NASHVILLE (AP) — The 2012 directory of hay producers in Tennessee is ready, and agriculture officials say it is coming just in the nick of time for some livestock farmers.

The drought and heat wave are making the annual publication even more useful this year. Agriculture Commissioner Julius Johnson said many farmers are already feeding hay to cattle, horses and other livestock at a time they normally would be putting away bales to use next winter.

The directory is produced in tandem by the state Agriculture Department and the Tennessee Farm Bureau and available online. It lists growers, hay variety, quantity and bale type. Some growers also provide protein and other nutritional information based on University of Tennessee Extension testing.
