Question about Alfalfa plot

[wolfcliff]

I planted an alfalfa plot right at 6 weeks ago in mid MO. Morgan County. All went great with the drought ending and abundant rainfall to get everything up and going great. My Question is with 20+ deer in this plot day and night. Will it survive winter if all new growth is being grazed on constantly? Anyone have experience with this fall planted, and mowed to a turf. The crowns look OK, and about 2 weeks ago I went in and harvested a buck that i had watched all summer we called Spidey. (web Horns) At that time some of the plants were about 8 inches tall that hadn't been grazed on. Went back last weekend and deer are in this 5 acre plot all hours of the day and night. Looks like a golf turf except for a few weeds that are VERY apparrent standing above alfalfa turf.
Thanks ,
