moisture content of hay is crucial for determining its readiness for baling and storage. There are several methods you can use to measure the moisture content effectively. Here are some commonly used techniques:

Moisture Meter:

A hay moisture meter is a handy tool specifically designed for measuring the moisture content of various materials, including hay. It works by using electrical conductivity to determine the moisture level.

The moisture meter has prongs or sensors that are inserted into the hay bale or flakes, and it provides a digital reading of the moisture content. Different moisture meters are available for different types of hay, such as small square bales or large round bales.

Microwave Oven Method:

This method involves using a microwave oven to quickly assess the moisture content of hay samples. Take a representative sample of the hay and weigh it. Then, place the sample in a microwave-safe container and heat it in the microwave oven for a specific period.

After heating, weigh the sample again. The difference in weight represents the moisture loss, which can be used to calculate the moisture content of the hay.

Koster Tester:

A Koster tester is a device commonly used for assessing the moisture content of hay in the field. It consists of a metal container that holds the hay sample and a pressure gauge.

The hay sample is placed inside the container, and pressure is applied to compress the hay. The gauge provides a reading based on the compression force required, which can be used to estimate the moisture content of the hay.

Visual and Manual Inspection:

While not as accurate as the previous methods, visual and manual inspection can provide some indication of hay moisture content. Experienced hay producers can assess moisture levels by observing the color, texture, and pliability of the hay.

They can also perform a “squeeze test” by squeezing a handful of hay tightly and then releasing it. If the hay quickly expands back to its original shape, it suggests a lower moisture content. However, this method relies on the expertise and subjective judgment of the individual.

It is important to note that different types of hay may require different moisture content ranges for optimal storage and quality. Therefore, it is advisable to consult local agricultural extension services, hay experts, or agricultural laboratories for specific recommendations and guidelines regarding moisture content assessment for the particular type of hay you are working with.

By utilizing appropriate moisture assessment methods, you can ensure that your hay is properly dried and ready for baling and storage, minimizing the risk of spoilage and maintaining high-quality forage for your livestock.

At what stage of growth should grass be cut for hay and is this different for European and American grasses?

The stage of growth at which grass should be cut for hay can vary depending on multiple factors, including the type of grass, local climate, and intended use of the hay. While there may be some variations between European and American grasses, the general principles remain similar. Here’s a guideline on when to cut grass for hay:

  1. Early Maturity Stage: Generally, grasses intended for hay production are cut during the early maturity stage, also known as the pre-bloom stage. At this stage, grass has reached a sufficient height and has developed a good leaf-to-stem ratio. It offers a balance between nutrient content and yield.
  2. Timing for European Grasses: In Europe, common grass species used for hay production include timothy, meadow fescue, and perennial ryegrass. These grasses are typically cut for hay when they are in the boot to early-heading stage, just before they begin to flower. At this stage, the grasses have high nutritional value and good palatability.
  3. Timing for American Grasses: In the United States, common grass species used for hay production include orchard grass, tall fescue, and Kentucky bluegrass, among others. These grasses are often cut for hay when they are in the late vegetative to early-heading stage, before the seed heads fully emerge. This stage ensures good nutrient content and palatability.
It’s important to note that the timing of grass cutting may also depend on the specific objectives of the hay production. For example, if the goal is to produce hay with high protein content, cutting the grass at an earlier stage of maturity may be preferred. Or, if the focus is on maximizing yield, cutting the grass slightly later in its growth stage might be more suitable.

Regardless of the grass type or location, it is essential to closely monitor the growth stages of the grass and cut it before it becomes too mature or starts to flower excessively.

As grass matures further, it tends to have higher fiber content and lower nutrient levels, which can reduce its nutritional value as hay.

Consulting with local agricultural experts, extension services, or experienced hay producers in your specific region can provide valuable insights into the optimal stage of growth for cutting grass for hay production. They can offer recommendations tailored to your local climate, grass species, and specific objectives, helping you achieve high-quality hay for your livestock.

How To Make High Quality Hay In 10 Steps

Make note of these 10 actionable steps to making high-quality hay.

1. Timing of Cutting:

Determine the optimal stage of maturity for the specific grass species or mixtures you are growing. Cut the grass at the early to mid-maturity stage, just before it starts to flower and seed excessively. This stage ensures the best balance between nutrient content and yield.

2. Weather Conditions:

Monitor weather conditions closely when planning to cut hay. Aim for a period of dry weather with minimal rain in the forecast. Wet or damp conditions can delay drying and increase the risk of mold growth and nutrient loss. Avoid cutting during periods of high humidity or rain.

3. Cutting Height:

Set the cutting height of the mower correctly to leave an appropriate stubble height. This helps preserve the regrowth potential of the grass and reduces contamination from soil and debris.

4. Tedding:

Tedding is the process of spreading the grass across the surface of the field to speed up drying. Tedding will spread and fluff the grass up to allow more air to circulate. By increasing the surface area of the grass, the sun can dry it much quicker.

Tedding grass for silage, but the same applies to making hay – it is just left to dry for longer.

5. Drying:

Allow the cut grass to dry in the field until it reaches the desired moisture content for baling (around 10% to 20%, depending on the type of hay). To speed up drying, spread the windrows evenly and consider tedding or raking the hay to expose it to air and sunlight.

6. Moisture Content Testing:

Regularly monitor the moisture content of the hay using a moisture meter or other testing methods. This ensures that the hay is dried to the appropriate moisture level before baling to prevent spoilage and nutrient degradation.

7. Baling:

Once the hay has reached the desired moisture content, it can be baled. Use well-maintained balers that produce tight, uniform bales. Proper bale density and shape help minimize spoilage and maintain hay quality during storage.

8. Storage:

Store the baled hay in a well-ventilated, dry shed or barn to protect it from moisture, rain, and excessive sunlight. Ensure proper air circulation around the bales to prevent heat buildup and mold growth. Stack the bales on pallets or well-drained surfaces to prevent contact with the ground.

9. Regular Inspections:

Regularly inspect stored hay for signs of spoilage, mold growth, or insect infestation. Remove any damaged or spoiled bales promptly to prevent the spread of issues to surrounding bales.

10. Nutritional Analysis:

Consider obtaining nutritional analysis of your hay through laboratory testing. This provides valuable information about the hay’s nutritional composition, allowing for better livestock feeding and balanced diets.

By following these steps and implementing good hay production practices, you can maximize the quality, nutrient content, and palatability of your hay. It is important to adapt these steps to local conditions, grass species, and specific hay production goals. Regular monitoring and continuous improvement in hay production techniques will help you consistently produce high-quality forage for your livestock.
