Adding timothy pellets to his diet

I have an 8 year old thouroughbred who could use an extra 50 pounds on him.

I had been feeding him just Triple Crown Complete, with all his supplements once a day, and obviously he gets hay in the morning and evening.

My BO suggested I add Timothy Pellets and Rice bran oil to his diet. So I started feeding him that too and I broke it up into two feedings.
I just want to make sure Im giving him enough of both.

In the am he gets 1 1/2 scoops of Triple Crown, and a scoop of Timothy pellets with one scoop of all his supplements.
In the evening he gets 1 1/2 scoops of Triple Crown and 1 scoop of Timothy pellets with one scoop of electrolytes.

Does this sound right? He gets about 6 pounds of Triple Crown all together. Is it right to mix the pellets with the triple crown?

Also I feed him his morning feeding cause I am there, but I rely on the BO to feed him his evening meal, which I don't think she is doing all the time, she forgets things.
I would feed him the second feeding but I live to far and with gas prices its hard enough to go out once everyday let alone twice, so that's why I make sure to put all his supplements in his morning feeding.

How bad would it be to give him just one feeding? I want to make sure he gets all the food for the day since he needs to gain, but like I said sometimes I come to the barn and his evening meal hadnt been fed the night before. (just to clarify its just the extra feeding, he always gets his hay twice a day)

I will eventually switch barns but for now this one is in my price range and except for her forgetting sometimes, I have no other complaints.

What should I do?
Sorry for the lenghty post

Oh sorry also wanted to ask is 2 scoops all together of Timothy pellets good? Should he get more or less? And is it good to mix it with the triple crown or should I just put the pellets seperate in his feed bin?

Thanks agian!

Two feedings are always better than one, but consistency is also very important. It's hard on their guts to process that much food at one time if you change to 1 feeding per day...so I wouldn't advise that.

Have you talked with the BO? Could you put a feeding card on the front of his stall to remind her? Can you set his feed out in a ziploc baggy in front of his stall? I know if I had an underweight horse "occasionally forgetting" his second feeding would make me livid

The way you have it broken down sounds right, and you can mix the pellets and TC - although I personally steer clear of too many supplements and daily electrolytes.

I would not give more than 2 scoops of timothy pellets until you've established a consistent pattern of feeding and he acclimates to the change. Then, you may add more according to the label on the bag. :)
