Forage is a VERY extensive topic, so to keep this post relatively short, I'll attempt to condense this in a nutshell. A horse's diet should primarily consist of structural (fiber) carbohydrates, mainly from forage. Fiber plays a crucial role in promoting healthy digestion and serves as a significant energy source for hindgut microbes. However, ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ ฬฒ๐ฬฒฬฒ๐ฬฒ ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ; poor-quality forage can harm your horse's health.

When assessing hay quality, it's essential to consider nutritional value and ๐ญ๐ก๐ ๐จ๐ง๐ฅ๐ฒ ๐ฐ๐๐ฒ ๐ญ๐จ ๐ค๐ง๐จ๐ฐ ๐ญ๐ก๐ ๐ง๐ฎ๐ญ๐ซ๐ข๐ญ๐ข๐จ๐ง๐๐ฅ ๐๐จ๐ง๐ญ๐๐ง๐ญ ๐จ๐ ๐ญ๐ก๐ ๐ก๐๐ฒ ๐ข๐ฌ ๐ญ๐จ ๐๐๐ญ๐ฎ๐๐ฅ๐ฅ๐ฒ ๐ก๐๐ฏ๐ ๐ ๐๐จ๐ซ๐๐ ๐ ๐๐ง๐๐ฅ๐ฒ๐ฌ๐ข๐ฌ ๐๐จ๐ง๐ and ๐ข๐ง๐ญ๐๐ซ๐ฉ๐ซ๐๐ญ๐๐ ๐๐ฒ ๐ฌ๐จ๐ฆ๐๐จ๐ง๐ ๐ฐ๐ก๐จ ๐ฎ๐ง๐๐๐ซ๐ฌ๐ญ๐๐ง๐๐ฌ ๐ก๐จ๐ฐ ๐ญ๐จ๐จ. However, along with the ๐ข๐ฏ๐ข๐ญ๐บ๐ต๐ช๐ค๐ข๐ญ ๐ฒ๐ถ๐ข๐ญ๐ช๐ต๐บ, there is an ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ ฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒ we need to look at as well. The nutritional value of hay is largely influenced by the ๐ฆ๐๐ญ๐ฎ๐ซ๐ข๐ญ๐ฒ ๐ฌ๐ญ๐๐ ๐ of the plants at harvest. Plant fiber consists of a fiber called ๐ฅ๐ข๐ ๐ง๐ข๐ง ๐ฐ๐ก๐ข๐๐ก ๐๐๐ง๐ง๐จ๐ญ ๐๐ ๐๐ข๐ ๐๐ฌ๐ญ๐๐ ๐๐ฒ ๐ญ๐ก๐ ๐ก๐จ๐ซ๐ฌ๐. As plants age and mature, the levels of lignin within them tend to increase. For instance, coarse hay typically contains higher concentrations of lignin.

This means that forage harvested at the appropriate stage of growth is essential for optimal digestion and nutrition for horses. โฃ

To help determine if hay is of adequate quality is, break open a bale and check for:โฃ
โฃ
1) ๐๐ญ๐๐ ๐ ๐จ๐ ๐ก๐๐ซ๐ฏ๐๐ฌ๐ญ - Look for a ๐ก๐ข๐ ๐ก ๐ฅ๐๐๐-๐ญ๐จ-๐ฌ๐ญ๐๐ฆ ๐ซ๐๐ญ๐ข๐จ. If the hay appears to have mostly thick stalks, it indicates that it was cut too late, resulting in a high lignin content, which is not ideal for feeding your horse. Instead, seek hay that has been cut earlier, as this will typically contain more flat leaves, fine stems, and fewer seed heads. For instance, grass and alfalfa should ideally be cut in the pre-bloom stage. For timothy hay, the head length should be in bud form or less than 1 inch long, while alfalfa should be harvested before it blooms. Hay that contains ๐ฉ๐ฅ๐๐ง๐ญ๐ฒ ๐จ๐ ๐ฅ๐๐๐ฏ๐๐ฌ, ๐๐ข๐ง๐ ๐ฌ๐ญ๐๐ฆ๐ฌ, ๐๐ง๐ ๐ฆ๐ข๐ง๐ข๐ฆ๐๐ฅ ๐ฌ๐๐๐ ๐ก๐๐๐๐ฌ suggests that it is from an early maturity plant, which is beneficial for horses.โฃ
โฃ
2) ๐๐ก๐ ๐ฌ๐ช๐ฎ๐๐๐ณ๐ ๐ญ๐๐ฌ๐ญ - When you pick up a handful of hay, does it feel soft and pliable, as small stems and flat leaves should, or does it feel harsh, pokey and brittle? Good quality hay should feel very ๐ฌ๐จ๐๐ญ ๐๐ง๐ ๐ฉ๐ฅ๐ข๐๐๐ฅ๐, and it should feel pleasant in your hand.โฃ
โฃ
3) ๐๐ฆ๐๐ฅ๐ฅ ๐ฒ๐จ๐ฎ๐ซ ๐ก๐๐ฒ - Doesn't the smell of freshly cut grass smell wonderful? Good quality hay has a clean, pleasant aroma known as "crop odour". If hay has musty, mouldy, or burnt odours, it's an indication of poor quality, can decrease your horse's willingness to eat it and cause further health issues.โฃ
โฃ
4) ๐๐ก๐ ๐๐๐ฌ - ๐๐จ๐ฅ๐จ๐ซ ๐๐ง๐ ๐๐ฅ๐๐๐ง๐ฅ๐ข๐ง๐๐ฌ๐ฌ - The exterior of a hay bale often fades because of sun exposure, which is normal. However, the inside of the bale should be a bright green color. If the hay appears yellow, brown, black, or white, it indicates poor quality, suggesting that the hay is old, mouldy, or has been stored improperly. Additionally, the hay should be completely free of trash, weeds, dirt, and dust. โฃ
โฃ
Ensuring these points, and having earlier cut hay ฬฒ๐ฬฒฬฒ๐ขฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ฬฒฬฒ๐ขฬฒ means higher digestibility and nutrient content for your horse, although this can be fully confirmed by a hay analysis. It's important to understand that, just like we gradually introduce a new grain to a horse over a period of 10 to 14 days, ๐ฐ๐ ๐ฌ๐ก๐จ๐ฎ๐ฅ๐ ๐๐ฉ๐ฉ๐ฅ๐ฒ ๐ญ๐ก๐ ๐ฌ๐๐ฆ๐ ๐๐ฉ๐ฉ๐ซ๐จ๐๐๐ก ๐ฐ๐ก๐๐ง ๐ข๐ง๐ญ๐ซ๐จ๐๐ฎ๐๐ข๐ง๐ ๐ ๐ง๐๐ฐ ๐ญ๐ฒ๐ฉ๐ ๐จ๐ ๐ก๐๐ฒ. Horses need time to adjust, as they cannot make a sudden change in their hindgut microbial balance overnight.โฃ

The first thing I would suggest is to ๐ฌ๐ญ๐๐ซ๐ญ ๐๐ฒ ๐ข๐๐๐ง๐ญ๐ข๐๐ฒ๐ข๐ง๐ ๐ฒ๐จ๐ฎ๐ซ ๐ค๐๐ฒ ๐๐จ๐ง๐๐๐ซ๐ง๐ฌ ๐๐ง๐ ๐ฉ๐ซ๐ข๐จ๐ซ๐ข๐ญ๐ข๐๐ฌ when feeding your horse. Finding the perfect hayโaffordable, high-quality, leafy, low-calorie, high-protein, and with an NSC of 10% or lowerโmay be challenging. Prioritize what matters most to you, whether itโs price, availability, or nutritional content. Be prepared to pay more for better quality. If high-quality hay is scarce or too expensive, supplementing with hay balancers may be an option to maintain health. However, focusing on buying good quality hay can mitigate the risk of many health diseases, and allow you to reevaluate how many supplements you're feeding your horse as well.

Overall, forage is an extensive topic that encompasses many different aspects that need to be understood, but following the steps mentioned above will help you choose quality hay for your horse. If you're unsure whether your hay is adequate, meeting your horse's needs, or if you want to learn more about the various factors related to hay, a certified Equine Nutritionist can assist you in this area.โฃ

In the next post, I'll discuss the importance of vitamins and minerals.
