We have got some rain this year but our grass is not growing very well. we have 150 acres with 60 head of cows and there is not enough grass there last year we had more than enough grass. we are getting them some hay today it is good grass hay plus some grain question is will they still keep there weight and gain it as well it is freshly cut hay with a good amount of protein in it. i am hoping they will gain just as much on the good hay as they would on green grass. sorry for the questions but this is the first year that we have had to feed hay during the summer time. thanks
