Is their any risk of moving cows 10 miles in a trailer within a month of calving?
No, but it is important that they be handled with care. Make sure that the pregnant cows are not worked at a fast pace and that the alley-ways and loading areas have good footing so the they do not slip and fall. Also, do not pack the cows to tightly in the trailer. Make sure that the loading area gates are opened as wide as possible and do not rush cows through these openings.
