A Nutritious Forage for Livestock
Barley hay is a popular feed choice for livestock, particularly cattle, sheep, and horses. It’s made from barley plants harvested before the grain is fully developed, ensuring a high-quality hay with a good balance of fibre, protein, and energy.
What is Barley Hay?
Barley hay is harvested from barley plants while they are still in the vegetative stage, before the seeds have fully formed. This early harvest ensures that the hay is rich in nutrients and highly digestible for livestock. It’s known for its soft texture and palatability, making it a preferred choice for many farmers.
Nutritional Value of Barley Hay: NDF, CP, ME
- Crude Protein (CP): Typically ranges from 6% to 12%, depending on the stage of maturity and growing conditions. The protein content can be higher when the barley is harvested earlier in the growing cycle.
- Neutral Detergent Fibre (NDF): The NDF content usually falls between 50% and 70%, providing enough fibre to support healthy digestion in ruminants.
- Metabolizable Energy (ME): Barley hay provides moderate energy, typically around 7-9 MJ/kg, which supports weight maintenance and growth in livestock.
Visual Quality and Grading
The visual quality of barley hay plays a significant role in its palatability and nutritional value. High-quality barley hay should be:
- Green to golden in colour, with minimal yellowing or browning.
- Free of dust, mould, or pests.
- Soft and pleasant-smelling, without any musty or fermented aromas.
Lower-quality barley hay may have a dull colour, a rougher texture, and a higher level of foreign materials such as sticks, stones, or old stubble.
Best Time to Harvest Barley Hay
The optimal time for harvesting barley hay is during the early stages of plant growth, before the grains have fully developed. This ensures the hay maintains its nutritional value, particularly its protein and energy content. Barley hay harvested too late may contain grain, but it can be less digestible and higher in fibre, making it less suitable for some livestock.
Storage and Handling
Proper storage of barley hay is essential to maintain its quality. It should be kept in a dry, well-ventilated area to prevent mould and moisture build-up. Barley hay can lose nutritional value over time if not stored correctly, particularly if exposed to the elements.
