I'd have the syringes on hand, for eventual emergencies. If he always has hay or grass available, he shouldn't need the pellets daily.
As for the 4 cups....I give two handfuls with RB....that's a whopping 3 oz lol. So if he's not gaining, upping the alfalfa could be in order. My TB refused to gain the last 50 lbs needed until I fed soaked alfalfa- pellets, a tiny bit of wheatbran, to balance Ca:Ph, a little corn and barley, about a lb each and flax and soybeanmeal, 50 grams each. Then he started packing it on, topline and all. That was before feeding grains to horses was considered bad, tho
Glad you mentioned the balancing act of feeding x.x this is killing me... If he's getting the RB, and the alfalfa pellets won't his Ca:Ph:Mg ratios all be off? I'm mostly concerned about his MG ratio, as you helped me to find my mare's ratio was very off. She's on just the RB, just 1 pounds (she should have 1.3 but she's SO fat!). So do you think the alfalfa is going to throw off his ratios? If so how can I balance out the Ph and Mg?
How long should I use the u-gard for? How do I know when/if he's feeling better - he's a seriously stoic horse and doesn't appear in pain with grooming, but when she ran the cap on him he just about fell down - she said it was the most extreme reaction she'd ever seen. I'm not sure how to do what she did to see if he's feeling better?
