Too Young ?

So I have a Kiko/Boar cross buckling a twin ... 3 weeks old. He isn't gaining weight like he should, walks with a hunch and past few days eating a lot of grass. His Dam last year had Triplets and rejected feeding one and the other 2 are now yearlings and small compared to the others we have. She doesn't produce a lot of milk. Tried getting a temperature but both digital thermometers we have now don't work even with a battery change. Trying to find one right now is impossible ... Brought him in the house to make sure that he is warm enough and he is resting comfortably.
He seems OK but just wanted some advice about maybe giving him a SQ shot of Thiamine HCI to maybe help him out. Mine is 500mg from the vet and he gave me dosing @ .75 ml per 100#. This little guy is just 10#7oz so would anyone suggest giving it to him and dosage @ about .10 ml ... Very small amount in my syringe ... Comments

 

Wife and I were just talking about not breeding her again ...

 

Thanks for the info .....
I will try and get another thermometer tomorrow while in town. We took him back out a few hours ago and just coming in the house. He was out in the pasture with mom and sister and both were nursing. I will see about getting a fecal done also. Checking eyelid as in pink not white ? He doesn't seem seriously sick ... Just a bit off from the rest .... We have 14 kids between 1 and 3 weeks old.

 

Ok so I am back to this issue again. Ordered a new thermometer as the panic has made it impossible to find one. Temp taken yesterday and today ... 101.6 & 102.4, just got back from vet and fecal is negative for parasite or worm issues. Eyelids are pink.
He has developed diarea the last 2 days. We are giving him to drink a water,molasses, baking soda and cloves mixture to keep him hydrated. He is now just 4 weeks and has gained almost 4#. We watch him nurse and he is eating grass ... I have given him 2 shots of thiamine so far. I am almost thinking that he may have some development issues ? Any other Ideas ? Thank You for your help

 

No he is nursing and drinks from the bowl

 

Thanks for the response ... He is done with the molasses mixture ... Won't touch it now but I believe that he learned to drink water at least using it. The stool seems to have firmed up today so hopefully that is it. The stool was black. They told me that they checked for coccidia first and then checked for worms and all was good.

 

Thanks ... He now seems to be getting better each day. I do have Wind and Rain free choice as well as a mineral salt block ... Loose salt also ? How about baking soda ... I have seen some also do free choice with that ... Definitely the diarrhea / scours have stopped ... Clean rear yesterday and today ...

 

... We keep a mixture of alfalfa pellets, oats and black sunflower seeds for them ... they are not overly eager about it ... What else would you suggest ?

 

I will look for something like that next time in town ... Thank You
