I have a few questions regarding feeding grains such as oats to my Arabian gelding. First off, he'll be 15 years in April, and has been a hard keeper in the winters, unless I really get his weight up during the fall. The problem for me is, I'm always afraid of feeding too much grain, I'm so worried he'll colic if I'm giving him too much. Right now I'm maintaining his weight, (the temperature these past couple winters has gone down to -50 C ) so I give him 3-4 cups of rolled oats with flax seed about three times a week.
Here is something I found though, this website - How Much to Feed your Horse?
...suggests how much grain to feed your horse once you put in their body weight, workload and body condition. Last time I measured my gelding, his body weight was around 960, he might be 1000 lbs now. I do light work with him, and his body weight is normal. The calculations though say to feed him 2.3 kg/5 pounds of grain! I measured my grain on my kitchen scale, and 5 pounds is 16 cups! Wouldn't that be too much? I have an 8 quart feed bucket, and the suggested amount of feed almost fills it full. Plus since he's an Arab, he does tend to get pretty hot with too much grain.
I just want to feed him properly, but I'm concerned and a little confused, how much is too much, and how much is too little? Any advice would be so greatly appreciated!
