Melissa, I would most definately let the little boy continue nursing on Jenna and then put him with the other mom for a extra snack then bring the pup back to Jenna.
The pup needs to continue nursing Jenna so that she won't completely dry up. I'd take her to the vet tomorrow for a checkup to make sure that there isn't a medical problem. I know you are already doing this so continue working with Jenna to get her to eat and drink so that she has what she needs to produce milk. On the other hand, I wouldn't want to put too much stress on the other mom if she isn't producing much milk either.
I can't really advise about the Nutra-Cal. I am sure that others here are more knowledgeable about it's use. I do know that Dr. Amy has cautioned me to ALWAYS make sure that they eat after taking Nurtr-Cal because it causes a quick rise in the blood sugar level and a quick drop about 20 minutes later.
We saved a foal once by letting her nurse on a foster mom. It was very time consuming but it worked. We didn't want her birth mom to dry up, but she didn't have enough milk so..... We brought both mares and foals into the barn and every 3 - 4 hours round the clock for a week or so (it seemed more like months) we would take the little one across the hall to his "milk momma" and let him nurse and then back across the hall to his real mommy. Every one was happy and the foal thrived. Eventually the birth mom developed enough milk to support the foal. The milk mamma mare loved babies and would often nurse other foals out in the pasture. |
