Under weight horse

I look after a friends horse sometimes.

He never really looks like he's carrying enough weight. He's a 17.2 warmblood, but his hip bones are always visible, and he runs light in his barrel. His coat is healthy and shiney, and his ribs are covered, but he just is not thrifty. He's happy and lively, but looks as if he is racing fit, that kind of lightweight.

She is aware he could do with more weight, but we're at a bit of a loss why. He's had a full blood count done in last 2 weeks, everything perfectly normal, not even remotely near any of the max/min values. WEC is less than 30, and Elisa test was negative. Checked for liver fluke too as there are sometimes sheep kept in the field. Field is poo picked regularly and harrowed to keep fresh.

He's kept on 3 acres of good grazing, with his little chum. Out for 10-12 hours a day, and when in has plenty of really good quality hay, and is never without food. He probably gets about 10-12kg of hay at night, but never finishes it (something my lot would never do, leave food). He's currently being fed Alfa-Oil, Spillers conditioning mix and nuts, plus soya oil, unmolassed speedibeet and farriers formula. He's also getting Egusin at the moment, but no real change in him. He's getting almost as much hard feed now as he was in the middle of winter! And TBH, he's not looking any better than he did then. He gets ridden 4/5 times a week, never that hard and a mixture of hacking (slowly, with his 11.2hh friend) or schooling. He goes to the occasional show to do dressage, and has a lesson every other week at home.

He has a happy easy life, kept at home no stress. Brought in if its too hot/wet/too many flies. Friend has owned him 8 yrs, last 6 of which kept at home. Its only in last couple of years we have noticed him not being so thrifty.

We have spoken about scoping for EGU, though he does not show any real signs other than inappetance. The biggest problem is there in no-one nearby who can scope, so would involve either a 2.5 or 3.5hr journey each way. That in itself is not a problem but obviously is a whole day thing, bearing in mind he is not showing any real signs.

The Vet is a bit puzzled too, and agrees that he should be better covered at this time of year, but nothing in any tests is suggesting that there is something wrong.

He was started on the Egusin as he had a couple of episodes of colic recently, neither of which appeared to have any kind of trigger. Both times he was out in the field and his owner noticed him lying down and went to check on him. Neither time was he rolling or trashing, just uncomfortable, and he was given Buscopan and within couple of hours had passed droppings and back to normal.

We have wondered about a course of GG to see if that will help.

Any other suggestions?

If his ribs are covered and he is otherwise happy and healthy then I wouldn't worry too much. Some lanky and angular horses can look at first glance to be a bit skinny but if you condition score them they are actually a healthy weight. I certainly wouldn't be piling any extra hard feed into him. If it is just his hindquarters that are lean then there is always the possibility of a sub clinical issue in the hind limbs which might be worth investigating.
 
Hi, thanks, I would say he is the lower side of 3 BCS. Last year he had more weight on him and he looked so much better, and IMO had more energy. His hips are very square head on and you certainly cant see any tummy on him when viewing from the front. He's light enough that when I ride him I find him 'small', and I don't look lost on him, and I'm only 5'2"!! I find it much harder to ride my Irish sports horse who is 15.2.
 
We are so used to seeing obese horses these days.

My Vet it very keen on keeping horses around the 2.5 - 3.0 on the 5 point weight scoring system - fit and lean, well muscled without excess fat.
 
Do you have any photos of him?

Personally I would look at changing his feed.

Particularly where it concerns the mix. I would remove this completely - cereals are very hard for them to digest and most of it tends to go in one end and straight out the other. I don't particularly like conditioning feeds as they tend to contain an awful lot of rubbish.

I would start by keeping him on the alfa-a oil and speedi beet and to that I would add One mug full of micronised linseed and 2 mugfulls of soya bean meal a day. The Soya bean meal can be increased quite a bit but it shouldn't be necessary, give it a few months and see how you go :)

Have his teeth been done recently? May explain a reluctance to eat a lot of long forage.

Agree with this, so if the horse is between a score of 2.5 to 3 you shouldn't be needing to worry about increasing his weight. However. It does sound like something else may be going on to cause the lack of energy (maybe stiffness) and muscle wastage over the hindquarters.
 
Whilst I totally agree, horses shouldn't be obese, they also shouldn't be underweight, especially this time of year and with everything he is having to eat, plus his light work, he should be overweight, not thin.

I think, giving the fact that he has had two episodes of colic, that there could possibly be some underlying cause, maybe he's not digesting his food properly?

I would also cut down the mix and feed a good quality balancer, ie Blue Chip, and some micronised linseed, plus some good quality chaff that contains alfalfa. Maybe, speak to one of the feed advisors?

I hope he's ok and you get to the bottom of this.

But according to the OP the horse is the lower side of condition score three, so is actually a healthy weight and isn't thin or underweight.

However, As mentioned previously I would be more concerned about the other issues described than the fact he is a low condition 3.

The other cause of unthriftiness can be stress - is he relaxed and easy going, living out? I know how hard it is, I have an ex Irish chaser who is only 13 but despite adlib haylage, yeasacc, good grazing can't even get enough top line on him to carry a saddle. I can't find anything else for him, he has linseed and a good feed daily, clear egg count but although his ribs are covered, that's it. I'll be interested in the replies you get on here.
 
Thank you for the input. Whilst I agree that many many horses are overweight these days, this horse is definately underweight. His recent small weight gain has been because the owner has increased his hard feed back to winter levels.
He does not have muscle wastage on his quarters, more that his hips stick out in a very angular way, and he has significant dips in front of his hips. I would described his body shape as herring gutted.
After a chat last night, we will look into linseed for him and are going to discuss the possibility of a GG trial, as she feels he has improved on the Egusin.

In comparison, I got a new livery in March, a pure TB, who arrived very underweight and a bit stressed. I have much lower quality grazing than my friend, and yet this horse, through ad lib haylage, has regained all his weight and looks positively tubby now! I hardly give any hard feed either.
