I have a 8 month old brahman- longhorn cross that I purchased when she was 3 months old. Been small since we got her. Looks the same size today as when bought. Seems to have been sick since then as well. I have treated her and so has the vet, but still a runt. Gets grass, hay, and a mixture of 3 way, calf manna , and cotton seed meal. Any suggestions on how to get her up to speed? Kinda new at this so anything helps!
