I posted this on another thread:
Sentinel Active Senior (AS) and Performance LS are similar with 12% fat vs 5.5% in Senior.
Fiber is 15% maximum in AS and 20% max in LS. The diifference is that the minimum fiber in Senior is 17%.
If you look at the feeding directions on the website:
Senior has a Maintenance level of .40-.65 lb/100 lb of body wieght. Light exercise is .45-.65 lb/100 and Moderate is .55-.75
AS and LS don’t have a Maintenance level. Light exercise is .40-.60 and Moderate is .45-.70. They have heavy and very heavy levels.
Senior recommends changing to Active Senior for Heavy exercise and Hard Keepers.
Senior also has Diets with Minimal Hay for Maintenance 1.00 - 1.25 lb/100 body weight. That is where the 5.5% fat comes in. 10 lbs of 12% fat (LS and SA) is way more calories compared to 10 lbs of 5.5% fat (Senior).
All three weigh .85 lb/quart.
My horse was about 1100-1150 lbs. His teeth were in good shape so he didn’t have a problem with hay. That is why he was on LS and AS. I fed him his grain at our original barn but he wasn’t getting enough hay. We retired to a stall with runout at a luxury barn. I kept him on Blue Seal; the barn fed another brand. The BO was meticulous about feeding each horse. She got him back to excellent condition with normal body weight.
I figured he should have about 6 lb/day and there were 3 feedings. That is about 2-1/4 quarts/meal. I got him a pitcher-style scoop and put his name on it. I weighed the grain and marked the scoop. It stayed in his grain bag. If you rely on the usual scoops with the handle you don’t know what you are feeding other than a “scoop” which measures volume. That’s usually okay until they start aging, their teeth start wearing out, and their nutritional needs start to change.
The new barn’s grain room had 2 white boards. One had scheduling - my horse got b’fast grain and supplements, supper grain, and late night grain. The other one had recipes and hay: b’fast was one scoop of grain, one bagged supplements. They hung onto old SmartPak drawers for bagged supplements. The barn changed hands but the new BO stayed with that plan. It sounds more complicated than is. Once I figured out what my horse needed it didn’t make any difference who fed them, as long as they used the white boards.
When I had to put him down in July his body weight was normal and his coat was shiny. He was a bundle of energy. It was tough because he looked so good, but not so bad because he wasn’t a ribby raggedy old man.
I looked at several websites before I decided to stick with Blue Seal. A big reason is the amount of information they post and you can compare products on one screen.
