I have been using alfalfa meal for a long time because it contains a growth hormone. To get the meal I ask my feed store to special order the bigger bag. Right now that is double the price of horse pellets. I have debated which route to go. I have success with the meal and it does not attract rodents or wild life. I slightly dampen it so it is not a flyaway and stir it into manure or compost. Besides the wild life issue, the reason I will stick with meal is because it is not processed. I think the growth hormone would be better closer to the natural younger state of alfalfa. Usually the premium young prebloom alfalfa hay is what is turned into meal. It is the most nutritious. Older alfalfa hay becomes the pellets, and it's nutritional value is way different. I could not find a scientific study that proves the the growth hormone Triacontanol is unchanged in the pellets. If anyone has any info on nutrition and pellets, I would like to read and learn! Many blessings for a joy and happiness in your life!
