So I am looking for some advice on a complete feeding change for my mare. She is a 4yo QH that is 16'1hh that is built like a Tb and is about a 4 -5 on the body condition scale. She is being brought up as a hunter, and her work load has been increasing over this summer. She is at a boarding barn, but I have decided to take complete control over what she is being fed. She has always been a little thinner than I would like, but it's worrying me because between last weekend and this weekend when we went down to the trainers my trainer could see where she had lost weight, and another person who hadn't seen her in a while also commented that she looks thinner. I am sure the horrifically hot weather in TX is not helping, plus I don't think she is getting enough calories for her size, workload, and growth.
Right now, she is on a locally made feed that is 14% protein, 6% fat, and 10% fiber. The amount is about 2.5 quarts twice a day. She gets one flake of a grass type of hay in the morning, two at night. In the evening, I feed her a mixture of beet pulp and alfalfa pellets soaked afterwards, 3 quarts beet pulp, 1 quart alfalfa pellets. She is on one supplement for ulcer prevention (never truely diagnosed, she just had a few stomach aches and was moody, was started on this and knock on wood hasn't had a problem since - Ulc-R-Aid by Animed).
I am in TX and hay is becoming in very, very short supply and I am worried about the barn running out. It is running at $10 a bale right now for grass hay, so it is hard to feed large amounts of hay, which is what I would love to do. I am trying to stock up on a personal supply of hay, but I really can't increase the amount so I am looking at other options for weight gain.
The brand options I have are:
I have used Strategy effectively in the past when I had my horses at home. My trainer is using Safe and Sound by Acco currently, while another friend has switched from the feed my mare is currently on to Total Equine with a good improvement. I am open to mixing some of my own feed if I can find the info on how to mix it currently. Options I have to do this easily are the beet pulp, alfalfa pellets, timmothy pellets, cracked corn, rolled and steamed oats, stabilized rice bran.
I have just started looking at basic analysis (not nutrients, just protein, fat, and fiber). I am thinking that I want to keep her at about 14% protein as she is still growing and building muscle, increase the fat, and increase the fiber if possible. Here are some that I am interested in, including the ones I/trainer/friend have some experience with.
Safe and Sound - 14/7/15
Strategy - 14/6/12.5
Total Equine - 15/5/20
Ultium Comp - 11.7/12.4/18.5
Ultium Growth - 15.5/9.5/13
Triple Crown Growth/Senior - 14/10/17
Triple Crown Training - 13/13/13
Triple Crown Performance - 14/10/6.5
Nutrena Safe Choice - 14/7/15
What ideas do you guys have? Any resources that you guys know about that is good to read up on equine nutrition? I have a good basic knowledge of human nutrition, but not equine. Sorry this is so long, I know I can be long winded and nerdy at times. And thanks for the help in advance.
