LaLa is the big dairy outfit in Mexico. When I was working in Torreon, we drove past several of their dairies each day. Approx 5k head per set up. All dry lot. Alfalfa was grown in long strips. Flood irrigated. The strips were exactly 6x the width of the cutter head on the swather. Swather would make 3 trips down the field and back. Move to the next strip. I did not see any alfalfa being baled. Only saw green chop in the back of two and three axle trucks being moved to the cows. IIRC, they said 10 to 11 cuttings per year. 3 weeks per cutting in warm weather. 4-5 weeks in cool weather.
