Did your vet instruct you to syringe feed? If she is eating, drinking, and pooping, I think a blockage is really unlikely (plus you already visited the vet). You should offer her anything she would like to eat (hay and veggies) on her own (not sure if you are worried more about syringe feeding or offering her food in general). If she’s eating a good amount then I don’t think you need to syringe feed, but keeping food going into her is crucial for stasis treatment.
I think since you already went to the vet, your vet probably already assessed for a blockage. I’ve also asked my vet about this, and he said that in many cases where a partial blockage is suspected, the treatment is the same as he used hydration and food to try to move the mass through. (Different than a case of bloat though).
