I bought cattle from Colorado and moved them to mo. they calved within six to 8 weeks and have continually lost muscle. they act alert and fine, the calves at 6.5 months look great and are still on the cow. they are on a continual hay / a little grass, whats left / sweet lick tank. they have a mineral also avail. at all times. they have fresh well water and a pond to drink. my other cattle on the same diet are doing great. i know environment change is hard to adjust to, but how long usually? it has been 10 months. thanks for any help you may offer.
